| 摘要: |
| 羊拉铜矿床的构造混杂岩由几个不同时代、不同岩性组合的构造岩片组成,主要矿体局限在二叠系构造岩片中,二叠纪的构造混杂形成矿区的叠瓦式构造。燕山晚期-喜马拉雅期的构造活动表现为矿区内的左行走滑断层、斑岩侵入,并伴生铜钼矿化。 |

| Abstract: |
| The tectonic mélanges in the Yagra copper deposit in Deqen, Yunnan consist of a series of tectonic slices that differ in age and composition. The Yagra copper deposit is mostly hosted to the Permian tectonic slices, which constitute the imbricate structures in the mining district. The late Yanshanian-Himalayan (tectonism) is manifested in the sinistral strike-slip faulting and porphyry emplacement, accompanied by copper and molybdenum mineralization. |
