项目摘要

Hydrothermal fluid flow is fundamental to the formation of almost every class of economic mineral deposit in sedimentary basins. Numerical modeling has proven to be an efficient tool for testing, comparing and contrasting various hypotheses regarding subsurface fluid flow and the resulting ore-forming processes. The proposed research program is aimed at developing and applying geologically and geochemically realistic numerical models for quantifying ore genesis, in particular in unconformity-type uranium mineralization in sedimentary basins. The research will include two components: highly conceptualized fluid flow modeling and geologically realistic fluid flow modeling, with particular reference to the southeastern Athabasca Basins of Canada and the Chanziping uranium district of China. An integrated computational modeling approach with a new software package that fully couples thermal-hydrological-mechanical-chemical processes will be employed to advance our understanding of uranium ore mineralization. The proposed research will result in a theoretical framework to quantify hydrothermal ore-forming fluid flow and its controlling factors under realistic geological, structural and geochemical conditions, and refine a range of effective exploration criteria to target new major uranium deposits in the selected regions and in other similar areas elsewhere in the world. Two Ph.D. students, three M.Sc. students and five undergraduate students will participate in different stages of the proposed research.

沉积盆地中的热液流体活动是几乎所有经济存款形成的基础。数值模拟已被证明是一个有效的工具，测试，比较和对比各种假设地下流体流动和由此产生的成矿过程。拟议的研究计划旨在开发和应用地质和地球化学现实的数值模型，以量化矿石成因，特别是在沉积盆地的不整合型铀矿化。该研究将包括两个部分：高度概念化的流体流动模拟和地质现实的流体流动模拟，特别是参考东南阿萨巴斯卡盆地的加拿大和中国的蝉子坪铀矿区。一个综合的计算模拟方法与一个新的软件包，完全耦合热-水文-机械-化学过程将被用来提高我们对铀矿成矿的理解。拟议的研究将产生一个理论框架，以量化现实地质、构造和地球化学条件下的热液成矿流体流动及其控制因素，并完善一系列有效的勘探标准，以在选定区域和世界其他地方的其他类似地区寻找新的大型铀矿。两个博士学生，三个硕士学生和五个本科生将参加拟议研究的不同阶段。
