摘　　要：本文根据野外调查及室内系列编图成果 ,分析了巴音宝力格隆起带中新生代盆地砂岩型铀矿成矿地质条件 ,认为下白垩统巴彦花组是中新生代盆地的找矿目的层位 ,并存在古河道与潜水层间氧化带两种砂岩型铀矿类型。巴彦毛都、准巴彦塔拉。On the basis of field reconnaissance and results of compiling a series of prognostic maps,the ore formation conditions of sandstone type uranium deposit in Meso Cenozoic basins at the Bayinbaolige uplifted zone are analysed in this paper.It is suggested that the Bayanhua Group,Lower Cretaceous is the prospecting target horizon,and two types of sandstone hosted uranium deposits,(the paleochannel,and the interlayer oxidation zone)many occur in the region,and Bayinmaodu,Zhunbayintala,Wuliyasitai basins are perspective for the formation of sandstone type uranium deposits.
