MR016:
Petrology, Partitioning, and Phase Diagrams at Extreme Conditions





Session ID#: 25430

Session Description:
This session focuses on the petrology of materials at very high pressures and temperatures (P-T). Recent advances in experimental and analytical techniques now enable the routine investigation of chemical reactions between planetary materials under P-T conditions exceeding Earth's core-mantle boundary. High P-T reactions, and corresponding phase diagrams, dictate fundamental phenomena in planetary evolution, including magma ocean crystallization, bulk core compositions, the growth of Earth's inner core, maintaining dynamos, partial melting in the lower-most mantle, the deep transport and sequestration of volatiles, and the potential properties of terrestrial exoplanets. We encourage contributions from experimental and theoretical studies of partitioning, phase diagrams, and other petrological processes at extreme conditions aimed at understanding planetary formation and long-term evolution. We also encourage complementary contributions from geochemistry and geophysics.
