Аннотация: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.
