[S-CG45] 地球深部とダイナミクス理解の新展開
2022年5月22日(日) 17:15 〜 18:45 国際展示場ホール8
The physical, compositional, and biological state of the present day Earth is a product of a myriad dynamical process over the last 4.5 billion years resulting in a complexly layered structure (core- mantle-crust-biosphere-atmosphere) with various exchanges between layers. Accretion and early di!erentiation resulted in a gravitationally stabilized metallic core, and a silicate Earth that rapidly degassed and di!erentiated to form a crust-ocean system and a distinctive distribution of the radiogenic, heat producing elements in the Earth.
Significant discussion continues on the planform of mantle convective, the structure, mineralogy and composition of the mantle. The role of biology in shaping the oxygen content of the atmosphere, the oxidation state and composition of the crust and possibly that of the mantle is increasingly being recognized and documented. Paramount in the advancement of our science is the role that technological development. Advances in seismic imaging of Earth's interior, drilling deep into the crust and mantle, sensing the deep biosphere, measuring di!erences in the surface flux of geoneutrinos are transforming our understanding of the Earth.
Contributions from biology, seismology, geochemistry, geodynamics, mineral physics and neutrino geophysics are welcomed to this interdisciplinary session that will provide new constraints on and insights into Earth.
