摘　　要：本文论述了公婆泉盆地下白垩统新民堡群的层序地层特点———层序分布和时代、界面特征和内部构成、沉积相,以及层间氧化带和铀矿化特点。认为该盆地在公婆泉地段具有一定的找铀矿远景,但北骆驼泉地段铀成矿条件不佳,那林疏怀地段不具备铀成矿远景。Characteristics of sequence stratigraphy, the distribution and the geologic time of sequence, boundary features and internal composition, the sedimentary facies, as well as the characteristics of interlayer oxidation zone and U-mineralization are expounded in this paper. It is suggested that the Gongpoquan area is of certain prospect for U-prospecting, and uranium metallogenic conditions are not favorable in the Beiluotuoquan area, and the Nalinsuhuai area has no prospect either.
