青海省兴海县在日沟铜铅多金属矿成因分析

Causation Analysis of Copper Lead Polymetallic Mine in Xinghai County, Qinghai Province

在日沟铜铅多金属矿地表矿体均产于上三叠统陆相火山岩中,受断裂构造、火山构造控制明显,Cu、Mo、W、Sn、Pb、Zn、Ag等元素在平面上具明显的分带性,深部矿体在火山岩中、变质杂岩体中均有发育。通过对矿区内地层、构造特征、岩浆活动、矿化蚀变等现象以及多年的找矿成果分析,矿床类型为斑岩型矿床,具有良好的找矿前景。

The surface orebodies of copper and lead polymetallic ore in the day trench are all produced in the continental volcanic rocks of the Upper Triassic, and controlled by fault and volcanic structures Visibility. Cu, Mo, W, Sn, Pb, Zn and Ag are divided in plane and the deep orebodies are developed in volcanic rocks and Metamorphic rocks. Based on the analysis of strata, tectonic features, magmatic activity, mineralization alteration and ore prospecting results in the mining area, the type of deposit is Porphyry type and there is a fine prospect of ore prospecting, .
