High temperature gases circulate through Earth's interior and atmosphere, but little is known about how they react. Recent work shows that exceptionally rapid reactions occur between gases and solids at surfaces. These reactions are instrumental in forming ore deposits and transporting gases and salts to Earth's surface, atmosphere and oceans - affecting climate and biological productivity. This project aims to examine natural samples and investigate gas-solid reactions experimentally to constrain reaction mechanisms. It is expected that the project outcomes will open up a new field of geochemistry with novel experiments, state-of-the-art analysis and the development of innovative models that account for the role of gas-solid reactions in Earth and planetary processes.

高温气体在地球内部和大气中循环，但人们对它们如何反应知之甚少。最近的研究表明，气体和固体在表面上发生异常迅速的反应。这些反应有助于形成矿床，并将气体和盐输送到地球表面、大气层和海洋，影响气候和生物生产力。该项目旨在检查天然样品，并通过实验研究气固反应，以限制反应机制。预计该项目的成果将开辟一个新的地球化学领域，提供新颖的实验、最先进的分析和开发创新模型，说明气固反应在地球和行星过程中的作用。
