Three‐Dimensional Lithospheric $VP/VS$ Structure Beneath Chinese Continent Available to Purchase

$VP$ and $VS$ models have been obtained for the lithosphere of Chinese continent by tomography of body‐wave travel times, surface‐wave data, and joint inversion of surface‐ and body‐wave data. However, the $VP/VS$ ratio model derived directly from them shows unphysical values, indicating internal inconsistency of model resolutions and uncertainties. In this study, we use P‐ and S‐wave first arrival times for phases Pg, Pn, P, Sg, Sn, and S from regional earthquakes at 1294 permanent seismic stations in China and directly invert for a new 3D $VP/VS$ model (USTClitho1.0k). Resolution analysis indicates that the obtained $VP/VS$ ratio model has a 2° horizontal spatial resolution down to 100 km in most of Chinese continent. Overall, there is a good agreement between the crustal $VP/VS$ images and the surface geologic features. The Songliao, Sichuan, and North China basins all show high $VP/VS$ values. In contrast, the Tarim basin exhibits low $VP/VS$ values. The Qilian fold belt, Tibetan Plateau, and the Tanlu fault zone in eastern China exhibit lower $VP/VS$ features. High $VP/VS$ values are present in the middle‐lower crust and uppermost mantle beneath the Tienshan orogenic belt, the Qiangtang block, the Songpan–Ganzi block, and the eastern part of continental China. There are local high $VP/VS$ anomalies in the middle crust beneath some volcanoes such as Datong, Tengchong, and Changbaishan. In addition, the uppermost mantle is generally associated with high $VP/VS$ values. Our $VP/VS$ model is consistent with many other studies and may be useful for future geoscience studies in the China region.
