We will be hosting a free online workshop January 12-13, 2026, to introduce a new python package called PetThermoTools that can be used to run thermodynamic calculations in rhyoliteMELTS, pMELTS, and MAGEMin (Holland models) in Python, getting around a lot of the stability issues of MELTS in particular and providing speed improvements through the use of parallel processing. It can do mantle melting, fractional or equilibrium crystallization, phase diagrams, degassing and much more. Feel free to share this announcement broadly as well as signing up yourself!
