Model of crust and upper mantle velocity structure in the Tibetan Plateau

In the geophysical study of the Tibetan Plateau, the velocity distribution of crust and mantle media is the basis for exploring the behavior, trajectory and dynamic response of material movement in the hinterland and surrounding areas of the plateau. Through the high-precision artificial source seismic exploration and inversion implemented in plateau areas for more than 50 years, the characterization of the fine structure of crust and mantle medium and the velocity distribution of each sequence have been obtained. Based on artificial source seismic deep exploration, reference and natural seismic and MT sounding results, the average velocity structure model of the crust and mantle layer medium in the Tibetan Plateau is accordingly established. Paying attention to both physical structure and velocity structure, developing high-precision observation equipment and multi-dimensional information fusion technology, and establishing the fine velocity structure model of the crust and mantle layer medium of the Tibetan Plateau, are the future research direction.
