Redox evolution of basaltic magmas

该项目旨在帮助我们了解地球地幔的氧化还原状态（化学物质的氧化和还原）及其在空间和时间上的变化。地幔的氧化还原状态控制着铁等元素的价态和挥发物（如氢、碳和硫）的形态，这些挥发物从火山中脱气并最终构成大气。该项目旨在量化各种类型的玄武岩浆所经历的氧化还原状态的变化。该项目的成果可以帮助我们模拟金属在岩浆中的迁移，预测矿床，并评估火山脱气挥发物的性质和相对贡献。

The project aims to contribute to our understanding of the redox state (the oxidation and reduction of chemicals) of the Earth’s mantle and how it changes in space and time. The redox state of the Earth’s mantle controls the valency of elements such as iron and the speciation of volatiles (eg hydrogen, carbon and sulphur) that degas from volcanoes and ultimately make up the atmosphere. This project aims to quantify the changes in redox state experienced by various types of basaltic magmas. The outcomes of the project could help us to model the transport of metals in magmas and predict ore deposits, and assess the nature and relative contributions of volatiles that degas from volcanoes.
