fO2melt : calculate fO2 of melts from chemical analyses

---

fO2melt is a program which takes rock/glass analyses in the form of oxide weight percent and calculates the oxygen fugacity from supplied Fe2O3 wt%. logfO2 is given relative to QFM, NNO or CCO buffers. The bulk composition is recalculated for input to THERMOCALC and logfO2 is also calculated for a range in Fe3/FeTot to help determine the Fe2O3 needed for a desired fO2.
