    Abstract: Deep dynamic processes of the evolution of the South China Sea (SCS) are recorded by the large-scale magmatism in the SCS and its surrounding regions. The geochemical analysis of whole-rock and olivine phenocryst was conducted on the Late Cenozoic basaltic rocks, which are exposed in the continental margins of the northern (the Leiqiong Area) and w...
