Description
Summary:[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.
