[S-IT04] Rheology of Earth's Interior

2015年5月28日(木) 16:15 〜 18:00 106 (1F)

コンビーナ:*大内 智博(愛媛大学地球深部ダイナミクス研究センター)、唐戸 俊一郎(Yale University, Department of Geology and Geophysics)、道林 克禎(静岡大学理学研究科地球科学専攻)、座長:道林 克禎(静岡大学理学研究科地球科学専攻)

Recently, rheological properties of minerals, which form the interior of the Earth, have been understood. We need to revisit the dynamics of the Earth based on recent results, and we seek to formulate future directions of the study of rheology. We welcome contributions on rheological properties (i.e., ductile/semi-brittle/plastic flow, seismic anisotropy and attenuation, and so on) of the lithosphere, asthenosphere, and core of the Earth, from a broad variety of disciplines including mineral and rock physics, geology, geodynamics and any other relevant fields. Topics related to transportation properties of materials in the interior of the Earth are also welcomed.
