摘要
新疆卡特巴阿苏金矿床是那拉提-红柳河金-铜-镍-铅锌-玉石-白云母成矿带内近几年发现的特大型金矿之一。在野外地质调查和室内综合整理基础上，利用显微镜鉴定、扫描电镜观察和X射线能谱仪测试分析等手段和方法，对金矿石中金的赋存状态进行了研究。结果表明，卡特巴阿苏金矿床金矿物主要以自然金和含银自然金的形式存在，自然金成色为764.5‰～1 000‰；主要载金矿物为黄铁矿，有少量黄铜矿及脉石矿物；金的嵌布类型有裂缝金、晶间金和相对较少的包裹金3种形式；矿石中自然金均为粒度小于40 μm的显微粒金。
The Katebaasu gold deposit is one of the superlarge gold deposits recently discovered in the Nalati-Hongliuhe gold-copper-nickel-lead and zinc-jade-muscovite ore-forming belt. Based on field geological survey and indoor integrated study, the authors investigated the modes of occurrence of gold in the gold ore by such means as microscope identification, scanning electron microscopy and X-ray energy spectrum analysis. The results show that gold minerals in the Katebaasu gold deposit mainly occur as native gold and silver-bearing native gold, with the fineness of the native gold being 764.5‰~1 000‰. The main gold-carrying mineral is pyrite, with a small amount of chalcopyrite and gangue minerals. The main gold mosaic forms include crack gold, intercrystalline gold and minor enclave gold. In the ore, native gold exclusively exhibits microscopic grained gold with the grain size less than 40 μm.
