中文摘要:尽管世界铀矿床数量众多，超大型铀矿床却以极少的数量贡献了巨大的铀资源储量，在世界铀矿生产和供应中具有“关键少数”的重要作用。超大型铀矿床具有成矿类型偏在性，不整合面型、黑色页岩型和可地浸开采的砂岩型是当前世界铀矿勘查开发的最佳类型。超大型铀矿床在成矿时代、成矿区域、成矿背景等方面也有十分明显的选择性，元古宙和中新生代是铀矿形成的高峰时期。澳大利亚、加拿大、哈萨克斯坦、俄罗斯、纳米比亚、南非是超大型铀矿床的主要分布区和铀矿勘查开发的主要目标区，克拉通则是铀矿勘查开发的首要战略选区。
Abstract:Despite the fact that there are numerous uranium deposits in the world, the superlarge uranium deposits contribute a majority percentage of the world's total uranium resources with only a small number deposits, playing a crucial role in the production and supply of uranium. The superlarge uranium deposits have the preferentiality of mineralization type, with discontinuous surface-type, black shale-type, and sandstone-type being the best types for uranium exploration and development worldwide. The superlarge uranium deposits also show a clear preference of metallogenic era, region, and background, with the Proterozoic and Meso-cenozoic being peak periods for uranium mineralization, and Australia, Canada, Kazakhstan, Russia, Namibia, and South Africa being the main distribution areas and the main target areas for uranium exploration and development. The cratons are the top strategic choice for uranium exploration and development.
