二连盆地可地浸砂岩的地球化学特性及铀潜力分析

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。

Geochemistry Characteristics and Uranium Potential Analysis of Leachable Sandstone in Erlian Basin

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.
