sᴜᴘᴄʀᴛ is a software package to calculate thermodynamic properties for minerals, gases, aqueous species, and reactions at high temperatures and pressures. It is a FORTRAN program written originally by students and associates of Professor H.C. Helgeson at the University of California - Berkeley, and was updated by Jim W. Johnson, Eric H Oelkers and Everett Shock up to 1992 (Johnson et al., 1992). The original program uses the internally consistent database of minerals and gases from Helgeson et al. (1978). The Maier-Kelley heat capacity formulation was used for minerals.
For this version of sᴜᴘᴄʀᴛ (sᴜᴘᴄʀᴛʙʟ), we used a more recent mineral database of Holland and Powell (2011) and modified the computer code accordingly to accommodate the different heat capacity function, volume as a function of temperature and pressure, and mineral phase transition using the Landau model (Holland and Powell, 1998). We also added more species to the database. This includes arsenic minerals and aqueous species, aluminum species from Tagirov and Schott (2001), aqueous silica from Apps and Spycher (2004) and Stefasson (2001), and dawsonite from Benezeth et al. (2007). The stated temperature and pressure ranges for aqueous species are from 1 to 5000 bars and 0° to 1000°C, but for minerals the ranges exceed the original limits stated in Johnson et al. (1992), but vary for individual species. Please check carefully.

We strongly recommend citing together with Johnson et al. (1992) when using sᴜᴘᴄʀᴛʙʟ:
Johnson, J.W., Oelkers, E.H. and Helgeson, H.C. (1992) SUPCRT92 - A software package for calculating the standard molal thermodynamic properties of minerals, gases, aqueous species, and reactions from 1-bar to 5000-bar and 0°C to 1000°C. Computer and Geosciences 18:899-947.
The computer code and database presented here was put together to accommodate the needs of our departmental colleagues and students in petrological research, and was a collective effort by many of Zhu’s students over several years: Peng Lu (now at Saudi Aramco), Yanyan Chen (now at Petro China), Guanru Zhang (now a professor at Chengdu Univ. of Technology), Kurt Zimmer (now a Data Science Manager at Wayfair), Yilun Zhang (now a senior scientist at InterTek environmental services), and Kevin Tu (undergrad in IU School of Informatics, Computing, and Engineering). Many parts are untested, and the users assume all responsibilities. We will continue making corrections. Kindly send comments and corrections to Chen Zhu at firstname.lastname@example.org.
There is no Mac version of sᴜᴘᴄʀᴛ due to issues compiling Fortran to the many different versions of OSX, please use the online version instead.
