MINES Thermodynamic Database — Workshops

Past Workshops:

Goldschmidt Conference Workshop, Lyon, France, July 8-9, 2023
Ore-forming processes and metasomatism: combining experimental and modeling methods to interpret field observations

Organizers: Alexander Gysi (NMT), Nicole Hurtig (NMT), Pan Ruiguang (NMT), Daniel Harlov (GFZ Potsdam), Dan Miron (PSI, Switzerland), Dmitrii Kulik (PSI, Switzerland)

The goal of this workshop is to bring together a broad community interested in the interpretation of crustal metasomatism and ore-forming processes. This two-day workshop includes hands-on tutorials, lectures, and discussions about current thermodynamic modeling methods, the databases required, and the experimental approaches used to study metasomatism and element transport associated with hydrothermal fluid-rock interaction in the crust. Short discussion sessions will be included in order for the audience to find connections between the content of the workshop and their own particular interests in crustal fluid-rock interaction, including examples from both natural systems and experiments.

The workshop is intended for graduate students, researchers, and professionals who want to learn how to apply the GEMS code package (http://gems.web.psi.ch) coupled to the MINES thermodynamic database (https://geoinfo.nmt.edu/mines-tdb/) 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 ore-forming processes.

The workshop covered: 1) fundamentals of the GEM-Selektor code package and thermodynamic databases for simulating fluid-rock systems; 2) the GEMSFITS parameter optimization tool for optimizing thermodynamic properties against experimental data; 3) an overview of experimental advances in the study of aqueous complexes and mineral solubilities in hydrothermal fluids; 4) the stability and mobility of metasomatically induced and altered REE mineral phases in crustal rocks (e.g. monazite, xenotime, apatite, allanite, and titanite); 5) insights from field case studies of critical mineral deposits.
