Program GTB: GeoThermoBarometry

Introduction to Program GeoThermoBarometry

Program GTB was written to perfom calculations of geothermometers and geobarometers and to plot the results as lines of constant equlibrium constant on a P-T diagram. The goal was to make a program that was relatively easy to use that would incorporate all published geothermobarometers.

Input to the program is via a dialog box (keyboard input) or data file (tab delimited format), which can be created using most spread sheets.

An extensive manual describing the options comes with the program in PDF format (Acrobat Reader required).

The program is being updated regularly, so keep posted for new versions.
