AbstractThe formation and evolution of the Panzhihua ancient mantle plume have crucial scientific significance and application value for the geotectonic pattern, metal mineral accumulation and continental dynamics research in this region. By studying four in-depth seismic profiles of artificial sources crossing the central part of Panzhihua ancient mantle plume and local geophysical boundary field responses, we propose that: (1) Panzhihua ancient mantle plume has a specific crust-mantle velocity structure; (2) in the central part of the Panzhihua ancient mantle plume, the high-speed bodies are found from the crystalline basement to the crust-mantle boundary, and the crystalline basement and Moho interface uplift locally. There are low-velocity layers with a thickness of more than 10 kilometers in the crust, which are cut by several deep and broad faults; (3) the response of anomalous boundary fields of gravity and magnetic fields constitutes the surface morphology of Panzhihua ancient mantle plume and the trap range of its central part.
