额济纳旗黄山铜矿地质特征及找矿线索分析

Geological Characteristics and Prospecting Clues in the Huangshan Copper Deposit of Ejina County,Inner Mongolia

额济纳旗黄山铜矿位于内蒙古北山额济纳-雅干华力西期铁、金、铜、钼、镍成矿带的石板井-东七一山钨、钼、铜、铁、萤石成矿亚带,成矿条件优越。对矿区地质特征及物化探异常特征的分析显示,矿体空间分布套合较好,矿化与志留系公婆泉组关系密切,矿体空间展布受北西向逆断层控制。前期工程验证工作投入较少,尚未能揭露原生矿体,后续勘查工作应加大深部工程力度,尽快寻找到原生主矿体,为本区大比例尺勘查工作提供支持。

The Ejinaqi Huangshan copper deposit of Inner Mongolia is located in the Beishan Ejina - Yaganhualixi iron, gold, copper, molybdenum, nickel metallogenic belt Ishi Sakai, the Dongqiyishan tungsten, molybdenum, copper, iron, fluorite mineralization sub - belt, with favorable metallogenic conditions. Analysis of geological features and geophysical and geochemical anomalies in this area shows a good matching of ore - body spatial distribution. The mineralization is closely related with the Gongpoquan Formation of Silurian. The spatial distribution of ore bodies is controlled by the NW - trending reverse faults. Because engineering investment in the previous work is less, primary ore bodies in the deposit have not been well revealed. The following survey work should make more efforts in deep exploration so as to figure out main ore bodies as soon as possible, which can provide support the large - scale exploration in this area.
