Based on the detection profiles of Hi-CLIMB broadband digital stations in the central Tibetan Plateau, the detection profiles are transformed into two-dimensional velocity structure profiles, and then compared with the CCP results. The inversion results clearly show the S-wave velocity structure in crust and a velocity jump across the Moho discontinuity in the region. The results reveal that the average thickness of the crust is 75 km from N29.4° to N31.5° and 65 km northward from N32°. The interfaces dipnorthward in the south of N31.5°, but in the north the structure is exactly inverse. The authors also find a marked slow-velocity zone in crust beneath YZS and BNS. This complex structure suggests that there exist strong compressional deformation and material exchange in the region.
