摘　　要：连山关铀矿床是在元古代时代背景下形成的典型中型混合热液改造型矿床。为进一步提升开发潜力,结合矿山多年来探采实践,对该矿床成因特征进行系统分析,重点对铀的成矿特征和成矿关系进行了探讨,并初步总结铀矿成矿模式。研究认为,连山关地区具备较好的铀成矿地质条件和物理化学条件,区内北西西向韧性剪切带与北东向断裂构造的交汇部位具有较大的找矿潜力,暗色岩脉对铀的沉淀富集起到重要作用。在成矿理论指导下提出了矿床未来深部找矿方向,对延长矿山服务年限具有深远的意义。The Lianshanguan uranium deposit is a typical medium-sized mixed hydrothermal reformed deposit formed in the Proterozoic era.In order to further enhance the development potential,combined with the exploration and mining practice of the mine over the years,the genetic characteristics of the deposit were systematically analyzed,with emphasis on the metallogenic characteristics and metallogenic relationship of uranium,and a preliminary summary of the metallogenic model of uranium deposits.The study shows that the Lianshanguan area has good uranium metallogenic geological and physical and chemical conditions,and the intersection of the NW-trending ductile shear zone and the NE-trending fault structure in the area has great prospecting potential.Dark dikes play an important role in the precipitation and enrichment of uranium.Under the guidance of metallogenic theory,the future deep prospecting direction of the deposit is proposed,which has far-reaching significance for extending the service life of the mine.
