| 摘 要： | 松辽盆地是上叠于海西褶皱带基底之上的中新生代陆相沉积盆地。舍伯吐地区位于松辽盆地西南部，区内上第三系松散堆积层赋存有3层稳定的砂体。砂体中均发育有不同规模的区域性层间氧化带。经钻探揭露，榆树屯地段Ⅱ层砂体的层间氧化-还原过渡带比较典型，并有铀和钼的次生富集，这一发现为松辽盆地找矿工作的突破展现了良好的前景。

| Abstract: | Songliao basin is a Meso Cenozoic continental basin superimposed on the Hercynian fold belt.Shebotu area is located in the southwest of Songliao basin where three sandstone beds exist in Neogene loose sediments.Regional interlayer oxidation zones of various scale are developed in sand bodies.Drilling has revealed that typical interlayer oxidation zone is developed in sand body No.II in Yushutun,and the redox zone is associated with the secondary concentration of uranium and molybdenum.This discovery presents bright prospects for the final progress in uranium prospecting in Songliao basin. |
