In the present study, 3-D high resolution S wave velocity tomography by 1°×1° cells have been performed within the limits of crust and upper mantle from by using surface wave dispersion inversions,through collecting 1500 three components long-period digital seismic records from 187 representative events recorded by 44 seismic network stations which over Asia, part Europe and the west Pacific Ocean areas from 1986 to 2001, picking out 390 accurate surface wave dispersion cures which great circle path nearly cover Tibetan plateau. According to the tomography rsults about S wave velocity, crust thickness of Tibetan plateau has been detected. This paper discusses the structure evolution and dynamics feature of Tibetan plateau.
