[SIT32-P06] Core-mantle boundary structure beneath the Tibetan Plateau and adjacent regions
Keywords:core-mantle boundary, Tibetan Plateau, slant stack
The corrected ScS-S differential travel time residuals indicate that a high shear velocity anomaly beneath the Tibetan plateau is adjacent to a low shear velocity anomaly to the west of Tibetan plateau. Slant stacks of Scd signals show that a discontinuity on top of D” exists near the boundary of high and low velocity anomalies. Precursors of ScP to the south of this boundary suggest the existence of ultralow velocity zone (ULVZ).
