摘　　要：陕西旬阳老君庙金矿为近年来新发现的微细浸染型金矿。通过对金矿石中金的赋存状态进行研究,金主要以超显微包裹的纳米金形式存在,金的赋存状态主要以硫化物(黄铁矿)中的金为主(45%)、次为石英、硅酸盐矿物(硅质碎屑、砾石)中的金(29.51%)、自然金(17.65%)及碳酸盐矿物(方解石)中金(7.84%),主要载金矿物为黄铁矿[1]。The Laojunmiao gold mine in Xunyang,Shaanxi Province represents a recent discovery of a microdisseminated gold mine.The occurrence state of gold in gold ore was studied,and it was found that gold mainly exists in the form of ultra-microcoscopically encapsulated nano-gold.The occurrence state of gold is mainly gold in sulfide(pyrite)(45%),followed by gold(29.51%)in quartz,silicate minerals(siliceous clasts,gravel),natural gold(17.65%),gold in carbonate minerals(calcite)(7.84%),and the main gold-bearing mineral is pyrite.
