Ilmenite an overview ScienceDirect Topics

Unlike chromite, phase relations do not support crystallization of ilmenite and/or titanomagnetite without simultaneous crystallization of pyroxene and plagioclase. It is therefore not feasible that such concentrations can be achieved by crystal accumulation alone since this would require an extremely efficient sorting mechanism.
