[S-IT03_29PM1] Structure and dynamics of Earth and Planetary deep interiors

Tue. Apr 29, 2014 2:15 PM - 4:00 PM 418 (4F)

Convener:*Satoru Tanaka(Institute for Research on Earth Evolution Japan Agency for Marine-Earth Science and Technology), Takashi Yoshino(Institute for Study of the Earth's Interior, Okayama University), Masanori Kameyama(Geodynamics Research Center, Ehime University), Dapeng Zhao(Department of Geophysics, Tohoku University), John Hernlund(ELSI, Tokyo TECH), Chair:Satoru Tanaka(Institute for Research on Earth Evolution Japan Agency for Marine-Earth Science and Technology), Hidenori Terasaki(Graduate School of Science, Osaka University)

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.
