Physics, Chemistry, and Petrology of Earth's Deep Mantle and Core I Posters

Submit an Abstract to this Session



Session ID#: 34589

Session Description:
Recently, geophysical observations have revealed that the Earth’s deep mantle and core are more complex than previously thought. At same time, advances in experimental and analytical techniques now enable the routine investigation of chemical reactions between planetary materials under high pressure and temperature (P-T) conditions exceeding Earth's core-mantle boundary. In this session, we focus on the physics, chemistry, and petrology of the Earth’s deep mantle and core at very high P-T to better understand 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. Topics include, but are not limited to, phase relations, thermodynamics, elasticity, EOS, crystal chemistry, and transport and rheological properties. We also welcome contributions from seismology, geodynamics, and geochemistry to provide a unified view of deep Earth.
