3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3 From: Cathy Busby <cjbusby@xxxxxxxxxxx> 3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3 A PhD student is sought for a new NSF award to Cathy Busby (University of California, Davis) in a collaborative proposal with Keith Putirka (California State University, Fresno). Potential applicants should contact Cathy Busby for details, and qualified students will be encouraged to apply to UC Davis Department of Earth and Planetary Sciences for admission in Fall, 2020. The PhD studentâ??s support and fieldwork will begin in summer 2020. Our work examines the controls of Walker Lane faults on magmatism, linking temporal variation in subsidence rates, as well as pull-apart basin sizes, with vent types, eruptive styles, eruptive volumes and rates, and the depth extent of volcanic conduits. We will test whether tectonic events control: (1) depths and temperatures of magma storage, and (2) the types of mantle sources that deliver mafic melts to the crust. This study will yield insights that cannot be gained by examining modern volcanoes, whose structural controls are buried by volcanic and sedimentary deposits (e.g. active volcanic centers in Walker Lane pull-apart basins such as Lassen, Long Valley and Coso). Busby seeks candidates with a strong background in geologic mapping, preferably with an MS degree. Geologic mapping will include volcanic stratigraphic analysis and structural analysis. Laboratory work will include petrography, geochemistry, mineral chemistry, and 40Ar-39Argeochronology. Published papers on our work in the Sierra Nevada/Walker Lane are posted at http://www.geol.ucsb.edu/faculty/busby. The Department of Earth and Planetary Sciences at UC Davis has 25 full faculty members, 14 scientists and academic federation members, and numerous postdocs and associates, with a high proportion of females on faculty. A large number of graduate students and undergraduate geology majors help to create a vibrant community in the department.
