Approximately 30% of the world's U reserve is derived from the Athabasca Basin unconformity-type uranium deposits, Canada. These deposits are geologically significant because they are an important energy resource (over 460 million kilograms of U) and they have been used as natural analogues for the geologic disposal of radioactive waste. The unconformity-type uranium deposits from the Athabasca Basin can be subdivided into sandstone-hosted and basement-hosted deposits. Although both subtypes have been studied extensively, understanding the key processes involved in the genesis and subsequent alteration of these deposits has been challenging.

世界上约30%的铀储量来自加拿大阿萨巴斯卡盆地不整合型铀矿床。 这些矿床具有地质意义，因为它们是一种重要的能源（铀超过4.6亿公斤），并被用作放射性废物地质处置的天然类似物。 阿萨巴斯卡盆地不整合型铀矿床可分为砂岩型和基底型两大类。 虽然这两种亚型已被广泛研究，了解这些矿床的成因和随后的蚀变所涉及的关键过程一直具有挑战性。
