PPT-Minerals in rock thin sections

Rock thin sections Rock thin sections are slices of rock glued onto microscope slides and polished until they are about 30μm thick about the thickness of human hair The microscope used to study minerals in rock thin sections. Igneous Rock. Born of Fire. Origin of Igneous Rock. Magma cools and forms various types of igneous rock. Depends on composition and time it takes to cool. “Freezes” to form igneous rock..

On Mars, billion-year-old sedimentary rocks containing clay minerals are key indicators of ancient habitable environments and may preserve organic compounds. On Earth, where plate tectonics drives the burial and heating of rocks, clay minerals are transformed into new minerals, influencing organic preservation, and impacting global geochemical cycling of carbon, oxygen, and water. Mars lacked plate tectonics for much of its history, but data from Mars Science Laboratory Rover, .
