Deep process of the collision and deformation on the northern margin of the Tibetan Plateau: Revelation from investigation of the deep seismic profiles

The seismic investigation achievements from three kinds of methods have revealed the lithospheric structure and the deep process of deformation caused by collision. It is found that convergent collision and deep subduction of the continental lithosphere are in progress along the northern margin of the Tibetan Plateau. The deep process of due collision and deformation is different from that of oblique collision. It is revealed in the study that the deep process of the collision and deformation on the northern margin is different from that on the southern margin of the Tibetan Plateau.
