摘　　要：小柳沟铜钨矿床有3种成矿构造类型:层间裂隙构造,控制着矽卡岩型矿体,为背斜层间滑动形成的张裂隙;切层裂隙构造,控制着石英脉型矿体,是由深部岩体侵位形成的张裂隙;层间破碎带构造,控制着破碎带型矽卡岩矿体,为背斜层间滑动形成的破碎带.建立的成矿构造模式表明,矿体由背斜构造和岩体侵位构造共同控制.There are three types of metallotectonics in Xiaoliugou Cu-W ore deposit. （ 1 ） Interformational fracture structures. The interformational fracture structures controlling skam-type ore body is extension fracture resulting from anticline. （2） Cut-layer fracture structures. The cut-layer fracture structures controlling quartz vein type ore bod is extension fracture resulting from rock intrude. （3） Interformational faulted zone structures. The interformational faulted zone structures result from anticline controlling faulted-zone-type skam ore body. The metallotectonic model in this rhesear indicates the ore-body is controlled by anticline and rock intruding.
