| 摘 要： | Introduction Shanxi uplift area is bounded by Ordos block to the west, Taihang Mountain front fault zone to the east. On the north side, it is also adjoined with Yinshan fold belt and Hetao-Baotou fault depression basin accompanied with its southern active ruptures, as well as on the south side, connected to Weihe fault depression basin accompanied with large ruptures on the northern margin of Qinling fold belt. The interior of the Shanxi uplift area, with complicated tectonic structures, … |

| Abstract: | Based on S wave records of deep teleseisms on Digital Seismic Network of Shanxi Province, shear wave velocity structures beneath 6 stations were obtained by means of S wave waveform fitting. The result shows that the crust is thick in the studied region, reaching 40 km in thickness under 4 stations. The crust all alternatives high velocity layer with low velocity one. There appear varied velocity structures for different stations, and the stations around the same tectonic region exhibit similar structure characteristics. Combined with dominant depth distribution of many small-moderate earthquakes, the correlation between seismogenic layers and crustal structures of high and low velocity layers has been discussed. |
