摘　　要：哈赞布拉克金铜矿位于博罗科努金铜钼铅锌成矿带。矿化产于华力西中期中酸性侵入岩体内及与围岩接触带内,主要蚀变为围岩地层中的角岩化,闪长岩中的钾化、绢云母化、青盤岩化及含矿岩石中的硅化、碳酸盐化等,矿区发现Ⅰ、Ⅱ、Ⅲ号三个矿化带,以Ⅱ号矿化带规模最大,矿床为铜、金共生矿化,矿化成因类型为石英脉型、矽卡岩型、斑岩型,以石英脉型矿化为主,矿化主要受岩浆岩和构造控制,矿床为先期斑岩型矿化,伴矽卡岩型矿化,经后期热液改造叠加的石英脉型矿床。The Hazanbulake gold and copper deposit is located in Boluokenu gold, copper, molybdenum, lead and zinc ore forming belt. The mineralization occurs in intermediate acid intrusions and its contact with coun- try rocks. The major alterations are hornfelsed alteration in the strata, potassic alteration, sericitization, silicification, carbonification in ore bearing rocks, I , II , Ⅲ mineralization zones have been found in the mine with the II as the largest one, the deposit is copper and gold paragenetic minimization and the genetic types of mineralization are mainly quartz vein type, skarn type and porphyry type with quartz vein as main mineralization, and controlled by magmatic rocks and structures. The deposits are early stage porphyry mineralization, associated skarn type mineralization superimposed at late stage hydrothermally transformed quartz vein deposit.
