[S-IT40_1PM1] Geofluids: their distribution and role in the Earth's dynamics

Thu. May 1, 2014 2:15 PM - 4:00 PM 416 (4F)

Convener:*Michihiko Nakamura(Division of Earth and Planetary Materials Science, Department of Earth Science, Graduate School of Science, Tohoku University), Hiroshi Sakuma(Department of Earth and Planetary Sciences, Graduate School of Science and Engineering, Tokyo Institute of Technology), Masahiro Ichiki(Graduate School of Science, Tohoku University), Tsutomu Takahashi(Institute for Research on Earth Evolution Japan Agency for Marine-Earth Science and Technology), Chair:Tetsuya Yokoyama(Department of Earth and Planetary Sciences, Graduate School of Science and Engineering, Tokyo Institute of Technology), Keika Horiguchi(Crustal Fluid Research Group, The Institute of Geology and Geoinformation, Geological Survey of Japan, National Institute of Advanced Industrial Science and Technology)

Recent advances of magnetotelluric and seismic imaging of the Earth's interior have suggested "geofluids" distribute more ubiquitously than ever thought; this has accelerated the development of a new integrated discipline on the geofluids ranging from material sciences in molecular scale to geophysics and geochemistry in the island arcs and mid oceanic ridges. The scope of this session is to bring together multi-scale and interdisciplinary researches on distributions of aqueous fluids and silicate and other melts in the crust and mantle of a wide range of tectonic settings, and on the physical and chemical properties of these fluids. Topics on geodynamics related to the presence of fluids are also welcomed.

2:15 PM - 2:30 PM
