[S-IT22] [EE] Interaction and Coevolution of the Core and Mantle in the Earth and Planets

Mon. May 22, 2017 3:30 PM - 5:00 PM Convention Hall B (International Conference Hall 2F)

convener:Taku Tsuchiya(Geodynamics Research Center, Ehime University), Hidenori Terasaki(Graduate School of Science, Osaka University), Madhusoodhan Satish-Kumar(Department of Geology, Faculty of Science, Niigata University), Tetsuo Irifune(Geodynamics Research Center, Ehime University), John Hernlund(Earth-Life Science Institute, Tokyo Institute of Technology), Eiji Ohtani(Department of Earth and Planetary Materials Science, Graduate School of Science, Tohoku University), Chairperson:Taku Tsuchiya(Geodynamics Research Center, Ehime University)

Recent observational and experimental investigations have significantly advanced our understanding of the structure and constituent materials of the deep Earth. However, even fundamental properties intimately linked with formation and evolution of the planet, such as details of the chemical heterogeneity in the mantle and light elements dissolved in the core, have remained unclear for over 60 years. Seismological evidence has suggested a vigorous convection in the lower mantle, whereas geochemistry has suggested the presence of stable regions there that hold the chemical signature of early Earth. The amounts of radioactive isotopes that act as the heat sources that drive the dynamic behaviors of the deep Earth are also still largely unknown. We provide an opportunity to exchange the achievements and ideas, and encourage the persons who try to elucidate these unresolved mysteries in the Earth and planetary interiors through comprehensive investigations of the interactions between the core and mantle by combining high-pressure and high-temperature experiments, microscale geochemical analysis, high-resolution geophysical observations, geo-neutrino observations and large-scale numerical simulations.
