Thermal - hydrolic - mechanical - chemical (THMC) modeling of fluid flow and its control on localization of uranium deposits in the northeastern Athabasca basin, Saskatchewan

铀是一种重要的能源，加拿大是世界第二大铀生产国。目前，加拿大所有的铀生产都来自萨斯喀彻温省北方阿萨巴斯卡盆地的高品位铀矿床，即不整合相关铀矿床。其中许多矿床的发现是基于经验模式，即铀矿化发生在横切盆地与基底不整合面的断层附近，含铀氧化性流体在此与还原剂，特别是石墨及其衍生的烃类发生接触并发生反应。然而，随着勘探程度的提高，这一模式面临着越来越多的挑战。需要更好地了解控制成矿作用的因素。

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.
