The classification of uraniferous basin type is one of the most important foundation in uranium deposit prospecting, so far systematic comparative study of continental basins in northern China has not been carried out. Aided by prospecting practice of sandstone- type uranium deposits in northern China, unique sandsotone uranium metallogenic theory of fluctuating mineralization process, “Red & Black” syndepositional structures in ore- controlling, uplifts structures of basin margin in ore- controlling etc have been brought out, all the theories supervise prospecting and enriched through the practice, as a result prospecting breakthrough of sandstone- type uranium deposits was achived. Based on 30 million meters core information, on the basement of uraniferous formations time and uranium enrichment mechanisms, considering tectonic setting of basins and geotectonic evolution background, type classification of Mesozoic- Cenozoic uraniferous basins is proposed, including composite sedimentary basin, superimposed sedimentary basin and simple sedimentary basin. Composite sedimentary basin is a kind of uraniferous basin in which uraniferous formations are Mesozoic strata and sandstone- type uranium deposits lie in several formations, for example the uraniferous formations in Ordos Basin include Middle Jurassic uraniferous formation and Cretaceous formation. Superimposed sedimentary basin is a kind of uraniferous basin, uraniferous formations of which include Mesozoic structural layer and Cenozoic structural layer, for example, the Junggar Basin and Qaidam Basin. Simple sedimentary basin is a kind of uraniferous basin which only include Cenozoic uraniferous formations, for example, Longchuanjiang Basin. According to the space distribution between Tectonic magmatic belts and uraniferous basins, uraniferous basins are divided into the basin between magmatic belts and the basin in magmatic belts. Type classification of Mesozoic- Cenozoic uraniferous basins in northern China does not only have great significance in metallogenic environment of sandstone- type uranium deposits, metallogenic regularity and metallogenic model,but also in practical implications of prospecting.
