摘　　要：依据小柳沟钨钼矿区勘查及生产中赋矿地质体所表现出的特征以及近年研究的新成果,在总结前人研究成果基础上,对小柳沟钨钼矿成矿规律进一步细化、补充、明确。通过地层及矿化的演化研究对比,认为小柳沟钨矿成矿地质体矽卡岩化有多期,前期矽卡岩化对成矿元素进一步富集起到了促进作用,后期的矽卡岩化才是主成矿期;认为钨钼成矿有时空交叉,两者成矿热液存在同步运移和富集的可能,钨钼的主矿化期极有可能均在闪长花岗岩活动时期。According to the characteristics of ore-bearing geological bodies in the exploration and production of Xiaoliugou tungsten and molybdenum deposit and the new research results in recent years,the metallogenic law of Xiaoliugou tungsten and molybdenum deposit is further refined,supplemented and clarified on the basis of summarizing the previous research results.Based on the study of the evolution of strata and mineralization,it is concluded that there are multiple stages of skarn mineralization in the metallogenic body of Xiaoliugou tungsten deposit.The early stage of skarn mineralization promotes the further enrichment of ore-forming elements,and the late stage of skarn mineralization is the main ore-forming stage.It is believed that there is a time-space intersection of tungsten and molybdenum mineralization,and there is the possibility of synchronous migration and enrichment of ore-forming hydrothermal fluids.
