1-1-1-1-1-1-1-1-1-1-1-1-1-1 From: Severine MOUNE <moune@xxxxxxx> Dear Colleagues, Geoff Kilgour (GNS) and I (Severine Moune, IPGP/OVSG) are guest editors for a Special Issue of Geosciences "Magma degassing from magma at depth to the surface" that aims to gather high-quality and original research articles, reviews and technical notes on degassing from magma at depth to the surface. Here you can find the outlines of this specie issue: Volcanoes are commonly observed to emit larger amounts of gas than can be dissolved in the volume of erupted magma, especially in subduction zones. Combined with an understanding of the underlying mechanisms, quantification of this so-called excess degassing can provide valuable insights into eruptive processes. The dynamics of eruptive processes are linked to both the gas composition in magmas and the physics of degassing, but no single approach is sufficient for describing the full range of these dynamics. Thus, it is crucial to integrate studies on the behaviour and transfer of volatile components from their starting conditions in the deep magmatic system (e.g., pre-eruptive content, volatile solubility) through ascent in the volcanic conduit and release into the atmosphere (e.g. gas composition and flux, ash-gas-aerosol interactions). Combining these data with state-of-the-art geophysical methods and numerical modelling, will improve our understanding of the dynamics of magma degassing. Multi-disciplinary approaches with measurements of dissolved, exsolved and emitted magmatic volatiles are essential to increase our knowledge of eruptive processes. Therefore, we would like to invite contributions from all fields of geochemistry, geophysics, and petrology that use field, analytical, numerical, analogue and experimental approaches on the dynamics of magma degassing. More information could be found here: https://www.mdpi.com/journal/geosciences/special_issues/Magma_depth_surface If you wish to participate, please send in an attempted title and abstract. The special issue should be finalized by the end of the year. Please, then, circulate and propagate this special issue among your colleagues and students Looking forward to hearing from you. Take care of yourself and your family! 1-1-1-1-1-1-1-1-1-1-1-1-1-1 ============================================================== Volcano Listserv is a collaborative venture among Arizona State University (ASU), Portland State University (PSU), the Global Volcanism Program (GVP) of the Smithsonian Institution's National Museum of Natural History, and the International Association for Volcanology and Chemistry of the Earth's Interior (IAVCEI).
