Stratigraphy, alteration, lithogeochemistry, and genesis of volcanogenic massive sulfide (VMS) mineralization in the Powderhorn Lake area, Newfoundland Appalachians

火山成因块状硫化物（VMS）矿床是加拿大重要的金属来源，为加拿大和全球市场贡献了大量的锌、铅、铜、金和银。该项目将重点了解加拿大纽芬兰中部Powderhorn湖区的寄主岩石和矿化。该地区一直是一个历史悠久的矿区（如布坎斯矿区），Powderhorn湖区是勘探类似矿床类型的重点。这项工作将侧重于利用岩石的场关系、它们的结构和类型，结合岩石化学、矿物化学和同位素测年方法来了解该地区的沉积物是如何形成的，并创建基于场、化学和矿物的工具，这些工具可以用来在纽芬兰中部和全球范围内寻找类似的沉积物。除了提供基础和应用科学（以及潜在的经济效益）之外，该项目还将支持一名硕士学生，该学生将接受现场和实验室方法的培训，并由大学、政府和行业合作伙伴指导。在培训结束时，这些学生将拥有可以直接为加拿大采矿和矿产勘探行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。

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).
