In recent years there has been rapid growth of education in Earth Sciences with new ideas and approaches that not only addresses earth’s origin and evolution but also plays a key role to understand the most important issue of climate change and assess our success in training our society for future environmental changes. The subject has charmed many students to pursue rewarding career in Earth Sciences. It is all about using an interdisciplinary approach to comprehend our Earth System to unravel the geological record from different components of the Earth. Our faculty is continuing the interdisciplinary research work aimed at producing high resolution geological records from India and world as well. They are involved in teaching through effective methods in the classroom, laboratory and field so that our students leave with skills and ability to work independently as well as in the multi-disciplinary teams to apply the knowledge of geosciences and meet the desired targets. During the last five years UG and PG syllabous have been revised and one new 5 yr integrated PG course has been started from the years 2009. As per the MHRD directive, the Department has revised its undergraduate syllabus according to the needs of Choice Based Credit System. In, addition modernization and up-gradation of the class room and laboratory has been taken up on priority level to improve students’ learning in the department. Other facilities generated for teaching and research include:

(i) XRD and SEM Labs with new equipments are fully functional.(ii) State-of- the -art Petrology Lab (iii) Experimental Structural Geology Lab

A brief overview of work done by the individual Faculty Members and their group related to the thrust areas is given below:

A. Petrology, geochemistry and Tectonics

Highlights of the work done by Prof.Anupam Chattopadhyay:

During the period under review (2011-16), I was mostly involved in structural modeling of continental shear/fault zones through fieldwork and experimental modeling. The work done on Gavilgarh-Tan shear zone in central India has revealed that this terrain-bounding shear zone underwent transpressional deformation in Meso-Neoproterozoic, which partitioned into simple shear and pure shear components (Chattopadhyay and Khasdeo 2011). Two types of pseudotachylyte veins (Pt-M and Pt-C) associated with sheared granitoids of GTSZ have been dated in collaboration with the Open University, U.K, and show two fault reactivation events – in Neoproterozoic and Ordovician. These pseudotachylyte vein systems were mapped in detail at outcrop scale and the structural data was used to interpret the seismic source parameters e.g. seismic moment, maximum shear stress at rupture etc. On the basis of these data an estimated paleo-earthquake magnitude was suggested (Chattopadhyay et al. 2014a). The control of polyphase deformation on the gold mineralization in Bhulia-Jagpua belt in Rajasthan, has been worked out (Deol et al. 2014). The Experimental Structural Geology Laboratory has been further expanded, with one post-doc scientist and a few research scholars regularly working with this facility. Experimental investigations on rift faulting, on strain patterns in a transpressional system and on the evolution of thrusts in a contractional orogenic belt have been carried out here. Three major international papers have been published by my research group from the experimental modeling studies (Chattopadhyay and Chakra 2013, Ghosh et al. 2014 and Chattopadhyay et al. 2014b). Monazite dating of deformed and undeformed granites intrusive into the metasedimentary Sausar Group in central India has helped constrain the timing of a major collisional orogeny in Neoproterozoic (Chattopadhyay et al. 2015). In total, I have authored/co-authored eleven peer-reviewed research papers in national and international journals and seven abstracts in conference proceedings during this period. Studies on active faulting in Gavilgarh Fault Zone, central India has just been concluded, on which one Ph.D. student has submitted thesis. The results have been reported in major international/national seminars and one full paper is under publication process.

a. Significance of viscous folding in magma mixing.

33

Mixing between mafic and felsic magmas in shallow level magma chambers is considered as a primary factor triggering volcanic eruptions. Recent developments in microfluidics have enabled us to better understand the complex processes associated with magma mixing from the hybrid rocks of the Ghansura Rhyolite Dome (GRD) of Proterozoic Chotanagpur Granite Gneiss Complex (CGGC), Eastern India.

The hybrid rocks from GRD have formed due to the mixing of a phenocryst-rich basaltic magma and host rhyolite magma. The hybrid products have preserved amphibole-rich microzones (ARM) in contact with fine grained felsic zones. The ARM dominantly consist of amphibole surrounded by other mineral phases like biotite and plagioclase. Amphibole crystals occurring in the core of ARM are actinolite, while those occurring in the rim are of hornblende composition. Veins of amphibole have been observed moving out from the ARM into the felsic zones. An interesting feature about the amphibole veins is that as they venture into the felsic zones amphibole converts to biotite, and also the veins undergo viscous folding. Amphibole display pargasite substitution from the core of the ARM to its margin and further extending into the veins where the mineral is completely replaced by biotite.

From mineral chemical, textural and thermometric analyses we infer that when mafic magma, containing phenocrysts of augite, came in contact with felsic magma the two remained as separate entities at first due to pronounced thermal and rheological contrasts. The first interaction that took place between the two phases is diffusion of heat from the hotter mafic magma to the colder felsic magma followed by diffusion of elemental components between them. The diffusion of cations from the felsic to the mafic system like H+, Al3+ and other cations reacted with the clinopyroxene phenocrysts in the mafic magma to form amphibole crystals. The formation of amphibole crystals in the mafic system greatly increased the viscosity of the system allowing the amphibole crystals to venture into the adjacent felsic magma as veins. As these veins traversed in the felsic medium, they were acted upon by compressive stress and underwent viscous folding to enhance mixing between the two magmas.

b.Sphene-centered ocellar texture as a petrological tool to unveil the mechanism facilitating magma mixing.

The sphene-centered ocellar texture is a unique magma mixing feature characterized by leucocratic ocelli of sphene enclosed in a biotite/hornblende-rich matrix (Hibbard, 1991). The ocelli usually consist of plagioclase, K-feldspar and quartz with sphene crystals at its centre. Although geochemical and isotopic data provide concrete evidence for the interaction between two compositionally distinct magmas, the exact processes by which mixing takes place is yet uncertain. So, textural analysis can be used to decipher the behaviour of two disparate magmas during mixing.

Presented work is being carried out on the sphene ocelli, occurring in hybrid rocks of the Nimchak Granite Pluton (NGP), to understand its formation while two compositionally different magmas come in contact and try to equi- librate. The NGPis ca. 1 kmin extent which has been extensively intruded by number of mafic dykes exhibiting well preserved magma mixing and mingling structures and textures in the Bathani Volcano-Sedimentary Sequence (BVSS) located on the northern fringe of the Proterozoic Chotanagpur Granite Gneiss Complex (CGGC) of eastern Indian Shield.

From petrographic and mineral chemical studies we infer that when basaltic magma intruded the crystallizing granite magma chamber, initially the two compositionally different magmas existed as separate entities. The first interaction that took place

34

between the two phases is diffusion of heat from the relatively hotter mafic magma to the colder felsic one followed by diffusion of elemental components like K and incompatible elements from the felsic to the mafic domain. Once thermal equilibrium was attained between the mafic and felsic melts, the rheological contrasts between the two phases were greatly reduced. This allowed the felsic magma to back-vein into the mafic magma. The influx of back-veined felsic melt into the mafic system disrupted the equilibrium conditions in the mafic domain wherein minerals like amphibole, plagioclase and biotite were crystallizing. This led to the incongruent melting of amphibole and biotite to form liquids of sphene composition. Meanwhile, plagioclase continued to grow in the mafic-turned-hybrid system with a different composition after the advent of felsic melt as indicated by compositional zoning in plagioclase crystals. The newly produced sphene-liquid, owing to its higher affinity for felsic phase than mafic, got incorporated into the back-veining felsic melt forming a distinct liquid of its own. The felsic melt also incorporated crystallizing plagioclase grains in it from the mafic matrix. The mixture of felsic melt, sphene-liquid and plagioclase crystals flowed through the biotite, amphibole and plagioclase dominated matrix towards the low pressure zones to occupy the spherical void spaces left behind by escaping of gases/volatiles forming the sphene ocelli.

Stratigraphy, age and duration of Deccan volcanism:

Combined field, petrographic, and major element studies resolves that this lobe comprises 37 lava flows and using a combination of trace elements (Ba, Ti, Zr, Rb, Sr) and Nb/Zr values, we group the flows into six chemical types (A–F) that are separated stratigraphically. Combined trace element and Nd-Pb-Sr isotopic data, document the presence of lavas resembling those of the Poladpur Formation and less abundantly, the Ambenali Formation of the southwestern Deccan. In addition, our data reveal several flows similar to those of the Mahabaleshwar Formation. Based on the isotopic data the superposition of Mahabaleshwar-like flows over flows withAmbenali- and Poladpur-like characteristics is in the same stratigraphic order seen in the southwestern Deccan type section.However, from the stratigraphy indicated by the Discriminant Function Analysis (DFA) results and the serious discrepancy between the DFA and isotopic data, it seems that few Mandla lobe flows are different and not in the same stratigraphic order as in the southwestern part of the province. To some extent the differences may be explained by faulting along four large post-Deccan normal faults near Nagapahar, Kundam, Deori, and Dindori areas across which offsets of ~150 m have been measured.

New age determinations, derived from 40Ar–39Ar incremental heating experiments, for basaltic lava flows from the Mandla lobe, located on the eastern margin of the main Deccan volcanic province, some~1000km from theWestern Ghats escarpment. The most reliable estimates of crystallization ages come from5 plateau ages from plagioclase separates, from a stratigraphically controlled succession of 37 lava flows. We detect no statistically significant age difference from bottom to top (range 63–65 Ma) and calculate a weighted mean age for the section at 64.21 ± 0.33 Ma. These lava flows are significantly younger than the majority of the main Deccan volcanic activity documented from the Western Ghats (67–65 Ma). The new ages are consistent, however, with geochemical correlation of the Mandla lobe lavas with the uppermost succession

35

(Poladpur–Ambenali–Mahabaleshwar Formations) of the SW Deccan, and indicate that this post K/PB youngest phase of flood basalt activity erupted over much of the province.

a. In Central India not only we have been able to identify a UHT metamorphism at ~ 1.6Ga but have also demonstrated that this caused changes differently in accessory minerals such as monazite and zircon (Geological Journal, 2010).

b. From an Archean Craton (Bundelkhand), we have been able to demonstrate conditions of mineralogical transformation which would have been only possible at depths greater than 70 kms or high pressure conditions. The significance of this HP event is that we have dated monazite which overprint this fabric and reflect two growth ages- 2.78 and 2.45 Ga. Thus, this represents first report of processes akin to present day subduction from any Indian Archean domain (Contribution to Mineralogy and Petrology, 2011). Further work (unpublished) from this cratonic block has shown ~2.5Ga continent-continent collision signatures.

c.From Dharwar craton also we have reported for the first time a granulite grade metamorphism in EDC at ~2.62 Ga (Geological Journal, 2011).

