鄂尔多斯盆地是我国北方重要的产铀盆地之一，但其南部地区的铀矿地质工作相对比较薄弱。笔者从铀源、构造、沉积建造、沉积相、层间氧化作用及物化遥等方面总结了鄂尔多斯盆地南部地区的铀矿预测要素特征，在 GIS平台上采用 MRAS软件和特征分析法，圈定并优选出Ⅰ、Ⅱ级远景区各1处；认为店头瑶曲地段、彬县旬邑地段是盆地南部砂岩型铀矿找矿的有利地区。

Ordos basin is an important U producing basin in northern China.Geological work for sandG stone hosted uranium deposits is relatively weak in the southern area of Ordos basin.In this paper,eleG ments for uranium prognosis in southern Ordos have been summarized in aspects of uranium sources,geG ological structures,sedimentary formations and facies,interlayer oxidation,as well as geophysical,geoG chemical and remote sensing characteristics.With the MRAS software on platform of GIS,characteristic analysis method is applied to select the perspectives and one level Ⅰ and one level Ⅱ perspective areas were predicted,and Diantou Yaoqu section and Binxian Xunyi section are finally determined as favoraG ble for uranium prospecting.
