Magmatic and Eruptive Processes

A dive into the processes involved in the generation, evolution, and eruption of magmas through the lens of local (northern California) magmatism. Explore concepts related to the compositional and textural evolution of magmas, including: the structure and physical properties of magmas; use of geobarometers and geothermometers to determine conditions of magmatic processes; melting and magmatic lineages as a function of tectonic setting; processes that control magma composition; petrogenetic use of trace elements and isotopes. Three optional weekend fieldtrips to localities explored in weekly (1 hr/week) meetings will reinforce and enhance knowledge obtained from reading and discussion of scientific journal articles. Students participating in weekly meetings only should register for 1 unit, those participating in fieldtrips (minimum two of three) should register for 3 units. This course must be taken for a minimum of 3 units and a letter grade to be eligible for Ways credit. GEOLSCI 1, GEOLSCI 2, or consent of instructor are prerequisites.
