Volcanogenic massive sulfide (VMS) deposits contain some of Canada's most significant sources of copper, lead, zinc, gold and silver, and are thought to have formed within submarine volcanoes similar to those presently forming on the modern seafloor. This proposed research will examine deposits hosted within ancient seafloor volcanic rocks and will investigate mineral and chemical changes associated with the interaction of hot metal-rich fluids with seawater, sedimentary and volcanic rocks. This research will focus on the origin, formation and setting of these submarine sedimentary and volcanic rocks. By improving our understanding of VMS deposits and their associated rocks, I will be able to provide predictive methods for the discovery, exploration, and exploitation of these important metal resources.

火山块状硫化物 (VMS) 矿床含有加拿大一些最重要的铜、铅、锌、金和银来源，并且被认为是在海底火山内形成的，类似于目前在现代海底形成的火山。这项拟议的研究将检查古代海底火山岩中的沉积物，并将研究与富含热金属的流体与海水、沉积岩和火山岩相互作用相关的矿物和化学变化。 这项研究将重点研究这些海底沉积岩和火山岩的起源、形成和环境。 通过提高我们对 VMS 矿床及其伴生岩石的了解，我将能够为这些重要金属资源的发现、勘探和开采提供预测方法。
