Recent observational and experimental investigations have significantly advanced our understanding of the deep Earth's structure and constituent materials. Yet, even fundamental properties intimately linked with the formation and evolution of the planet, such as details of the chemical heterogeneity in the mantle and light elements dissolved in the core, remain unclear. Seismological observations have suggested vigorous convection in the lower mantle, whereas geochemistry has suggested the presence of stable regions there that hold ancient isotope signatures. The amounts of radioactive isotopes that act as heat sources and drive the deep Earth's dynamic behaviors 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 the establishment of the Japan-SEDI community are also welcomed.
