摘要
滴水山金矿位于北祁连加里东褶皱带西北边缘,矿床受控于近EW向展布的韧性剪切带中,并与NE向的阿尔金断裂组成"λ"字型构造。通过岩屑测量共圈定12个化探综合异常,其中AR1、AR2和Au8化探综合异常走向呈近EW向,元素组合为Au、Ag、Cu、Pb、As、Sb、Hg等,各元素异常衬度和规模较大,且分带明显,具有较好的找矿前景。经后期工程揭露,发现了有价值的金矿体,总结了找矿方法和找矿标志。根据矿床地质特征认为该矿床为火山岩区脆-韧性剪切带型构造蚀变岩型金矿床。
Dishuishan gold mine is located in North Qilian Caledonian fold belt northwest edge, controlled by EW trending ductile shear zones, and the North East to the Altun fault composition λ shaped configuration. Delineated by a total of 12 cuttings measuring comprehensive geochemical anomaly, which AR1, AR2 and Au8 comprehensive geochemical anomaly trend was EW, combinations of elements for Au, Ag, Cu, Pb, As, Sb, Hg, etc., each element anomalies greater contrast and size, and the zonation obviously has good exploration prospects. Late works by exposing find valuable ore bodies, summarizes the prospecting methods and prospecting mark. According to the geological characteristics of the deposit area believe that the deposit is a volcanic brittle-ductile shear zone structure altered rock type gold deposit.
