## Available thermodynamic datasets
The MAGEMin algorithm is general and can be used with any thermodynamic database that are hardcoded for speed reasons. Presently the igneous (Holland et al., 2018) and the metapelite (White et al., 2014) database are available.
The MAGEMin algorithm is general and can be used with any thermodynamic database that are hardcoded for speed reasons. Presently the igneous (Green et al., 2023, updated versions of Holland et al., 2018 and Tomlison et al., 2021), the ultramafic (Evans & Frost, 2021) and the metapelite (White et al., 2014) database are available.

**Igneous thermodynamic dataset**

**Igneous database**
The hydrous mafic melting model of Holland et al. 2018 can be used to simulate the fractional crystallisation from a hydrous basalt to a felsic melt.

==================

MAGEMin (Mineral Assemblage Gibbs Energy Minimization) is a parallel C library callable from any petrological/geodynamic tool. For a given set of pressure, temperature and bulk-rock composition MAGEMin uses a combination of linear programming, extended Partitioning Gibbs free Energy and gradient-based local minimization to compute the most stable mineral assemblage
