Oxygen fugacity has been calculated for rutile–ilmenite assemblages from the reaction 2Fe2O3 (in ilmenite) C 4TiO2 (rutile) D 4FeTiO3 (in ilmenite) C O2. The equation log f O2 D 22:59 25925=T 3:09 log T C 0:0016535P C 48:836P=T 4 log a FeTiO3 C 2 log a Fe2O3 C 4 log a TiO2 , where T is in kelvin and P is in kbar, was derived from available thermodynamic data. The hypothetical end-member rutile–ilmenite reaction is located between the magnetite–hematite and Ni–NiO (NNO) buffers. The rutile… CONTINUE READING
