[S-MP28] Deformed rocks, Metamorphic rocks and Tectonics

Tue. May 27, 2025 1:45 PM - 3:15 PM 201B (International Conference Hall, Makuhari Messe)

convener:Takayoshi Nagaya(Tokyo Gakugei University), Ken Yamaoka(National Institute of Advanced Industrial Science and Technology), Yoshihiro Nakamura(Geological Survey of Japan, National Institute of Advanced Industrial Science and Technology), Chairperson:Miki Tasaka(Shizuoka University), Takayoshi Nagaya(Tokyo Gakugei University)

We invite all researchers who aim to understand the dynamics of the earth's crust and mantle at the plate boundaries, to discuss the latest results from various viewpoints. The scope will include contributions through petrology and structural geology as well as various techniques including rheology and transformation of heat and mass.
