Petrogenesis of magmatic-hydrothermal graphite deposits: A case study of the Albany graphite deposit, northwestern Ontario

赋存于火成岩中的脉型石墨矿床在全球范围内很少见；然而，这些矿床有潜力生产高纯石墨，这是与每年80亿美元的合成石墨市场竞争所需的。超高纯度石墨(&gt；99.95%C)是支持加拿大新兴绿色技术行业所必需的，因为这种类型的石墨是制造锂离子电池、燃料电池、石墨烯应用、球床核反应堆所必需的。加拿大即将开发世界上第一个火成岩赋存的脉状石墨矿床--位于安大略省赫斯特附近的奥尔巴尼矿床。Zenyatta Ventures Ltd是这项拟议研究的行业赞助商，于2010年发现了奥尔巴尼。由于脉状石墨的开采和加工成本比合成石墨(通过昂贵且耗能高的石油焦精炼生产)的生产和环境成本低得多，加拿大的主要好处是为其新兴的绿色技术部门建立了自己的超高纯度石墨供应。尽管潜在的经济效益是巨大的，但由于已知的全球发现很少，因此缺乏关于火成岩赋存脉状矿床的数据，因此对火成岩赋存的地质认识有限。因此，Zenyatta Ventures和莱克黑德大学建立了研究伙伴关系，以研究奥尔巴尼矿藏的来源。这项研究将涉及现场和实验室技术的结合，包括岩心测井、显微研究、全岩地球化学、光谱调查、放射性同位素地球化学、地质年代学和稳定同位素地球化学。除了潜在的长期经济效益外，加拿大还将通过学生培训和研究在短期内受益，这将导致开发出更强大的矿藏模型，加拿大的勘探行业和在海外工作的加拿大公司可以应用这些模型来帮助未来的发现。

Vein-type graphite deposits hosted in igneous rocks are globally rare; however, these deposits have the potential to produce high-purity graphite required to compete with the $8 billion per year synthetic graphite market. Ultra high-purity graphite (>99.95% C) is required to support Canada's emerging green technology sector, as this type of graphite is required for the manufacturing of Li-ion batteries, fuel cells, graphene-based applications, pebble-bed nuclear reactors. Canada is on the verge of potentially developing the world's first igneous-hosted vein graphite deposit, the Albany deposit, near Hearst, ON. Zenyatta Ventures Ltd, who is the industrial sponsor of the proposed research, discovered Albany in 2010. As mining and processing costs for vein graphite would come at much lower production and environmental costs than synthetic graphite (produced by expensive and energy demanding refinement of petroleum coke), the principal benefit to Canada is the establishment of its own supply of ultra-high purity graphite for its emerging green technology sector. Although the potential economic benefits are significant, the geological understanding of igneous-hosted is limited owing to very few known global discoveries and the resulting paucity of data on igneous-hosted vein deposits. Consequently, a research partnership between Zenyatta Ventures and Lakehead University has been established to study the origin of the Albany deposit. This research will involve the integration of field and laboratory techniques, including core logging, microscopic studies, whole-rock geochemistry, spectroscopic investigations, radiogenic isotope geochemistry, geochronology and stable isotope geochemistry. In addition to the potential long-term economic benefits, Canada will benefit in the short-term through student training and research, which will lead to the development of more robust mineral deposit models, which can be applied by exploration industries in Canada and by Canadian companies working abroad to aid in future discoveries.
