Sedimentary Geochemistry and Analysis

Catalog description

Introduction to research methods in sedimentary geochemistry. Proper laboratory techniques and strategies for generating reliable data applicable to any future lab work will be emphasized. This research-based course will examine how the geochemistry of sedimentary rocks informs us about local and global environmental conditions during deposition. Students will collect geochemical data from a measured stratigraphic section in the western United States. These samples will be collected during a four-day field trip at the end of spring break (attendance encouraged but not required). In lab, students will learn low-temperature geochemical techniques focusing on the cycling of biogeochemical elements (O, C, S, and Fe) in marine sediments throughout Earth history. The focus will be on geochemistry of fine-grained siliciclastic rocks (shale) but the geochemistry of carbonates will also be explored. This is a lab-based course complemented with lectures. Students who wish to take the course for less than 4 units must receive approval from the instructor. This course must be taken for a minimum of 3 units and a letter grade to be eligible for WAYS credit.
