The South China Plate is located on the southeastern margin of the Eurasia Plate, which is composed of the Yangtze Block and the Cathaysia Block. In the Messozoic, massive magmatism and lithospheric thinning have jointly caused the extremely complex structure of the crust-upper mantle, and have formed such metallogenic belts as the middle-lower Yangtze river belt (MLYB), the Qinhang belt, the Wuyi belt and the Nanling belt, and so on. We have studied the velocity model and anisotropic structure beneath South China to discuss the deep geodynamics in the past few years by teleseismic tomography, SKS splitting, ambient noise tomography and teleseismic two-plane-wave tomography, respectively.
