The top of the upper mantle is a key area for energy transfer and material exchange in the crust and lithospheric mantle. The Lhasa block locates between the Yarlung Zangbo suture zone and the Bangong Nujiang suture zone. The Indian continent continues to collide and subduct northward beneath this area. The Qinghai-Tibet Plateau rapidly uplifts for a long time in the past. There are a large number of NEtrending rift systems formed by east-west extension. In the Lhasa-Shigatse region, we deployed a broadband-measured line measuring nearly 300 km with an average spacing of 10 km across the Yangbajian Rift Belt.
