通过矿相鉴定、单矿物含金分析、物相分析对皖西南枞阳井边金矿金的赋存状态进行了系统研究 ,并用微束分析技术———质子探针分析方法对超显微形式存在金的赋存状态进行研究 .结果表明 :矿石矿物黄铁矿、黄铜矿中金的赋存状态以微细粒自然金为主 ,其次为银金矿 .金有 2种形式存在 ,一种是显微可见金 ,另一种是超显微形式存在的金 ,其中 ,显微可见金又进一步分为包裹金和裂隙金 ;超显微形式的金也是一种游离金 ,而不是晶格金 ,这与我国卡林型金矿床中金的赋存状态一致 The occurrence status of gold in Zongyang Weidebian gold deposit in southwestern Anhui Province was studied systematically through the identification of mineralogical phases, single-mineral gold-bearing analysis and phase analysis. The microscopic analysis of proton microprobe analysis The results show that the gold deposits in the ore minerals pyrite and chalcopyrite are dominated by fine-grained natural gold, followed by silver-gold deposit, there are two forms of gold, one The species is microscopically visible and the other is gold in the supermicroscopic form, in which gold is further subdivided into encapsulated gold and fissured gold; the microscopic form of gold is also a free gold, not a crystalline This is consistent with the state of gold in the Carlin-type gold deposit in our country
