摘　　要：松辽盆地为中国北方大型内陆盆地之一，总面积达２０万平方公里。它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。The Songliao Basin is one of large intracontinental basins in northern China.The total area is 260 000 2Km,It is located in the extending eastward part of the central Asian leachable sandstone type U area.Among which,there are the developed oil gas bearing formation,coal bearing formation and red continental clastic rock formation.There are interlayer oxidized zone and the developed“mud sand mud”texture in the red clastic rock formation,as well as suitable confined and cyclic system,being a favourable area to prospect for leachable sandstone type U.
