白山市双顶沟岭金矿地质特征及其找矿前景

Geological characteristics and prospecting prospect of Shuangdinggouling gold deposit in Baishan city

利用探槽、坑道、钻孔等探矿手段,共揭露出7条金矿体,矿石类型全部为含金石英脉型。控矿构造为北东向脆性断裂构造,容矿构造为北东向及其次级、派生构造,为浅表脆性断裂构造。结合矿区土壤金元素异常分布情况及区域金矿床(点)特征认为,矿区可能还有蚀变岩型、闪长玢岩型等类型的金矿体,已知矿体深部可能会趋于稳定,总体上矿区找矿前景较大。

A total of 7 gold ore bodies have been exposed by means of prospecting, such as trial trenches, tunnels and drills. The ore types are all of gold-bearing quartz veins. The ore-controlling structure is a brittle fault in the north east direction, and the ore-bearing structure is a brittle fault in the nolth east direction. Combined with the abnormal distribution of soil gold elements and the characteristics of regional gold deposits, it is believed that there may be gold ore bodies in the mining area, such as altered rock type and diorite porphyry type, and the depth of the known ore body may tend to be stable. Generally speaking, the prospecting prospect in mining area is large.
