Résumé

The Frontada Formation (Campóo Group) presents an important amount of structures related to the migration and precipitation of iron in its alluvial floodplain sedimentary record. These pedogenical features are associated with processes of intense chemical weathering of the substrate and establishment of hydromorphic soils. The analysis of these structures has allowed us to deduce how they were generated, as well as to propose a genetic model to explain their origin. This model suggests a context of high climatic humidity and temperature, similar to the nowadays equatorial climate, under which the ferricretization processes occurred.
