| 摘要: |
| 泥堡金矿具多层含矿特征,各层金矿体均与二叠系火山碎屑岩密切相关。根据对矿床地质、地球化学、流体包裹体等多方面研究认为,火山碎屑岩与大厂石英岩之间的假整合面是最主要的容矿空间;金矿的成矿时代为晚侏罗世,金矿的形成与峨眉山地幔柱残留部分在燕山期的活动有关。 |

| Abstract: |
| The Nibao gold deposit in Guizhou consists of multistory gold ore bodies,each of which is closely associated with the Permian volcaniclastic rocks.The examination of geology,geochemistry and fluid inclusions from the gold deposit has disclosed that the pseudoconformity between the volcaniclastic rocks and Dachang quartzite occurs as the main accommodation spaces. The gold mineralization age can be traced back to the Late Jurassic.The formation of the gold deposit is interpreted to be related to the local reactivation of the residual parts of the Emei mantle plume during the Yanshanian. |
