Dear Colleagues, We invite you to submit an abstract to our AGU25 session, V015. “Fate of Volatiles During Magmatic Processes in Planetary Interiors: Implications on the Origins of Habitability” in the Volcanology, Geochemistry, and Petrology section. Here’s the link to our session: https://urldefense.us/v3/__https://agu.confex.com/agu/agu25/prelim.cgi/Sessi... Please consider submitting an abstract by the soon approaching July 30th deadline. Session Description: The distribution of life enabling elements (e.g., C, S, N, O, H) in terrestrial planets is shaped by how these volatiles were acquired and processed during planetary formation and evolution. Magmatic processes - including core formation, magma ocean degassing and crystallization, volcanic outgassing and subduction - play a central role in controlling the retention, mobility, and distribution of volatiles within planetary interiors. These magmatic processes are intricately linked to dynamic factors like magma ocean convection, crystallization kinetics, and the longevity of partially molten reservoirs. Understanding how this chemical-dynamical interplay influenced volatile element partitioning is key for reconstructing Earth’s path towards habitability. This session invites interdisciplinary contributions exploring these processes through cosmochemical analyses, experimental petrology, thermodynamic modeling, molecular and fluid dynamics, and smoothed-particle hydrodynamics simulations. Submissions leveraging machine learning or AI to advance these investigations are encouraged. We especially encourage participation from early-career researchers and those applying integrative, cross-disciplinary approaches to planetary evolution and habitability.
