蒙古国哈茨维奇铜矿位于蒙古南戈壁铜成矿带,分南北2个矿段。矿化主要发育在斑岩体内部,其次在斑岩体与围岩的接触带。矿化受NE向F2、F4两组断裂控制,含矿岩性为花岗闪长斑岩,容矿构造为构造裂隙;围岩蚀变有钾化、硅化、绿泥石化、绿帘石化、青盘岩化,蚀变具斑岩型铜矿蚀变分带特征。矿床成因类型为斑岩型铜矿床。本文从区域地质背景、矿区矿化特征、物、化探成果资料、深部钻探等多元信息综合分析,认为该矿区具有较好的找矿前景。
The Hartsvic copper mine in Mongolia is located in the southern Gobi copper metallogenic belt in Mongolia, with 2 ore blocks in north and south. Mineralization mainly develops inside the porphyry body, followed by the contact zone between the porphyry body and the surrounding rock. The mineralization is controlled by faults NE, F2 and F4. The ore-bearing lithology is granodiorite porphyry and the ore-hosting structure is tectonic fracture. The wall rock alteration includes potassium, silicification, chlorite, Green rock lithology, alteration with porphyry copper alteration zoning characteristics. The type of deposit is porphyry copper deposit. Based on the comprehensive analysis of regional geological background, mineralization characteristics of mineral area, geophysical and geochemical data, deep drilling and other diverse information, it is considered that this mining area has a good prospecting prospect.
