摘　　要：文章叙述了鄂尔多斯盆地地质概况,重点介绍了槐树湾地区层间氧化带和铀矿化的地质、地球化学特征,探讨了该地区铀矿化的成因机理,指出铀矿化与后生油气还原蚀变作用具有密切的关系。On the basis of brief introduction about regional geology of Ordos basin, this article mainly expounds geological and geochemical characteristics of interlayer oxidation zones （IOZ） and uranium mineralization in Huaishuwan area. The paper discusses the genetic mechanism of this type deposits, and indicates that there is a good relation between uranium mineralization and reduction alteration by oil and gas.

关 键 词：铀矿化特征 油气还原蚀变 成因分析 槐树湾地区
