Broad-band Seismic Study of the Crustal and Upper Mantle Structure in the Eastern South China Block
      South China is one of the most geologically complex areas in eastern Asia, as it has undergone a long-period of crustal accretion and tectonic deformation since the Neo-Proterozoic. In addition, it has abundant magmatism activities and mineralization. To reveal the geodynamic process, mechanism of the sub-surface deformation, and the accompanying magmatism activities and mineralization, we needed more detailed information on the architecture and medium properties of the crust, lithosphere, and upper mantle. A broad-band seismic study could provide abundant information on the crust and upper mantle. In this study, we summarized the broad-band seismic data acquisitions in the eastern South China Block in the past 2 decades and reported the latest data on the crustal thickness, crustal Vp/Vs ratio, LAB depth, velocity structure, and anisotropy of the upper mantle. This study can not only provide references for future data acquisition but also some basic information for the study of the deep structure, geodynamics, and mineralization in this area.
