Dear All,

We will host a 2 days NSF-sponsored workshop at Goldschmidt on numerical modeling methods of hydrothermal fluid-rock interaction, thermodynamic databases, and experimental methods with applications to ore deposits and crustal metasomatism. This workshop will be useful for everyone who wants to learn about GEMS for the interpretation of natural systems and also evaluation of experimental data and thermodynamic properties of minerals and fluids.

Metasomatism and ore deposits in the Earth’s crust: experimental and modeling methods 

Saturday 11th August 09:00 - Sunday 12th August 17:00 
Contacts: Alexander P. Gysi (Colorado School of Mines), Daniel Harlov (GFZ Potsdam), Dmitrii A. Kulik (PSI, Switzerland), George D. Miron(PSI, Switzerland)

The workshop is intended for graduate students, researchers, and professionals whom want to learn how to apply the GEMS code package (http://gems.web.psi.ch) to geochemical modeling, as well as learn about how to use current experimental methods regarding fluid-rock equilibria 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 ore-forming processes. The workshop will cover: 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 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 REE mineral deposits. The first day of the workshop will cover 1) and 2). Here participants will learn the tools necessary to simulate fluid-rock equilibria at high P-T conditions and how to retrieve the parameters for geochemical modeling. These tools include the GEMS code package, which is supported by a tutorial series for different ore-forming processes (e.g., Greisen tin deposits), and by the MINES thermodynamic database (http://tdb.mines.edu). The second day of the workshop will cover 3) and 4). Here participants will be introduced to the experimental methods and field examples necessary for studying the solubility and speciation of REE in crustal fluids. 

We look forward seeing you there! Please pass this one to your students and colleagues. 

Cheers,

Alex, Dan H, Dmitrii and Dan G.
