Abstract
The density structure of the oceanic lithosphere of South China Sea (SCS) is key for understanding how the Hainan Plume affected the opening of the SCS. A lithosphere-scale 3-D density structural model has been constructed. We obtain the 3-D density structure of the sediments and the crust from regional reflection and refraction seismic lines. The temperature and related density structures of the mantle between 50 and 250 km are derived from a shear wave velocity (Vs) tomography model. To assess the density between the Moho and 50-km depth, we combine forward and inverse 3-D gravity modeling…
