Petrogenesis of the Kiyuk Lake Gold Deposit, Nunavut

这项研究将是女王同位素研究机构(QFIR)和繁荣金矿公司为评估Kiyuk湖金矿的起源和演化而进行的首次合作。这是一个不同寻常的金矿床，因为它赋存于一个沉积盆地中，位于努纳武特一个未被勘探的地区。目前，加拿大的大部分黄金都是从加拿大盾最古老的部分生产的。如果能在较年轻的盆地(如Kiyuk Lake)中发现经济数量的黄金，那么在盾牌中将确定一个新的黄金沉积时间，并将揭示一个潜在的黄金新宿主。需要解决的问题包括蚀变矿物的类型及其相对于金的形成顺序、与金有关的蚀变组合的年龄和化学、相对于贫瘠地区产生金的流体的来源和特征，以及如何利用这些流体来探测该地区的金矿化。这项研究将涉及一名硕士学生和一名博士后研究员(0.2PDF)和两名研究助理(他们5%的时间是RAS)来产生数据和新的勘探技术，监督研究和指导HQP的PI，以及将提供钻探岩心样本和补充数据的繁荣金矿公司的工作人员。产生的数据和知识将是原创的，重点放在一个赋存于地质中的金矿床上，该金矿床几乎没有对其矿产潜力进行评估。这一知识将为该行业提供寻找额外储量的工具，如果它们存在的话，也将使加拿大和努纳武特受益，因为它们提高了对努纳武特潜在的新类型和新金矿成矿区域的认识。此外，它还将评估在露头暴露非常有限的地区使用地球化学进行有效评估和勘探的情况。

This research will be a first collaborative effort between the Queen's Facility for Isotope Research (QFIR) and Prosperity Goldfields to evaluate the origin and evolution of the Kiyuk Lake gold deposit. This is an unusual gold deposit because it is hosted in a sedimentary basin and is in an underexplored area of Nunavut. Currently much of Canada's gold is produced from the oldest parts of the Canadian Shield. If economic amounts of gold could be found in younger basins such as at Kiyuk Lake, a new timing for gold deposition will have been identified in the Shield and a potential new host for gold will be revealed. Problems to be addressed include the types of alteration minerals and their order of formation relative the gold, the age and chemistry of the alteration assemblages associated with the gold, the origin and character of the fluids that produced the gold relative to barren areas, and how these can be used to detect gold mineralization in the area. This research will involve an MSc student and a Post-Doctoral Fellow (0.2PDF) and 2 Research Associates (5% of their time as RAs) to produce data and new exploration techniques, the PI who will oversee the research and mentor the HQP, and the staff at Prosperity Goldfields who will provide drill core samples and supplementary data. The data and knowledge generated will be original and focussed on a gold deposit hosted in geology that has seen little assessment for its mineral potential. This knowledge will benefit the industry by providing tools to find additional reserves if they are present, as well as both Canada and Nunavut by increasing awareness of potentially new types and areas of gold mineralization in Nunavut. In addition, it will evaluate the use of geochemistry for effective valuation and exploration in an area with very limited outcrop exposure.
