摘　　要：索尔库都克铜矿区具较好的找矿前景,开展索尔库都克铜矿矿床成因分析工作十分必要。硫同位素样品显示以岩浆硫为主;稀土元素特征反映含矿溶液改造安山质岩石的特征;氢、氧、碳同位素特征推测本矿床具有与辉石闪长岩有关的热液迭加交代的特征;矿物包体测温成果显示符合一般矽卡岩矿床的温度变化规律。综合上述矿床成因的多种信息,分析得索尔库都克铜矿矿床成因类型属次火山热液型层控型。The Suoerkuduke copper deposit has a good prospecting prospect,and it is necessary to carry out the analysis of the genesis of the Suoerkuduke copper deposit.Sulfur isotope samples show that magmatic sulfur is dominated;the characteristics of rare earth elements reflect the characteristics of ore-bearing solution transforming andesitic rocks;the characteristics of hydrogen,oxygen,and carbon isotopes infer that the deposit has hydrothermal superposition metasomatism related to pyroxene diorite characteristics;the temperature measurement results of mineral enclaves show that they are in line with the temperature change law of general skarn deposits.Based on the various information on the genesis of the deposits mentioned above,it is analyzed that the genetic type of the Suoerkuduke copper deposit belongs to the sub-volcanic hydrothermal stratigraphic type.
