摘要
从江那哥铅锌矿为铜、铅锌多金属矿床,矿体产出严格受构造控制,区域上南北向的宰便断层为该矿床的导矿断层,近东西向的尾洞溪断层为容矿断层,矿体呈透镜状、网脉状产于尾洞溪断层带中,矿化较好的地段主要为尾洞溪断层与下江群甲路组中上部相切的地段,并且在矿体部位蚀变较为强烈,距离辉绿岩体相对较近处金属含量相对较高,形成了明显的分带性;本文在对成矿规律探讨的基础上提出了进一步找矿的方向。
The Congjiang-Nage Pb-Zn deposit is a Cu-Pb-Zn polymetallic Sulfide ore Deposit,strictly controlling ore output by structure,The area of the north-south Zaibian fault for the guidance of ore deposits and east-west Weidongxi fault for loading of ore deposit,for the lens,nets pulse shape from Weidongxi fault belt,mineralization mainly for good location with a XiaJiang-Jialu group the tangent of the ore district,and in the area are strongly ore altered,relatively close metal content is relative taller,formed the obvious zoning.On the basis of discussing metallogenic regularity,for ore prospecting,the direction of prospecting was proposed.
