[S-IT29] [EE] New perspectives on East Asia geodynamics from the crust to the mantle

Tue. May 23, 2017 10:45 AM - 12:15 PM A03 (Tokyo Bay Makuhari Hall)

convener:Timothy B Byrne(University of Connecticut), Gaku Kimura(Tokyo University of Marine Science and Technology), Jonny Wu(University of Houston), Kyoko Okino(Atmosphere and Ocean Research Institute, The University of Tokyo), Chairperson:Gaku Kimura(Tokyo University of Marine Science and Technology), Chairperson:Jonny Wu(University of Houston)

The Philippine Sea plate and smaller East Asia marginal basins have been sandwiched by convergence of the larger Pacific and Indo-Australian plates towards Eurasia, producing some of the most active tectonic environments on Earth. The last decade has yielded a wide range of new observations that include geologic data along the plate margins, crustal to mantle imaging, and the geometry of subducted slabs. Together, these new perspectives have important implications for understanding the dynamics of plate interactions in this region. Here we seek oral and poster presentations that bear on the geologic history and geophysical character of modern and ancient plates in East Asia. We also invite geodynamic models that integrate these diverse datasets into a more holistic view of this dynamic environment.
