The recently-discovered world-class Black Thor - Black Label chromite deposit in the McFaulds Lake ("Ring of Fire") area of northern Ontario will make Canada a major produce of this strategic metal. However, exploration for additional resources requires that we understand why these particular rocks contain so much chromite when so many other rocks in Ontario and elsewhere with apparently similar compositions contain so little chromite. This project will use state-of-the-art geological, mineralogical, textural, geochemical, and isotopic analytical methods to evaluate how the magma that formed the rocks was generated, how so much chromite accumulated, and how to recognize this process in other areas. It will train 1 PhD student and 3 MSc students, contribute to our knowledge of these deposits in particular and chromite deposits in general, and aid in mineral exploration in the McFaulds Lake area and elsewhere in the world.

最近在安大略北方的麦克福兹湖（“火环”）地区发现的世界级黑托尔-黑标签铬铁矿存款将使加拿大成为这种战略金属的主要生产国。然而，勘探额外的资源要求我们理解为什么这些特定的岩石含有如此多的铬铁矿，而安大略和其他地方的许多其他岩石具有明显相似的成分，含有如此少的铬铁矿。该项目将使用最先进的地质学，矿物学，结构，地球化学和同位素分析方法来评估形成岩石的岩浆是如何产生的，如何积累如此多的铬铁矿，以及如何在其他地区识别这一过程。它将培训1名博士生和3名硕士生，为我们特别是这些矿床和一般铬铁矿矿床的知识做出贡献，并帮助麦克福兹湖地区和世界其他地方的矿产勘探。
