为进一步明确柴北缘上干柴沟组铀矿找矿潜力，文章通过对柴北缘仙东地区铀源条件、构造特征、目的层特征、水文地质条件及铀矿化特征进行系统分析，结合区域铀成矿地质背景，讨论了仙东地区上干柴沟组铀成矿条件和成矿阶段。结果表明，仙东地区铀源丰富，发育单斜构造，找矿目的层上干柴沟组发育辫状河三角洲沉积体系，砂体发育层间氧化带和炭屑，地下水“补-径-排”体系完善。铀矿化受层间氧化作用控制明显，矿化强度与S_全、TOC、V、Mo、Re、Se等含量具有明显的正相关关系。铀成矿经历了沉积预富集、层间氧化成矿、构造抬升继续成矿3个阶段。综合分析认为，仙东地区上干柴沟组具有较好的砂岩型铀矿找矿潜力，主要找矿类型为层间氧化带型。
Abstract：To further clarify the prospecting potential of uranium mineralization in Shangganchaigou Formation in the northern margin of Qaidam Basin, this paper systematically analyzed the uranium source conditions, structural characteristics, target layer characteristics, hydrogeological conditions, and uranium mineralization characteristics in Xiandong area of the northern margin of Qaidam Basin. Combined with regional geological conditions, the article discussed the uranium mineralization conditions and stages of Shangganchaigou Formation in Xiandong area. The research suggests that Xiandong region is rich in uranium sources and has developed monocline structures;Shangganchaigou Formation which is the target layer for mineral exploration has developed a braided river delta sedimentary system and recharge-runoff-discharge groundwater system, interlayer oxidation zones and reduced substances such as carbon debris are well developed in the sand bodies. Uranium mineralization is significantly controlled by interlayer oxidation, and the mineralization intensity is positively correlated with Stotal, TOC, V, Mo, Re, Se, and other factors. Uranium mineralization has experienced three stages: sedimentary pre-enrichment, interlayer oxidation mineralization, and continuous mineralization caused by uplift. Comprehensive analysis suggests that Shangganchaigou Formation in Xiandong area has good potential for sandstone type uranium mineralization, with the main type being interlayer oxidation zone type.
