摘　　要：滇西新生代盆地是我国重要的砂岩型铀矿成矿带之一,蕴藏着丰富的铀资源,现已探明8个中、小型砂岩型铀矿床。笔者回顾了区内砂岩型铀矿找矿历程,分析了找矿现状,介绍了沉积体系与层序地层学在滇西新生代盆地内砂岩型铀矿应用的研究进展;分析了滇西新生代盆地内砂岩型铀矿的找矿前景,提出了扩大老矿区与探索新盆地的找矿思路。Cenozoic basins in west Yunnan as important occurrences of sandstone - type uranium deposits in China are rich in uranium resources with 8 proved medium and small sandstone- type uranium deposits. This paper deals with prospecting experiments and present situation of exploration of the sandstone - type uranium deposits and advances on the application of sedimentary system and sequence stratigraphy to research on the sandstone - type uranium deposits in Cenozoic basins, west Yunnan based on which prospecting potential of the sandstone - type uranium deposits is pointed out.
