| Abstract: | 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. |
