摘　　要：笔者通过野外岩心观察、室内显微观察、钻孔和沉积剖面对比,以及沉积微相划分,综合分析了蒙其古尔地区赋铀层的砂体厚度和砂地比特征,绘制了沉积微相展布图。从岩石学和沉积相两个方面,讨论了区内赋铀层沉积特征与砂岩型铀矿的关系。Based on core observation, microscopic observation, comparison of borehole to sedimentary section and sedimentary microfacies analysis, the thickness, thickness ratio of sandbeds to uranous strata were comprehensively analysed and the micro sedimentary faces was mapped in Mengqiguer area. The relationship between sedimentary characteristics and uranium mineralization was discussed in lithology and sedimentary faces.
