在澳大利亚北部地区和加拿大萨斯喀彻温省阿萨巴斯卡盆地发现的与古地表有关的铀矿床,在当代和今后世界能源供应方面有着重要意义。关于这些矿床成因有各种解释,诸如变质作用、热液活动和同生过程等。我们认为这些矿床是与大陆风化作用有关的后生富集结果。以后的再造作用包括热液活 Uranium deposits associated with palaeontology, found in the northern regions of Australia and the Athabasca Basin, Saskatchewan, Canada, are of major importance in contemporary and future world energy supply. There are various explanations of the origin of these deposits, such as metamorphism, hydrothermal activity and syncytial processes. We believe these deposits are the result of epigenetic enrichment associated with the weathering of the continent. Future rework includes hydrothermal activity
