According to the processing results of gravity and magnetic data～at a scale of 1:1000,000) and analysis on relative data in Songliao basin，this paper compa rtmentalizes basement structures, and speculates fault structures of the basin. Meanwhile, on the basis of summing up the achievements of predecessors and in th e light of metallogenic conditions of in-situ leachable sandstone-type uranium d eposits, some favourable uranium metallogenic prospects are predicted. In additi on, this paper also puts forward that attention should be paid to the prospectin g of paleochannel sandstone-type uranium deposits, while we prospect sandstone-t ype uranium deposits in interlayer oxidation zone in Songliao basin.
