Aqueous fluids in the deep earth

该项目旨在提高我们对流体在控制地球深部，浅层岩石和大气之间交换中的作用的理解。该项目预计将利用计算和实验（地球）化学的最新进展，调查用于预测高压和高温下流体中硫、碳和金属行为的热力学模型中的一些关键弱点。结合大规模地球动力学模型，更可靠的预测将提供一个更现实的评估硫的作用，在控制金属禀赋和大气化学通过地质时代。这将为矿物勘探和行星科学提供有用的指导。

This project aims to improve our understanding of the role of fluids in controlling exchanges between the deep Earth, shallow rocks, and atmosphere. The project expects to investigate some of the key weaknesses in the thermodynamic models that are used to predict the behaviour of sulphur, carbon and metals in fluids at high pressure and temperature by using recent advances in computational and experimental (geo)chemistry. Integrated in large-scale geodynamic models, the more reliable predictions will provide a more realistic assessment of the role of sulphur in controlling metal endowment and atmospheric chemistry through geological times. This should provide a useful guide for mineral exploration and planetary science.
