Gt- and Sp-Oxybarometry
GtfO2 and SpfO2, two programs to calculate fO2 of mantle Garnet peridotites and Spinel peridotites from mineral analyses.
GtfO2 and SpfO2 are programs which takes mineral analyses in the form of oxide weight percent. Errors are propagated from the probe data to the final fO2 values. These programs follow the method outlined in Miller, Holland & Gibson (2016, J. Pet) and use multi-reaction oxybarometry to yield least squares estimates of fO2.
