摘　　要：本文通过对松辽盆地地质条件下铀源条件、矿化异常与后期改造的数据分析与研究,得出以下结论:第一、松辽盆地边缘地区可作为今后地浸砂岩型铀矿找矿和研究工作重点,其中双辽地区和缘庆安地区为重点找矿区。第二、松辽盆地白垩系中泉头组和登娄库组为重点矿化异常层位,白垩系各组段地层中盆地边缘的河流相地层为找寻铀矿的重点对象。Based on analysis and research of the uranium source conditions, mineralization abnormal and late reformatory data of Songliao Basin geological conditions, reached the following conclusions：First, the margin area of the Songliao Basin can be used as the prospecting and research focus of the leachable sandstone uranium deposit in the future, the Shuangliao and Qing＆#39;an region as the focus prospect area. Second, Cretaceous Quantou Formation and Denglouku Formation in Songliao Basin are mineralization anomalies horizon, fluvial facies stratum on the edge of basin in Cretaceous section strata are key target for uranium.
