摘要
根据老厂环形影象特征、大地构造背景及区域地质构造环境分析,岩浆岩脉的发现和田岩蚀变,地球化学及同位素地质特征等对老厂银铅矿区深部存在隐伏岩体进行了预测。老厂银铅矿床不是火山岩矿床,而是与地洼期隐伏岩体有关的中偏高温热液多因复成矿床,并预测于矿区深部可望找到新的金铜矿床类型的矿体。
Based on the characteristies of ring images, the geotectonics and regional geological analysis, the veins distribution, the wallrock alternations and the study of geochemistry and isotope geology, it is inferred that there is a concealed granitic body of the depth in the mining region. Therefore, it is suggested that the deposit is not a volcanic-origin Ag-Pb deposit , but a middle-hightemperature polygenetic compound one related to concealed diwa-period magmatic activities. A new Au-Cu type deposit is hypothesized to occur at depth in the mining district.
