摘　　要：本文在阐述了松辽盆地的区域地质构造特征、盆地北部区域铀源条件及含铀层位的基础上 ,论述了大庆油田北部铀矿化分布特点及铀矿化特征 ,并从沉积成岩作用、古水文地质、氧化 还原地球化学分带控矿的角度对该区铀矿化的成因进行了探讨。On the basis of regional geologic tectonic features of the Songliao basin,and the regional uranium source and uranium hosting horizons, distribution features and characteristics of uranium mineralizations in northern Daqing oil field are introduced in this paper,and the genesis of uranium mineralization in the region is discussed from aspects of ore controlling factors,such as sedimentary diagenesis,paleohydrogeology,geochemical redox zoning etc.
