This application is for support of collaborative research for a duration of three years between Queen's University and Cameco Corp. to investigate the processes that lead to the formation of uranium deposits associated with peralkaline rocks and the viability of newly developed exploration tools to estimate the potential of alkaline complexes to host uranium mineralization. The test-cases to be studied in detail will be six peralkaline complexes in the USA and Canada, with 50 more complexes to be evaluated for their potential to host uranium mineralization once the exploration criteria have been developed using the test-cases. Samples will be collected from the alkaline complexes and their surrounding rocks to investigate processes such as initial composition, differentiation and contamination that may lead to the formation of igneous-related uranium deposits. Chemical compositions of the rocks, crystal chemistry of the minerals, timing of the mineralization and alteration events will be examined to identify possible vectors to uranium mineralization in alkaline complexes. The ultimate goal is to develop a model for an effective "trapping" mechanism for U associated with igneous rocks, peralkaline in particular, therefore benefitting industry. This research will involve one PhD student, one Post-Doctoral Fellow and two faculty members at Queen's University, along with staff geologists at Cameco Corp. The knowledge generated will be disseminated by written and oral communications with Cameco Corp. and through publications in the scientific literature.

该申请是为了支持女王大学和Cameco公司之间为期三年的合作研究，以调查导致与过碱性岩石相关的铀矿床形成的过程以及新开发的勘探工具的可行性，以估计碱性复合物对铀矿化的潜力。待详细研究的试验案例将是美国和加拿大的六个过碱性复合体，一旦使用试验案例制定了勘探标准，将对另外50个复合体进行评价，以确定它们的铀矿化潜力。将从碱性复合体及其周围岩石中采集样本，以调查可能导致形成与岩浆有关的铀矿的初始成分、分异和污染等过程。将检查岩石的化学成分、矿物的晶体化学、矿化和蚀变事件的时间，以确定碱性复合物中铀矿化的可能载体。最终的目标是建立一个有效的“捕获”机制与火成岩，特别是过碱性的U的模型，因此受益于工业。这项研究将涉及一名博士生，一名博士后研究员和两名教职员工在女王大学，沿着的工作人员在Cameco公司的地质学家所产生的知识将通过书面和口头交流与Cameco公司和通过出版物在科学文献中传播。
