We are midway through the General Assembly, and for those of us obsessed with the “unreachable” parts of our planet, Wednesday is the day to be in Vienna!
While the GMPV division is busy monitoring active volcanoes, many of us will be found in the cross-listed sessions where Geochemistry meets Geodynamics and Tectonics. Whether you are a geochemist, a mineralogist, a petrologist, or a volcanologist, today’s program is packed with opportunities to dive deep into the data.
Starting at 08:30, grab your morning coffee or beverage of choice and choose between the volcanic surface or the metamorphic depths: head to Room K1 for the ‘Monitoring active volcanoes‘ session (GMPV11.7). A huge highlight here: at 10:45, our newest GMPV Blog Editor-in-Chief, Agata Poganj, will be presenting her work on how hydrothermal alteration influences permeability (EGU26-341). It’s a great opportunity to see her latest field study and congratulate her on the new role!
But if you prefer the high-pressure world, go to Room G2 for the ‘Fluid-rock interactions‘ session (TS1.5). At 08:30, Anna Rogowitz (solicited) kicks off with a look at HP-metamorphism induced porosity in mafic rocks (EGU26-9041). Immediately after, at 08:45, Andrew Smye will discuss linking reactive fluid flow to the rheology of eclogite-facies oceanic crust (EGU26-15970).
Back from the break, the “unreachable” becomes accessible through two brilliant sessions:
- In Room 0.16: The session ‘Looking into the unreachable: Inclusions as snapshots‘ (GMPV1.1) begins. At 15:00, Alexander Pengg discusses methane and hydrogen in fluid inclusions (EGU26-6278), followed at 15:10 by Guangming Su, who presents a reconstruction of paleo-atmospheric nitrogen pressure using quartz-hosted inclusions (EGU26-5575).
- In Room G2: If you are interested in how grains influence plates, don’t miss ‘Fluid Flow and Rock Interaction Across Scales‘ (TS1.6). Catch Oliver Plümper (solicited) at 14:05 showcasing AI-driven permeability reconstruction (EGU26-3949), and Alessandro Petroccia at 14:15 on tracking dehydration in exhuming shear zones (EGU26-331).
From 16:15, the poster halls become the focal point of the division. In Hall X1, you can dive deeper into the magmatic and volcanic flagship sessions: Monitoring active volcanoes (GMPV11.7), Magmatic textures: petrological insights into igneous processes (GMPV10.2), and Understanding magmatic processes: from magma storage to eruptive behaviour, and implications for volcanic hazard (GMPV10.3).
You should also check out the latest work on Advances in understanding fluid migration systems and their surface manifestations: integrated, multidisciplinary data acquisition and interpretation (GMPV10.5), Volcanic degassing (GMPV10.6), and Volcanoes and their geothermal systems: Properties, risks and resources (GMPV10.7).
If you can tear yourself away from the poster boards in Hall X1 for a quick deviation, head back to Room G2 for the Brittle and ductile deformation of Earth’s lithosphere: Mechanisms governing deformation style session (TS1.1) at 17:40 to catch Alessia Tagliaferri discuss the “memory of crystals” and microstructures in UHP garnets from Dora Maira (EGU26-9776).
Finally, after a day of exploring everything from magmatic storage to mantle inclusions, it’s time to enjoy a night out in Vienna. Join the community for the Pride & Allies Reception (NET13) from 18:00–19:30 at the Rooftop Foyer. It’s a wonderful space to celebrate diversity in geosciences and reflect on the day’s discussions before heading out for some traditional Viennese Schnitzel as we gear up for the final stretch of the conference!
Have a great Wednesday at #EGU26 and check out our blog tomorrow for tips for Thursday!
