The equilibrium high temperature cation intersite distributions in iron-bearing minerals which exhibit small polaron "hopping" conduction can be determined by a technique which combines electrical conductivity and Seebeck effect. The procedure is demonstrated for ferrospinels (Fe3O4) - FeAl2O4 and Fe3O4 - CoFe2O4) and applied to the olivine Fe2SiO4 - Mg2SiO4 system.
