MAGNETITE ACTIVITIES ACROSS THE MGAL2O4-FE3O4 SPINEL JOIN, WITH APPLICATION TO THERMOBAROMETRIC ESTIMATES OF UPPER MANTLE OXYGEN FUGACITY

The activity of Fe3O4 component in MgAl2O4-Fe3O4 spinels has been measured at 900° and 1000° C and 1 atm total pressure using a zirconia oxygen electrolyte. As previously reported for the dilute Fe3O4 concentration region (Mattioli and Wood 1986a), magnetite activity at 1000° C is greater than at 90...
