摘　　要：穆龙套金矿床位于中亚成矿域南天山成矿域西段、卡拉库姆和中哈萨克斯坦-北天山板块的碰撞带上,赋矿围岩为寒武—奥陶纪别索潘组,金矿成矿时代主要为二叠纪.通过研究穆龙套金矿床区域构造演化及构造、岩浆控矿作用,提出穆龙套金矿床控矿因素为NWW向桑格龙套-塔姆德套剪切带及NE向穆龙套-道古兹套剪切带,岩浆活动与成矿密切相关.中亚成矿域新疆境内穆龙套式金矿找矿方向是NWW向与NE向构造的交汇处及附近同成矿期隐伏或出露的花岗质岩浆岩.Muruntau gold deposit lies at the collision belt,which is located in the west part of southern Tianshan mountains metallogenic belts belonging to central Asia metallogenic domain,between Karakum Plate and the central Kazakhstan-North Tien Shan Plate.The surrounding rock of Muruntau gold deposit belongs to Cambrian to Ordocician Besopan Suite,and the gold ore formation age is Permain when the south Tianshan ocean consumed.The method used in the study was structural evolution,structural and magmatic control of Muruntau gold deposit,and it has been showed that controlling factors were NWW Sangruntau-Tamdytau shear zone and NE Muruntau-Daugyztau shear zone and gold mineralization had close relationship with magmatism.The exploration of Muruntau type gold deposit is the intersection of NWW Sangruntau-Tamdytau shear zone and NE Muruntau-Daugyztau shear zone,and in the vicinity of blind or crop out granitic intrusion is metallogenic epoch.
