| Phase Equilibrium Calculations (MIXFRAC) | |
MIXFRAC is a code for phase equilibrium calculations for igneous systems based on trace element constraints. With the subprograms MIX3 and BLF one can calculate major- and trace-element differentiation
trends for crystallizing magmas. The programs have numerous options, including assimilation of a second material, assimilation of boundary layer material, and randomize the mixing and sampling parameters in order to create a more realistic synthetic data set.

| Modeling of Partition Coefficients (BIGD) | |
BIGD is designed to calculate mineral-melt partition coefficients for mafic igneous systems ranging from alkali and tholeiitic basalt to andesites and dacites. The building blocks for this program are mineral-melt
expressions for the major minerals. The necessary input data are the major element composition of the mineral and the melt, plus the temperature. Executable files of BIGD for the PC are included in the package, as well as its source code
that should be compatible with most FORTRAN compilers on other platforms.
