摘　　要：研究区位于松辽盆地西南部,继发现QJD层间氧化带型矿床以来,按QJD矿床成矿特征探索相继发现BLS、HLJ、DL等矿化带,找矿前景广阔。通过对松辽盆地西南部晚白垩世以来,前第四系沉积盖层,从区域水文地质条件、含水岩组特征、补给、径流、排泄水动力条件、水文地球化学条件、放射性水化学环境、地下水中同位素特征、古水文地质等特征分析,阐明盖层水文地质特征与铀矿化的关系,近一步说明铀成矿层位水文地质特征及铀矿化形成的有利条件。The study takes the southwest of Songliao Basin was an example.Since the discovery of QJD interlayer oxidation zone deposits,BLS,HLJ,DL and other mineralization zones have been discovered successively according to the mineralization characteristics of QJD deposits,showing a broad prospect for ore prospecting.In southwestern Songliao basin since late cretaceous and before the quaternary sedimentary cover,this paper studied tthe regional hydrogeological conditions,characteristics of water-bearing rock group,recharge,runoff and drainage of water dynamic conditions and hydrogeochemical conditions,radioactive hydrochemical environment,groundwater isotope characteristics,and ancient hydrogeological characteristics.It illustrates the hydrological geology characteristics of caprock relationship with uranium mineralization,and further shows that uranium into a hydrogeological characteristics of ores and forming the favorable conditions of uranium mineralization.
