Zircon U-Pb ages of three meta-acidic volcanic rocks from the Wudangshan Group, Southern Qinling Mountains, Central China, dated by means of LA-MC-ICPMS are reported in this paper. The dating results show that the age of the meta-acidic volcanic rock is 675.2 ± 3.1 Ma (MSWD = 3.7), which constrains that the Wudangshan Group contains Nanhuan (Cryogenian) Period components. The Wudangshan Group is mainly composed of volcanic rocks of various ages and minor sedimentary rocks, demonstrating complex deformation and metamorphism and including poly-phases of magmatic rocks. Some meta-acidic volcanic rocks in the Wudangshan Group have similar age with the volcanic rock in the Yaolinghe Group and the basic intrusive rocks in the Wudangshan Group, indicating possible genetic relationship between the acidic volcanic rocks with the basic intrusive rocks in the Wudangshan Group and the Yaolinghe Group volcanic rock. Based on the available isotopic dating, it seems that the age span of the Wudangshan Group extends from the Archean to the Mesozoic, but the general trend is that most of the recently acquired age data are younger than those obtained earlier.
