Abstract

The Cerro Cabrera and Sierra Cabeza Corda peridotite massifs (Calzadilla de los Barros, Badajoz) comprise serpentinites hosting podiform chromite mineralization and have been interpreted as part of an ophiolitic slab. The chromites are Al-rich and cristallized from a MORB-type melt. The subsolidus reequilibration with olivine depleted the chromite margins in Al and Mg. Later metamorphic alteration produced a enrichment in Te3+, resulting in the formation offerrichromite
