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。
Erlian Basin is a large Mesozoic generation uranium basin. Recently, after continuous inspection of the basin, it was found that it contained a large amount of leachable sandstone-type uranium deposits. This article starts from the two aspects of system research and prospecting results, and gradually finds out the methods and ways to prospecting target layer in Erlian Basin. The prospecting target layer is divided into two levels, the first level is the Saihan group, the second level Erlian group and Erdinger Manha group. Moreover, the type of ore prospecting used in the Erlian Basin is an interlayer oxidation zone (including submersion - interlayer oxidation zone). Then the basis for the existence of leachable sandstone-type uranium deposits is obtained. Then from the theoretical point of view, the prospects for prospecting and ore prospecting in Erlian Basin are listed.
