摘　　要：萨热克铜矿床赋存于萨热克巴依上叠盆地,成矿类型有3类:产于北带上侏罗统砾岩中的沉积—改造型铜矿,矿物组合主要为辉铜矿、黄铜矿、黄铁矿,元素组合为Cu-Ag-Ba;产于南带上侏罗统砾岩中的沉积—热液叠加改造型铜矿,矿物组合主要为黄铜矿、辉铜矿、方铅矿、闪锌矿、黄铁矿,元素组合为Cu-Pb(Zn)-Ag-Ba-(As、Sb);产于上白垩统的砂岩铜矿,以孔雀石为主,元素组合为Cu-Ag等。通过化探普查所获异常规模大、强度高、各元素浓集中心套合较好。经地质评价、工程验证,已探获铜资源量达大型规模,可综合利用的矿产尚有银、铅锌、钼等。Abstract：The Sareke copper deposit occurs in the Sarekebayi superposed basin.There are three types of metallogenic types：a,sediment-originated reformed type copper deposit in the north mineralization belt in the Jurassic conglomerate rock,principal minerals are chalcocite,chalcopyrite and pyrite.The element association is Cu-Ag-Ba.b,depositional hydrothermal superimposed transformation type copper deposit in the southern belt in the Jurassic conglomerate rock unit,the principal minerals are chalcopyrite,chalcocite,galena,sphalerite and pyrite,the element combination is Cu-Pb （Zn）-Ag-Ba-（AsSb） ; c,sandstone type copper deposit formed in Upper Cretaceous age,the mineral is dominated by malchite,and the element association is Cu-Ag.The geochemical anomalies outlined by the geochemical survey are characteristized with the large scale size,high anomalous strength and consistent enrichment for each element anomaly.The Sareke copper deposit resources reaches large scale by the geological evaluation and test enginnering work,and the comprehensive utilization of metal resources are silver,lead and zinc and molybdenum etc.
