Wudang Group is an important part of the South Qinling basement, and therefore the study of its age and structural property is of great significance for understanding the early geological evolution history of the South Qinling belt and its relationship with the Yangtze plate in the Neoproterozoic. At present, the age, division and comparison of Wudang Group are still controversial. In this paper, zircon SHRIMP U-Pb isotope dating was performed on 4 metamorphic acid volcanic rocks from Wudang Group and 1 granite porphyry invading the group in the Xixia-Neixiang-Yunxi area. The age of a sample located at the bottom of Wudang Group in the Xixia-Neixiang area is 802±13 Ma, which can represent the age of the bottom strata of Wudang Group. In addition, 3 volcanic samples collected from the middle-upper part of the group were formed at 725±9 Ma, 732±6 Ma and 725±7 Ma respectively, and meanwhile the age of the granite porphyry is 703±5 Ma. Based on the above results and combined with previous research data on Wudang Group, it is determined that the formation time of Wudang Group is 810~720 Ma, equivalent to the age of Banxi Group of the Yangtze plate, while the Yaolinghe Group between the Wudang Group and the Sinian could be compared with the Nanhua System.
