| 摘 要： | 根据水成铀矿成矿理论，本文对柴达木盆地西北部大地构造背景，盆地发展演化史，新构造运动特征，古气候及水文地质条件，铀源及找矿目的层岩性，岩相，地层结构，厚度，埋深，产状等因素综合分析，认为该盆地西北部某些地段具备形成层间氧化带砂岩型铀矿的条件。牛鼻子梁以东是新构造运动相对稳定的地区，其中冷湖地区具备形成大型层间氧化带的条件，是寻找可地浸砂岩型铀矿的有利地区。

| Abstract: | Based on the metallogenic theory of hydrogenic uranium deposits this paper comprehensively analyses the geotectonic setting,the basin development and its evolution,the characteristics of neotectonics,the pal eoclimate,the hydrogeologic conditions,the uranium source,as well as the litholo gy and lithfacies,the stratigraphic texture,the thickness,the occurrence depth o f the target horizon,and suggests that some areas of the northwestern part of th e Chaidam basin possess basic prerequisites for the formation of interlayer oxid ation zone sandstone-type uranium deposits.The area east to Nubizi liang is a n eotectonically relatively stable one.The Lenghu area in the stable area possessi ng conditions for the formation of large-size interlayer oxidation zone is a fa vourable one for locating in-situ leachable sandstone-type uranium deposits. |
