Uranium is an important source of energy, and Canada is the second largest uranium producer in the world. Currently all the uranium production in Canada is from high-grade uranium deposits known as unconformity-related uranium deposits in the Athabasca Basin in northern Saskatchewan. Many of these deposits were discovered based on an empirical model that uranium mineralization took place near faults crosscutting the unconformity between the basin and the basement, where uranium-bearing oxidizing fluids met and reacted with reducing agents, especially graphite and hydrocarbons derived from it. However, with increasing degrees of exploration, this model is facing more and more challenges, and a better understanding of the factors controlling mineralization is needed.

铀是一种重要的能源，加拿大是世界上第二大铀生产国。目前，加拿大所有的铀产量都来自萨斯喀彻温省北部阿萨巴斯卡盆地的高品位铀矿床，即与不整合有关的铀矿床。这些矿床中有许多是根据一个经验模型发现的，即铀矿化发生在盆地与基底之间不整合面横切的断层附近，在那里，含铀氧化流体与还原剂相遇并发生反应，特别是与石墨及其衍生的碳氢化合物。然而，随着勘探程度的提高，该模型面临越来越多的挑战，需要更好地了解控矿因素。
