This program is designed to compute a given mineral chemical analysis in terms of a specific collection of molecular members or molecular end members. The method employed is quite general and may be extended to a mineral chemical analysis composed of any number of oxides. The program as written, however, is limited to those analyses composed of at most seven oxides. The program is written in Fortran IV language for the Philco 2000 computer.
