Phase equilibria in the FeMnTiO system for the compositions Fe0.297Mn0.097Ti0.606O

This paper reports equilibrium-phase data for the FeMnTiO system at oxygen fugacities between 10^?18.2 and 10^?10.0 atm and at temperatures between 1249 and 1514K. An equilibration-and-quench method was used, and the oxygen fugacities were controlled with mixtures of hydrogen and carbon dioxide. The phase relations are presented on a log f_O2 vs $\text{1}\text{T}$ diagram and are discussed interms of the phase relations in the two systems FeTiO and MnTiO.
