ThermoCodegen Fo-SiO2 database

ThermoCodegen v0.6.7 generated thermodynamic database for the Forsterite-SiO2 binary system developed by Lucy Tweed, 2021

This system is described by a custom Thermodynamic Database consisting of four phases, constructed from five endmembers.

The first phase is silicate Liquid constructed as an assymetric regular solution between two endmembers:

• Forsterite (Mg₂SiO₄^lq)

• Qz4 (Si₂O₄^lq)

where Mg₂SiO₄^lq is the forsteritic xMelts model and Qz4 is an endmember constructed from two moles of an xMelts SiO₂^lq model.

The next three phases are pure phases each constructed from a single endmember

• Olivine (endmember: Forsterite, Mg₂SiO₄^ol)

• Opx (endmember: Orthoenstatite, MgSiO₃^opx)

• pQz (endmember: polymorphic SiO₂, SiO₂^qz)

where pQz is constructed from a single polymorphic endmember (see below). All of the mineral endmembers are from (Berman, 1988)
