If magnetite is substituted by Cr the most stable configuration was found to be the one where all four Cr atoms are placed in the same cube thus forming "pairs" as in hematite The energy differences obtained between the most and the least stable structures are generally much higher in magnetite (122 8 kJ/mol) than in hematite

Microscopic studies in the reflected light permitted the detection of magnetite hematite and chromite in olivine serpentinite and true serpentinite Magnetite reveals typical optical characteristics (Ramdohr 1960) and is represented by two varieties primary (Pl I Fig 3 4 5) and secondary (Pl II Fig 1—5)
