This study involves researchers from Queen's University and experts from Raven Minerals who will focus on identifying the critical factors that control uranium mobility and precipitation in sedimentary basins, and predict where new uranium deposits may reside within specific basin systems in Canada. Sedimentary basins have been selected because they supply most of the world's uranium and are most likely to contain future resources. The research will require four years to complete, involve several HQP (3 Research Associates, 3 PDFs, 3 PhD, 2 MSc, 4 BSc), and will focus on three styles of U mineralization in basins in Canada including: (1) unconformity-related deposits, the highest grade deposits, with research focused on the Athabasca Basin in Canada; (2) terrestrial carbonate (calcrete-type) deposits and their potential to occur in Western Canada Basin; and (3) sandstone-hosted deposits using those in Wyoming and Colorado to assess whether these deposits are likely in Canada. The research will examine when known deposits formed, what environments are required, what chemical reactions were critical in fixing and preserving the deposits, how the deposits have evolved and how areas of uranium mineralization in Canada can be identified through holistic basin analysis and surface sampling. The proposed research will also provide an understanding of the critical factors controlling element migration in the near surface envionment, including the likely source of uranium and pathfinder elements using their isotopes. This will influence exploration given the higher capacity to understand how such deposits can be chemically "imaged" at depth. The benefits to Canadian industry are recognition of both highly prospective and likely barren areas of basins in Canada and new exploration tools and strategies for discovery of undercover uranium deposits, with techniques that are equally applicable to other commodities. The benefits to Queen's researchers and students are the possibility to conduct research in previously understudied areas, the use and development of novel analytical techniques including isotope tracing, and exposure to real-world exploration programs and protocols.

这项研究由来自女王大学的研究人员和 Raven Minerals 的专家参与，他们将重点确定控制沉积盆地中铀流动性和降水的关键因素，并预测新的铀矿床可能位于加拿大特定盆地系统中的位置。之所以选择沉积盆地，是因为它们供应了世界上大部分的铀，并且最有可能蕴藏着未来的资源。该研究需要四年时间才能完成，涉及多名 HQP（3 名研究员、3 名 PDF、3 名博士、2 名硕士、4 名理学士），并将重点关注加拿大盆地的三种类型的铀矿化，包括：（1）与不整合面相关的矿床，品位最高的矿床，研究重点是加拿大的阿萨巴斯卡盆地； (2) 陆地碳酸盐（钙质凝结石型）矿床及其在加拿大西部盆地出现的潜力； (3) 砂岩矿床，使用怀俄明州和科罗拉多州的砂岩矿床来评估这些矿床是否可能位于加拿大。该研究将研究已知矿床形成的时间、需要什么环境、哪些化学反应对于固定和保存矿床至关重要、矿床如何演化以及如何通过整体盆地分析和表面采样来识别加拿大的铀矿化区域。拟议的研究还将了解控制近地表环境中元素迁移的关键因素，包括铀的可能来源和使用其同位素的探路者元素。鉴于了解如何在深度对此类矿床进行化学“成像”的更高能力，这将影响勘探。对加拿大工业的好处是认识到加拿大盆地的高前景和可能贫瘠的地区，以及发现地下铀矿床的新勘探工具和战略，其技术同样适用于其他商品。女王大学的研究人员和学生的好处是可以在以前未充分研究的领域进行研究，使用和开发包括同位素追踪在内的新颖分析技术，以及接触现实世界的勘探计划和协议。
