摘　　要：松辽盆地位于中亚可地浸砂岩型铀矿带的东延部分，其中发育有含油气建造、含煤建造和红色陆相碎屑岩建造。在红色碎屑岩建造中有层间氧化带和“泥-砂-泥”结构发育，并有良好的地下水承压和循环体制，是寻找可地浸砂岩型铀矿的有利地区。Songliao basin is located in the eastern part of in-situ leachable sandstone-type uraniummetallogenetic belt of Middle Asia. where oil-gas-bearing and coal-bearing and red continental elastic rock formations arc developed. Interlayer oxidized zone and argillite-sisandstone-argillite sequence occur in red clastic rock formation with ideal artesian and circulating system of ground water. The basin must be the favourable area for prospecting in-situ leachablesandstone-type uranium deposit.
