[S-MP31] Deformation, metamorphism, and tectonics: Exploring the solid Earth dynamics via rocks

Mon. May 25, 2026 1:45 PM - 3:15 PM International Conference Room (IC) (International Conference Hall, Makuhari Messe)

Chairperson:Fukushima Ryo(Kochi Institute for Core Sample Research, Japan Agency for Marine-Earth Science and Technology), Nakamura Yoshihiro(Geological Survey of Japan, National Institute of Advanced Industrial Science and Technology)

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 heat and mass transfer.
