This is a separator tag that divides the melts.out file. It is output every time a new "state of the system" is written.
Title for the run. Dummy if the input deck is created from within MELTS. Titles may be changed by editing the appropriate input (*.melts) file.
Temperature of the system in degrees C.
Pressure of the system in bars.
System oxygen fugacity in base 10 logarithm units.
System oxygen fugacity relative to the hematite-magnetite (HM), nickel-nickel oxide (NNO), quartz-fayalite-magnetite (QFM) and iron-wustite (IW) oxygen reference buffers.
One or more reaction path constraints:
fo2 path = HM Reaction path constrained to evolve along the hematite-magnetite oxygen buffer.
fo2 path = NNO Reaction path constrained to evolve along the nickel-nickel oxide oxygen buffer.
fo2 path = QFM Reaction path constrained to evolve along the quartz-fayalite-magnetite oxygen buffer.
fo2 path = IW Reaction path constrained to evolve along the iron-wustite oxygen buffer.
fo2 path = QFM+3 Reaction path constrained to evolve along the quartz-fayalite-magnetite oxygen buffer displaced by 3 base 10 log units in the positive direction.
fo2 path = QFM+2 Reaction path constrained to evolve along the quartz-fayalite-magnetite oxygen buffer.
fo2 path = QFM+1 Reaction path constrained to evolve along the quartz-fayalite-magnetite oxygen buffer.
fo2 path = QFM-1 Reaction path constrained to evolve along the quartz-fayalite-magnetite oxygen buffer.
fo2 path = QFM-2 Reaction path constrained to evolve along the quartz-fayalite-magnetite oxygen buffer.
fo2 path = QFM-3 Reaction path constrained to evolve along the quartz-fayalite-magnetite oxygen buffer.
Fractination Solid phases are removed from the system at each step in reaction progress.
Isenthalpic Path The system evolves on the constraint of fixed total enthalpy.
Isentropic Path The system evolves on the constraint of fixed total entropy.
Isochoric Path The system evolves on the constraint of fixed total volume.
Assimilation The reaction path includes the assimilation of one or more phases.
Heading for section of melts.out file reporting properties of the liquid phase.
Mass of the indicated phase(s) in grams.
Density of the indicated phase(s) in grams/cc.
Viscosity of the liquid reported as the base 10 logarithm of the value in units of poise.
Thermodynamic Properties of the phase(s) on an extensive basis (value corresponding to the mass indicated). G is the apparent Gibbs Free Energy of formation reported in Joules. H is the apparent Enthalpy of formation reported in Joules. S is the absolute entropy reported in Joules per degree Kelvin. V is the absolute volume reported in cubic centimeters. Cp is the absolute isobaric heat capacity reported in J oules per Kelvin.
The chemical composition of the liquid phase is reported in wt% oxides.
Phases present in the system other than the silicate melt are designated by an appropriate phase name. The names should be self-explanatory. Multiple phases of the same name denote the existence of a miscibility gap for that phase. Examination of p hase compositions in these circumstances yields tie-line compositions.
The composition of each phase is reported as a formula. Standard usage is followed as much as possible. Consult the MELTS reference for more information on models for complex mineral solid solutions.
The composition of each mineral solid solution is reported in terms of endmember thermodynamic components. These are not endmember mineral species, but are rather a linearly independent set of compositional variables chosen to formulate the thermodynamic model for the mineral. Consequently, it is not uncommon for a mineral endmember to have a negative concentration in a particular phase. For more information and examples consult the MELTS reference for a discussion on m odels for complex mineral solid solutions.
This heading designates entries for the sum of all of the solid phases in the system. Note that these entries do not include the amount of material fractionation from the system.
The viscosity of the system (i.e., the crystal-liquid mixture) is estimated from the liquid viscosity using an algorithm that assumes the system becomes rigid at 50% crystallization.