d.We have dated 3 billion year old monazites in metapelitic granulites. The sample is from the interface of a Proterozoic orogenic belt (Eastern Ghats Mobile Belt or EGMB) and an Archean craton (Singhbhum craton). The former is considered a granulite terrain of ~ 1.1 Ga age while the latter is a granite-greenstone terrain of Archean age. Using petrological and geochronological evidence we have demonstrated these to be lower crustal component of an Arcehan craton. (Geological Journal, 2012)

e.I have attempted to carry out the bulk chemical characterization of micro domains in thin sections to understand the geological processes. Electron beams of 50, 20 and 1 micron meters were calibrated as well as employed to analyze in-situ micro domains (scales of tens of microns). This allows computation of effective bulk compositions and can be used in understanding features such as coronas. We employed this technique in pseudotachylites to demonstrate disequilibrium melting and also to show formation of two different melts in close proximity (Contribution to Mineralogy and Petrology, 2011).

f.In a combined sedimentological-petrological study we have demonstrated that two synchronous Proterozoic basins (Gwalior and Bijawar) sourcing from same provenance produce dissimilar sequences indicating a strong basin level control on deposition (Geol. Soc. London Book Chapter, 2015).

g.Suturing of east and west Gondwana is a significant geological event and is well marked in African continent by the East African Orogen (EAO). However, its southward continuation is still not well understood as its projection in east Antarctic shield divides this craton into two distinct geological entities. Our recent work using petrological and geochronological data shows landward extension of EAO in east

Nuclear Waste Management:

Nuclear waste loaded and natural (analogue) glasses were studied to understand neo-formed mineral species, formed in equilibrium with the physico-chemical conditions existing in the geological repository. To predict alteration-phases, dissolution equations for average vitrification system (AVS), barium borosilicate (BBS) and obsidian glasses were calculated, considering glass composition, pressure, temperature and pH conditions. Progress of reaction plotted against saturation index indicates saturation with solid phases – chamosite, chalcedony and Ca-beidellite in obsidian; greenalite and fayalite in AVS; and coffinite in BBS glass. Activities and molalities of aqueous species together with the number of moles of each mineral species produced and degenerated during the progress of the reaction (as a function of time) are discussed here.

Deccan basaltic glass is associated with the differentiation centre of the vast basaltic magmas erupted in a short time span. Its suitability as a radioactive waste containment chiefly depends on alteration behaviour; however, detailed work is needed on this glass. Therefore, the basaltic glass was treated under hydrothermal-like conditions and then studied to understand its alteration. Moreover, comparison of these results with the naturally altered glass is also documented in this paper. Solutions as well as residue obtained after glass alteration experiments were analysed. Treated glass specimens show partial to complete release of all the ions during alteration; however, abundant release of Si and Na ions is noticed in case of almost all the specimens and the ionic release is of the order of Na > Si > K > Ca > Al = Mg > Fe > Mn > Ti. Scanning electron images of the altered residue show morphologies of smectite, montmorillonite and illite inside as well as outside of the secondary layers, and represent paragenesis of alteration minerals. It has been noticed that the octahedral cation occupancies of smectite are consistent with the dioctahedral smectite. The secondary layer composition indicates retention for Si, Al, and Mg ions, indicating their fixation in the alteration products, but remarkably high retention

37

of Ti, Mn and Fe ions suggests release of very small amount of these elements into the solution. By evolution of the secondary layer and retention of less soluble ions, the obstructive effect of the secondary layer increases and the initial constant release rate begins slowly to diminish with the proceeding time. It has been found that devitrification of glass along the cracks, formation of spherulite-like structures and formation of yellowish brown palagonite, chlorite, calcite, zeolite and finally white coloured clays yielded after experiments that largely correspond to altered obsidian that existed in the natural environment since inception ~66 Ma ago.

Obsidian glass alteration experiments under near hydrothermal conditions were performed to study mechanism and conditions of formation of altered minerals. X-ray diffraction patterns and cell dimensions of the specimens treated at 150, 200 and 3000C (pH = 8.03) revealed appearance of three main minerals - illite (9.5-10 Å), chlorite (7.04 Å) and halloysite (10.25Å). Further increase in the pH favours matrix dissolution with the formation of secondary altered layers. SEM-EDS study show that the alteration causes smoothing of the grain surfaces. These surfaces exhibits etch pits and series of depressions, formed by the process of dissolution. SEM - Back Scattered Electron images of obsidian specimens show thin laminae of smectite, with foliated bulky rims and cellular honeycomb texture, formed by precipitation from the solution as well as by direct transformation of glass during alteration. This mechanism is resulting from the alteration of alkalis by ionic inter-diffusion with H3O+ and H+ and inward diffusion of H2O, leading to free diffusion of silica into solution and then to a local rearrangement of the glass framework. Thus, a direct transformation of glass into clay minerals is the major reaction mechanism as evidenced by the mechanism of glass dissolution and subsequent mineral precipitation. conditions. Neo-formed minerals were compared with naturally altered minerals to assess its performance.

Altered specimens show partial to complete leaching of glass, where ionic release is of the order of Na>Si>K>Ca>Al = Mg>Mn>Ti. SEM-BSE images show distinct microstructures and mineral paragenesis of smectite, chlorite, nontronite, and illite inside and outside of the secondary layers - show retention of Si, Al, and Mg ions, fixation in the alteration products after their meager release to the solution. Secondary minerals-palagonite, chlorite, calcite, zeolite and white colored clays - formed after experiments largely correspond to altered obsidian in the natural environment since ~ 65 Ma.

CO2 Sequestration:

Rock specimens from Deccan flood basalts have been reacted in the laboratory under high pCO2 (5 and 10 bars), total pressure (vessel pressure between 10 and 20 bars), and temperature (100 and 200°C) conditions for 50, 60, 70, and 80 hours. XRD and SEM-EDS analyses show that calcite, aragonite, siderite and magnesite, and clays are derived from the alteration of Deccan basalts under water-saturated, hydrothermal-like conditions. Alteration reactions were accompanied by significant variation in the pH of the reacting aqueous solution, dependent upon time, pCO2, and temperature variables of the experiment. Neo-formed secondary products also include significant amounts of smectite, chlorite, and smectite/chlorite mixed layer clays.

a.In inaccessible areas (e.g. sub-ice areas in east Antarctica) ocean sediments reflect the geology of the provenance as well as the processes that leads to sediment formation and deposition. Essentially using mineralogic approach, we have been able to infer the nature of geology of eastern Wilkes Land in east Antarctica and also been able to comment on the processes (including climate variability’s) leading to the deposition. (Geological Society of London Special Publication, 2013; Int. Jour. Earth Sciences, 2014). One Ph.D. from this work has already been awarded. We have also inferred a major bollide impact in Wilkes Land basin based on meteorite fragments recovered from ocean sediments (Under review).

b.Taking this approach a step further for the study of Quaternary sediments in the Himalayas, I have recently been awarded a project worth ~98 lakhs by Ministry of Earth Sciences.

c.North Delhi Fold Belt (NDFB) represents a significant Proterozoic ororgenic belt in northwest Indian shield. It also contains significant sulphide mineralization. We were first to date the metamorphism in this belt in 2008. In a still continuing work we have now constrained the metamorphism and mineralization both of which are of more than one generation and we have identified a Neoproterozoic contact metamorphic effect which is mainly responsible for the relatively enriched mineralization (Episodes, 2013; Geol. Surv. Ind. Sp. Publication, 2015). In course of this work we have used mineralogical approach to document sub-greenschist facies metamorphism in the Raialo Group and proposed that these rocks are not part of the Delhi Supergroup (Jour. Geol. Soc. Ind., 2015). One Ph.D. from this work is submitted.

d.In Himalayas, one of the youngest orogen, we are looking at eclogites mainly from the point of view of deducing the processes and geochemical pathways involved during the transit of crustal rocks to depths of over 150 kilometers and their subsequent exhumation. We have modified the P-T-t path for these rocks using mainly the amphibole compositions (Int. Jour. Earth Sciences, 2014). In eastern Himalayas, a dual P-T path was worked out in the LHS sequence located in the footwall part of the MCT in western Arunachal Himalaya (Lithos, 2014).

Clay minerals record from Late Quaternary drill cores of the Ganga Plains and their implications for provenance and climate change in the Himalayan foreland: This study documents the coupling of provenance and climate change over the last 100 ka manifested in clay mineralogy of sediments from two cores (~50 m deep) in the Ganga–Yamuna interfluve in the Himalayan Foreland Basin, India. Depth distribution of the texture and clay mineral assemblage in the two cores show notable differences on account of pedogenesis and sediment supply over the last 100 ka. Core sediments from the northern part of the interfluve (IITK core) are micaceous and dominated by hydroxyl-interlayered dioctahedral low-charge smectitea (LCS) in fine clay fraction but by trioctahedral high-charge smectite (HCS) in silt and coarse clay fractions. In contrast, core sediments from the southern part of the interfluve (Bhognipur core) are poor in mica and both LCS and

39

HCS are recorded in the upper 28 m of the core while the lower part is dominantly LCS in all size fractions. The paleosols in the two cores formed in the sub-humid to semi-arid climatic conditions resulting in clay minerals such as 1.0–1.4 nm minerals, vermiculite, HCS and also preserved the LCS, hydroxyl-interlayered vermiculite (HIV) and pseudo-chlorite (PCh), and kaolin that formed earlier in a humid climate. The preservation of LCS, HIV, kaolin and PCh is a clear indicator of climate shift from humid to semi-arid in the Ganga Plains as their formation does not represent contemporary pedogenesis in the alkaline chemical environment induced by the semi-arid climate. As the simultaneous formation of both HCS and LCS is not possible at the expense of mica, the abundance of LCS sediments from both the cores suggests the role of plagioclase weathering in the formation of LCS. In the upper 28 m of the Bhognipur core, the presence of both HCS and LCS in the fine clays suggests a change in sediment provenance from cratonic to a dominantly Himalayan source during Holocene. The climatic records inferred from the typical clay mineral assemblages of the two interfluve cores are consistent with the Marine Isotope Stages (MIS). The humid interglacial stages (MIS 5, 3, and 1) are marked by dominance of HIV, PCh, and LCS whereas the dominance of HCS together with pedogenic carbonate (PC) is noted in semi-arid stages (MIS 4 and 2).

Soils of the Indo-Gangetic Plains: a pedogenic response to landscape stability, climatic variability and anthropogenic activity during the Holocene: Bound by the Himalaya in the north and the Craton in the south, the Indo-Gangetic Plains (IGP) is one of the largest fluvial plains of the world. The IGP is monotonously flatwith a spread of surface soils in hot arid conditions of Rajasthan in west to per-humid conditions in West Bengal. The soil-geomorphology of the IGP detailed during the last few decades is useful in determining the interrelationship among the pedogenesis, the climate, and the landscape evolution during the Holocene. These studies demonstrate that the IGP soils developed on five geomorphic surfaces with varying degree of development. Soils occurring on older geomorphic surfaces (N2.5 ka) are polygenetic with a distinct record of climatic changes and neotectonics. The present synthesis is based on recent developments in pedology achieved through macro- and micromorphology, clay mineralogy, pedogenic calcrete, and polygenetic pedogenic features of the IGP soils. A critical evaluation of the IGP soils has helped to comprehend the subtle nuances of the pedogenic processes that were also influenced by anthropogenic activities and cultivation over this vast agricultural tract during the Holocene. We provide state-of-the-art information on the pedology, polygenesis, and soil degradation (natural and anthropogenic) over the last 10 ka. The review has potential as a reference for critical assessment of the pedosphere for health and quality in different parts of theworld. In addition, it facilitates developing a suitable management practices for the food security in the 21st century.

