红格尔地区下白垩统沉积体系及砂岩型铀矿成矿前景分析

文章简要地阐述了红格尔地区盆地的地质概况,对找矿目的层下白垩统巴彦花群进行了层序地层划分和沉积体系分析,从铀源、构造、砂体发育规模及地层结构、氧化作用、后生还原作用、水文地质和铀矿化等几个方面对红格尔地区砂岩型铀矿成矿前景进行了分析,提出了砂岩型铀矿成矿远景地段和进一步探索的地段。

Analysis on sedimentary system of Lower Cretaceous and metallogenic prospect of sandstone type uranium deposit in Honggeer area

After a briefly intraduction on the geological setting of basins in Honggeer area,this paper focuses on the sequence stratigraphy division of target prospecting Baiyanhua group of Lower Cretaceous and analysis on its sedimentary system,metallogenic prospect of sandstone type uranium deposit is discussed in the view of uranium source,structure,sandbody scale and layer combination,oxidation and reduction,hydrogeology and uranium mineralization.Fovourable prospecting areas and further exploration deserving sections are proposed at the end.
