Mineral chemistry as a vector to mineralisation in porphyry systems**

该项目将研究不列颠哥伦比亚省温哥华岛Pemberton Hills岩盖和伴生斑岩矿化的高级泥质蚀变的矿物和全岩石化学。该研究产生的数据将用于开发斑岩系统和伴生岩盖周围蚀变足迹的新模型。通过利用过去12年来在斑岩矿床周围开发的矿物化学工具，我们将使用蚀变矿物的微量元素地球化学来开发评估这些系统的前景和肥沃度的方法，以及通过与岩盖相关的强烈蚀变的能力。我们将研究明矾石、石英、黄铁矿、绿柱石和白色云母的微量元素化学，以测试我们是否可以扩大已知晕的大小作为矿产勘探工具，并研究使用短波红外和便携式x射线荧光作为现场工具来获得相同的结果。对矿化的近端和远端矢量的识别将为斑岩和浅成热液矿床提供更有效的勘探策略，这对于下一代的发现很可能来自埋藏矿床至关重要。此外，该项目将大大有助于我们了解产生这些复杂矿化系统的过程。该项目还将培养年轻的研究人员，使他们在学术界、政府部门或工业界在地球科学领域取得成功。

This project will investigate the mineral and whole rock chemistry of the advanced argillic alteration within the Pemberton Hills lithocap and associated porphyry mineralization on Vancouver Island, B.C. The data generated in this study will be used to develop new models for the alteration footprints around porphyry systems and the associated lithocaps. By utilizing mineral chemistry tools that have been developed over the past 12 years around porphyry deposits, we will use the trace element geochemistry of alteration minerals to develop methods to assess the prospectivity and fertility of these systems, as well as the ability to see through the**intense alteration associated with lithocaps. We will investigate the trace element chemistry of alunite, quartz, pyrite, epidote, and white mica in order to test whether or not we can extend the size of the known halo as a tool for mineral exploration and investigate the use of Short Wave Infra Red and Portable X-Ray Flourescence as field based tools to achieve the same results. The recognition of the proximal and distal vectors towards mineralization will lead to more efficient exploration strategies for porphyry and epithermal deposits, which is critical given that the next generation of discoveries are likely going to come from buried deposits. In addition the project will contribute significantly to our understanding of the processes that generate these complex mineralized systems. This project will also train young researchers for a successful career in the geosciences whether in academia, government or industry.
