[S-IT38_30AM2] Rheology and Transport Phenomena of Geomaterials

Wed. Apr 30, 2014 11:00 AM - 12:45 PM 511 (5F)

Convener:*Tomohiro Ohuchi(Geodynamics Research Center, Ehime University), Osamu Kuwano(Japan Agency for Marin-Earth Science and Technology), Ichiko Shimizu(Department of Earth and Planetary Science, Graduate School of Science, University of Tokyo), Chair:Osamu Kuwano(Japan Agency for Marin-Earth Science and Technology)

Dealing with various deformation processes, rheology, and transport phenomena in the crust, mantle and the core. Our goal is to achieve a unified understanding of solid earth science from the viewpoint of rheology. We welcome any approach: field observations, laboratory experiments, numerical simulations, and theories. Interdisciplinary studies on deformation processes (e.g., industrial or materials science) are also welcome in this session.
