摘　　要：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。Haciwaqi copper deposit, located in the south Gobi metallogenic zone of Mongolia, is divided into 2 ore blocks as south and north block. Copper mineralization mainly occurred within internal porphyry body and contact zone between rock body and wall rock secondly, which is controlled by 2 series NE-striking faults of F2 and F4. Ore-bearing lithology is granite diorite porphyry, host structure is structural fracture, and alterations of country include potassic alteration, silicification, chloritization and propylitization, with the typical alteration zoning of porphyry copper. Through analyzing regional geological settings and metallogenic features of mine, and the composite results from geochemical and geophysical exploration, deep drill engineering, it is supposed that there is a potential for prospecting copper in this area.
