Petrological Modeling Tools

1. MELTS Melts is a software package for modeling crystallization of magmatic systems.
2. MELTS Calculator To compute Thermodynamic Properties and/or Component Transformations of Mineral Solid Solutions.
3. PELE & IRIDIUM PELE - a version of the silicate liquid crystallization MELTS software. IRIDIUM - a program to model melt infiltration and reaction.
4. QUILF95 Best program around for calclulating intensive variables; you'll need to scroll down the page a bit to find the download.
5. ConFlow A model that calculates flow properties (pressure, vesicularity, and some 35 other parameters) as a function of vertical position within a volcanic conduit during a steady-state eruption.
6. EC-RAFC A self-consistent formulation of energy, mass and species conservation for a magma body undergoing concurrent assimilation-fractional crystallization, with or without recharge.
7. KWare A variety of programs for modeling melt properties (also volcanological programs such as SFT).

8. SolvC






A windows based interactive graphics program package for calculating the ternary feldspar solvus and for two-feldspar geothermometry.
9. GTB&more Program GTB was written to perfom calculations of geothermometers and geobarometers and to plot the results as lines of constant equlibrium constant on a P-T diagram.
10. MIXNFRAC Roger Nielsen's phase equilibria programs for modeling magmatic differentiation are described in Geochimica Cosmochimica Acta and in Reviews of Mineralogy, vol. 24.
11. THERMOCALC THERMOCALC is a thermodynamic calculation software package for tackling mineral equilibria problems.
12. WEBINVEQ WEBINVEQ solves the inverse chemical equilibrium problem, i.e. giventhe activities of end-members of coexisting minerals, the program computes a least-squares estimate of the pressure and temperature of equilibration of the minerals.
13. PETRO.CALC.PLOT Extensive (free) Excel macros for plotting petrologic data. Also available from:
14. CIPW Norm Calculator A good Excel Macro.
15. HB-PLAG hbplag is a public domain application for calculating hornblende-plagioclase geothermometry for the Macintosh,
DOS and Windows. It is based on the thermometers of Holland and Blundy (1994, Contrib. Mineral. Petrol., v. 116).
16. BIGD BIGD is designed to calculate mineral-melt partition coefficients for mafic igneous systems ranging from alkali and tholeiitic basalt to andesites and dacites.
17. TERNPLOT Excel macro for plotting ternary diagrams.
18. GERM Links Links to many petrologically useful programs.
19. Uni-Geochem Many useful petrology-oriented programs; the most useful programs are AFC.traces, AFC.isotopes, and Mixing.isotopes (Excel templates); also includes downloadable databases of isotope data.
