摘　　要：哈尔汗(督冷沟)铜-钴矿床位于东昆仑多金属成矿带东段。该矿床地质工作及研究程度极低,铜钴矿体明显受万保沟群基性火山岩层位及断裂构造控制。根据矿床地质特征及同位素特征分析,认为该矿床成因为火山喷气-沉积-热液叠加改造复合型矿床,具中-大型远景规模。Haerhan (Dulenggou) Cu & Co deposit is located in the east of Dongkunlun polymetalic mineralization zone. The degree of geological work and research for the deposit is quite low. The ore body is obviously controlled by basic igneous rocks of Wanbaogou group and structural faults. Based on the analysis of geological and isotopic characteristics, the deposit is regarded as a volcanic erupting-depositing-hydrothermal superimposed Cu & Co deposit in a perspective large scale.
