LA-ICP-MS zircon U-Pb ages of granite in Paoshuiling of Limu indicate that the Paoshuiling granite was produced by Indosinian magmatism and probably formed in three stages of magmatic activities, which occurred at 210Ma, 222Ma and 239Ma respectively. Combined with the latest research, the authors hold that Limu granite was formed in Indosinian period and the magmatic activities were concentrated between 210Ma±4Ma and 222Ma±5Ma. In addition, the age of 239.8Ma±4.3Ma might represent the early Indosinian magmatic activity.
