摘　　要：矿区内出露地层主要为中泥盆统北塔山组第二亚组,为一套海相、海陆交互相的中基性、中酸性火山岩—火山碎屑沉积岩建造。矿区构造较为复杂,为矿液的运移及铜、钼矿质的沉淀、富集提供了良好的空间条件。Sm-Nd等时线年龄测定显示矿床形成于早二叠世,蚀变岩的Rb-Sr全岩年龄测定结果也反映了成矿和该时期发生的热事件有关。索尔库都克铜(钼)矿床成因应该归属于次火山热液层控型铜(钼)矿床。The deposit was preserved in the Beitashan group of the middle Devonian, which occurs within marine-terrigenous facies including a sequence of intermediate-basic volcanic, intermediate-felsic volcanics and pyroclastics. The structure system containing fold and fault provided a comfortable space for the deposition and enrichment of the copper and molybdenum. Dating of Sm-Nd Isochron Ages show that the deposit was formed in the early Permian. In addition, the Rb-Sr dating age of altered rocks also reflects the conclusion. The Suoerkuduke copper deposit should be regard as a stratabound copper deposit related to subvolcanic hydrothermal.
