摘    要:通过对新疆乌恰地区萨热克铜矿床的构造岩相学实测剖面研究,认为萨热克巴依复式向斜构造有利于盆地流体大规模聚集成矿,且萨热克铜矿床受构造和盆地流体作用影响形成南、北两个矿带。北矿带储矿构造样式为褶皱群落+顺层断层+层间连通性复式断裂-裂隙带,后期具有强沥青化流体侵入特征;南矿带储矿构造样式为传播褶皱+侵入构造+穿层断裂-裂隙带。典型钻孔及坑道的构造岩相学相体解剖研究结果表明:上侏罗统库孜贡苏组二段旱地扇扇中亚相杂砾岩为矿质的初始富集岩性,矿体在膝折构造及沿断裂构造侵位的辉绿岩脉部位增厚;层间和切层断裂-裂隙发育最密集构造应力区为富烃类还原性成矿流体提供运移通道及储矿空间;总体显示萨热克铜矿具有构造与成矿流体叠加耦合作用特征。

关 键 词:铜矿床  构造系统  构造岩相学  储矿构造样式  叠加耦合  盆地流体  辉绿岩  新疆

Abstract:Through the study on the tectonic petrographic profile of Sareke Cu deposit in Wuqia area of Xinjiang, it is considered that the complex synclinal structure in Sarekebayi is conducive to the large-scale accumulation and mineralization of the basin fluid, and it is affected by structure and basin fluid action, and the Sareke Cu deposit forms two ore belts in north and south. The ore-contained tectonic styles of the north ore belt are composed of fold community, bedding fault and interlayer connectivity complex fault-fracture zone, and it is characterized by strong asphaltization fluid intrusion in the later stage; the ore-contained tectonic styles of the south ore belt are composed of propagation fold, intrusion structure, trans-layer fault-fracture zone. Combined with the study on the lithological phase anatomy of typical boreholes and tunnels, the results show that the heterogeneous conglomerate of the central dryland fan subfacies in the second member of Upper Jurassic Kuzigongsu Formation is the initial enrichment lithology of mineral, and the ore body becomes thick in the location of knee-fold structure and diabase vein along the fault structure; the most dense tectonic stress zone in the trans-layer fault-fracture zone provides migration channels and storage space for hydrocarbon-rich reducing ore-forming fluids, and it is generally shown that Sareke Cu deposit has a characteristic of the superimposed coupling of structure and mineral fluid.
Keywords:Cu deposit  tectonic system  structural petrography  ore-contained tectonic style  superimposed coupling  basin fluid  diabase  Xinjiang
