摘　　要：根据国内、外现有重要产铀盆地的地质构造背景及其动力学演化,划分出6类产铀盆地,并以每类盆地中的典型代表命名,即楚·萨雷苏-锡尔河式、中央克兹勒库姆式、外乌拉尔-西西伯利亚式、外贝加尔式、波希米亚式和南得克萨斯式。对每类产铀盆地的形成演化模式进行了界定并提出其鉴别标志。最后,分析了各类产铀盆地的区别,提出中国寻找产铀盆地的设想。Based on the study of geologic-tectonic setting and dynamic evolution of important uranium-productive basins both abroad and at home, six types of uranium-productive basins have been distinguished, and each type by typical representative of this type are nominated, namely Chu-Sarysu and Syr-Darya type, Central Kyzylkam type, Zaural and West-Siberia type, Zabaikel type, Bohemia type and South Texas type. The formation-evolution model of each type has been established and recognition criteria have been proposed. Finally, the difference between each type is discussed and some ideas for prospecting uranium-productive basins have been proposed.
