[S-CG62_2AM2] Geofluids and dynamics in subduction zones

Fri. May 2, 2014 11:00 AM - 12:45 PM 502 (5F)

Convener:*Atsushi Okamoto(Graduate School of Environmental Studies), Tatsuhiko Kawamoto(Institute for Geothermal Sciences, Graduate School of Science, Kyoto University), Ikuo Katayama(Department of Earth and Planetary Systems Science, Hiroshima University), Chair:Tatsuhiko Kawamoto(Institute for Geothermal Sciences, Graduate School of Science, Kyoto University), Atsushi Okamoto(Graduate School of Environmental Studies)

Fluids from subducting slabs trigger earthquakes and low frequency tremors, and return back as springs in for-arc regions and produce magmas beneath volcanic arcs. Geofluids can be present everywhere and migrate in subduction zones and produce spatial and temporal variations in physical and chemical properties of materials. Thus the geofluids play an important role in the subduction-zone dynamics. This interdisciplinary session aims to promote the exchange of knowledge from cutting edge studies on geofluids and give perspectives to each participant. We continue to strongly encourage young researchers to participate in this session, because understanding geofluids can be essential in many geological and geophysical processes.

11:30 AM - 11:45 AM
