Volcanic halogens across the earth system: from magma to atmosphere
Hôtel Dupanloup

Presentation
Halogens play an important role in volcanic systems and their environmental impacts, alongside the main volcanic volatiles (water-vapor, carbon dioxide, and sulfur). Volcanic halogens (fluorine, chlorine, bromine, and iodine) influence the evolution of magmatic systems over time, the transport and fate of metals, and degassing processes leading to passive and eruptive emissions. On entering the atmosphere, halogens in volcanic emission-plumes can undergo chemical reactions that impact atmospheric chemistry, ozone and climate, and exert further influences on the environment and ecosystems by their deposition. Volcanic halogens interact with co-emitted ash particles and can influence the nitrogen, sulfur, and mercury cycles.
Tracing volcanic halogens behavior and fate alongside other volatiles in the volcano-atmosphere-environment system is a complex challenge. Recent advances and newly developed research tools across laboratory experiments, field/observation and model studies are enabling to better quantify and characterize volcanic halogens processes within each of the various earth compartments and to bridge knowledge gaps from the mantle to the atmosphere. When brought together, these advances can collectively inform about the environmental impacts of volcanic halogens, their influence on largescale cycles and their evolution in the earth system (and for other planets), and the potential use of volcanic halogens datasets to contribute to observatory efforts to monitor and predict eruption hazards.
We seek to gather together the earth-science and chemistry-climate communities - from France and Internationally - for a multidisciplinary workshop to share our research on volcanic halogens.
This workshop is sponsored by the LEFE CHAT, LE STUDIUM, the H’allo Volcano International Consortium and the ANR Consortium VOLC-HAL-CLIM.

Location
Hôtel Dupanloup : 1, rue Dupanloup - 45000 ORLEANS - FR
The conference venue is unique. Located right next to the Orléans’ cathedral, the episcopal palace of Orléans, built between 1635 and 1641, locally known as the Hôtel Dupanloup, is a classical French building which served until 1905 of residence to the bishops of Orléans. Since 2014, the renewed palace hosts the International University Center for Research and Le Studium Loire Valley Institute for Advanced Studies.
Participants will be welcomed in this exceptional surrounding, blending Middle Age and Renaissance cultures with modern design and will have the opportunity to discover French cuisine and wines.
