Assessing the geochronology,geochemistry and regional tectonic setting of uranium deposits as drivers for exploration

到2030年，全球将有大约500个核反应堆在运行，这将导致全球核能发电量增加66%。随着全球对能源和大宗商品的需求随着世界人口的增长而扩大，加拿大丰富的自然资源将继续享有国际显赫地位。对于铀(U)来说尤其如此，因为在10-20年内，铀将供不应求。为了在竞争日益激烈的采矿和能源勘探市场保持领先地位，加拿大及其行业需要在制定创新和可持续资源开采战略方面处于领先地位。沉积盆地拥有一些世界上最大和最丰富的铀资源，加拿大和世界上有数十个未被勘探的盆地。我们如何区分预期的结构和贫瘠的结构？一种可能的方法是定量比较矿化和贫化的构造构造，以及矿化和贫化流体的来源。铀矿化过程通常与复杂的热液系统有关，这些热液系统涉及反复的断层滑动和沿主要构造的流体流动。因此，了解流体在这些地体内的构造中的运动和铀的来源对矿产勘探具有重要意义。由于寄主岩石、流体成分和可能的温度不同，因此有必要使用不同的同位素方法，从而沉淀出不同类型的矿物。因此，我们建议使用不同的同位素系统来确定断层的年龄和不同矿物的流体成分。这项提议将学术研究人员与行业成员(阿海珐)合作，共同制定更好的铀矿勘探标准。预计的结果是培训4名HQP，并为U和矿业提供一种方法，使他们能够区分贫瘠和矿化的断层和裂缝，从而通过仅针对预期的构造来降低钻井成本和对环境的影响。

Worldwide, there will be ~500 nuclear reactors operating by 2030, which will result in a 66% increase in global nuclear power generation. As global appetite for energy and commodities expands with the world's population, Canada's rich natural resources will continue to enjoy international prominence. This is particularly true for uranium (U) where demand will outstrip supplies in 10-20 years. To remain at the forefront of an ever-competitive mining and energy exploration market, Canada and its industries need to adopt a leadership position in the development of strategies for innovative and sustainable resource extraction. Sedimentary basins are host to some of the largest and richest U resources in the world, and there are tens of underexplored basins in Canada and the world. How can we distinguish between prospective and barren structures? One possible method is to quantitatively compare mineralized and barren tectonic structures, and the source of mineralizing and barren fluids. Uranium mineralizing processes are generally associated with complex hydrothermal systems that involved repeated fault slip and fluid flow along major structures. Consequently, understanding fluid movement through structures within these terrains and the source of U is of great importance for mineral exploration. It is necessary to use different isotopic methods because host rocks, fluid composition and possibly temperature are different, thus, precipitating different types of minerals. Therefore, we propose to use different isotopic systems to determine the age of faults and fluid compositions from different minerals. This proposal brings together academic researchers in partnership with industry members (AREVA) to develop improved exploration criteria for U deposits. The expected outcome is to train 4 HQP, and provide the U and mineral industry with a method that will allow them to distinguish between barren and mineralized faults and fractures, thus reducing drilling costs and impact on the environment by targeting only prospective structures.
