中文摘要	通过对萨热克铜矿床典型勘探线和坑道构造岩相学填图及相体解剖工作,对其沉积相类型、储矿相体结构、成矿作用等进行了研究,认为本区沉积相类型主要为山麓冲积扇相、旱地扇扇中亚相、湿地扇扇中亚相、湖泊沼泽相、滨湖相、浅湖‐半浅湖相、辫状河三角洲前缘亚相等。上侏罗统库孜贡苏组形成以旱地扇残余山间湖泊相(尾闾湖)湿地扇的叠加复合扇扇中亚相(库孜贡苏组上段),叠加复合扇扇中亚相紫红色和灰黑色铁质杂砾岩类为萨热克铜矿床的储矿相体,其微相类型分为水道微相、席状片流微相、叠加复合扇微相、冲刷面微相、筛积微相和泥石流微相。切层断裂‐层间滑动构造形成的碎裂岩化及后期沥青类盆地流体叠加改造部位,矿体具有明显富集作用,显示构造‐岩性‐岩相多重耦合特征。
英文摘要	Through typical prospecting line and gallery construct the petro-graphic mapping and phase body anatomy work, sedimentary facies types and the ore phase structure and mineralization were studied. Results suggest that sedimentary facies are divided into alluvial fan facies, middle-fan subphase of arid fan, middle-fan subphase of humid fan, lake swamp facies, lakeshore facies, shallow lake facies-half shallow lake facies,and braided river delta front subfacies. Kuzigongsu group is mid-fan subfacies of superposition compound fan which is the arid fanresidual mountain lake facies (rump lake) wetland fan. The storage ore phase of Sareke copper deposit is purple and ash black iron conglomerate category in the mid-fan subfacies of superposition compound fan. The sedimentary micro facies types are divided into channel microfacies, sheet flow microfacies, superimposed fan microfacies, large wash surface micro facies, sieve deposition microfacies, and mudslides microfacies. Parts of the cataclastic lithification by the cutting layer fractureinterlaminar slip structure and asphalt class basin-fluid superposition transform are obvious enrichment parts of the ore bodies, showing the structure- lithology- faciesmulti-coupled characteristics.
