Short summary
We experimentally investigated the behavior of chrome in high-pressure post-spinel oxide phases. Only minor amounts of Cr can be incorporated into Fe5O6. But there is full solid solution between Fe4O5 and Fe2Cr2O5 and Mg2Fe2O5 and Mg2Cr2O5, in spite of a phase transition occurring in the middle of the compositional range. Our results provide further constraints on the formation of such oxide phases in extraterrestrial materials and inclusions in natural diamonds.
