| 摘 要： | 金平铜厂铜钼矿床赋矿岩体位于哀牢山-金沙江新生代成矿带南端,红河走滑断裂西侧,赋矿岩体主要由二长花岗斑岩及二长花岗岩组成。岩体锆石阴极发光图(CL)环带构造发育,不同环带U-Pb年龄在误差范围内基本一致。锆石LA-ICP-MS U-Pb年结果表明赋矿岩体主要是35.1±0.3Ma形成的。含矿岩体形成与印度板块与欧亚板块碰撞产生的红河-哀牢山左行走滑断裂活动有关。

| Abstract: | The Jinping-Tongchang Cu-Mo deposit located at the southwestern segment of the Ailao Shan-Red River shear zone,which is in the southern part of the Cenozoic metallogenic belt along the Ailao Shan-Red River shear and its northern stretching zone in eastern Tibet. The Jinping-Tongchang ore-bearing porphyry is composed of monzogranite porphyries and monzonites. CL photos of the analyzed zircons from the Jinping-Tongchang porphyry are characterized by the well-developed oscillatory zoning,suggesting that the an... |