A micromorphological record of contemporary and relict pedogenic processes in soils of the Indo-Gangetic Plains: implications for mineral weathering, provenance and climatic changes: Micromorphology has important application in earth surface process and landform studies particularly in alluvial settings such as the Indo-Gangetic Plains (IGP) with different geomorphic surfaces to identify climatic changes and neotectonic events and their influence on pedogenesis. The soils of the IGP extending from arid upland in the west to per humid deltaic plains

40

in the east developed on five geomorphic surfaces namely QIG1 to QIG5 originating during the last 13.5 ka. Four soil-geomorphic systems across the entire IGP are identified as: (i) the western Yamuna Plains/Uplands, (ii) the Yamuna-Ganga Interfluve, (iii) the Ganga-Ghaghara Interfluve, and (iv) the Deltaic Plains. Thin section analysis of the soils across the four soil-geomorphic systems provides a record of provenance, mineral weathering, pedogenic processes and polygenesis in IGP. The soils over major parts of the IGP dominantly contain muscovite and quartz and small fraction of highly altered feldspar derived from the Himalayas. However, soils in the western and eastern parts of the IGP contain large volumes of fresh to weakly altered plagioclase and smectitic clay derived from the Indian craton. The soils in western Yamuna Plains/Uplands dominated by QIG2–QIG3 geomorphic surfaces and pedogenic carbonate developed in semi-arid climate prior to 5 ka. However, soils of the central part of the IGP in the Yamuna-Ganga Interfluve and Ganga-Ghaghara Interfluve regions with dominance of QIG4–QIG5 surfaces are polygenetic due to climate change over the last 13.5 ka. The clay pedofeatures formed during earlier wet phase (13.5–11 ka) show degradation, loss of preferred orientation, speckled appearance in contrast with the later phase of wet climate (6.5–4 ka). The soils over the deltaic plains with dominance of vertic features along with clay pedofeatures suggest that illuviation of fine clay is an important pedogenic process even in soils with shrink-swell characteristics.

Mineral Formation in Soils and Sediments as Signatures of Climate Change: Soils and paleosols are one of the most important archives of the record of climate change. Identification of paleoclimatic signatures in paleosols forms the major challenge to the researchers. The soils/paleosols contain pedogenic minerals that formed as a result of environmental conditions and that are now altered. When environmental conditions and processes can be inferred using these pedogenic minerals, the story of climatic changes that led to the formation of these minerals can be interpreted with confidence. In this chapter, we describe the paleoclimatic potential of pedogenic minerals of soils and paleosols from different parts of India. The clay minerals of intermediate weathering stage have proved to be of great potential in parts of central India and the Gangetic Plains. For example interstratified smectite and kaolin (Sm/K) have showed the millennium scale climatic changes during the Holocene. In addition, clay minerals from western, southern, central and extra-Peninsular India indicate that pedogenic clay minerals like di- and trioctahedral smectites (DSm and TSm), smectite-kaolin interstratified minerals (Sm/K), hydroxy-interlayered Smectites (HIS), Vermiculites (HIV), pseudo-chlorite (PCh) of intermediate weathering stage and pedogenic carbonate (PC) and non-pedogenic carbonate (NPC) have helped to unravel the paleoclimatic record of the last 100 ka.

Red ferruginous soils of tropical Indian environments: A review of the pedogenic processes and its implications for edaphology: Red ferruginous (RF) soils of tropical Indian environments belong to Entisols, Inceptisols, Alfisols, Mollisols and Ultisols soil orders. The occurrence of Ultisols alongside acidic Alfisols and Mollisols in both zeolitic and nonzeolitic parent materials in humid tropical (HT) climatic environments, indicates that the soil diversity in India is

41

large. These soils are not confined to a single production systemand generally maintain a positive organic carbon (OC) balance without adding significantly to greenhouse gas emissions. This review presents a synthesis of literature on the recent developments on the pedology of RF soils, including their physical, chemical, biological, mineralogical and micro-morphological properties, and their degradation status. It also addresses the changes in soil properties in semi-arid tropical (SAT) areas, created by climate shift during the Holocene. This knowledge contributed to our understanding as to howthe parent material composition influences the formation of Alfisols, Mollisols and Ultisols inweathering environments of HT climate; and also as to howthe relict Alfisols of SAT areas are polygenetic. The state-of-the-art information developed through the extensivework on such soils has helped establish an organic link between pedogenetic processes and bulk soil properties, and has provided an insight of many pedological and edaphological issues related to Alfisols, Mollisols and Ultisols mainly of HT climate. The synthesis has helped us to understand as to why the formation of Oxisols from Ultisols is an improbable genetic pathway in tropical environment of India and elsewhere in the world. There is a strong need to modify the mineralogy class of highlyweathered RF soils. We hope this review will help to dispel some of the myths on the formation of tropical soils and their low fertility by putting in context their characteristics and capacity to be productive.

The recent discoveries of Late Cretaceous eutherian mammals from the Deccan Volcanic Province of India and rigorous phylogenetic analysis of these mammals demonstrated that these enigmatic mammals had given rise to adapisoriculids, a group of tree-dwelling mammals known from the Early Palaeocene rocks of Europe and Late Palaeocene of northwest Africa (Morocco). This demonstrated that India was a possible centre of origin for this group of mammals during its northward drift and these mammals had later dispersed to Africa and Europe. It further implies that the adapisoriculid mammals had survived the Cretaceous-Tertiary boundary (KTB) mass extinction event and lived for about 10 million years after the KTB biotic event. The latest findings raises the question as to how these mammals migrated from India to Africa and Europe across thousands of kilometers of open ocean as India was an island landmass in the Late Cretaceous. (published in Proceedings of the National Academy of Sciences of the United States of Americadoi:10.1073 /pnas.1108723108).

The extensive work on the Deccan intertrappean biota has shown that the initial volcanic activity has little effect on contemporary biota and the extinction of dinosaurs in the Indian subcontinent was independent of initiation of Deccan volcanism or bolide impact at least in the Indian context. (published in the Geological Society of America Special Publication, 2014).

Microvertebrate palaeontological studies on the Jurassic Kota Formation has unearthed many mammalian groups, such as symmetrodonts, morganucodontids, docodonts, multituberculates, and peramurids, previously documented only from the Jurassic rocks of Northern Hemisphere continents. Discovery of these rare mammals with South African, NW African and European affinities from the Jurassic of India has shown that Mesozoic mammals of India are much diversified than originally

43

thought and close biogeographic links were maintained with Africa and Eurasia in the Jurassic. (published in Naturwissenschaften 100:515-523).

So far, the continental Upper Cretaceous vertebrate fauna is mainly known from the Deccan intertrappean beds of peninsular India. Our recent field work in the Cauvery basin in South India has revealed the presence of a few microvertebrate yielding sites in the Upper Cretaceous (Maastrichtian) Kallamedu Formation exposed near the village Kallamedu, Ariyalur District, Tamil Nadu. Field prospecting of Kallamedu outcrops resulted in the recovery of abelisaurid dinosaur remains, sauropod post-cranial bones, crocodilian, turtle, amphibian and fish remains. The crocodilian remains belonging to the Gondwanan family Notosuchidae are remarkably similar to those of Simosuchus clarkiknown from the Upper Cretaceous (Masastrichtian) Maevarano Formation of Madagascar. Similarly, the dinosaur teeth from this formation are comparable to those of Cretaceous carnivorous abelisaurid dinosaurs of the former Gondwanaland such as Masjungasaurus crenatissimus of Madagascar. The common occurrence of simosuchid crocodile and abelisaurid dinosaurs in the Late Cretaceous of India and Madagascar implies that there was a biogeographic connection between India and Madagascar in the Late Cretaceous, at a time when these landmasses were separated by about 400 km wide marine body of water. Besides these finds, a troodontid theropod dinosaur tooth has also been recovered from the screen-washed residue. The troodontid dinosaur report is highly significant from the palaeobiogeographic point of view as this group of dinosaurs was restricted to the Laurasian landmasses (Published in (published in Journal of Vertebrate Paleontology 33(6): 1260-1268).

K/T boundary:

A unique, continuous shallow marine 10 m thick succession within the Langpar Formation in the Um Sohryngkew river section of Meghalaya, containing late Maastrichtian through early Danian planktonic foraminiferal zones e CF4, CF3, CF2, CF1, P0, Pa and P1a and the K/Pg boundary (between CF1 and P0) has been re-studied for clay mineralogy to understand the palaeoenvironmental conditions prevalent in the region and to assess the K/Pg transition. The relative abundances of the clay mineral phases permitted a threefold sub-division of the studied section with a illite, illite/ smectite dominated lower part, illite, kaolinite and abundance of montmorillonite dominated middle part and kaolinite/montmorillonite dominated upper part. Enriched HREEs in the lower part of the succession suggest variations in the pH of alteration solutions. Most of the samples show positive cerium (δCe) and europium (δEu) anomalies, the former reflecting oxidizing conditions at the time of clay formation. Illite dominated clays present a positive Eu anomaly, formed at relatively higher temperatures than the clays with less illite and without Eu anomalies, whereas clays occurring in the lower and upper parts exhibit a prominent negative Eu anomaly. Shifts in the redox condition found in this section are more or less similar to the foraminiferal changes and Au, Pt, Pd anomalies. Clay

mineralogical attributes and REE patterns, comparable to those of the known K/Pg boundaries, appeared within the CF3 and CF2 zones in the Um Sohryngkew river section. The sample at the boundary between CF3 and CF2 is marked by a negative δCe anomaly, high La/Yb and TOC values, suggesting that sea level rise during the upper part of CF3 was caused by tectonism rather than warming. The similar characteristics of clay minerals and REE patterns, attributed to the initiation of tectonic events during the CF3 zone, indicate environmental changes that affected the shelf area and the provenance of these sediments.

Physils divide entire succession into lower, middle and upper sub-divisions and represent anomalous values of redox-sensitive elements (Ce, La/Yb and Gd/Yb) in biozone CF3.Organicmatter when analyzed show TOC and C spikes in biozone CF3. Illite thermometry also revealed sudden increase in the palaeo-temperature (>140 ◦C) for yellowish brown 1–2 mm thick organic rich clay layer in biozone CF3. Conspicuous increase in the short chain n-alkanes and fatty acids is observed in the biozone CF3, although, longc hain n-alkanes (C27–C33) derived from terrestrial plants show low abundance throughout the succession. High amount of combustion derived fluoranthene, pyrene, chrysene, benzo(a)anthracene PAH compounds found in the biozone CF3 are analogous to those reported from the K/T boundary sections of Stevns Klint, Gubbio,Woodside Creekand Arroyoel Mimbral. The pyrolitic signatures of these organicmacro-molecules reflect global fire, caused distress to biota(during the deposition of biozone CF3 layer) which is coincidental with the well documented Ce anomaly layer, but, preceded by planktonic foraminiferal change in biozone P0 and PGE anomaly bearing layer in the biozone CF2.These organic macro-molecules reflect global fire, induced by the heat supplied by the late Cretaceous Abor and/or Deccan extrusions perhaps linked with the K/T transition events as later initiated prior to the K/Pg boundary, however, the main episode of Deccan volcanic activity occurred∼300 ky earlier or at the K/Pg boundary itself. The deposition of 1–2mm thick, yellowish brown, smooth(with conchoidal fracture) pyrite nodules and micro-spherules bearing organic rich clay layer marked with the decrease in the carbonate content (2.43%) that lies at the contact between the silty mudstone and grey calcareous shale located in the biozone CF3 of this succession coincides with the first appearance of Pseudoguembelina hariaensis representing age of 66.83-65.45 Ma is also related to the India’s collision with the Eurasia and Burma and extrusion of Abor volcanic. These events also endorse succeeding events such as anomalous concentration of platinum group of elements and concentration of spherules during biozoneCF2, which are other end Cretaceous events before the advent of the K/Pg boundary.

