 The South China block was formed through collision between two tectonic plates, resulting in the removal of part of its lithospheric route. However, the exact mechanism behind this process remains unclear. Using a new joint seismic inversion algorithm, researchers were able to identify tabular high-velocity anomalies in the Aspenosphere beneath the South China block. These anomalies are interpreted as partially destabilized lower lithosphere that originally delaminated from the stable Yangtze lithosphere at around 180-170 million years ago, before being relocated back to their original positions due to heating in the mantle. This process is believed to have caused lithospheric extension and extensive melting of the overlying crust, leading to the formation of a mesozoic basin and rain-style magmatic province in South China.
