| 摘 要： | 本文对新疆巴里坤红石滩铜矿区出露的石英闪长斑岩进行LA-ICP MS锆石U-Pb年龄测定,结果表明红石滩石英闪长斑岩形成年龄为403.1±3.8 Ma,形成时代为早泥盆世.此外,测得的两个锆石U-Pb同位素年龄为895 Ma左右,表明研究区可能存在早元古代基底.红石滩石英闪长斑岩体与铜矿关系密切,是寻找斑岩型铜多金属矿的有利场所,为今后在该区寻找同类型铜矿提供重要依据.

| Abstract: | The quartz diorite porphyries from the Hongshitan copper deposit, Balikun county, Xin- jiang, were dated using LA-ICP-MS zircon U-Pb dating . The results indicate that the Hongshitan quartz diorite porphyries yield an age of 403. 1±3.8Ma, belonging to early Devonian. In addition, two zircon grains yield U-Ph isotope ages about 895 Ma, indicating the existence of the early Proterozoic basement in this area. The Hongshitan quartz diorite porphyries show a close relationship with mineralization of porphyry copper, and the area of Hongshitan is a favorable place for prospecting porphyry copper-polymetallic deposits. It can provide an important basis for prospecting the same type copper deposits in this area. |
