英文摘要	We analyzed and discussed the gravity field across the middle Qinling Mountains from Huxian to Zhenba in the synthetical geophysical transect from Yulin in Shaanxi province to Yuquan in Chongqing. For the first time, we obtained the crustal structure, Moho depth and mountain root of the middle Qinling Mountains. Based on our research, several major faults with obvious gravity anomalies are suggested in the interpretation for the structure and tectonics of the crust. They are the fault on north of Qinling, the faults in middle Qinling, Ningshan fault on south of Qinling, Ankang (on the southwest of Shiquan) fault, Bajiaokou fault, the north section of the Chengkou fault, Zhenba fault, Yudu fault and Tiexi fault. In addition, we calculated the directional derivatives of gravity anomalies V-xz and derived the location, size, style and tendency of the faults. At last, we discussed the joint and transition characteristics of crustal structure and fault structure of the middle Qinling from the view of gravity.
