| 摘 要： | 水银洞金矿上二叠统龙潭组一段(P_3l~1)中矿体主要为生产探矿中新发现,地质勘探中未发现该类金矿体的大规模存在;主要以构造控制的白云石石英脉粉砂质粘土岩型为主,灰岩类及白云石化钙质砂岩类含金矿体为辅,白云石石英脉粘土岩型矿体是以品位高、厚度薄、稳定为特征,该矿体受灰家堡背斜轴附近的东西走向隐伏逆冲断层控制,主要分布于F_(301)断层上下盘,含金热液沿东西走向隐伏逆冲断层向上运移(刘建中.2003)、再向有利的层间滑动及北东向陡倾斜次级隐伏逆冲断裂构造富集成矿,东西走向隐伏逆冲断层是导矿构造又是容矿构造,其上盘层间白云石英脉为明显找矿标志,对灰家堡背斜深部找矿及和生产具有一定的指导有意义。

| Abstract: | The orebody in Longtan formaTion of upper Permian mainly is new found in the production ane exploration in Shuiyindong gold deposit,big scale gold orebody of this kind has not been found in geological exploration,mainly is dolomite quartz vein silty clay rock which is controlled by structure,with limestone and dolomite calcareous sandstone gold-bearing orebody,the dolomite quartz vein silty clay rock has characteristics of high grade,thin thickness and stability,this orebody is controlled by EW concealed trust fault near the Huijiabao anticline axis,mainly distribute in the upper and lower plate of F301 fault,gold-bearing hydrotherm upward migrate along EW concealed trust fault,then slip and concentration in ore-formation to advanced layer and NE steeply dipping secondary concealed trust fault,EW concealed trust fault is ore passage and ore hosting structure,the dolomite quartz vein in the upper plate is the signal for exploration,it will afford some guidance for deep exploration and production in Huijiabao anticline. |
