鄂尔多斯盆地南缘城阳—武沟地区航放异常铀找矿前景分析

An analysis of the prospect in the search for uranium deposits in the aerial radioactive anomaly area of Chengyang-Wugou region on the southern margin of Ordos basin

研究区位于鄂尔多斯盆地南缘西部,处于天环凹陷西翼,分布有Ⅰ-160砂岩型铀矿点。笔者依据对前人资料的收集、整理,结合研究区分布的航空放射性异常查证结果,对区内铀成矿条件进行分析,探讨了铀找矿前景。分析认为城阳—武沟地区存在有利的找矿目的层,具备较好的砂岩型铀成矿条件,航空放射性异常区是重点找矿地段,圈定了1片铀找矿有利区。

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.
