Class Goals• Recognize major rock-forming minerals and other
selected minerals in hand specimen and thin section
• Master use of several techniques for the identification of minerals using the petrographic microscope
• Develop the ability to relate crystal chemistry, crystallographic alignment, and physical attributes of a mineral to guide identification and assess a mineral’s origin and history

Metamorphic settings

Orogenic settings

Ore deposits

Oil

Sedimentary deposition• Weathering of any rock and transport of that
material to lower E environment followed by lithification yields sed. rx

Depositional settings
• Keyed to transport of physical/ chemical components of parent material
• Tells 2 stories – who were the parents and how far away did it go?

Chemical deposition
• Formation of minerals from aqueous solution requires some change in environment for the ions to precipitate
![Page 20: Geol 110 Earth Materials](https://reader035.fdocuments.in/reader035/viewer/2022062314/56812caa550346895d9156af/html5/thumbnails/20.jpg)
Fossils• Here parent material were organisms – usually
ones that were partially composed of a durable mineral material
• Requires a special depositional setting– Quick burial, fine/ chemical covering, replacement
reactions
• Also tell us approximate age of deposition

Biominerals• Microorganisms may
also have a significant impact on mineralogy!
