Abstract:Based on recent results of S-wave seismic tomography, we analyze of overall features of the mantle S-wave velocity structures beneath Asia, which correlate with the current movement pattern of mantle heat-flows. The study concludes that the S-wave velocity structure features of the Upper Mantle can be explained by the plate tectonics. Heat accumulation occurs beneath the lithosphere of the central Eurasia superplate. A strong negative velocity disturbance exists in the mantle below Hainan Island and South China Sea that looks very much like a mantle superplume. The movement of mantle heat-fluid flows shows two different geometrical patterns: vertically growing up or side turning. The flows belonging to these two patterns are equally important and can across into each other to construct more complicate modes.
