Goldschmidt 2026 Arc Volcanoes Inside Out

[Annika Dechert]

Dear all, 

We invite you to submit an abstract to Goldschmidt 2026 for our session titled Arc Volcanoes Inside Out: Linking Magmatic Processes to Eruption Hazards. We are excited to showcase interdisciplinary perspectives on subduction-zone magmatic systems and welcome contributions from scientists at all career stages. 

The abstract deadline is February 26, 2026. Please find the session description below. 

We look forward to seeing you all in Montreal, Canada, July 12–17, 2026! 

Best, 

Annika Dechert

Title: Arc Volcanoes Inside Out: Linking Magmatic Processes to Eruption Hazards

Session: 04e

Theme 04: Magmatism and Volcanism: Impacts and Consequences

Session Description: Volcanic eruptions profoundly impact communities worldwide, with arc volcanoes posing some of the greatest hazards. By focusing on subduction-zone magmatic systems, this session aims to advance our understanding of magma genesis, chemical evolution, storage conditions, eruption primers, triggers and associated timescales — ultimately probing the architecture and dynamics of these systems. We welcome contributions that investigate eruptive products across scales, from microanalytical and geochemical observations (e.g., melt inclusions, crystal zoning, isotopes, volatiles), to field studies and experimental approaches. Interdisciplinary perspectives are strongly encouraged, including work that integrates geochemistry with geophysics, physical volcanology, and numerical or analytical modeling, as well as studies that link petrological observations to volcanic unrest. By connecting micro-scale geochemical and textural signatures to broader volcanic processes and behavior, this session seeks to bridge observations of volcanic products with large-scale hazard implications. In doing so, we highlight the value of combining diverse methods to better understand volcanic unrest and improve hazard assessment.
