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.
