Minerals Database

GCE2 is a thermodynamic and properties database used in applications such as geochemistry, geophysics, hydro-metallurgy, aqueous chemistry, and environmental chemistry.

This database contains critically assessed temperature-, pressure-, and composition-dependent data for minerals (silicates, oxides, hydroxides, halides, carbonates, sulfides, sulfates, nitrates, phosphates, and so on).

The Birch-Murnaghan model for the pressure dependence of EOS is used. The applicable temperatures range from 298.15 K to about 6000 K and pressures from 1 bar to 1000 kbar (100 GPa). The compounds are treated as either stoichiometric or solution phases. A metallic liquid solution phase is included, but currently there is no data for melt mixture phases with, for example, oxide/silicate/carbonate/sulfide/sulphate/… species (of neutral or charged forms).

This database is compatible with almost all other thermodynamic and properties databases available from Thermo-Calc Software. Especially when combined with the AQS database, GCE2 can be applied to investigate complex heterogeneous interactions among minerals, aqueous solutions, and sub-/super-critical H2O over a wide temperature – pressure – composition range.
GCE2 was developed to be used with Thermo-Calc and all available SDKs.

GCE2 does not have a corresponding mobility database.
