Dear All, We invite you to submit an abstract to Session 06e - Advances in computational thermodynamic modelling and machine learning tools for geological and planetary processes, for the 2026 Goldschmidt Conference in Montreal, Canada (July 12-17th). We are pleased to announce that Dr Aaron Wolf will be the Keynote speaker for this session, who will talk about the new functions of MELTS ENKI! Session Description: This session explores recent developments in methods and tools for advancing thermodynamic modelling of geochemical processes. These advances include both improvements to computational approaches, based on Gibbs Energy minimisations, as well as new developments using machine learning (ML)-based techniques. Computational thermodynamic software tools (e.g., MELTS, THERMOCALC) rely on existing databases and thermodynamically-derived solution models. Recent improvements (e.g., ENKI, GEMS, ThermoHub, MAGEMin, Reaktoro, Cantera, etc.) have been developed to broaden the range of geological and planetary settings in which existing thermodynamic models can be applied, and to assist in developing new thermodynamic models. Concurrently, ML techniques are increasingly applied to accelerate the prediction of mineral stability and chemistry, evolution of liquid compositions of major oxides, aqueous speciation, mineral thermobarometers, and reaction kinetics, and to fill gaps in thermodynamic properties and model parameters. This session invites contributions that demonstrate how novel computational approaches (e.g., Bayesian methods, speciation, or expanded compositional systems), including both traditional and machine-learning approaches, can advance the creation and application of thermodynamic models. Application of such models might include magmatic systems, crustal evolution, shallow and deep magmatic brines and other fluids, and non-terrestrial planet compositions. Our session 06e is part of Theme 06: Analytical and computational frontiers Abstract submission details and session information can be found here: https://conf.goldschmidt.info/goldschmidt/2026/meetingapp.cgi/Session/1190 The abstract submission deadline is February 26th, 2026. We welcome abstracts from people of all career stages and research backgrounds. Please feel free to share this invitation with colleagues, collaborators, and students who might be interested in submitting an abstract to our session. We are looking forward to hosting a widely attended, diverse and productive session! Sincerely, Romana Boiger Ri Cao Simon Matthews George Dan Miron
