[S-MP48_2PM2] Dynamics of melt, ductile and brittle rock mass and energy system

Fri. May 2, 2014 4:15 PM - 5:00 PM 313 (3F)

Convener:*Noriyoshi Tsuchiya(Graduate School of Environmental Studies, Tohoku University), Hiroshi Asanuma(AIST), Hiurofumi Muraoka(North Japan Research Institute for Sustainable Energy, Hirosaki University), Hisao Ito(JAPAN MARINE SCIENCE & TECHNOLOGY CENTER), Chair:Noriyoshi Tsuchiya(Graduate School of Environmental Studies, Tohoku University)

Nature of rock mass below the brittle-ductile transition (BDT) is of great scientific interest to understand various phenomenon in the earth's crust. We will review and discuss current understanding of characteristics the rock mass below the BDT, including composites, stress, failure mechanism induced by liquid injection and associates earthquake generation mechanism, and water rock interaction, considering engineered geothermal development in the BDT. Discussions on the possible phenomena in the geothermal development in the BDT will be followed in this session. This session is closely related to JBBP (Japan Beyond Brittle Project) under ICDP.
