"Tales of the Deep Earth": A Look at the History and Future of Mineral Physics and High Pressure Experimental Research in the Geosciences

Date: March 1, 2013 Time: 11:00 a.m. Location: Brattain Auditorium, Hall of Sciences

What lies deep beneath our feet on planet Earth? How do common minerals and rocks behave at high temperatures and pressures? How do the materials and properties of the deep interior influence plate tectonics, mountain building, heat loss, climate and other geological processes we observe at the surface? To answer these questions, mineral physicists study materials under conditions likely to exist deep in planetary interiors. In this talk, I will outline some of the history, tools and recent major findings of high pressure mineral physics and discuss how deep earth processes influence surface processes such as plate tectonics, volatile distributions, and climate.

Jim Tyburczy received his bachelor's degree in chemistry-environmental studies at Whitman College and his Ph.D. in physical chemistry at the University of Oregon. He was a postdoctoral fellow at the California Institute of Technology before joining Arizona State University in 1986. He is currently Professor of Geology in the ASU School of Earth and Space Exploration where he explores the behavior of geomaterials under extreme conditions.
