Geological Boundary Transitional TOPOGRAPHIC FEATURES Towns Roads Railway line Rivers Water body International Boundary MAP HISTORY "LINEAMENTS" are significant lines of landscapes which reveal the hidden architecture of the rock basement. Lineaments are essentially rectilinear features resulting from fracturing/faulting or structurally controlled topographic lines. They are in fact character lines of the earth's "Physiognomy". The 2006 Edition of the Lineaments Map of Nigeria contains more elements than the 1986 Edition of the Fracture map of Nigeria. Features depicted include; A) Fractures, faults,scarp surfaces, bars, ridges, photo-geological linears etc. B) Faults/fractures deduced from the interpretation of Aero-magnetic maps to indicate/compare subsurface faulting/fracturing. C) Fracture patterns delineated into domains of fracture systems - most probably influenced by the lithology, tectonic/volcanic history, or denudation. Lineaments maps are invaluable tools for a. Foundation and civil engineering constructions. b. Detection of potential zones of oil-gas/minerals/water accumulation c. Earth quakes and natural hazards monitoring. DATA SOURCES:- collation of lithological and fracture data on state by state basis. i. Reappraisal of previous edition and records of NGSA (published & unpublished) and learned journals. ii. Reassessment of 1:m SLAR Mosaic and landsat. iii. Aeromagnetic interpretation maps by Pal-service (1973-4) iv. Aeromagnetic map of Ogun state, 2003. FAULT / FRACTURE PATTERNS I.

MAP HISTORY"LINEAMENTS" are significant lines of landscapes which reveal the hiddenarchitecture of the rock basement. Lineaments are essentially rectilinear features resulting from fracturing/faulting or structurally controlled topographic lines. They are in fact character lines of the earth's "Physiognomy".The 2006 Edition of the Lineaments Map of Nigeria contains more elements than the 1986 Edition of the Fracture map of Nigeria. Features depicted include;A) Fractures, faults,scarp surfaces, bars, ridges, photo-geological linears etc.B) Faults/fractures deduced from the interpretation of Aero-magnetic maps to indicate/compare subsurface faulting/fracturing.C) Fracture patterns delineated into domains of fracture systems - most probably influenced by the lithology, tectonic/volcanic history, or denudation.Lineaments maps are invaluable tools for a. Foundation and civil engineering constructions.b. Detection of potential zones of oil-gas/minerals/water accumulationc. Earth quakes and natural hazards monitoring.DATA SOURCES:- collation of lithological and fracture data on state by state basis.i. Reappraisal of previous edition and records of NGSA (published & unpublished) and learned journals.ii. Reassessment of 1:m SLAR Mosaic and landsat.iii. Aeromagnetic interpretation maps by Pal-service (1973-4)iv. Aeromagnetic map of Ogun state, 2003.
