摘　　要：肯德可克矿床是祁漫塔格成矿带最重要的铁多金属矿床之一。前人对肯德可克矿床的地质特征、地球化学特征、成矿年代与物质来源以及成因进行了研究,但对于成矿类型与成矿环境存在不同的认识。肯德可克矿床中的黄铁矿、黄铜矿、磁铁矿、磁黄铁矿、闪锌矿和方铅矿电子探针分析结果表明,黄铁矿与磁黄铁矿均富Co贫Ni,且磁黄铁矿以单斜磁黄铁矿为主;黄铜矿、闪锌矿与方铅矿硫含量较高,且早期磁铁矿较晚期磁铁矿更富集MnO、TiO2。综合各矿物标型特征认为,肯德可克矿床为具矽卡岩型和热液型特征的中低温矿床。Kendekeke deposit is one of the most important iron polymetallic deposits in the Qimantage metallogenic belt and there are a large number of research about geological characteristics,geochemical characteristics,metallogenic age,material source and genesis of the kendekeke deposit,but there are still different understandings of metallogenic type and metallogenic environment.According to the electron probe analysis of pyrite,chalcopyrite,magnetite,pyrrhotite,sphalerite and galena in Kendekeke deposit,the results show that pyrite and pyrrhotite are both rich of Co and poor in Ni,and pyrrhotite is mainly monoclinic pyrrhotite accounts for the majority.S contents of chalcopyrite,sphalerite and galena are higher,while early magnetite is more enriched with MnO and TiO2 than the late.Based on the typomorphic characteristics of each mineral,Kendekeke deposit is considered to be a medium and low temperature deposit with skarn and hydrothermal characteristics.
