スコープ和文近年の高圧実験の進歩で、地球中心部に至る温度圧力条件での鉱物の物性測定が可能となってきた。一方、高精度な古地磁気測定、地球物理学観測、精密地球物理学分析、地球ニュートリノによる地球深部放射性物質の直接観測などの発展と共に、マントル対流や地磁気ダイナモの数値シミュレーション技術も大きく発展して、地球内部の状態の理解が進んできた。本セッションでは、地球及び惑星における核−マントル相互作用と進化に焦点をあてた、様々な研究分野の成果を一堂に会する機会を提供し、情報交換を進めることを目的とする。異なる分野間の連携を発展させるための日本版地球・惑星深部研究グループ(J-SEDI)の形成に関わる講演も歓迎する。
英文Recent observational and experimental investigations have significantly advanced our understanding of the structure and constituent materials of the deep Earth. Yet, 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, remained unclear. Seismological evidence has suggested a vigorous convection in the lower mantle, whereas geochemistry has suggested the presence of stable regions there that hold ancient chemical signatures. The amounts of radioactive isotopes that act as heat sources and drive dynamic behaviors of the deep Earth are also still largely unknown. We provide an opportunity to exchange the achievements and ideas, and encourage persons who try to elucidate these unsolved issues of the core-mantle evolution using various methods, including high-pressure and high-temperature experiments, high-precision geochemical and paleomagnetic analyses, high-resolution geophysical observations, geo-neutrino observations, and large-scale numerical simulations. Papers stimulating an interdisciplinary collaboration relating to establishment of the Japan-SEDI community are also welcomed.
