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.

这项研究涉及皇后大学的研究人员以及乌鸦矿物的专家，他们将着重于确定控制铀流动性和沉积盆地降水量的关键因素，并预测加拿大特定盆地系统中新的铀沉积物可能位于何处。之所以选择沉积盆地，是因为它们提供了世界上大部分铀，并且最有可能包含未来的资源。这项研究将需要四年才能完成，涉及几个HQP（3个研究助理，3个PDF，3 phd，2 MSC，4 BSC），并将重点介绍加拿大盆地的三种U矿化样式，包括：（1）不兼容的矿床，最高等级的沉积物，最高等级的沉积物，其研究重点是加拿大的Athabasca Basin； （2）陆地碳酸盐（咖啡酸盐型）沉积物及其在加拿大西部盆地发生的潜力； （3）使用怀俄明州和科罗拉多州的砂岩托管沉积物来评估这些沉积物是否可能在加拿大。该研究将检查何时形成已知的沉积物，需要哪些环境，哪些化学反应在固定和保存沉积物，如何发展沉积物以及如何通过整体盆地分析和表面采样来鉴定加拿大铀矿化区域。拟议的研究还将提供对控制近表面设想中控制元素迁移的关键因素的理解，包括使用其同位素的铀和探路者元素的来源。鉴于更高的能力了解如何在深度上“化学成像”，这将影响勘探。加拿大工业的好处是认可加拿大盆地的高度潜在和可能的贫瘠地区，以及发现卧底铀矿床的新勘探工具以及策略，其技术同样适用于其他商品。女王的研究人员和学生的好处是可以在先前研究的领域进行研究，包括同位素追踪在内的新型分析技术的使用和开发，以及接触现实世界中的探索计划和协议。
