Dear Colleagues, We enthusiastically invite you to submit an abstract to our AGU 25 session, entitled: V007: Crystal Records of Magmatic Processes Crystals in igneous rocks represent detailed archives of magmatic system evolution, preserving information on composition, temperature, pressure, oxygen fugacity, volatile content and key processes such as fractional crystallization, magma mixing, and assimilation. These records span magmatic environments from the upper mantle to the crust, offering insights into the conditions and timescales of magma generation, storage, and transport. This session brings together researchers studying magmatic crystals in mafic to felsic rocks across diverse tectonic settings to explore questions related to magma sources, evolution, storage dynamics, and process timescales. We welcome contributions that employ a range of established and emerging techniques, including (but not limited to) textural analysis, microbeam methods, experimental approaches, X-ray micro-computed tomography, thermodynamic and numerical modeling, machine learning, big data analysis, and diffusion chronometry. The deadline for all submissions is Wednesday, 30 July 2025 at 23:59 EDT/03:59 UTC. All the best and hoping to seeing you in New Orleans, The conveners: Oliver Higgins, University of St. Andrews Weiran Li, University of Hong Kong Marc-Antoine Longpré, Queens College, City University of New York Kendra J.
