Title: Zircon U-Pb ages of the early Permian magmatic rocks in the Tazhong-Bachu region, Tarim basin by LA-ICP-MS
Abstract: A combined study of CL imaging and LA-ICP-MS U-Pb dating was carried out for zircon grains of the magmatic rocks in the Tazhong-Bachu region from the Tarim basin, Western China. The results of the systematic zircon LA-ICP-MS U-Pb dating reveal 275 +/- 13Ma for the basalt, 291 +/- 10Ma for the tuff, 274 +/- 15Ma for the gabbro, 272 +/- 6Ma for the diabase, 282 +/- 3Ma for the syenite and 286 +/- 4Ma for the dacite-porphyry, respectively. It indicated that the magmatic rocks of the Tazhong-Bachu region were formed during early Permian.