The Sandhan Formation represents the terminal Cenozoic formation in Cenozoic succession of Kutch. It witnessed the final withdrawal of marine condition from the basin. The siliciclastic dominated succession of the formation is deposited in the shallow marine environments followed by fluvial environment. The detailed filed based sedimentology and stratigraphic analysis has been carried out along two major river sections namely Kankawati (type section) and Kharod River reveals that marine

45

part was deposited in tide affected shallow marine condition followed by wave dominated beach setting. This is followed by fluvial deposits of braided type. The detailed facies and architectural element analysis of fluvial system was carried out. The interpretation suggests the deposition was primarily controlled by siliciclastic supply vs. relative sea-level fluctuation along western margin. The data generated will be used to establish the sequence stratigraphic framework of the area and to correlate it with regional and global perspective.

The Disang and Barail Group of Manipur and Nagaland are clastic sequence and flysch deposits. The basic analysis of Disang and Barail Groups were carried out to understand the stratigraphy and depositional environments. The Barail Group typically shows the thick alternations of sand and shale units with progressive decreases of shale percentage from Lisong to Ranji Formation and indicates slow and steady shallowing of the basin. The detailed sedimentological and stratigraphic analysis is requisite to suggest the depositional environments and paleobathymetric conditions.

The understanding of coupling between near-surface processes as represented by the development of sedimentary basins and related deeper crustal processes e.g. orogenic events, superplume generation etc. in the Precambrian era is problematic mostly because of lack of geochronological data related to the shallow near-surface processes. In the period under review the sedimentology lab of Department remained involved in establishinglinkage between age of near-surface processes in Precambrian continental blocks of India and correlating them with local/global well-established events and processes operative in the deeper continental crust/ its underlying mantle in the Proterozoic time. As one of the oldest continental blocks, Precambrian India poses unique opportunity to study all these processes in tandem. The Bastar craton in eastern India hosts several large to small sedimentary basins viz. Chhattisgarh basin, Ampani basin, Khariar basin and Singhora basin those share margin with one of the most long-standing Proterozoic mobile belt of India i.e the Eastern Ghat Mobile Belt (EGMB). New geochronological data are generated from bedded porcellinitic tuff layers occurring in Ampani, Khariar and Singhora basins and compared them with previous data of similar tuffaceous beds from two more northern basins. From generated data base it is inferred that a major felsic volcanic event occurred during ~1450 Ma in the eastern margin of the Indian craton. Detailed geochemical data of all these siliceous tuff units of geographically separated basins allowed correlation of these basins on regional scale and also to trace the erstwhile tectonic setting of the region. The geochronological and geochemical data of all these tuffaceous units allowed us to search for the contemporaneous events occurring at different levels of the Indian continental crust and its erstwhile neighbors in Precambrian supercontinents of “Columbia” and “Rodinia”.

A compartmentalized sedimentation model is proposed for the Mesoproterozoic Chhattisgarh basin including both in its early and very late depositional history; while initial sedimentation is registered only in the east in the

46

form of the Singhora Group, the Kharsiya Group represents the final stage with varying depositional character between the east (transgressive) and west (regressive and desiccative) of the basin. Besides, i) a wide variety of MISS structures described for the first time from the Chhattisgarh sediment successions ii) A detail sequence stratigraphic appraisal was carried out for the Chhattisgarh sediment package, iii) a model for glauconitisation, which is atypical for Precambrian time, is given from the Bhalukona Formation of the Chhattisgarh Supergroup.

Further, in the time period under review studies was also extended to the largest Proterozoic basin of India i.e the Vindhyan basin. Aim was to understand the Mesoproterozoic hydrosphere condition, which may be atypical in the entire earth history. All argillaceous intervals of the Vindhyan Supergroup were studied in terms of field sedimentology, geochemistry and evaluation of their hydrocarbon potential. From low concentration of molybdenum (Mo) and Mo/TOC ratios in Vindhyan shales, it is inferred that the Vindhyan was a stratified sea with sulphidic, reduced deep water and oxygenated surface water as recorded globally from marine successions of concerned time period. That the basin became uniformly circulated during the Sirbu time including oxygenation of its deep water is evident from ~3‰ enrichment in 13δCorg value in organic matter from the Sirbu Shale.

Detail shale Formation- specific Total Organic Carbon (TOC) analyses revealed high (>2 % up to 8 %) values within Arangi and Bijaygarh Shales. Other shale units record values <1% except some samples from the Rewa Shale those record values >1%. Further, C-H-S analysis and Rock-Eval pyrolysis were carried out on organic matters from different shale units to assess their potential as hydrocarbon source. Results suggest Vindhyan organic matters as Type-III (humic) in character with high carbon (C) and very low to negligible hydrogen (H) contents and hence, gas-prone and mostly under- or over-matured, except for the Arangi and Bijaygarh Shales those besides yielding high TOC values also show 'matured' stage of organic matter.

Palynology and clay mineralogy of the Deccan volcanic associated sediments of Saurashtra, Gujarat: Age and paleoenvironments: The intertrappean sediments associated with Deccan Continental Flood Basalt (DCFB) sequence at Ninama in Saurashtra, Gujarat yielded palynoassemblage comprising at least 12 genera and 14 species including Paleocene taxa such as Intrareticulites brevis, Neocouperipollis spp., Striacolporites striatus, Retitricolpites crassimarginatus and Rhombipollis sp. The lava flows of Saurashtra represent the northwestern most DCFB sequence in India. It is considered that the Saurashtra lava flows represent the earliest volcanic activity in the Late Cretaceous of the Reunion Mantle Plume on the northward migrating Indian Plate. The present finding of the Paleocene palynoflora from Ninama sediments indicate Paleocene age for the associated lava flows occurring above the intertrappean bed which suggests that the Saurashtra plateau witnessed eruption of Deccan lava flows even during Paleocene. The clay mineral investigation of the Ninama sediments which are carbonate dominated shows dominance of low

47

charge smectite (LCS) along with the presence of mica and vermiculite. Based on the clay mineral assemblage it is interpreted that arid climatic conditions prevailed during the sedimentation. The smectite dominance recorded within these sediments is in agreement with global record of smectite peak close to the Maastrichtian–Paleocene transition and climatic aridity.

Early Oligocene paleosols of the Dagshai Formation, India: A record of the oldest tropical weathering in the Himalayan foreland: This study reports paleopedological features of the fossil soils that formed during the earliest phase of continental sedimentation in the Himalayan foreland. The fluvial sequence of the Dagshai Formation (31.6 ± 3.9 Ma to 30.3 ± 3.9 Ma) exposed along the Koshaliya River, NW Himalaya, contains four pedofacies (named Pedofacies A–D) of ferruginous paleosol sequences contained within overbank sediments. The Dagshai Formation unconformably overlies the marine Subathu Formation. Pedofacies A consists of 3–4 well-developed ferruginous paleosols overlain by gray sandstone beds. Pedofacies B–D are marked by a progressive decrease in pedogenesis. These paleosols occur as 0.5 m to 1.5 m thick Bw/Bt/Btk/Bk/Bss horizons that are marked by extensive development of rhizoliths, pedogenic carbonate, and iron-rich clay pedofeatures that correspond to modern Entisols, Inceptisols, Alfisols and Vertisols. Based on early Oligocene paleogeographic position of the northward-drifting Indian Plate, it is inferred that these paleosols were formed at ~18°N paleolatitude in the Dagshai sub-basin in the Himalayan foreland. Micromorphology, geochemical analyses, weathering indices, and stable isotope composition of paleosols indicate tropical climate (paleoprecipitation of 947–1256 mm and paleotemperature of ~25 °C) with an initial phase of monsoonal conditions during pedogenesis. These paleoclimatic conditions favored C3 paleovegetation immediately after the transition from greenhouse to icehouse conditions.

Thin-section analysis of lithified paleosols from Dagshai Formation of the Himalayan Foreland: Identification of paleopedogenic features and diagenetic overprinting and implications for paleoenvironmental reconstruction: In the present study we report micromorphology of diagenetically altered paleosols (~31 Ma old) from Dagshai Formation, Himalayan Foreland. The fluvial sequence exposed along the Koshaliya River, NW Himalaya, contains four types of paleosols with decreasing abundance of well-developed paleosols from basal to upper part of the Dagshai Formation. Burial diagenesis (at ~7.5 kmdepth) caused compaction (54–78% current thickness compared to pre-burial thickness) and cementation of the paleosols, accompanied by internal reorganization of groundmass within peds, staining of pedwallswith iron oxide, plugging of voids, disruption of textural pedofeatures, fracturing of large mineral grains and nodules, coarsening of pedogenic calcite crystals, redoximorphic features, and mineralization of root channels. Despite diagenetic alteration, evidence of paleopedogenic processes is still well-preserved in these fossil soils in the form of microstructures, b-fabrics, pedogenic calcite, bioturbation,and textural pedofeatures. Thin-section analysis helped to distinguish pedogenic and diagenetic features of lithified paleosols and to infer the paleoenvironment of the Dagshai paleosols. The paleopedological characteristics of the fossil soils suggest humid to sub-humid conditions during their formation in early

48

Oligocene. The paleoclimate inferred here is consistent with prevalence of tropical paleovegetation (cf. Ficus L.) reported from Dagshai sediments.

Proposal-1: Microstructural and experimental modelling of faults

In the next phase of CAS, I intend to expand the existing analog experimental

facility and strengthen its infrastructure. Air-conditioning and flooring of the

experimental laboratory was not possible from the last CAS budget and these things

are necessary right now for technical advancement of the laboratory. There is a plan

to build a shaking table-type apparatus where we shall be able to experiment with

water-sogged soil and sediments under rapid vertical and horizontal shaking, to

understand the types of seismogenic soft sediment structures (water injection dykes,

seismites etc.) and their relationship with the type of movement. The experimental

observations can be correlated with the observed seismic structures of Gavilgarh

Fault zone and the Son-Narmada South Fault in central India where a Ph.D. student

is already working. Results of such earthquake-related experimental studies, yet to be

taken up in India, have great societal relevance.

