| Abstract: | The analysis of the sedimentary environment and features, conditions of interlayer oxidization zones' development and setting of uranium mineralization reveals that the lithology, lithofacies and geochemical environment of the 1st sandstone bed of Badaowan Formation. The 1st -3rd sandstone beds of Sangonghe Formation, and the 1st sandstone bed of Xishanyao Formation are favorable for the development of interlayer oxidization zones and uranium mineralization as well as occurrence of anomalies. These beds are the main targets for prospecting in-situ leachable sandstone-type uranium . |
