摘　　要：文章将我国中新生代陆相盆地中发育的古层间氧化带砂岩型铀矿床分为地层超覆埋藏亚型、构造抬升破坏亚型、构造褶断保存亚型等3种亚型,文中主要讨论了这3种亚型古层间氧化带砂岩型铀矿床的成矿特点、成矿模式及找矿前景。作者认为,除近代层间氧化带砂岩型铀矿床以外,古层间氧化带砂岩型铀矿床在我国中新生代陆相盆地也有很大的找矿潜力。因此,需要从成矿理论上认真总结和不断充实,以推动我国砂岩型铀矿找矿工作不断向前发展。In this paper, the paleo-interlayer-oxidation type sandstone-hosted uranium deposits occurred in the Meso-Cenozoic continental basins in China are divided into 3 subtype, they are stratum over lapping buried subtype, structure-uplifting destroy subtype and faulted-folding conserved subtype. The metallogenic characteristics, metallogenic model and exploration prospect for these 3 subtypes uranium deposits are discussed. It is proposed that the paleo-interlayer-oxidation type sandstone-hosted uranium deposits, besides the recent interlayer oxidation type sandstone-hosted uranium deposits, are of great prospecting potential in the Meso-Cenozoic continental basins in China. Therefore, the metallogenic theory of these types uranium deposits should be conscientiously summarized and replenished continuously so as to propel forward the exploration of the sandstone-hosted uranium deposits in China.
