摘　　要：潮水盆地是全国49个铀成矿远景区带之一,高精度航放航磁资料已经覆盖全盆,为充分挖掘找矿有利信息,文章在对盆地航放航磁数据进行整理并编图的基础上,归纳总结了研究区航放、航磁特征,通过求取初始铀、活性铀、铀迁移富集系数等参量对铀迁移规律进行研究,结合盆地内铀源条件、构造条件和水文地质条件等进行铀成矿条件的分析,认为潮水盆地具备有利铀成矿条件,并在平易一带、大红山一带和唐家沟一带圈定3片找矿有利区,为开展下一步工作提供了线索。Chaoshui basin is one of the forty-nine uranium metallogenic prospective zones in China,Which are covered by high precision airborne radioactivity and aeromagnetic data.In order to fully exploit the favorable information for uranium prospecting,this paper summarized airborne radioactivity and aeromagnetic characteristics by tiding and mapping the data of the basin.The patterns of uranium migration were studied by calculating the parameters of initial uranium,active uranium and uranium migration-enrichment coefficient.The uranium mineralization conditions were analyzed in the source conditions,tectonic conditions and hydrogeological conditions.It was believed that Chaoshui basin was favorable for uranium mineralization,and three favorable prospecting areas have been delineated in the areas of Pingyuan,Dahongshan and Tangjiagou,which provided clues for the further work.
