Résumé
The analysis by electron microprobe allows the evaluation of the
quantity of Fe3+ ih spinels with considerable errors. The use of a
correction equation which is based on a the calibration of analyses with
an electron microprobe in relation to those carried out with Mossbauer
spectroscopy gives more precise evaluations of Fe3+. In fact, it allows
a calculation of the oxygen fugacity in peridotitic xenoliths. The
obtained results show that peridotites of the French Central Massif
crystallised under oxygen fugacities which were higher than those of the
Moroccan Anti-Atlas.
