This site hosts a computer application for thermobarometry. The program calculates pressures and temperatures for garnet, cordierite, spinel, sillimanite/kyanite, quartz anhydrous or hydrous pelitic assemblages. The user enters cation values for each mineral, and the model generates pressure vs. temperature graphs or data tables of the calculated isopleths. The program is derived from the shareware NICHOLS program, which is available in either Macintosh or PC friendly formats.
