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.