Apart from experimental work, I would like to start a new facility for fabric

analysis in structural geology. Fabric analysis of deformed rocks essentially needs a

characterization of the deformed lattice of minerals. Lattice –preferred orientations of

minerals can give fundamental information on temperature and strain rate, as

different glide planes are sequentially activated with increased temperature and strain

rate. Analysis of LPO is done nowadays using Electron Back-Scatter Diffraction

(EBSD) facility fitted with a Scanning Electron Microscope. As the Department of

49

Geology already has an SEM in fully working condition, we should try to upgrade it

with an EBSD facility.

Funds are required for field work in Central Indian Tectonic Zone, especially

for post-Cretaceous tectonic movements in Gavilgarh Fault, Son-Narmada South

fault and Son-Narmada North Fault which have controlled the entire landscape

evolution of central Indian craton since Precambrian time. I would also need funds

for chemical analyses on payment from outside agencies (e.g. EPMA from GSI,

ICPMS from NGRI/WIHG, OSL data of river sediments from PRL/WIHG etc.).

Proposal 2: Constraining the age of formation of the crustal sequence of the

Andaman island Ophiolite suite to understand intiation of subduction along

Java-Sumatra-Andaman-Burma trench system.

Rationale: In the ophiolite suite of the Andaman Island, all the members of a classic

ophiolite sequence namely the plutonic complex, intrusive, extrusive lava series and

pelagic sediments except the sheeted dyke are well exhibited.

A two-fold subdivision of the ophiolite suite have been forwarded by previous

workers namely a mantle sequence represented by serpentinised harzburgite and pods

of altered dunite and the overlying crustal sequence marked by an assemblage of

plutonic rocks and extrusives. The plutonics of the crustal section is mainly layered

cumulates of peridotite –gabbro, overlain by non cumulate gabbro and high level

intrusive of a Plagio-granite-diorite-andesite suite of rocks with thin dykes of basalt

and diabase. Overlying the dyke complex is the pillowed and non pillowed lavas

representing the upper most part of the ophiolite suite.

Two models have been proposed for occurrence of this ophiolite suite. One school of

thought proposes that the subduction has continued along the western margin of the

island arc since the late Mesozoic and the Andaman ophiolite suite is the upthrust

oceanic crust accreted during the prolonged period of subduction (Pal et al. 2003;

Curray 2005).The alternative idea suggests this suite ranges in age between Late

Mesozoic and Early Eocene and were tectonically emplaced at the leading edge of

the Eurasian continent during middle Eocene to Late Oligocene event, before

Andaman–Java Subduction which probably initiated during the late Miocene

(Sengupta et al. 1990; Acharya 2007).

No radiometric age data has been reported for these ophiolites except for two recent

works. U-Pb SHRIMP age of Zircon from Plagiogranite has yielded an age of 93.6 +

1.3 Ma, interpreted as the age of its crystallization. Since the Andaman ophiolitic

50

rocks predate the palgiogranite they were probably not generated in the currently

active Late-Miocene Andaman-Java subduction zone and were obducted onto the

leading edge of the Eurasian continent during early Cretaceous time (Sarma et al.,

2010). U-Pb zircon dating of a trondhjemitic rock from Chriya tapu in south

Andaman Island using Laser ablation inductively coupled mass spectrometery reveals

an age of crustal formation of 95+ 2 Ma (Pedersen et al., 2010). This data shows that

the Andaman volcanic arc was built on Cenomanian ophiolite-oceanic crust and

subduction was initiated at this time along Tethys. Other than this paleontological

data from oceanic sediments closely associated with ophiolites have revealed an

Upper cretaceous to Early Eocene ages for these ophiolites. However, no work has

reported age dates from basalts, rhyolites, dacites and ultramfic rock units of the

Andaman ophiolites.

So far the tectonic evolution of the Andaman island have been modeled based on the

tectonic elements recorded from the sea, seismic records and regional tectonic

correlation with eastern Himalayas and no tectonic model has been built based on the

petrochemistry and geochronology of the rocks from this suite.

The petrological and geochemical characteristics of the magmatic rocks of the

ophiolite suite are poorly constrained. Significant insights can be gained on the

tectonic environment at the time of the primary magmatic evolution through

geochemical characterization. A concerted age dating of this sequence of rock both by

isotopic dating will place its position precisely in the geological scale.

The proposed research has been conceived with an idea to ultimately reconstruct the

events through time leading to formation of these magmatic rocks and emplacement

by tectonic movements into continental setting to throw light on the geodynamic

evolution of the Indian sub-continent.

Objective of the proposed study

The proposed study aims at addressing the geodynamic evolution of the Andaman

Island Ophiolite suite based on geochemical and geochronological constraint.

Significant insights can be gained on the tectonic setting at the time of formation of

these rocks based on geochemical and geochronological data and also how the Indian

sub continent has evolved to the present day configuration wherein, this ophiolite

suite probably marks the eastern suture margin of Indian plate.

Proposal 3: Geochemical Flow Stratigraphy, Age and Duration of Deccan Volcano-Sedimentary Succession from Koyna Drill-Core Site

51

Recently drilled Koyna Bore Hole - 1 (KBH-1), located at Rasati [Survey of India Topographic sheet No. 47 G/11 and 47 G/15 (scale 1:50,000)] near Koyna (~2.5 km SSW of Koyna Dam reservoir region) is unique of its kind and represents to a deepest bore hole that extends up to the base of the Deccan Traps, however, such details are yet to be ascertained (Fig. 1). These longest drill core samples available provide unique opportunity to study sub-surface lava flow sequences flow by flow. Therefore, such a thick basaltic package is required to be constrained in to a stratigraphic framework. However, such studies have not been carried out on Koyana dill core samples. Lateral continuity of lava flows is critical for constructing a stratigraphic framework. Systematic litho-logical logging backed by detailed petrography of core specimens would be undertaken in the recognition of physically distinct lava flows and their flow boundaries. Koyna revealed a ~933 m thick pile of basaltic flows, underlain by granitic basement rocks. It is necessary to find out geochemical and isotopic characters of the ~933 m thick pile of Koyana basalt lava flows and at the same time it is also necessary to understand chemical correspondence of these lava flows with that of the 11 southwestern Deccan formations of the type-sections. To establish nature of geochemistry and Ar/Ar ages of the first lava flow and the clay-stratigraphy of the intervening intratrappen and bole sediments to find out possible level of the K/T boundary is also required. To understand the lateral continuity of lava flows and to characterize them into distinct chemical types, chemical signatures of the sampled flows are required to be examined. Presence of distinctive lava flows in the ~933 m thick lava package requires justification from the major and trace elemental chemistry. Present project proposal intends to study drill cores of the entire Deccan volcanic pile. It seems drill cores are the only possible way to make significant progress on further understanding of the Deccan Traps and its possible relationship with the K/T boundary event. The proposed stratigraphic studies, primarily based on the trace elemental abundances, their ratios and isotopic compositions constitute major component and would be undertaken in this project proposal.

Project 4: Geological investigations south of Indian Bharati Station to elucidate sub-ice geology and to establish the affinity of western Princes Elizabeth Land (PEL) with appropriate cratonic block

Our knowledge of East Antarctica continues to be ill-defined in spite of vigorous research programs conducted in this area from last two decades. This lack of knowledge not only sets a hurdle in understanding the subice geology but lack of this knowledge has a role in understanding the role of East Antarctica in the global environment now, in the past, and in the future as ice-sheet behaviour is also controlled by the geological parameters of the interaction surface.

Princess Elizabeth Land (PEL) comes under ‘poles of ignorance’ category of EAIS. It is located inland of the Chinese Zhongshan Research Station and the Indian Bharati Station. We possess a very shallow knowledge about the subsurface ice sheet, and the crust on which it flows, across PEL in East Antarctica. PEL is the focus of this proposal. The BEDMAP2 depiction of topography over PEL, used as input to ice

52

sheet models, is based on ~100 seismic measurements acquired by Russian overland traverses in the 1950s and 1960s. Specifically, there are few bed data west of 105⁰E and no data west of 90⁰E in the PEL region, making it the last remaining frontier of Antarctic glaciological science.

These glaciological and geological data gaps can be filled through airborne geophysical profiling and correlation with rock exposures. The collection of geophysical data is planned in a major international initiative in the next two years. However, the validation of such a data requires detailed analyses of available rock exposures through ground survey. A detailed sampling thus becomes essential in this endeavour.

Recently Boger (2011) divided the Antarctic continent into 4 main categories on the basis of their affinities with Antarctica's correlatives within Gondwana. PEL lies in the area marked by category 4 (i.e., the rocks with no known affinities). Its proximity to the category-2 rocks (i.e., the rocks with Indian affinities) also requires examination. Moreover, the knowledge on its spatio-temporal evolution is either very limited or ill-defined.

A detailed geological study of this area can provide us with valuable data which would further enhance our understanding on the amalgamation of the present day Antarctica as well as its interrelationship with the Indian Craton. Participation of an Indian expedition will bring these efforts in the current global scientific context. Moreover, it would facilitate our knowledge about supercontinent cycle over the geological time and the role of Antarctic continent in it.

Hypothesis to be tested is the following;

Queen Maud Land Province which is present NE to PEL shows affinity towards Indian Craton while Wilkes Land present SSE of PEL have rocks with Australian affinity. However, there is no correlation of PEL terrain rocks with the Indian Cratonic Block till date. Extensive studies are required in PEL to infer the affinity of this region between the Indian and the Australian cratonic blocks.

Methods adopted are following:

Detailed field survey around PEL and collection of hard rock samples from the exposed lithologies.

Detailed petrological analysis of the samples collected, including reflected as well as transmitted light microscopy. Analysing the microfabric to infer evolutionary track of the rocks

Appropriate geochemical data will be generated to understand the geodynamics and tectonic history of PEL.

Chronology of the samples will be carried out by chemical dating of monazite grains as well as radioactive dating techniques of other suitable minerals.

Development of a petrogenetic model for the defined area.

First field investigation in and around Bharati Station has already been carried out during Antarctic field season 2015-16 recently by one Ph.D. student (Ms Devsamridhi) as a member of 35th Indian Scientific Expedition to Antarctica. This will be continued in field season 2016-17 and the data will be integrated with the multinational project ICECAP-2 (International Collaborative Exploration of Central

53

East Antarctica through Airborne geophysical Profiling) of which the undersigned is a Steering Committee member.

Proposal 4: Investigations on hydrothermal ore deposits in parts of the Indian subcontinent

In the coming years, department aims to adopt a dual approach in context of metallogenic

studies. On the one hand, it involves ore genetic studies to tie-up the records of

metallogeny with that of crustal evolution in parts of the subcontinent. On the other hand,

we aspire to upgrade the existing laboratory facilities for research on ore fluids.

The field-based studies will emphasize on genesis of hydrothermal ore deposits in various

parts of the country. From gold metallogeny point of view, the amphibolite-granulite

transition zone in south India is one of the targeted regions. The key issue is decoding the

links between lower crustal evolution and mid-crustal gold-enrichment processes.

