pygcc Logo

A tool for thermodynamic calculations and geochemical database generation

pyGeochemCalc Documentation License: GNU General Public License v3.0

pyGeochemCalc (pygcc) is a python-based program for thermodynamic calculations and producing the Geochemist’s Workbench (GWB), EQ3/6, TOUGHREACT, and PFLOTRAN thermodynamic database from ambient to deep Earth temperature and pressure conditions

pygcc is developed for use in the geochemical community by providing a consolidated set of existing and newly implemented functions for calculating the thermodynamic properties of gas, aqueous, and mineral (including solid solutions and variable-formula clays) species, as well as reactions amongst these species, over a broad range of temperature and pressure conditions, but is also well suited to being modularly introduced into other modeling tools as desired. The documentation is continually evolving, and more examples and tutorials will gradually be added (feel free to request features or examples; see Contributing below).


PyPI Compatible Python Versions pygcc downloads

$ pip install pygcc


Check out the documentation for galleries of examples General Usage, Integration with GWB and Integration with EQ3/6. If you would prefer to flip through notebooks on Bitbucket, these same examples can be found in the folder docs/.
