معرفی
Frank Tepley is a Professor and Program Director in the Geology Program at Oregon State University’s College of Earth, Ocean, and Atmospheric Sciences. He specializes in igneous petrology, isotope geochemistry, and electron probe microscopy. His research focuses on magma dynamics, crustal contamination processes, and volcanic system evolution. Tepley holds a B.S. in Geology from California State University, Northridge (1991) and a Ph.D. in Geochemistry from UCLA (1999). His work includes studies on mid-ocean ridge basalts, arc volcanism in Peru and New Zealand, and the application of microprobe analysis to trace magma histories. He directs the Electron Microprobe Laboratory and has led fieldwork on submarine volcanoes like Brothers Volcano in the Kermadec Arc. Key areas of exploration include magma mixing timescales, volcanic eruption chronology, and the role of hydrothermal systems in metal transport.

Research interests emphasize volcanic processes, including magma storage, crustal assimilation, and the use of mineral isotopes to reconstruct magmatic histories. Recent studies explore the evolution of Misti Volcano (Peru), Kermadec Arc submarine systems, and mid-ocean ridge geochemistry. His analytical contributions include refining techniques for trace element and Sr-isotope analysis in plagioclase feldspars.
Publications highlight advancements in understanding magma dynamics through crystal-scale geochemistry and experimental petrology. Current projects focus on volcanic hazard assessment via tephra analysis and magmatic timescale modeling. Tepley’s lab supports collaborative research in electron microprobe analysis for mineral characterization.
