摘　　要：红旗岭硫化铜镍矿床是一组矿床,产于吉林省中南部,典型矿床有红旗岭1号矿床。辉发河大断裂是穿壳岩石圈深断裂,是镁铁超镁铁质岩浆上升的通道。硫化铜镍矿床产于燕山期镁铁超镁铁质岩体中。对含矿岩体的岩石化学和地球化学研究表明,形成含矿岩体的岩浆为钙碱性玄武岩岩浆,并后期混染了壳源物质。矿床主要形成于岩浆熔离作用,伴有接触交代及热液成矿的叠加,矿床成因类型为岩浆深部熔离贯入型。Located in the central southern Jilin Province, the Hongqiling CU-Ni mine comprises of a group of deposits and typical ones among them include the No.1 of the Hongqiling. Researchers considered the Huifahe Fracture Zone is deep, crust-cut, lithospheric fracture which provided a channel for the upward migration of the mafc and ultramafc magmas. The sulfde Cu-Ni deposits in the area hosted in the Yanshanian mafc-ultramafc rocks. Research on the petrochemistry and geochemistry shows that, the magma related to ore-bearing intrusion belongs to calc-alkalic basatic magma but contaminated by crust materials. The ore deposits were formed by magma liquation, accompanied by contact replacement and reworked by hydrothermal fluids. The genesis of the deposits belongs to a composite type of deep-liquation and injection.
