High temperature gases move from Earth's interior to the atmosphere at volcanoes, but little is known about how they react. Recent work shows that exceptionally rapid reactions occur between hot gases and the surfaces of solids. These reactions are instrumental in forming ore deposits. The proposed work aims to apply state-of-the-art chemical analysis of natural samples and investigate gas-solid reactions experimentally to determine how chemical elements, including metals, are distributed in these reactions. The study seeks to create robust geochenmical models for understanding geochemical and ore-forming processes. Improved understanding of ore deposition will enhance the long-term viability of Australia's metals sector.

高温气体从地球内部移动到火山的大气中，但人们对它们的反应知之甚少。最近的研究表明，热气体和固体表面之间会发生异常快速的反应。这些反应有助于形成矿床。拟议的工作旨在应用最先进的自然样品化学分析，并通过实验研究气固反应，以确定包括金属在内的化学元素在这些反应中的分布情况。这项研究试图创建强大的地球化学模型，以了解地球化学和成矿过程。对矿藏认识的提高将增强澳大利亚金属行业的长期生存能力。
