This two-day online workshop includes hands-on tutorials, lectures, and discussions about current numerical thermodynamic modeling methods, the databases required, and the experimental approaches used for studying metal transport associated with fluid-rock interaction in the crust. The goal of this workshop is to link thermodynamic modeling and experimental approaches with examples from natural systems, and bring together a broad community interested in the interpretation of crustal metasomatism and ore-forming processes.

The workshop is intended for graduate students, researchers, and professionals whom want to learn how to apply the GEMS code package ( to geochemical modeling, as well as learn about how to use current experimental methods regarding fluid-rock equilibria to interpret the evolution of natural ore-forming systems at elevated P-T conditions. The GEMS code package is based on Gibbs energy minimization, and provides a user-friendly framework for predicting mass transfer in complex non-ideal systems such as those associated with fluid-rock interaction and oreforming processes.

The workshop will cover: 1) fundamentals of the GEM-Selektor code package and the MINES thermodynamic database for simulating fluid-rock systems; 2) the ThermoEcos ( framework to manage and evaluate large thermodynamic and experimental datasets; 3) an overview of experimental methods to study the stability and mobility of metasomatically induced and altered REE mineral phases in crustal rocks (e.g. monazite, xenotime, apatite, allanite, and titanite); 4) field case studies of metasomatism and associated mineral deposits. Register for this workshop through the conference registration page - please make sure to register for both parts in order to participate on both days! Price: €35 per part / €70 for both parts. For questions please contact Alexander Gysi.
