黑龙江金厂金矿床土壤地球化学找矿标志研究

Study on the prospecting indicators of soil geochemistry of Jinchang gold deposit in Heilongjiang province

金厂金矿床为一以爆破角砾岩筒型矿化为主体的特大型岩金矿床。根据黑瞎子沟矿段2条土壤地球化学剖面研究结果,对该区土壤地球化学找矿标志进行了初步分析和讨论,提出Au、Cu、Hg高值组合异常是寻找隐伏矿体的主要土壤地球化学元素组合标志的认识,这对该区进一步找矿工作有一定的指导意义。

Jinchang gold deposit is a super large primary gold deposit dominated by explosive breccia pipe type mineralization.Based on the study on soil geochemistry of two cross sections in Heixiazigou ore section,the prospecting indicators of soil geochemistry were preliminarily discussed and analyzed.The conclusion was made that high value anomolies of Au,Cu and Hg combination is the primary prospecting indicators of soil geochemistry for buried orebodies,which can instruct the progressive exploration work in the mining district.
