#EGU 2020 Sessions in the Spotlight: Volcanic and Tectonic degassing

We are now just two days from the EGU 2020 abstract deadline! If you are still searching for the ideal session – here’s one for you! GMPV 2.2 – Volcanic and Tectonic desgassing – aims to cover a wide range of topics relating to degassing from magmatic, tectonic and volcanic settings. If you haven’t started writing your abstract yet… good luck!

The convenors say:

Our session is called “GMPV2.2/AS4/NH2/TS13 Volcanic and Tectonic degassing” and it is convened by Nicole Bobrowski (MPI, Mainz), Carlo Cardellini (University of Perugia), Kyriaki Daskalopoulou (GFZ Potsdam), Artur Ionescu (Babes-Bolyai University) and Brendan McCormick Kilbride (University of Manchester).
As magmas rise through the crust beneath volcanoes, they emit gases which may rise through the plumbing system to escape at the surface. By measuring changes in total gas flux and chemical composition, we can better understand a volcano’s state of unrest, by relating these changes in emissions to ongoing magmatic processes such as transport, crystallization or changes in temperature, pressure or other variables. Gases may also rise through the crust far from the site of modern volcanoes, perhaps where deep crustal faults pass close to old and slowly cooling magmatic bodies. In this session, we invite contributions from researchers studying the emission of volatiles from volcanic, magmatic and tectonic systems. We welcome submissions relating to cutting edge measurements techniques, from well-known or little-studied field sites, and research that bridges disciplinary boundaries, for example connecting emissions to geophysical measurements or petrological analyses. We look forward to seeing you in Vienna!
