Erlian basin is a large cenozoic uranium-productive basin. Recently, after the ongoing visit to the basin, it found that it contained a large number of leachable sandstone-type uranium deposits. From system analysis and prospecting results analysis, this paper finds the ways and means to ore-finding target layers of Erlian basin. Its ore-finding target layer mainly comprises two levels, the first-level group is Saihan group, and the second level is Erlian group and Yierdingman group. And, the ore-finding type used in Erlian basin is interlayer oxidized zone type (including dive-interlayer oxidation zone). Thus it concludes the basis of leachable sandstone-type uranium deposits. From the theoretical point, this paper lists prospects in Erlian basin and its ore prospecting direction.%二连盆地是一个大型中新生代产铀盆地.近期,在不断的对该盆地进行考察之后发现,其蕴藏着大量可地浸砂岩型铀矿.本文从系统研究和找矿成果分析两方面入手,逐步寻找出二连盆地找矿目标层的方法和途径.其找矿目标层主要分两个层级,第一层级是赛汉组,第二层级二连组和伊尔丁曼哈组.并且,在二连盆地运用的找矿类型是层间氧化带型(含潜水-层间氧化带).进而得出了可地浸砂岩型铀矿存在的依据.然后从理论的角度列出二连盆地的找矿前景和找矿方向.
