中文摘要:
      以柴达木盆地北缘团鱼山地区为研究对象,在对以往煤田钻孔资料二次开发和放射性异常查证后,对铀源基础、岩性-岩相、构造条件、地形地貌特征、水文条件及氧化还原环境等铀矿成矿背景及条件进行研究,得出团鱼山地区具备铀成矿有利条件,中侏罗统石门沟组下段砂岩层段为最有利的目的层,成矿类型为层间氧化带型,建议向南追索层间氧化带,寻找有利靶区。
英文摘要:
      The Tuanyushan area has been taken as the research subject in this paper, the previous coalfield drilling data has been systematically analyzed, and the radioactive anomalies have been verified in this paper. And then, the metallogenic conditions of sandstone-type uranium deposits have been discussed, such as uranium source condition, lithology and lithofacies, tectonic conditions, terrain and landform characteristic, hydrogeologic conditions and oxidation-reduction environment. The results show that the Tuanyushan area has favorable conditions for uranium mineralization. According to the metallogenic characteristics of this studying area, it is indicated that the sandstone in the lower member of Middle Jurassic Shimengou Formation is a favorable mineralization horizon, with metallogenic type of interlayer oxidation zone type. Therefore, it is suggested that the interlayer oxidation zone should be pursued southward as a favorable target area.
