摘　　要：铀矿是核工业的基石,更是国家建设发展的重要战略资源。山西省中条山地区矿产资源具有北铜‒中金‒南铀的时空分布特征,其南段发育数个铀矿(化)点,是铀矿的聚集地;而北段是超大型铜矿产地,其中发育多期次铀矿化作用。扫描电镜及EDS电子图像显示,胡家峪铜矿伴生铀矿物主要为钛铀矿以及淋滤形成的铀黑,赋矿围岩为碳酸盐岩,铀矿化时代为新元古代末期,铀矿物学、年代学特征与南段铀矿(化)点都明显不同。虽然伴生铀矿化形成铀矿床的前景欠佳,但可以考虑增加铜矿开采过程中的商业价值。Uranium ore is the cornerstone of nuclear industry and an important strategic resource for national construction and development.The mineral resources in Zhongtiaoshan region of Shaanxi Province show characteristics of the temporal and spatial distribution of north copper,middle gold and south uranium.There are several uranium mineralized points in the southern section,which is the accumulation of uranium deposits.The northern section is a super large copper orefield,in which multiple stages of accompanied uranium mineralization are developed.The images of SEM and EDS showing that the associated uranium minerals in Hujiayu copper deposit are mainly uranotitanite and uranium black formed by leaching.The ore-bearing wall rock is carbonate rock,and the mineralized age is late Neoproterozoic.The characteristics of uranium mineralogy and chronology are obviously different from those of uranium mineralized points in the southern section.Although the prospect of accompanied uranium mineralization forming uranium deposits is not good,it can be considered to increase the commercial value of copper mining.
