Prof. Eiji Ohtani is among the earliest leaders of deep earth mineralogy, geophysics and geochemistry, and remains so to this day. Central themes of his career, and the focus of this session, are experimental study of high temperature/pressure mineralogy, geophysics and geochemistry, of terrestrial and extraterrestrial materials (meteorites), which he deploys to model formation and evolution of the interior of the Earth and terrestrial planets. These include partial melting of deep silicate earth, element partitioning, role of hydrous circulation of water and hydrogen in the early deep Earth, and core/mantle equilibria together with equation-of-state of silicate mantle and metal core materials.

This session aims to bring together high-pressure/-temperature experiment on physics and chemistry of deep Earth materials, natural observation, and theoretical modeling within the principal subject areas of "Early Earth" research emphasizing;

(1) Shock events: discover of high pressure minerals in shocked meteorites
(2) Magma ocean: melting behavior of Earth and planetary materials and properties of melts at high pressures and temperatures
(3) Core formation: mineralogy, geochemistry, and physical properties of the core and core-mantle boundary
