Volatiles are a key link between the deep Earth and the habitability of our planet's surface. These volatile species are blended at key locations, which can be thought of as interfaces between major geological environments, where distinct geochemical reservoirs meet and interact. These interfaces are the prime locus of movement of volatile species from one Earth reservoir to another, and understanding the fundamental processes which act in these environments is key to unlocking the links between the deep Earth and its surface biosphere. The interfaces we have identified are: (i) oceanic ridges(ii) subduction zones(iii) the mantle transition zone (between the 410 and 660 km discontinuities)(iv) the crustal plutonic realmThe UK has wide expertise in the areas relevant to volatile cycling in the Earth, and we believe that the UK can make a unique contribution to the problem. We propose to focus on the key solid Earth interfaces outlined above, where volatile species are transferred between major geochemical reservoirs, and to formulate fundamental but tractable questions that the UK community can answer with research programme (RP) scale investment. Because work in areas relevant to these problems involves a wide variety of techniques applied over a wide range of pressure and temperature regimes, formulation of these problems is the key challenge of this scoping phase.

挥发物是地球深处与地球表面宜居性之间的关键联系。这些挥发性物质在关键位置混合，这些位置可以被认为是主要地质环境之间的界面，不同的地球化学储层在这里相遇并相互作用。这些界面是挥发性物种从一个地球储存库移动到另一个地球储存库的主要场所，了解在这些环境中起作用的基本过程是解开地球深处与其表面生物圈之间联系的关键。我们已经确定的界面是：(i)洋脊（ii）俯冲带（iii）地幔过渡带（介于410和660公里不连续层之间）（iv）地壳深部构造域。英国在地球挥发性循环相关领域拥有广泛的专业知识，我们相信英国可以在这个问题上做出独特的贡献。我们建议将重点放在上面概述的关键固体地球界面上，其中挥发性物质在主要地球化学储层之间转移，并制定英国社区可以通过研究计划（RP）规模投资回答的基本但易于处理的问题。由于与这些问题相关的领域的工作涉及各种各样的技术，适用于各种压力和温度制度，因此这些问题的制定是该范围界定阶段的关键挑战。
