La Formación Frontada (Grupo Campóo) muestra numerosas estructuras relacionadas con la migración y precipitación de hierro en sus facies de orla aluvial distal y llanura de inundación. Estos rasgos pedogénicos están asociados con procesos de intenso lavado químico del sustrato y establecimiento de suelos hidromorfos. El análisis de estas estructuras ha permitido deducir cómo se generaron, y establecer un modelo genético para explicar su origen. Con base en ello, se han podido inferir unas condiciones climáticas de alta humedad y temperatura, similares al clima ecuatorial actual, bajo el cual se generaron los procesos de ferricretización 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
