摘      要：The Qianjiadian uranium deposit is located in the Kailu Depression of Songliao *** is a large-scale in-situ leachable uranium deposit of sandstone type and provides a typical case of the uranium deposits in the Songliao *** we analyze the impact of oil and gas on reduction alteration,and factors including low grade *** Qianjiadian uranium deposit is characterized as a typical rolltype deposit with interlayers in oxidized *** occurrence of reductive low-permeability sandstone in uranium reservoirs controls the morphology of the uranium-rich *** propose a metallogenic model involving multi-stage superposition characterized by“primary sediment enrichment-interlayer oxidation-superimposed transformation.Our model would be helpful for formulating guidelines in the exploration for sandstone-type uranium deposits in the Songliao Basin.
