In this paper, the U-Pb geochronology of zircon of the 8 samples in Xitian pluton of Hunan Province has been measured. Based on the new data and the latest reported high-precise dating of the related granites, the magmatic activities in the study area can be ascribed to four stages as follows: the first stage of Indosinian (230 ~224 Ma), the peak was about 228 Ma; the second stage of Indosinian was about 215 Ma; the first stage of Yanshanian (160~147 Ma), the peak was about 151 Ma; and the second stage of Yanshanian was after 141 Ma.
