Cation distributions in transition metal oxide spinels can be determined thermoelectrically from room temperature to their melting points. A multiprobe apparatus facilitates the collection of data. Results for magnetite, divalent ferrospinels at low temperature, Fe3O4-MgFe2O4 at high temperature, trivalent ferrospinels, and Fe3O4-Fe2TiO4 at high temperature are presented. Cation distributions are calculated and tested against current thermodynamic models. Extension of the technique to other mineral solid solutions is considered.
