阐述了潮水盆地北缘宝家井、阿右旗—唐家沟和陶家井3个地段断块-斜坡带的特征及其成矿条件,认为正向斜坡带有利于蚀源区的含铀含氧水进入盆地盖层的层间,有利于层间氧化带砂岩型铀矿的形成;反向断块-斜坡带和掩埋型断块-斜坡带不利于含铀含氧水进入层间,从而不利于层间氧化带砂岩型铀矿的形成。因此,阿右旗—唐家沟地段是铀成矿有前景的地段。 The characteristics of fault block-slope zone and their metallogenic conditions in Bajiajing, Aouqi-Tangjiagou and Taojiajing in the northern margin of the tidal basin are described. It is concluded that the positive slope zone contains uranium Oxygen enters the interlayer of the caprock and is favorable for the formation of interlayer oxidation zone sandstone-type uranium deposit. Reverse fault-slope zone and buried fault-slope zone are not conducive to the inclusion of oxygenated water containing uranium into the interlayer, Which is not conducive to the formation of interlayer oxidation zone sandstone-type uranium deposits. Therefore, A Youqi - Tangjiagou Lot is uranium metallogenic prospect.
