| 摘 要： | 在新疆西准噶尔灰绿山西开展的地球化学剖面上,发现三岔沟金矿点。通过填图、钻探、槽探揭露,发现矿体随脉岩断续产出,品位0.10～13.1 g/t,深部延伸稳定。金矿石组合为黄铁矿、针铁矿、赤铁矿、磁铁矿、褐铁矿、自然金等中低温热液型矿石组合特征。金以自然金、碳酸盐包裹金、硫化物包裹金3种方式存在。将之与邻区金矿成矿特点进行对比,矿体产于泥盆系中酸性脉岩之中,具构造控矿和脉岩控矿双重控矿性。

| Abstract: | The Sanchagou gold deposit was discovered on the geochemical profile of the Huilv mountain in West Junggar, Xinjiang. Through drilling and trenching,the ore body intermittently produced with the vein rock, the grade is 0.10~13.1g/t,the deep extension is stable,Gold ore combination of pyrite, goethite,hematite and magnetite, limonite, natural gold,it shows the characteristics of medium- low temperature hydrothermal ore combination,and the gold exists in three ways: natural gold,carbonatite wrapped gold and sulphide wrapped gold.Compared with the metallogenic characteristics of the neighboring gold deposits,the ore body is produced in the medium-acid vein rock of the Devonian,and has dual ore-controlling properties such as structural ore-control and vein-rock control. |
