Mineral-fluid reactions in metamorphism and carbon sequestration

该项目将评估矿物流体反应在调节地球深部流体流动和吸收大气中的温室气体二氧化碳方面的作用。地壳内部深部的流体流动可能控制地壳在造山和岩浆作用期间的行为。流体流动对一些金属和高科技工业矿藏的形成也是必不可少的，并影响变形期间的岩石行为(如地震事件)。流体流动的关键控制是矿物反应和岩石变形形成和破坏渗透性通道。同样，矿物反应也有助于从大气中长期封存二氧化碳。一个有希望的应用领域是利用工业废物，如矿山尾矿，捕获和结合数千年来的二氧化碳，从而有助于缓解气候变化问题。

This project will assess the role of mineral fluid reactions in modulating fluid flow in Earth’s deep crust and in absorbing the greenhouse gas carbon dioxide from the atmosphere. Fluid flow at depth within Earth's crust may control how the crust behaves during mountain building and magmatism. Fluid flow is also essential for the formation of some metallic and high-tech industrial mineral ore deposits, and influences rock behaviour during deformation (e.g., earthquake events). A critical control on fluid flow is the formation and destruction of permeable pathways by mineral reactions and rock deformation. Likewise, mineral reactions can contribute towards the long term sequestration of carbon dioxide from the atmosphere. One promising area of application is in using industrial waste, such as mine tailings, to capture and bind carbon dioxide for millennia, thus contributing to the mitigation of the climate change problem.
