| 摘 要： | 大田坵地银多金属矿位于大田一雄峰北北东向复式向斜褶皱的东北段，区内断裂构造发育，多期次断裂构造活动为成矿物质充填、交代富集提供有利条件。矿体产于早三叠世溪口组中的北东-北北东向断裂带内，呈透镜状产出。容矿岩石为绿帘石角岩、角岩化钙硅质粉砂岩。通过对区域地质背景及矿床地质特征综合分析，认为该矿床属热液充填-交代型。

| Abstract: | Qiudi silver polymetallic deposit deposit in the norhteast section of Datian-xiongfeng NNE duplex syncinal fold. Development of fault structures in the region, multi-stage fault activities offer favorable term for the ore filled and metasomatic enrichment. The orebody deposit in the NE-NNE fault zone of the early Triassic Xikou formation and acts like a lentic- ular occurrence. Ore-bearing rocks are epidote-Shek Kok rock and hornfels calcium siliceous siltstones. Through comprehensive analysis of regional geological setting and geological fea- tures, it is considered that the deposit belongs to the hydrothermal filling metasomatic type. |
