Description: We simulate the conditions inside Earth and other planets using experiments in the laser-heated diamond anvil cell at high pressures (up to 2.5 Mbar) and temperatures (up to 6000 K). We are interested in the effects of these extreme conditions on phase equilibria and physical properties of planetary materials including mantle silicates and carbonates. Our laboratory probes crystal structures…
We simulate the conditions inside Earth and other planets using experiments in the laser-heated diamond anvil cell at high pressures (up to 2.5 Mbar) and temperatures (up to 6000 K). We are interested in the effects of these extreme conditions on phase equilibria and physical properties of planetary materials including mantle silicates and carbonates. Our laboratory probes crystal structures and compositions in situ using synchrotron diffraction and spectroscopy and ex situ using electron microscopy techniq
