摘要:
研究区位于著名的班公湖—怒江成矿带上的扎普—多不杂 Fe‐Cu‐Au 成矿亚带内,大地构造位于班—怒结合带北侧,成矿地质条件极为有利,但地质工作程度却较低。本文在1∶50000区域地质矿产调查工作成果的基础上,论述新发现的阿汝村东剪切带型铜金矿的地质特征及意义。结果表明,该铜金矿的成矿地质条件较好,共9条达工业品位的铜金矿体,伴生有用组份主要为 Ag 、Pb 、Zn ,矿体主要赋存于燕山期韧性剪切带中。该铜金矿的发现,对该地区剪切带型铜金矿的研究与找矿具有参考价值。
Abstract:
The studied area is located within the Zhapug‐Duobuza Fe‐Cu‐Au metallogenic sub‐belt of the Bangong lake‐Nujiang metallogenic belt ,and tectonically in the northern side of the Bangong lake‐Nu‐jiang joint belt .This area is endowed with preferential conditions for mineralization but is poorly exploi‐ted .On the basis of the results of 1 :50000 regional geological survey ,this study discusses the geological characteristics and significance of the new found shear zone type copper‐gold mine in eastern Aru Village , Rutog County ,Tibet .The result shows that the copper‐gold deposit with good metallogenic conditions hosts nine industrial‐grade copper gold orebodies with the associated useful components such as Ag ,Pb and Zn .The orebodies occur mainly in the Yanshanian ductile shear zone .The discovery of the copper‐gold deposit has important significance for studying and exploring shear zone type copper‐gold deposits in this area .
