Studies on crust/mantle structure and deep dynamic process beneath Tibetan plateau, are among hot-topics and lead edge in the current earth science field, numerous crust/mantle deformation models are poorly constrained with lack of geophysical data.

 Research groups from Institute of Geology and Geophysics and Institute of Tibetan Plateau Research, carried out active and passive source seismic profiling to image the Moho (the crust-mantle boundary) and the LAB (the lithosphere-Asthenosphere Boundary) of the plateau. These studies defined the collision boundary between the Indian and Asian plates and its dynamic process, where the lead edge of the subducted Indian plate are Tarim basin and the eastern syntaxis from west to east; and propose a new mountain building mechanism with the interaction between deep process and the shallow tectonic responses to explain Longmenshan’s high topography gradient, put forward the two stages deformation model of interaction and deformation between the East Tibetan escaping flow and Sichuan basin, and provides geophysical evidence of two channels crustal flow beneath the eastern syntaxis of Tibetan plateau. The related results were published in PANS, Nature-Geoscience and EPSL.
