Teleseismic images suggest that the Tarim plate plunges ~45°S, down to ~300 km depth, beneath NW Tibet. The 410 km discontinuity shallows by ~10 km under the plateau, implying ~100°C cooler upper mantle. The deepest Moho on record (~90 km) lies under W Qiangtang. It rises abruptly by ~20 and ~10 km beneath the Altyn Tagh Fault and Bangong Suture, respectively. Vp/Vs ratios are normal, except in the Yecheng flexural basin and deep under the south Karakax volcanics (~1.92). W Kunlun's Neogene tectonics are simply accounted for by oblique subduction of lithospheric mantle beneath an upward-extruding thrust wedge of the Tarim crust.
