The study area is located in the southeastern part of the Badanjilin Basin, in the Benbatu region. Multiple airborne radiometric anomalies have been discovered in the area. To further explore the causes of these anomalies and provide references for subsequent uranium exploration work, these airborne radioactive anomalies were classified, summarized, ground verified, and analyzed for their potential for uranium mineralization. The results show that there are two types of anomalies in the area, one is a densely distributed strong anomaly in the central part, which is mainly an airborne radiometric anomaly for exploring hard sandstone-type uranium ores. The other is a weak anomaly distributed in a strip in the southeast, which is mainly an anomaly for exploring in-situ leachable sandstone-type uranium ores and represents a new type of uranium mineralization discovered in the area. By combining regional geological data, the potential for mineralization of the weak anomalies HFU-03 and HFU-04 was analyzed. The research results provide new clues and ideas for the types of uranium exploration in the area.
