| 摘 要： | 对赤峰西部的红花沟、连花山、索虎沟金矿床的矿物共生组合和金矿物的赋存状态进行了研究，同时对金矿物和寄主硫化物进行了电子探针分析测试。结果表明，从成矿早阶段至晚阶段、从包体金至裂隙金，金矿物的Au／Ag或金成色逐渐降低。总体来讲，金成色高的金矿物，其Fe和Bi含量也高，但不同温度区段形成的金矿物，其局部规律有所不同。对红花沟金矿与银金矿共生的铋硫盐矿物-针硫铋铅矿也进行了详细分析。矿床中富含铋矿物的地方往往也富含金，可作为有意义的找矿标志。

| Abstract: | Research of mineral assemblages,occurrences of gold-bearing minerals in Honghuagou,Lianhuashan and Suohugou gold deposits from western Chifeng of Inner Mongolia and electron microprobe analyses of gold-bearing minerals and host sulfide minerals show that Au/Ag ratios of gold-bearing minerals reduced gradually with mineralization,and the ratios for inclusion gold is higher than those of fissure gold minerals. In general, gold-bearing minerals of high fineness have high contents of iron and bismuth, and the fineness might change with forming temperature of gold-bearing minerals. The analyses of bismuthiferous sulfosalt and aikinite coexisting with electrum in Honghuagou gold deposit show that orebodies rich in bismuth minerals usually rich in gold-bearing minerals,which could be taken as a mark for gold prospecting. |