Besides, we anticipate the refinement of ideas on ore-forming processes in parts of the

Aravalli-Delhi belt in western India. In this regard, the metallogenic belts of Degana-

Tosham (W-Sn), Pur-Banera (Pb-Zn-Cu) and Khetri (Cu) would be the areas of prime

focus. In addition to this, up-gradation and maintenance of the existing fluid inclusion

set-up is under consideration. We desire to integrate the existing set-up with infrared

facilities. This will broaden the scope of ore genetic and interdisciplinary studies in the

department. With the aforesaid aims and plans, the department is perfectly positioned to

grow its impact in metallogenic studies.

Implementation of proposed plans demands a significant amount of laboratory-based

analytical data. The scanning electron microscopic and fluid inclusion facilities hosted in

the department would be used for the purpose. The whole rock, electron micro probe and

stable isotope analyses are to be carried out at various units of Geological Survey of India

and in some other overseas laboratories.

Proposal 1:Immobilization of radionuclide (ions) and its diffusion in natural glasses for its suitability as nuclear waste glass

54

The immobilization of radioactive components for long-term isolation from the biosphere depends upon the performance of the material used and these materials determine its safety and hazards. It is used to immobilize HLW for more than 40 years when treated with calcinations and vitrification processes. From the nuclear waste management point of view, the long-lived radionuclides which are of great concern include fission products (Cs 137, Cs137, Sr90, Tc99 and I129) and several actinides (Am 241, Am 243, Np237, Pu244, Pu 239).Purpose of nuclear waste management is to develop highly durable waste matrix that ensures long-term stability of material for isolation of its radioactivity and to provide physically, chemically and thermally stable form to immobilize radioactive materials that resist leaching, powdering and cracking mode of degradation. Thus, an appropriate performance assessment technique is required to utilize glass as a waste form for nuclear waste disposal that assumes an understanding of alteration or corrosion mechanism of the glass.High energy irradiations on glass surface with 40-50 keV is yet to be carried out in glasses especially natural glasses (Impact and Obsidian glasses) to understand diffusion of radionuclide. However, these glasses were not studied in context with the Cs, Sr and other long-lived radionuclides. Previous work (Ceelen et al., 1995 and Tomar et al., 2005) on Cs diffusion was out carried, primarily based on depletion of ions at lesser depth. However, Cs, Sr and long lived radionuclide irradiation/ implantation on natural and synthetic nuclear waste glasses and their alteration studies in a geological repository is yet to be carried out.Main objectives to immobilize ions natural glasses for its diffusion study in hydrothermal-like conditions. To quantifythe release of immobilize ions (radionuclide) from the natural glasses for its suitability as nuclear waste containment. To compare the alteration of natural glass in natural environment with that of the natural glass treated in hydrothermal-like conditions in laboratory frame work.

Proposal 2:Geochemical modelling and CO2-basalt reactivity on Deccan basalt”

Deccan basalt in India, offers storage deport for carbon dioxide as they contain iron magnesium and calcium silicate minerals. Objective of the proposal is to understand mineral carbonation reactions under hydrothermal-like conditions.Such studies requirequantification ofcarbon-dioxide pressure, temperature and time at variable ratios of surface area and volume of grains, porosity and permeability. Laboratory scale experiments on crushed samples carried out in Delhi University necessitate their confirmation from bulk carbon dioxide-basalt reactivity for which whole core reactionexperiments will be carried out in the laboratory set-up available in Delhi University. Correlation of results is essential for the assessment of degree of immobilization of carbon dioxide in Deccan basalt.

Proposal3: Fingerprinting of glacial melt water in the Ganga Basin- implications for modelling of hydrological cycle in a Himalayan River System

The Himalayan glaciers form the largest body of ice outside the Polar Regions and it forms the unique reservoirs of fresh water. There are nearly 10,000 glaciers in Indian Himalayas. The variability in the hydrological cycle of the Himalayan river system can be modeled properly by calculating the contribution of multiple sources properly. Hydrological field data from these regions is sparse.

Gangotri glacier which is one of the largest glacier in Himalayan region and it also records highest recession rates in this region. The work aims to build glacial melt-

55

water component in the Bhagirathi River within the Bhagirathi basin from the snout of the Gangotri glacier to the confluence of the Bhagirathi River with Alaknanda River. Mapping of geomorphological elements in the glacial and periglacial domains around the Gangotri glacier to correlate the recent past variability of this glacier is also proposed to be a component of the work. The discharge of Bhagirathi River shows positive correlation with temperature and negative correlation with the rain event. The outcome of the project is expected to lead to basic input for modeling the glacial melt-river discharge quantitative estimation for the Himalayan glacier.

The project aims at progressing more than one independent fronts with the aim of emerging with a comprehensive model of Gangotri glacier variability in recent past and prognosticating about projected behavior in future. This entails generation of multiparametric data of the following type;

1. Hydrograph separation of the glacial melt water and water from other sources in the Bhagirathi River from Gomukh to Rudraprayag.

2. Mapping of geomorphological elements in the glacial and peri-glacial domains around the Gangotri glacier to correlate the recent past variability of this glacier

Proposal 4: Simulation of groundwater flow dynamics and assessment water quality variation in parts of Indo-Gangetic basin, India.

Introduction:

Indo-Gangetic basin has voluminous non indurated sediments giving rise to

heterogeneous aquifer system. This is one of the most important alluvial aquifer system;

sustaining the water requirements of a huge population. It has in past decades supported

rapid developments in agricultural and industrial sectors. Linked with this, there has been

rapid urbanization in the basin. The basin has served the need for providing food security

to country through implementation of Green revolution. It also has many major industrial

townships. Under natural condition the groundwater flow dynamics in the basin

approximates topography. However anthropogenic forcing often changes the flow

56

dynamics on local scales. It could be possible that at times there is significant change in

the flow dynamics. Besides the abstraction often exceeds the resilience limit of the

groundwater system. Thus it requires defining thresholds of the system at local and

regional scale. This can be attempted by simulating groundwater flow at predefined scale

based on the present stress pattern.

With regards to groundwater quality, the river basin in normal circumstances is

expected to have fairly defined hydrochemical facies in recharge and discharge areas.

However, in the course of developmental activities, very often the contributions from

geogenic sources of groundwater pollution are accelerated, leading to changes in

groundwater chemistry. This is manifested by hydrochemical facies observed in the

groundwater and anomalous concentration of contaminants. The problems become acute

when the anthropogenic contamination sources like drains, polluted rivers, and landfill

sites become prominent. It is endeavoured to establish a picture of linkages between trace

element concentration in groundwater, contamination, hydrochemical facies variation and

groundwater flow dynamics.

Objectives:

The projects aims to simulate groundwater flow dynamics and foresee the aquifer

response to possible changes in stress on the groundwater system. The resilience of the

groundwater system to present stress would be examined and thresholds identified. The

changes in chemical character of the groundwater system at local and if possible at

regional scale in the Indo-Gangetic basin would also be assessed. A possible linkage

between trace element concentration in groundwater, contamination, hydrochemical

facies variation and groundwater flow dynamics would be established.

Work plan and methodology:

1. Preparation of Land-use, geomorphic, hydrogeological and geological maps for the study area.

2. Assessment of aquifer geometry and identification of its simplified proxy for groundwater

system simulation.

3. Conceptual generic groundwater models.

4. Simulation of groundwater flow dynamics.

5. Calibration and validation of the groundwater flow models.

6. Assessment of aquifer response to possible changes in stress on the system.

7. Analysis of Total Hardness, E.C. pH, TDS, Total alkalinity, major cations

(Na+,K+,Ca2+,Mg2+,Fe2+/Fe3+ etc.), major anions (Cl-,NO32-,SO4

2-,CO32-HCO3

- etc.) and Trace

elements of groundwater, river water, drain water etc. from different locations at regular

interval of time (3 or 6 months) for at least two to three year.

57

8. Analysis of geochemistry of alluvial sediments corresponding to distinct hydrochemistry of

groundwater in the study area.

9. Preparation of Geochemical datasets for groundwater, surface water, sediments etc. And

interpretation of the result.

10. Assessment of hydrochemical facies, linkage of contamination in groundwater with land-

use, sediment geochemistry, anthropogenic sources, groundwater flow dynamics etc.

The project is proposed to be completed by engaging Ph.D. students with the twin

objective of achieving the desired objective of completing the project in specified time

and at the same time helping the PhD student in the research problem which will also

lead to time bound completion of his PhD Thesis. Some M.Phil and M.Sc. dissertation

students may also be involved in smaller segments of the study area.

Expected outcome:

The projects will simulate the groundwater flow dynamics and assess the

changes in chemical character of the groundwater system in the syudy area. The

information can be used for decision support related to development paradigms

in the present agrarian economy. It will help in demarcating groundwater

potential zones, hydrochemical zones etc. in the study area. Proposals for

mitigation and prevention of groundwater contamination will be formulated. The

recommendations will ultimately help state governments, city planners and other

stake holders in formulating sustainable groundwater development and

management strategies.

Proposal 1a: Indian Monsoon variability during the Quaternary and its relationship with the various parameters like Inter Tropical Convergence Zone, El Nino and Indian Ocean Dipole.

Proposal 1b: Paleoceanographic changes during Late Neogene and The Quaternary and also work on the causative factors as well as their effect on global climatic condition

Objectives of the proposed project under CAS program:The main objectives of the proposed work are as follows

i. To document the changes in surface water hydrography based on Planktic foraminiferal population variations as a result of changing strength of Indian Monsoon during The Quaternary (by studying samples at very close spacing).

ii. Further to understand underlying causative factors including probable teleconnections between Western pacific warm Pool, El Nino, southern oscillation and Indian Monsoon. This would be accomplished by generating high resolution Planktic foraminiferal abundance data base and stable isotopic records (Oxygen and Carbon isotope records) for providing time frame work against which the oceanographic and climatic changes occur.

iii.To check the Influence of ENSO on the development of WPWP and also on the strength of ITF by documenting the change in the population of water mass sensitive Planktic foraminiferal studies from the western Pacific sites (Both census count and stable isotopic studies)

iv. To check the variability in the sea surface temperature variation due to ITF inputs in the Indian Ocean by stable isotopic studies of planktic foraminifera and also understands its effect on the Asian monsoon.

v. To check the strength of ITF on the Indian Ocean dipole (IOD) and its relationship with Asian monsoon.

vi. To document the sequential order of foraminiferal events at ODP site 846B during Late Neogene Quaternary to arrive at a high resolution Planktonic foraminiferal biostratigraphy ( at 30 cm interval).

vii. To compare and contrast the biostratigraphy with other ODP sites particularly from Western Pacific Warm Pool.

viii. To generate planktonic foraminiferal census data for inferring Paleoceanography. The data generated would consist of relative abundance of water mass sensitive planktonic foraminifera and depth stratified assemblages. This would reflect the changing thickness of mixed layer and depth of thermocline.

59

ix. To compare the Quaternary Paleoceanographic changes inferred at various ODP sites with each other which have oceanographic connectivity.

x. To understand the impact of closure of various gateways like Central American Seaway, Indonesian through flow on the planktonic foraminiferal assemblage at the different ODP sites.

