GS 180: Igneous Processes

None

Project description

For juniors, seniors and beginning graduate students in Earth Sciences. Structure and physical properties of magmas; use of phase equilibria and mineral barometers and thermometers to determine conditions of magmatic processes; melting and magmatic lineages as a function of tectonic setting; processes that control magma composition including fractional crystallization, partial melting, and assimilation; petrogenetic use of trace elements and isotopes. Optional labs emphasize identification of volcanic and plutonic rocks in thin section and interpretation of rock textures. Students taking the lab component should enroll in 4 units, as required for the Geological Sciences major; for the lab, GS 102, 103, or consent of instructor are prerequisites.
