青海省当江铜多金属矿地质特征及成矿远景分析

Analyses of Geological Characteristics and Metallogenic Prospect if copper-polymetallic Deposit in Dangjiang Township of Qinghai Province

当江铜多金属矿矿区位于青海省治多县当江乡境内。通过对区域内赵卡隆铁多金属矿床、尕龙格玛铜多金属矿床的对比,二者具有相同的成矿时期,相同的含矿地层,相同的蚀变矿物等,认为当江铜多金属矿床成因属于海相火山岩的火山喷流沉积型铜多金属矿床。

Dangjiang Copper Polymetallic Mine is located in dangjiang Township,Zhiduo County,Qinghai Province.Through the comparison of Zhaokalong iron polymetallic deposit and galonggema copper polymetallic deposit in the region,they have the same metallogenic period,the same ore bearing strata and the same altered minerals.It is considered that the genesis of dangjiang copper polymetallic deposit belongs to volcanic exhalative sedimentary copper polymetallic deposit of marine volcanic rocks.
