Introduction to Pʜʀᴇᴇǫᴄ
This work was partly supported by NSF grant EAR-1926734, the endowment for the Haydn Murray Chair, and the Office of the Vice Provost for Research of Indiana University.
ᴘʜʀᴇᴇǫᴄ is a geochemical modeling software distributed by the U.S. Geological Survey and developed by David Parkhurst and Tony Appelo. It is written in the C and C++ programming languages and is designed to perform a wide variety of aqueous geochemical modeling calculations.
Here, the online version ᴘʜʀᴇᴇǫᴄ has new datasets diagenesis.dat and geothermal.dat, which have thermodynamic properties consistent with those in Zimmer et al. (2016) and allow ᴘʜʀᴇᴇǫᴄ calculations at elevated temperature and pressure.
