Marlon Jean, PhD, currently teaches GEOL111 and GEOL111L. He will be teaching Mineralogy & Igneous Petrology in the coming semesters. His research utilizes the major element, trace element, and isotopic composition of ultramafic to mafic, volcanic and plutonic rocks, with a main focus on the life cycle of oceanic and continental lithosphere in the US Cordillera. Jean is currently investigating (1) primitive, modally layered gabbroic rocks from the lower plutonic crust formed at a fast-spreading ridge, sampled by IODP at the Hess Deep rift; (2) Martian and Lunar meteorites; (3) Gold deposits from Nevada; and (4) drillcore from Unalaska Island, Alaska. If students, prospective students or others are interested in any of these projects, please feel free to reach out to Jean.
