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）矿床是金属的重要来源，加拿大也有贡献 从这些矿床中向加拿大和全球市场提供重要的锌、铅、铜、金和银。这 该项目将侧重于了解加拿大纽芬兰中部Powderhorn湖地区的主岩和矿化。该地区是一个历史悠久的采矿区（例如，Buchans矿区），而Powderhorn湖地区是勘探类似存款类型的重点。这项工作将侧重于利用从岩石，其纹理和类型，再加上岩石化学，矿物场的关系， 化学和同位素测年方法，以了解该地区的矿床是如何形成的，并创建现场，化学和矿物为基础的工具，可用于在纽芬兰中部和全球寻找类似的矿床。除了提供基础和应用科学（以及潜在的经济效益），该项目还将支持一名理学硕士学生，他们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。在他们的培训结束时，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做出贡献的技能（例如，环境、政府、非政府组织或大学部门）。

Volcanogenic massive sulfide (VMS) deposits are critical sources of metals with Canada contributing signficant zinc, lead, copper, gold, and silver to the Canadian and global market from these deposits. This project 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, mineral chemistry, 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).
