ESCI 502 – Field Trip-Advanced Geology and Petrology
Instructor: Cin-Ty Lee
To sign up for this course, you must get the instructor’s signature.
This class will combine field geology with quantitative understanding of the physical and chemical processes relevant to various geological phenomena, such as magma mixing, ductile and brittle deformation, regional and contact metamorphism, regional tectonics, structural geology, sedimentology, and geomorphology. The class will meet once a week for 2 hours and will begin with a lecture by the instructor, followed by student-led discussions of assigned readings. A 3 day field trip to Southern California is planned. The first day will be spent mapping magma mingling structures. On the second day, students will split into two groups, depending on interest to map either 1) structural and metamorphic contact relationships between a plutonic body and carbonate wallrock, or 2) alluvial fan deposits in a tectonically active region. Depending on time, on the third day will involve a geologic tour of southern California, including the San Jacinto Mountains, San Andreas Fault, Salton trough, Joshua Tree National Park, and various metamorphic rocks in the transverse ranges.
Students are expected to have taken all the ESCI core classes or equivalents as well as the field methods course. Basic math, physics and chemistry are recommended.
