Evidence from Caustic Waveform Modeling for Long Slab Thickening above the 660?km Discontinuity under Northeast Asia: Dynamic Implications
Original language description
Knowledge of thickness of the slab is of great importance in understanding the deformation of subducting lithosphere and the mantle rheology which are closely related to the ongoing geodynamic process. Seismic tomography technique has been used widely indetecting thermal-related mantle heterogeneities, however, poor resolution is obtained in constraints of slab image, especially in the mantle transition zone. In this study, we aimed to constrain the thickness of the slab in the MTZ beneath northeast Asia through a method of caustic waveform modeling for both P and S waves. We detect a high velocity layer associated with a thickened slab lying in the upper mantle transition zone (MTZ), and the refined thickness is estimated to be ~140 +-20 km. Our results suggest that the slab is 50-60 km thickened at the long-stagnant portion, indicating an ongoing piling up of slabs under Northeast Asia. We argue that the slab might be on the margin of an instable state. Based on our numerical simula
