Most of the World's supply of metals such as copper (Cu), gold (Au), molybdenum (Mo), lead (Pb), zinc (Zn) or uranium (U) comes from hydrothermal ore deposits. The metals were deposited deep below the Earth's surface when hot fluids, carrying minute quantities of the metals, reacted with suitable rocks to form ore minerals. By understanding molecular-level reaction mechanisms at high pressure and temperature, we can predict the nature of the ore minerals formed for a given set of physical and chemical conditions. This multidisciplinary research project is devoted to understanding these chemical and physical processes and how this knowledge can be applied to improve mineral exploration, mining, and ore processing.

世界上大多数金属供应，如铜（Cu），金（Au），钼（Mo），铅（Pb），锌（Zn）或铀（U）来自热液矿床。当携带微量金属的热流体与合适的岩石反应形成矿石时，金属沉积在地球表面以下的深处。通过了解高压和高温下分子水平的反应机制，我们可以预测在给定的物理和化学条件下形成的矿石矿物的性质。 这个多学科研究项目致力于了解这些化学和物理过程，以及如何将这些知识应用于改善矿物勘探，采矿和矿石加工。
