| 摘 要： | 通过高倍显微镜和电子探针波谱对灰家堡金矿矿集区的又一个重要矿床——太平洞金矿的金矿石进行分析,结果表明金主要呈自然矿物相形式存在,主要载金矿物为黄铁矿和毒砂。金粒主要为不规则粒状和尘点状,其次为圆粒状、角粒状和条状等,粒径在14～0.2μm之间,多数在6～0.4μm之间,属微细—次显微金。物相分析显示,硫化物包裹金占86.37%、游离金占6.03%。脉石矿物中的金则以极细状赋存在黄铁矿裂隙中。 |

| Abstract: | Taipingdong gold deposit is one of important gold deposits in Huijiabao gold ore field,Southeastern Guizhou.Research the results of gold occurrence at the deposit show that gold is hosted in pyrite and arsenopyrite.Gold grains are comprised of sub-micrometer to micron size（14～0.2 μm,most at 6～0.4 μm）.Phase analysis indicates that 86.37% of gold are hosted in sulfide and 6.03% of gold are free gold.Gold grains of rocky minerals are in cracks of pyrite. |
| Keywords: | Occurrence Micro-submicrometer Taipingdong gold deposit Xingren County Guizhou Province |