Proposal 2: Diversity and biogeographic affinities of Jurassic mammals of India - Jurassic mammals are relatively rare from the Gondwanan continents as compared to the highly diversified assemblages from the Laurasian continents. In the Southern Hemisphere, they are known only from Tanzania in Africa, Argentina in South America and India. The existing fossil record shows that only triconodont, dryolestid, and haramiyid mammals are known from South America and Africa. In marked contrast, the Jurassic strata of India appear to contain more diversified fauna comprising several groups, such as symmetrodonts, morganucodontids, triconodonts, docodonts, and multituberculates, known from the Northern Hemisphere. We need to know why such a disparity exists in the mammalian faunal composition between the Gondwanan continents in order to better understand the evolution of Jurassic mammals in the southern continents. The main objective of the work is to know whether biogeographic partitioning of Gondwanan ecosystems existed in the Jurassic or not. The Jurassic Kota Formation (Pranhita-Godavari valley) and other Jurassic sequences of western India will be subjected to intensive vertebrate palaeontological studies to test this hypothesis.

Proposal 3: Evolution and biogeographic patterns of vertebrate fauna during the northward flight of India – Geophysical data has shown that India was rapidly drifting as an insolated landmass during the Cretaceous Period. Such a palaeogeographic scenario would lead to vicariant evolution of biota on the insolated landmass. The biogeographic affinities of Late Cretaceous (Maastrichtian) vertebrates from the Deccan volcanic province are fairly well understood. As compared to this, the early and middle Cretaceous vertebrate fossil record is poorly documented from India. Secondly, which biogeographic pattern (vicariance vs dispersal/geodispersal) was dominant during the entire time span of the Cretaceous Period is not known at present. To fill these gaps in our knowledge, the Cretaceous succession of Cauvery basin where strata representing nearly the entire Cretaceous Period are exposed and the Cretaceous succession of Narmada valley spanning Turonian to Coniacian will be made focus of the study.

Even in the well studied Deccan volcanic province, the mammalian fossil record is biased towards eutherian mammals. Until now, no marsupials, multituberculates and monotremes have been documented from the Late Cretaceous of India. It needs to be investigated whether the absence of these groups is an artifact of sampling bias or these groups did not inhabit the Indian subcontinent in the Late Cretaceous. As the mammalian fossils discovered from the Deccan volcanic province are the only known eutherian mammals from the Gondwanan continents, it becomes all the more important to know the diversity and distribution of Cretaceous mammals of India in the context of mammalian origins, dispersals and distribution. Therefore, focused

60

studies on vertebrate fauna of Deccan volcano-sedimentary sequences will be continued.

Proposal 4: Palaeogene vertebrate fauna from the western India – implications for India-Asia collision tectonics – In order to understand the mode of evolution and dispersal patterns of vertebrate fauna during the northward drift of India, a continuous fossil record representing the Cretaceous, Palaeocene and Eocene periods during which India made its journey to the north to dock with Asia is to be documented. Thevertebrate fossil record is fairly well documented from the Late Cretaceous and Early Eocene of India, but the Palaeocene record is very poor to non-existent. Late Palaeocene-Early Eocene is also the time during which lignite was deposited in many places in western India and in Pakistan. The tectonic and climatic conditions that led to the formation of these coal deposits on the western continental margin of India in the closing phases of Tethys is another issue that demands focused attention. Keeping these in view, an attempt will be made to study the Palaeocene-Eocene deposits of western Rajasthan from vertebrate palaeontological and palaeoenvironmental points of view.

Proposal 5: Clay-organomolecular studies on sediments of the late Cretaceous-early Paleocene succession of the Mahadeo-Cherapunji section to assess lateral continuity with the K/Pg layer of the Um-Sohryngkew river section, Meghalaya: palaeoenvironmental implications and K/Pg transition.

Shrivastava et al (2013) reported high abundance of rare earth elements, negative δCe anomaly, high La/Yb and Gd/Yb values together with the negative spike in the total carbon and positive spikes of total organic carbon (TOC) in the 1 - 2 mm thick, yellowish brownorganic rich clay layer which lie between silty mudstone (20-25 cm thick) and grey calcareous shale layer located in the biozone CF3. Significant increase in the kaolinite contents as well as layer and inter-layer charges in illites associated with the yellowish brown clay layer (sample JP-12) is compositionally similar to the clays associated with the well-established K/T boundary layers of Agost, Caravaca, Petriccio and El-Kef sections. These attributes of the yellowish brown clay layer together with the sudden increase in the temperature (>140ºC) perceived in the upper part of the biozone CF3 (sample JP-12) are analogous to the attributes of the clays associated with the K/T boundary layer of the Caravaca section. This layer is marked by spikes in the n-alkanes, n-fatty acids and high molecular PAH compounds. These positive and negative spikes found in biozone CF3 when translated in terms of time sequence, it has been found that these changes are possibly due to multiple K/T boundary transition events occurred in the late Maastrichtian period.

Fine resolution stratigraphy based on planktonic foraminiferal zonation revealed that this section is continuous across the boundary (Mukhopadhyay 2008) and qualifies as a potential candidate to study paleoenvironment during the K/Pg transition.However, lateral extension of 1 - 2 mm thick, yellowish brownorganic rich clay layer is required to be studied in details for better resolution as well as recognition of K/Pg boundary in this area. Therefore, Mahadeo-Cherrapunji road section is significant that necessitates detailed study in this context.Therefore, it is necessary to systematically record clay mineralogical variation and trace and Rare Earth Elemental (REE) concentrations together with Ce and Eu anomalies in the

61

K/Pg boundary section to understand palaeoenvironmental conditions prevalent during the end Cretaceous period. It is also necessary to explain the correspondence and disparity between the major anomaly of clay minerals and the K/ Pg boundary in terms of tectonics. Formation of organic macromolecular structure is complex; therefore, variation in the distribution of organic molecules if recorded systematically across the succession would unveil palaeoenvironmental variables accountable for their formation. Such studies are significant in this context; however, need to be carried out in this area.Mechanism of interaction between clay and organic compounds in K/T boundary associated sediments is yet to be understood. To resolve K/T boundary, study of gross macro-molecular carbon skeleton structure of heterogeneous geopolymers with special reference to its possible linkage with the clay component is necessary and study would unveil palaeoenvironmental constraints accountable for their origin.Correspondence and disparity in the clay-organic matter with the Um-Sohryngkev river section as well as with well-known K/Pg boundary sections across the world need to be studied.

Proposal 6: Bio-events and Compositional Studies on Clays and Organic Matter Associated with C-T and K-T Boundary Sequences of Tiruchirappalli: Palaeoenvironmental Inferences and K/Pg Transition

The Cretaceous succession in Tiruchirappalli region is one of the best-developed sedimentary sequences in the South India. The variability of clay mineral changes recorded at the Cretaceous / Tertiary boundary imply a unique modification of the environment, such as warming and cooling, extensive differential settling processes, or early diagenetic modifications of extra or intra - terrestrial materials. The clay minerals present in the K/TB layer are reflective of the chemical components operative / available at the time of their formation. All these changes have homogeneous and synchronous trend in clay mineral successions.Biological organic compounds in the K/T boundary sediments provide useful information on the mass extinction as they were derived from the then living organisms (Mita and Shimoyama, 1999). In this scenario,compositional studies on organic matter extracted from the intercalated mixed layer clay complexes of Cenomanian-Turonian (C-T) and Maastrichtian-Danian (K-T) boundary sequence of Tiruchirappalli is required to be undertaken in details. Present project proposal is designed to study the nature and type of the organic macromolecules, plausibly associated with the smectite or mixed layer clay complexes, their derivation from the original source organic material that would unveil palaeoenvironmental constraints accountable for their origin. The organic and inorganic collides interact with each other and forms clay organic complex which is an important constituent of intercalated bole sediment. Mechanism of interaction between clay and organic compounds in KTB associated sediments is not very well understood. Formation of mixed ligand complexes, sorption and adsorption of organic matter with the inorganic minerals and adsorption of geopolymers in clay inter layers will be studied to infer palaeoenvironmental conditions prevailed at the time of the formation of the intercalated mixed layer clay complexes of Cenomanian-Turonian (C-T) and Maastrichtian-Danian (K-T) boundary sequence of Tiruchirappalli. The adsorption behaviour of organic compounds on surface of clay minerals will be studied in the proposed proposal. The

62

gross structure of heterogeneous geopolymers with special reference to macro-molecular carbon skeleton and its possible linkage with the clay component will be studied in this project using FTIR and NMR spectroscopy.

Proposal 7: Bulk Rock and Clay-Organic Geochemistry, Isotopic Compositions and Dating of Loess-palaeosol Sediments from Dilpur Formation of Kashmir: Palaeoclimatic Reconstruction.

Common association of loess–palaeosol layers in a single succession that makes Karewas unique of its kind. Therefore, it provides one of the most complete terrestrial records of glacial-interglacial cycles of the Quaternary Period (Porter, 2001; Muhs and Bettis, 2003). Such association in Dilpur Formation of Karewas is significant as it reflects arid/dry and warm/humid two distinct palaeo-climatic conditions. Thus, these sequences are considered as past climate indicators and records distinct climatic set-up, correlatable with the regional paleoecology, paleogeography and paleoclimatic changes. Comprehensive continental records covering longer time span are rare, thus, it is difficult to surmise climatic change periodicities. The enrichment of clays and organic matter during the evolution of these sediments provide treasury of information. Therefore, bulk geochemistry, clay mineralogy, organic geochemistry and 10Be and 14C dating of loess-palaeosol sediments associated with the main lithostratigraphic units of the Upper Karewa (Dilpur) Formation is necessary to understand past climatic changes. The cosmogenic radionuclide 10Be (half life = 1.36±0.07 by Nishiizumi et al. 2007) generated much interest as a potential tracer for the environment and finds its application in the present study. Cosmogenic nuclides are produced in rocks and sediments due to reactions induced by cosmic rays. 10Be falls out onto land, lake and ocean surfaces. It gets attached to dust particles. It undergoes dissolution in rain water (Me Hargue and Damon, 1991) and is then scavenged from the water column in lakes and ocean by sinking particles (Anderson et al. 1990). After deposition, 10Be remobilization is generally considered as negligible (Bourles et al. 1989, 1991). Thus, the sedimentary 10Be records can be used as a tracer for Palaeoclimatic interpretations (Shen et al. 1992; Eisenhauer et al. 1994; Aldahan et al. 1997), biological production at the ocean surface (Frank et al. 1994; Rutsch et al. 1995) and geomagnetic field intensity variations (Raisbeck et al. 1985; Lao et al. 1992; Frank et al. 1997). Production rate of cosmogenic isotopes depends upon geomagnetic, latitudinal and altitudinal variations and flux of incoming cosmic rays to the earth (Lal, 1988). Current research on 10Be within terrestrial material requires added sensitivity from AMS techniques. Proposed study is mainly focused on the Upper Karewa Formation, where cosmogenic 10Be isotopes will be employed to understand palaeoclimatic changes occurred within well-constrained Quaternary stratigraphic framework. 14C dating of the Karewa palaeosol carbonate nodules and organic carbon has been done earlier by Kusumgar (1980) and deduced the age range between 18-35ky. But the 14C can be used to date sediments of much narrower ages as well as their smallest difference at profile level which can give the detailed changes in climate with respect to time when correlated with the clay mineralogy and other studies. Organic Carbon is abundant in palaeosols of the Karewa basin therefore it will be used for radiocarbon age determinations. Evaluating the results

63

obtained from both of these dating techniques for Dilpur formation will help in the palaeoclimatic reconstruction.

