AbstractWe obtained a panoptic view of the pattern of mantle flow in the "Big Mantle Wedge" associated with the stagnation of the subducting Pacific slab. We applied a simultaneous inversion of multiple waveforms method to measure SKS-wave splitting parameters for a dense seismic array in trans-continental Northeast Asia. We identify distinct patterns separated by the North-South Gravity Lineament (NSGL): to the west, the ENE fast axis orientation with small delta t reflects limited frozen anisotropy in the stable lithosphere; while to the east, local variation of anisotropy is superimposed on the NNW-dominated fast direction, suggesting contribution of other mechanisms rather than the only asthenospheric flow. Within a distance of 200 km crossing the NSGL, we reveal a gradual clockwise rotation in the fast direction, and the keel-deflected flow caused by the 60-80 km reduction in the lithosphere thickness across the NSGL might contribute to the variation of anisotropy.
