The development of industrialized societies requires the use of resources that have to be mined. Among those resources are several important metals (e.g. Cu, Ni, Pd, Pt) that, at present, can only be extracted from deposits formed by cooling of magmas (orthomagmatic deposits) or by interaction of magmas with aqueous fluids (magmatic-hydrothermal deposits). As demands of these metals grow due to the requirements of developed and developing countries and supply diminishes by the progressive exhaustion of known resources, the need to find new deposits for these metals increases. Successful, efficient exploration for these resources and their efficient exploitation relies on our understanding of how such deposits form. Because these resources are limited, every new discovery requires stronger efforts and a better understanding of where mineralization occurs, how these deposits are formed and what controls the spatial distribution of the metals of interests within a particular district. My research is aimed at understanding the geochemical mechanisms that favour the transfer of metals of interest from the Earth's mantle to the crust and the mechanism that control the precipitation of these metals in the anomalous concentrations required for their extraction to be economically feasible. In addition, my research also aims to understand how subsequent thermal events may further remobilize metals and affect the distribution of these metals in their current environments. The goal is to integrate the results of my work with the broader research work on ore deposit genesis to generate models that better predict how and where these deposits can be found in order to optimize exploration and exploitation of these non-renewable resources.

工业化社会的发展需要使用必须开采的资源。在这些资源中，有几种重要的金属（例如Cu，Ni，Pd，PT），目前只能从通过冷却岩浆（正磁沉积物）或通过水性流体（岩浆 - 水热沉积物）形成的沉积物中提取它们（ ）。随着这些金属的需求由于发达国家和发展中国家的要求而增加，并通过逐渐耗尽已知资源而供应减少，因此需要寻找这些金属的新存款的需求增加。这些资源的成功，有效的探索及其有效的剥削取决于我们对这种存款方式的理解。由于这些资源是有限的，因此每个新发现都需要更强大的努力，并更好地了解矿化的发生地点，如何形成这些存款以及哪些控制特定地区利益金属的空间分布。我的研究旨在理解有利于将目标金属从地球层转移到地壳的地壳和控制这些金属在其提取所需的异常浓度以经济上可行所需的异常浓度的机制。此外，我的研究还旨在了解随后的热事件如何进一步重新拟合金属并影响这些金属在当前环境中的分布。目的是将我的工作结果与关于矿床的更广泛的研究工作相结合，以生成模型，以更好地预测如何以及在何处找到这些沉积物，以优化对这些不可再生资源的探索和开发。
