The data generated in this study will be used to enhance the integrated geological model for the geology and mineralization of the Highland Valley and MAX porphyry systems in British Columbia. We will utilise high precision geochemistry and radiogenic isotopes to investigate the role of tectonic triggers on the formation of porphyry and epithermal deposits. The model that will be developed will be compared to existing data sets for other porphyry deposits around the globe. In addition we will develop the next generation of fertility assessment tools for porphyry systems by assessing the chemistry of key magmatic fertility indicator minerals (e.g., zircon and hornblende) through LA-ICPMS analyses of trace element compositions. Finally we will assess the mineral chemistry of alteration minerals associated with porphyry systems in order to assess their

本研究产生的数据将用于增强不列颠哥伦比亚省高地谷和MAX斑岩系统地质和矿化的综合地质模型。我们将利用高精度地球化学和放射性同位素来研究构造触发因素对斑岩和浅成低温热液矿床形成的作用。将开发的模型与地球仪其他斑岩矿床的现有数据集进行比较。此外，我们将通过评估关键岩浆肥力指标矿物的化学性质（例如，锆石和角闪石）进行LA-ICPMS微量元素组成分析。最后，我们将评估与斑岩系统相关的蚀变矿物的矿物化学，以评估其
