The evolution of the South China Sea (SCS) is directly linked to the complex subduction systems of the surrounding Pacific,Philippine Sea and Indo-Australian Plates (Fig.la).Major advances in the last several years are providing new insights into the SCS-mantle dynamics,through regional seismic imaging of the upper mantle [1,2],unprecedented IODP drilling expeditions (349/367/368/368X) [3-5] that obtained the oceanic basement basalt samples for the first time,geochemical analyses of the SCS-mantle source compositions [6-8] and geodynamic modeling [9,10].Furthermore,new geological mapping,seismic imaging [11,12]and IODP drilling [13,14] have revealed evidence for significantly greater magma production at the northe SCS rifted margin,in comparison to the magmapoor end-member of the Atlantic rifted margins.
