Volatile exchange between the Earth interior and the superficial envelopes constitutes an important aspect of global geochemical cycles. Volatile species ranging from major gas components (H2O, CO2, S, halogens) to trace metals are emitted in variable quantities and proportions through magmatic and volcanic activity but also during non-volcanic (e.g. metamorphic) processes. Their emissions occur under various forms (e.g. volcanic gas plumes, particulate matter, soil emanations, bubbling waters, etc.) and thus require widely different methods of investigation. This Session is aimed at making a standpoint in our knowledge of volcanic and non-volcanic Earth degassing in terms of local and global volatile budgets, volatile speciation and degassing processes, relationships with specific tectonic settings, comparison with other natural/anthropogenic sources, and environmental impacts. Contributions from specialists of these various research aspects are welcome.
