total recalculation to feo and fe2o3


Alaska Volcano Observatory - Geochemistry

Handling iron values: When an analysis reports Fe2O3, we convert Fe2O3 to FeO with a conversion factor of 0.8998. We have adjusted the results for nearly all samples analyzed by inductively coupled plasma mass spectrometry (ICPMS) at Washington State University prior to 2007, correcting calibration errors that were present in the original data ...

Could I get the FeO and O2 value from the equation "FeO total = FeO + 0.8998*Fe2O3" or molar stoichiometric equation Fe2O3 = 0.5O2 + 2FeO? It is a dumb question, but I think it is important to know the stoichiometric calculation of FeO and Fe2O3 separation. Thank you for read. I would be greateful if I could get advice on that.