Proposal 8: Study of limestone of peri-cratonic rift system of Kutch for their abiotic to biotic nature

Rationale: The Kutch basin evolved due to break-up of eastern Gondwanaland in Late Triassic. The Delhi fold belt trend swung in E-W direction in Kutch basin, this led to development of numbers of graben and half-graben in the basin. The rifting initiated from north to south created Kutch embayment however; fully marine condition in basin established later. The oldest Mesozoic deposits of Kutch is located towards north/north-east and youngest sediment deposited towards south-west/west. The Jhurio, Jhumara and Jhuran Formation constitute ~80% of sedimentary sequence of Mesozoic, comprised of limestone and shale whereas Bhuj Formation is dominantly siliciclastic. The limestones of the basin is not of same character and especially early limestones are micritic and completely devoid of fossils/abiotic. The study emphasises on to know why certain limestone of Phanerozoic age is completely devoid of fossils/abiotic. The question arises whether the ocean water chemistry was not favourable for organism, condition was not suitable for preservation of fossil, the style of rifting has controlled the nature of limestone or the ocean circulation pattern was shifted or changed during this time. The rifting of Gondwanaland on other parts of world also crated during this time, we would like to correlate the observation with other rift basins. The secular change of limestone character from abiotic to fossiliferous limestone is not available in literature. We even do not know this is normal behaviour of limestone in rift sediments of Phanerozoic or not.

Objectives:

1. To understand the cause of unfossiliferous to fossiliferous nature of limestone of Kutch rift

2. To understand the ocean water chemistry creating detrimental condition for life during initial stage of rifting though geochemical analysis of limestone

3. To understand the secular change from abiotic to biotic limestone in Kutch rift and its correlation with Phanerozoic rift limestones from other part of world.

Proposal 9: Analysis of Karumolasse in context of Indian-Eurasian collision history

Rationale: It is generally agreed upon that the docking between Indian and Eurasian plate is diachronous along the strike of the Himalayan orogen. Evidences from the north-western edge of the Indian plate suggests it occurred at ~65 Ma (Beck et al. 1995), whereas studies from the Zanskar and Ladakh regions constrain the collision ages to around 52 and 49 Ma. The evidences of collision could be found in the molasses preserved along the suture zone. The Indus and Kargil molasse have been studied for collision ages apart from other aspects. Another small molasse outcrop called Karoo molasse exposed in the suture zone along Leh-Manali highway, has been ignored. But the fact is that it lies in contact with the Ladakh batholith and includes clastics of Ladakh granitides suggest that these mollase sequence could be

64

having wealth of information regarding collision-tectonics and un-roofing of the Ladakh batholith. This study aims to investigate the Karoo molasse sequence to constrain the un-roofing history of the Ladakh batholith.

Objectives:

1. Facies analysis of Karoo molasse sequence2. To understand the Indian-Eurasian collision tectonics and its age constrain

Proposal 10:Evolution of early atmosphere and hydrosphere vis-a-vis linkage is a topic of active research. Several proxy including atypical lithology (iron formation, detrital uraninite, pyrite etc.) , non-mass to mass dependant fractionation in isotopic systematics, sulfur isotope in particular, biomolecule and redox-sensitive trace element behavior are employed by workers to track the change in Earth atmosphere from anoxic to oxic. But, how this atmospheric oxygenation transferred into the hydrosphere from its shallow to deeper level remains a topic of debate. Although it was thought initially that the disappearance of iron Formation from the rock record in post 1.8 Ga time is an indication of deep water oxygenation, the idea is contested by a stratified ocean model by Canfield and coworkers. According to the model in post-1.8 Ga time, ocean became stratified with oxic upper layer and sulfidic bottom layer, similar to present day Black Sea condition. Although this idea is supported by many workers from data around the World, data in Indian context is very rare, if not absent. From a number of basins viz. Vindhyan basin, Gwalior basin, Bijawar basin etc. those range in time span between Paleoproterozoic (~1900 ma) to end Mesoproterozoic (~1000 Ma) and host a number of atypical lithologies viz. iron formation, chert, black shale this study will be attempted to understand the Mesoproterozoic hydrosphere condition in both Indian and global context.

Proposal 11: To track provenance and its temporal shift, if any in basins of central India viz. Chhattisgarh, Ampani, Singhora etc. and Marwar basin, Western India by detrital zircon geochronology and sediment geochemistry (Major, Trace and REE). Indian Precambrian sedimentary basins are studied in last four decades principally on the basis of field- based physical sedimentology, which not only enhanced knowledge on these basins but also improved our knowledge base on Precambrian sedimentology, in general. However, tracking provenance for these basins by use of robust U-Pb detrital zircon geochronology and sediment geochemistry (Nd isotope geochemistry in particular) is only in a nascent stage and hence, many subtle changes in the provenance character vis-à-vis their forcing hinterland tectonics remained in the oblivion. Near surface forcings correlative with deep crustal events can only be tracked from studies in sedimentary basins and in absence of robust geochronology data these near surface forcings remained unnoticed. Under CAS III, attempt will be made to generate high quality detrital zircon data from these basins.

Proposal 12: To evolve tectno-sedimentary model for early Precambrian (Paleoproterozoic) rift basins taking example from the North Delhi Fold Belt (NDFB) i.e the Bayana-Lalsot basin. In view of young Precambrian crust and its low thickness it is assumed that most of faults/ruptures were restricted near surface and

65

subsidence in these fault-bounded basins were unlike fault bounded Phanerozoic basins. PeninsularIndia as a unified continental block shared its late Archean-Proterozoic geological history with its erstwhile neighbors in three successive Precambrian 'Supercontinent's, viz. Ur (3.0 Ga), Columbia (1.9 - 1.8 Ga) and Rodinia (1.1 Ga). Stitching of Archean cratonic nuclei with polyphase orogenic belts, stabilization of cratons with emplacement of granitoids and dyke swarms, opening and closing of intra- and epicratonic sedimentary basins on stabilized craton/s register the ~3.0 billion years(3.5 - 0.5 Ga) Precambrian odyssey of the Indian subcontinent. In this backdrop, it is felt that the sediment archives within Proterozoic basins of India need to be studied both in terms of process-based sedimentology and structural grains present within the basins. As a test case the study is proposed in the Bayana basin, North Delhi fold Belt.

Proposal 13: Attempt will be made to track Paleocene-early Eocene Superthermal events (PETM) from lignite deposits in the Kutch basin, Western India. Earth’s surface experienced a series of transient warming/hypothermal events superimposed on the long warming trend in late Paleocene (¬56 Ma) to early Eocene (¬52 Ma) marked by negative carbon isotope excursions. The 2 to 8 carbon isotope excursion in the early Eocene is is correlated with 5-90 c increase in ocean water temperature in high-latitude areas as well as rise in mean annual temperature of ¬4-50. Release of 1500 to 4500 gigatons of carbon to the ocean and atmosphere resulting in large but poorly constrained increase in CO2 in the atmosphere. This is nearly similar to the 21st century CO2 release pattern and the projected increase in the Earth temperature in next 100 years. Keeping this in view, The late Paleocene lignite section topped by undoubted Eocene limestone will be studied to identify the nature and scale of late Paleocene-early Eocene hypothermal events.

Proposal 14: Paleogene fossil soils of the NW Himalayan Foreland Basin: Implications for the oldest tropical weathering and monsoonal conditions over the Indian subcontinent:

The proposed project is aimed at exploring the oldest fluvial sequences of the HFB from Kangra and Subathu sub-basins to comprehend the past tropical weathering process and inception of the monsoonal conditions over the Indian sub-continent. The paleosols hold an important archive of key paleopedofeatures that are potentially useful to reconstruct the past-weathering processes and paleoenvironments including the inception of monsoonal conditions during Paleogene. In order to achieve the main objective, project work is subdivided into following elements. (i) Identification and field characterization of fossil soils within 3-4 critical sections from Kangra and Subathu basins of the HFB for key paleopedogenic features i.e. paleosol horizons, fossil roots (rhizocretions), pedogenic carbonate nodules, Fe-Mn concretions etc., (ii) Detailed micromorphological characterization of the paleopedofeatures as important clues for paleoclimatic variability, (iii) Geochemical characterization i.e. bulk geochemistry and stable isotope geochemistry of pedogenic carbonates for determining weathering indices and evaluating paleo-precipitation and paleo-temperature during Paleogene.

66

Major objective of the proposed project is aimed at exploring the fossil soils from the oldest continental sediments of the HFB to comprehend inception of paleomonsoon over the Indian sub continent. This can be subdivided into following parts. (i) Identification and field characterization of fossil soils within 3-4 critical sections of Lower Dharamsala and Dagshai Formations from Kangra and Subathu basins of the HFB for key paleopedogenic features i.e. paleosol horizons, fossil roots (rhizocretions), pedogenic carbonate nodules, Fe-Mn concretions etc. (ii) Detailed micromorphological characterization of the paleosols for establishing the key paleopedofeatures i.e. microstructure, rhizocretions, illuviation, pedogenic carbonate and birefringence fabric of the paleosols as important clues for paleoclimatic variability. (iii) Geochemical characterization i.e. bulk geochemistry and stable isotope geochemistry of pedogenic carbonates for determining weathering indices and evaluating paleo-precipitation and paleo-temperature during Paleogene.

Proposal 15:Late Quaternary evolution of the Sutlej River exit.

Objectives: a) To understand the drainage reorganization at Sutlej River exit during Late Quaternary; b) To determine the causes for drainage reorganization;c) Understand the coupling of climate and tectonics in drainage reorganization.

Proposal 16: Initiating Critical Zone Studies

The critical zone is "the living, evolving, outer skin of our planet where rock, soil, water, air and organisms interact to regulate the environment that is critical to life” (Fisher 2012). Today the outer skin of the Earth is scarred by the anthropogenic activities at unprecedented rates and is under pressure due to exponential growth of the population. It has become a major challenge to understand the effect of this human interference with the Earth's CZ. Globally, this challenge has been realised and efforts have been initiated around a decade ago by establishing Critical Zone observatories to address the problems related to basic sciences in Earth surface processes. In contrast, in India in spite of its large size, and topographic and climatic variability, there is only one such observatory.

We propose to initiate research in the field of Critical Zone studies. The potential site for this study would be Himalaya where dynamic interaction between tectonics, and climate occurs. This study is essential in order to understand the Earth surface processes in this terrain because not only will it provide insights of the CZ functioning in this dynamic terrain but it will also demonstrate how sediment and water flux which is essential element that helps millions of people sustain their life on the Ganga Plains flow out of the catchment. The main objectives of this study would be sediment budgeting of a Himalayan basin and investigate the linkages between Critical Zone thickness and factors controlling it.
