[S-IT07] Structure and dynamics of Earth and Planetary deep interiors

Sun. May 22, 2016 10:45 AM - 12:15 PM 201B (2F)

Convener:*Takashi Yoshino(Institute for Study of the Earth's Interior, Okayama University), Dapeng Zhao(Department of Geophysics, Tohoku University), Takashi Nakagawa(JAMSTEC/MAT), Chair:Takashi Yoshino(Institute for Study of the Earth's Interior, Okayama University), Koichiro Umemoto(Earth-Life Science Institute, Tokyo Institute of Technology)

Interdisciplinary approach can lead to a better understanding of dynamics and evolution of the deep interiors of the Earth and planets. We welcome any submissions of recent results in observational, theoretical and experimental studies on seismology, geomagnetism, mineral physics, dynamics of deep interiors, and any other relevant fields from researchers in many countries. Integration of such results is also welcome.
