We would like to invite you to submit an abstract to the session GMPV2.3:
Insight into the deep geochemical behaviour of trace volatiles: from the
crust to the core
which will be held at the EGU general assembly in Vienna, from the 23th

Description of the session
Long-term geochemical behaviour of volatile components such as carbon,
sulfur, halogens and noble gases in the Earth is of key importance for
understanding numerous geological phenomena, including magmatic
processes, interactions between rocks and fluids in subduction zones,
and interactions between the deep Earth and the surface.
The very low concentrations of some volatile species (e.g. noble gases,
halogens) in many host phases make their study challenging. To better
constrain their geochemical behaviour from the upper crust to the
Earth’s core, we need additional quantitative data on volatile
partitioning and diffusion in minerals, melts, fluids and gases. The
role of the crystal-chemistry of minerals, as well as that of melt and
fluid composition in controlling the incorporation of volatiles needs to
be emphasized alongside extensive parameters, such as temperature,
pressure, redox or pH conditions.
The present session aims at bringing together analytical, experimental
and computational studies that dive into the complex behaviour of
volatile species in the deep Earth, from the rock- to the atom-scales.
We encourage but are not limited to contributions addressing the
distribution of volatiles between minerals, melts and fluids, the
behaviour of volatiles in the lower mantle and the core, and the role
played by volatiles in the geodynamical cycles of the deep interiors.
