Abstract: Through chemical, mineralogical and geomophorlogical analysis, the ferruginous crusts in Calatrava are interpreted as Pliocenous and Pleistocenous deposits (alluvial fans, fluvial terraces, colluviums, accumulative glacis, etc.) cemented by ferrous oxides and hidroxides (hematite and geothite), by a lateral movement of hot springs loaded with dissolved iron, probably under a very extreme mediterranean paleoclimate, which has governed this area since the lower Pliocene until the upper Pleistocene, without any lateritic weatherings being detected in any case.
