Volcanogenic massive sulfide (VMS) deposits are critical sources of metals with Canada contributingsignficant zinc, lead, copper, gold, and silver to the Canadian and global market from these deposits. Thisproject will focus on understanding the host rocks and mineralization in the Powderhorn Lake area in central Newfoundland, Canada. This area has been a historic mining area (e.g., Buchans mining district), and the Powderhorn Lake area is the focus of exploration for similar deposit types. This work will focus on utilizing field relationships from rocks, their textures, and types, coupled with rock chemistry, mineralchemistry, and isotopic dating methods to understand how the deposits in this area formed and to create field, chemical, and mineral-based tools that can be utilized to find similar deposits in central Newfoundland and globally. In addition to providing fundamental and applied science (and potential economic benefit), the project will support an MSc student who will be trained in field and laboratory methods, and mentored by university, government, and industry partners. At the end of their training these students will have skills that can directly contribute to the Canadian mining and mineral exploration industry or other similar geoscience professions (e.g., environmental, government, NGO, or university sectors).

火山成因块状硫化物(VMS)矿床是金属的重要来源，加拿大从这些矿床向加拿大和全球市场提供了重要的锌、铅、铜、金和银。该项目将侧重于了解加拿大纽芬兰中部鲍德霍恩湖地区的主岩和矿化作用。该地区一直是历史上的矿区(例如，布昌矿区)，而鲍德霍恩湖地区是类似矿床类型的勘探重点。这项工作将侧重于利用岩石、岩石结构和类型的野外关系，结合岩石化学、矿物化学和同位素测年方法，了解该地区的矿床是如何形成的，并创造可用于在纽芬兰中部和全球寻找类似矿床的野外、化学和矿物工具。除了提供基础科学和应用科学(以及潜在的经济效益)，该项目还将支持一名将接受现场和实验室方法培训的硕士学生，并得到大学、政府和行业合作伙伴的指导。培训结束后，这些学生将掌握可直接为加拿大采矿和矿产勘探业或其他类似的地球科学专业(例如，环境、政府、非政府组织或大学部门)做出贡献的技能。
