研究金矿矿石中不同成矿阶段载金矿物,有利于金矿的开发利用。采用电子探针对陕西后林沟金的赋存状态研究,确定褐铁矿、石英和黄铁矿是该地区金矿主要的载金矿物,金矿物多赋存于褐铁矿和石英中,以粒间金、裂隙金和少量包体金形式存在。可以得出硅化、褐铁矿化、黄铁矿化共存是该地区找矿的直接标志。
Studying gold-bearing minerals in different metallogenic stages of gold ore is beneficial to the development and utilization of gold ore. Using electron probe to study the occurrence of Houlingou gold in Shaanxi Province, it is confirmed that limonite, quartz and pyrite are the main gold-bearing minerals in the gold deposits in the area, and the gold minerals are mostly found in limonite and quartz, Intergranular gold, fissure gold and a small amount of gold in the form of inclusions exist. It can be concluded that silicification, limonite mineralization and pyrite mineralization are the direct signs of prospecting in the area.
