Abstract

The study area is located in the west of the southern margin of Ordos basin, on the western wing of Tianhuan depression, where Ⅰ-160 sandstone-type uranium ore spot exists. Based on the collection and collation of previous data and combined with the investigation results of airborne radioactive anomalies distributed in the study area, the author analyzed uranium mineralization conditions in this region and discussed the prospect of uranium exploration. It is concluded that there are favorable ore-hunting zones in the Chengyang-Wugou area, which has better conditions of sandstone-type uranium mineralization, with the aviation radioactive anomaly being the key prospecting area. The author delineated a favorable area for uranium prospecting. The results obtained by the author seem to have directive significance in the acceleration of the exploration of uranium and mineral resources in this region.

Key words： southern margin of Ordos Basin abnormal aerial radioactivity prospect of uranium search
