The Tidal Basin is a Mesozoic-Cenozoic stretching fault basin in central Alxa platform uplift on the northern side of the Hexi Corridor.In this basis,there are four uranium deposits belonging to sandstone type,mudstone type and coal rock type,thirteen uranium ore spots and dozens of uranium mineralized spots.Through an analysis of the verification results of airborne radioactive anomalies distributed in Pingyi depression of the Tidal Basin in combination with ore-forming geological setting,metallogenic characteristics,uranium source and ore-prospecting target bed of the basin,the authors investigated the vista in search for uranium deposits on the southern margin of Pingyi depression in the Tidal Basin.The analysis shows that Cretaceous strata in Pingyi area have favorable ore-prospecting target bed which seems to be the breakthrough point of ore-prospecting,and the airborne radioactive anomaly area is the key ore-prospecting segment deserving further investigation.
