摘　　要：在总结绿源金矿成矿地质特征基础上,结合电子探针分析结果,对绿源金矿主要载金矿物中金的赋存状态进行探讨。绿源金矿主要载金矿物为含砷黄铁矿、毒砂及黄铜矿,金主要以不可见金的形式存在,含砷黄铁矿中金主要以纳米级自然金形式存在,极少量以固溶体或离子金形式存在。据绿源金矿主要载金矿物黄铁矿中Co,Ni含量及Co/Ni比值,推测黄铁矿为热液矿床成因或火山成因。据绿源金矿典型叶片状方解石及胶状石英等地质特征,认为绿源金矿为低硫型浅成低温热液型金矿床。Based on the summary of the geological characteristics of Lvyuan gold deposit,combined with the electronic probe analysis,this paper diccussed the gold occurrence in gold bearing minerals of Lvyuan gold deposit.The gold bearing minerals mainly are arsenopyrite and arsenian pyrite,and Au mainly exists in the form of invisible gold.The Au in arsenic pyrite is mainly nano natural gold（Au0） with a very small amount of solid solution or gold ion（Au＋）. According to the Co,Ni content and Co/Ni ratios of pyrite,we infer that the pyrites was the pruduct of hydrothermal or volcano.Combined with the exist of the typical leaf like calcite and colloidal quartz,this paper thinks that the genetic type of Lüyuan gold deposit is low sulfur-epithermal type gold deposit.
