摘　　要：新疆布尔津县科克森套铜多金属矿是典型的岩体接触蚀变型或矽卡岩型铜多金属矿床,位于新疆额尔齐斯成矿带上。基于矿区地质、蚀变矿化、地球化学异常、岩石学及岩石化学等特征,将矿区成矿条件与区域成矿规律进行对比,结合区域成矿模式,评价矿区成矿潜力并进行成矿预测;结合化探数据,参考岩浆岩地球化学特征,探讨矿区及周边的成矿条件,认为区内金既可伴生成矿,又可形成独立的金矿体;该区具有2期成矿作用,且成矿作用强烈,具有良好的找矿前景。Kosentao Cu-polymetallic deposit is a typical intrusive body-contact-alteration type or skarn type ore deposit located in the Eerqisi ore belt.Based on characteristics of geology,mineralization and alteration,petrology,petro-chemistry of the deposit is compared the regional ore-forming condition and that of the deposit,based on the regional ore-forming model potential of the deposit area evaluated and ore predicted.Geochemical survey data and geochemical characteristics of magmatic rock are referred to discuss ore-forming condition of the deposit area and the surroundings.It is considered that Au can be associated with mineralization and independent gold ore body can be formed.There are two mineralization stages in the deposit area and the mineralization is strong.Therefore,the area is potential for further exploratio.
