Dear Colleagues, We would like to invite you to consider submitting an abstract to our session: *"06f - Geochemical reactions and interfacial dynamics across scales: Experimental, computational, and AI-driven advances *(*https://conf.goldschmidt.info/goldschmidt/2026/meetingapp.cgi/Session/9012 <https://urldefense.us/v2/url?u=https-3A__conf.goldschmidt.info_goldschmidt_2026_meetingapp.cgi_Session_9012&d=DwMGaQ&c=v4IIwRuZAmwupIjowmMWUmLasxPEgYsgNI-O7C4ViYc&r=tofI8DpgW5YSqX2gxcFvpQ&m=7VJoQZjfkggvp0oLi7LK2_IJGRJNquGOuuHs2OHhOzBXpyGRu1w8p7vS-r8sDv9T&s=wZRj_QSJkgc4BqitjTMdQtc0rP2XAoSULOfHHvVlXBU&e=>* )*”**.* The physics and chemistry of geochemical systems define a rapidly evolving frontier in Earth and environmental sciences. This session brings together experimental, computational, and data-driven perspectives to unravel the mechanisms that govern geochemical reactions, mineral transformations, and interfacial dynamics across multiple spatial and temporal scales. From amorphous precursors to crystalline minerals, and from nanoscale interfacial reactions to field-scale geochemical processes, we aim to advance an integrated understanding of how complex mineral–fluid systems evolve. Topics of interest include, but are not limited to: (1) Mineral-water, organic-mineral interactions, and biomineralization (2) Amorphous and metastable intermediates and nonclassical crystallization (3) Mineral dissolution and weathering (4) Geochemistry of critical elements, connecting nanoscale to macroscopic rates (5) Coupled experimental–computational–AI workflows for predicting mineral reactivity under subsurface environments. By integrating cutting-edge experimental methods, advanced modeling, and AI-enabled approaches, this session aims to illuminate the multiscale dynamics that govern geochemical transformations, enabling predictive understanding of mineral evolution in various systems, including weathering, hydrothermal alteration, carbon storage, and engineered subsurface environments.
