| Abstract: | This paper comprehensively analyses the geotectonic setting and favourable conditions,such as structure of the basin, sedimentary factes and paleogeography, geomorphology andclimate, hydrodynamics and hydrogeochemistry, the development of interlayered oxidationetc,necessary for the formation of sandstone uranium deposit of interlayered oxidation type,and further proposes the following prospecting criteria, namely: abundant uranium source,arid climate,stable big basin, flat-lying sandstone bed, big alluvial fan,little change in sedimentary facies,intercalation of sandstone and mudstone beds, shallow burying of sandstonebed, well-aquiferous sandstone bed,high permeability of sandstone bed,development of interlayered oxidation,and high content of reductant in sandstone. In addition, the 6 in 1 hydrogenic genetic model is proposed. |
