[ES] El registro de los tiempos geológicos en la sucesión estratigráfica es muy incompleto ya que los periodos de no deposición son más importantes que los de sedimentación. Durante estas interrupciones, estas discontinuidades, se producen alteraciones que modifican profundamente los caracteres sinsedimentarios. Son debidas a procesos pedogenéticos pero también a la acción de las aguas subterráneas. El resultado de las mismas produce una «continentalización~d~e las series, lo que ha llevado a errores en la interpretación de ciertas facies. El estudio de estas paleoalteraciones permite obtener conclusiones paleogeográficas y paleoclimáticas.
[EN] The record of geological time in stratigraphic successions is discontinuous because periods of norrdeposition are much longer than those of active sedimentation Weathering takes place during these breaks, deeply disturbing the sinsedimentary fabncs. These phenomena are mainly of pedogenetic origin, but also due to ground waters. The final result is a «continentalization» of the series, being that the cause of several erroneous interpretations of ancient sediments. The study of paleoweatherings give clues to paleogeographic and paleoclimatic interpretation.
