| 摘 要： | Introduction The three-dimensional S wave velocity of Chinese mainland and its neighboring region in-verted by surface wave dispersion data plays an important role in studying the lateral variation of lithosphere and geodynamic process, and understanding the forming and evolution of Chinese mainland and the relationship between shallow and deep structures. The three-dimensional veloc-ity structures of China and its major tectonic blocks were respectively studied by SONG, et al (1993), ZHOU…

| Abstract: | The three dimensional S wave velocity structure of the crust and upper mantle of Chinese mainland and its neighboring region is obtained by genetic algorithm of surface wave tomography, with smoothness constraint, based on 25 wave group velocities for the periods from 10 s to 92 s, measured from long period Rayleigh waves recorded by 11 stations of CDSN and 12 digital seismometers surrounding China. The S wave velocity image is shown on two latitudinal sections along 30N and 38N, two longitudinal sections along 90E and 120E, and four horizontal slices at the different depths. |
