摘　　要：松辽盆地西南部地区上白垩统姚家组具备有利于铀成矿的"泥-砂-泥"互层结构,是区内主要的成矿目的层。为分析区内铀成矿环境,探索目的层位发育情况,开展了多年的浅层地震勘探工作。近几年的工作成果及后续地质钻探揭露资料对比分析表明,浅层地震勘探对区内盖层结构的划分、断裂构造的识别、成矿砂体的圈定等方面具有较好的效果,为铀矿勘查提供了丰富的物探资料。The Yaojia Group of Upper Cretaceous is the main metallogenic layer in the southwest of Songliao Basin.The "mud-sand-mud" interbedded structure is beneficial to the uranium mineralization.In order to analyze the metallogenic environment of uranium deposit and explore the development state of target layer in many years,shallow seismic exploration has been carried out in the study area.The comparative analysis of working achievements and the geological survey and drilling work in recent years show that the shallow seismic exploration has a good effect on division of cover-layer structure,identification of fault structure and determination of ore-forming sand body and so on.It has provided for abundant geophysical data in the uranium deposit exploration.
