Abstract: As the development of in-situ leaching technique,sandstone-type uranium deposits have become the key prospecting target for uranium resources in China. In-situ leaching applicable sandstone-type uranium deposits are mainly dominated by interlayered oxidation zone. They are also intimately correlated with erosion source area of high uranium setting,weak neo-structural activities,different paleoclimates in sedimentary and mineralization period,favorable lithofacies and lithology,reducers rich in organic or inorganic matter,favorable dynamic condition of underground water runoff. Based on the macroscopical analysis for the enriched areas of typical sandstone-type uranium deposits and relevant mineralization geological conditions in northwest China,this paper points out that there has been the favorable metallogenic geological conditions and in turn prospecting potential in the Turpan-Hami basin,the southern Yili basin and the surroundings of the Ordos basin. Finally,it presents a forecast for the future prospecting on uranium in northwest China where has the similar geological background like the above basins.
