This Keck project is an interdisciplinary investigation of biologically mediated precipitation of dolomite and other carbonate minerals in Deep Springs Lake, CA. Elucidating the mechanisms of modern dolomite precipitation is a fundamental and longstanding problem in sedimentology and Earth history. Students and faculty will develop an integrated suite of field and laboratory data utilizing techniques in microbiology, aqueous geochemistry, sedimentology, mineralogy, and isotope geochemistry. During the project, participants will have the opportunity to perform cutting-edge geobiological research, including one week of fieldwork in a modern alkaline playa lake and three weeks of lab research at the sponsoring institutions.
