This project will focus on the Volcanic Massive Sulphide (VMS) and gold mineralization of the Lundmark-Akow portion of the North Caribou Greenstone Belt (NCGB) in the northern Superior Province. Two MSc students and up to three BSc students will use fundamental geological mapping and logging, combined with traditional and state-of-the-art analytical techniques, to characterize the mineralized systems in this poorly understood portion of the NCGB. One student will characterize the >11 km long alteration pathway/zone of coarse-grained staurolite-garnet+/-biotite-sericite schists that show geochemical characteristics typical of VMS related systems. The second will focus on characterizing the two styles of gold mineralization in the Lundmark-Akow Lake area to assess what, if any, relationship they have with the VMS mineralization. The proposed research will combine basic field and petrographic studies with well established (whole rock geochemistry, stable and radiogenic isotopes) and novel (e.g., mineral chemistry from LA-ICP-MS, EMPA, in situ isotope studies) geochemical techniques to fully characterise the paragenesis and alteration of the mineralization and the rocks that host them.The data generated in this study will be used by Romios Gold Resources Inc., to enhance their exploration efforts, and hopefully lead to increased mineral production. This project will contribute to our understanding of the NCGB and characterize the mineralization so as to develop models that can be used to target high-grade zones of mineralization. We will develop tools that can be applied by Canadian companies to aid in generating future discoveries. The discovery and development of new mineral resources is critical to the well-being of Canada's economy and this project will lead to greater efficiencies in that process.

该项目将侧重于北方上级省北驯鹿绿岩带（NCGB）Lundmark-Akow部分的火山块状硫化物（VMS）和金矿化。两名理学硕士学生和多达三名理学学士学生将使用基础地质测绘和测井，结合传统和最先进的分析技术，来描述NCGB这一鲜为人知的部分的矿化系统。一名学生将描述>11 km长的粗粒十字石-石榴石+/-黑云母-绢云母片岩蚀变通道/带的特征，其显示VMS相关系统的典型地球化学特征。第二个将侧重于描述Lundmark-Akow湖地区两种类型的金矿化，以评估它们与VMS矿化的关系。拟议的研究将结合联合收割机的基本领域和岩相学研究与完善的（全岩地球化学，稳定和放射性同位素）和新的（例如，矿物化学从LA-ICP-MS，EMPA，原位同位素研究）地球化学技术，以充分说明共生和蚀变的矿化和岩石的主机他们。在这项研究中产生的数据将使用Romios黄金资源公司，以加强他们的勘探工作，并有望导致增加矿产产量。该项目将有助于我们对NCGB的理解，并描述矿化特征，以便开发可用于靶向高品位矿化带的模型。我们将开发可供加拿大公司应用的工具，以帮助产生未来的发现。新矿产资源的发现和开发对加拿大经济的福祉至关重要，该项目将提高这一进程的效率。
