Scope This session aims to draw together new observational constraints, geodynamic models, and novel syntheses that have implications for the Mesozoic to present-day tectonic reconstruction of the NE Asian margin. Long-lived subduction, accretion, collision, and the formation of new marginal basins 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, Japan and the Korean peninsula. Rapid advances in imaging techniques have provided new high-resolution, crustal to lithospheric-scale models of NE Asian basins, slabs and cratons. We invite contributions from across the disciplines including geology, seismology, marine geophysics, sedimentology, geodesy, paleomagnetism, geochronology, and geodynamic modeling.
