摘　　要：应用电子探针、电子衍射、电子顺磁共振和化学分析等多种现代方法和手段，综合研究载金矿物的特征及金的赋存状态，认为金牙金矿中载金矿物主要是毒砂和黄铁矿，金的主要赋存形式是超显微包体金，为解决金牙金矿床难处理的原生矿石提供了科学数据资料。In order to resove the problems in ore dressing and smelting from the primary ores of the Jinya gold deposit, studies of the characteristics of the gold carrying minerals and the occurring state of gold were undertaken. Based upon comprehensive studies by some new methods such as electron microprobe, electron diffraction, electron paramagnetic resonance and chemical analysis, it is considered that the gold carrying minerals were mainly arsenopyrite and pyrite, that gold was mainly occurred as supermicro grain gold inclusion.
