摘　　要：从基础地质条件出发,全面分析了酒东盆地铀矿成矿条件,认为该盆地具有丰富的成矿物质来源和良好的构造,沉积条件和平缓南倾单斜构造、河流和三角洲沉积体系,具有"泥-砂-泥"结构,水文地质条件较好,补-径-排体系较完善,地下水化学分带性明显,后生蚀变强烈,具备了层间承压水氧化带砂岩型铀矿成矿地质条件,找矿潜力大。Jiudong basin uranium metallogenic conditions are comprehensively analyzed from aspects of basic geology in this the research work. It is concluded that the basin has abundant uranium source and monoclinic structure gently tilted southward, and river and delta sedimentary environment, with “mud-sand-mud” structure, relatively good hydrogeological conditions, more perfect system of recharge-runoff-drainage, obvious chemical zoning of groundwater, epigenetic alteration. with geological conditions for sandstone type of uranium mineralization in interlayer confined water oxidation zone. Such geological conditions indicates big prospecting potential.
