[1] The program adiabat_1ph is a simple text-menu driver for subroutine versions of the algorithms
MELTS, pMELTS, and pHMELTS [Asimow et al., 2004; Ghiorso et al., 2002; Ghiorso and Sack, 1995]. It
may be used to calculate equilibrium assemblages along a thermodynamic path set by the user and can
simultaneously calculate trace element distributions. The MELTS family of algorithms is suitable for
multicomponent systems, which may be anhydrous, water-undersaturated, or water-saturated, with the
options of buffering oxygen fugacity and/or water activity. A wide variety of calculations can be performed
either subsolidus or with liquid(s) present; melting and crystallization may be batch, fractional, or
continuous. The software is suitable for Linux, MacOS X, and Windows, and many aspects of program
execution are controlled by environment variables. Perl scripts are also provided that may be used to
invoke adiabat_1ph with some command line options and to produce output that may be easily imported
into spreadsheet programs, such as Microsoft Excel. Benefits include a batch mode, which allows almost
complete automation of the calculation process when suitable input files are written. This technical brief
describes version 1.04, which is provided as ancillary material. Binaries, scripts, documentation, and
example files for this and future releases may be downloaded at http://www.gps.caltech.edu/asimow/
adiabat. On a networked computer, adiabat_1ph automatically checks whether a newer version is available.
