[S-IT11] Geodynamic evolution of northeast Asia and western Pacific

Tue. May 24, 2016 5:15 PM - 6:30 PM Poster Hall (International Exhibition Hall HALL6)

Convener:*Gaku Kimura(Department of Earth and Planetary Science of the Graduate School of Science, The University of Tokyo), Jonny Wu(Department of Geosciences, National Taiwan University), Timothy Byrne(University of Connecticut), Kyoko Okino(Ocean Research Institute, University of Tokyo)

The session aims to draw new observational constrains, geodynamic models, and novel syntheses, that have implications for the Mesozoic to present-day tectonic reconstruction of the NE Asian margin and western Pacific region. Long lived subduction, accretion, collision and the formation of new basis have shaped the vast region that today includes, the Japan Sea, the East China Sea, the South China Sea, the Philippine Sea, the western Pacific, china, Taiwan, the Korea Peninsula and Japan. Rapid advances in imaging techniques have provided new high resolution, crustal to lithospheric scale models of NE Asias basins and cartoons. We invite contributions from across the dicliplines including geology, seismology, marine geophysics, sedimentology, geodesy, paleomagnetism, geochronology, and geodynamic modeling.
