Materials in Extreme Environments
from Geology Bites · host Oliver Strimpel
Most of the material in the Earth and other planets exists under extremes of pressure and temperature quite unlike those we inhabit on the surface of the Earth. Steve Jacobsen is a mineral physicist who studies how rocks and minerals behave under such alien conditions. In the podcast, we discuss his experiments and what we’ve learned about three extreme environments: the core-mantle boundary, the mantle transition zone, and the surface of the Moon.Jacobsen is a Professor of Geological Sciences at the University of Colorado Boulder. The image shows him in his optical spectroscopy lab, where extreme conditions found throughout the solar system are re-created.
