Modes of occurrence of gold in the Xindigou gold deposit, Inner Mongolia
-
摘要: 内蒙古新地沟金矿床为一典型绿岩型金矿。利用显微镜、扫描电子显微镜观察到自然金602粒。研究表明,金的赋存形式主要有包体金、裂隙金、粒间金和连生金。载金矿物以黄铁矿、石英为主,所占比例达到95%;其次是钾长石、绢云母、菱铁矿、褐铁矿、黝铜矿、方铅矿、闪锌矿等。自然金的粒度主要以显微极微粒金(0.2~5 μm)、显微细粒金(10~20 μm)、显微中粒金(20~50 μm)、显微微粒金(5~10 μm)为主,分别占32.23%、26.91%、20.6%、16.11%;手标本及显微镜下也能观察到显微粗粒金(50~100 μm)和巨粒金(100~200 μm),虽然其含量仅占4.15%,但其面积可达33.97%,对于矿石品位和储量来说十分重要。电子探针和物相分析显示,矿石中金主要以独立矿物存在,包括大量的自然金和少量的银金矿;通过计算表明金的平均成色为803,金矿物的成色和特征反映金矿形成条件为中温和中等深度。Abstract: The Xindigou gold deposit in Inner Mongolia is a typical greenstone belt gold deposit. Microscope and scanning electron microscope were used to study the modes of occurrence of gold. 602 grains of native gold were recognized, including inclusion, fissure-filling, and intergranular and interlocking gold. The gold-hosting minerals are mainly pyrite and quartz, which account for 95% of the total gold-hosting minerals, and minor K-feldspar, sericite, siderite, limonite, tetrahedrite, sphalerite, galena were also identified. On the basis of statistics, the gold granularity is mainly characterized by micro extra particulate (0.2-5 μm), micro fine particulate (10-20 μm), microscopic medium (20-50 μm), and micro particulate (5-10 μm) grained gold, accounting for 32.23%, 26.91%, 20.6%, and 16.11%, respectively. The micro coarse-gained gold which was observed in the sample and under the microscope is relatively minor but plays an important role in the ore grade and total resource. Electron microprobe analysis and phase analysis show that gold occurs mainly as independent gold minerals. The gold minerals are mainly native gold and secondary electrum (the average fineness is 803), which indicates that gold was formed under the condition of medium temperature and depth.
