Three Late Pleistocene units (Qt1, Qt2 and Qt3) of gravel accumulation have been differentiated using geomorphologic mapping, sedimentological analysis and optically stimulated luminescence techniques. Chronological data show ages of 92, 52 and 15-21 ka respectively, which are closely related to cold climate signals at regional scale. Aggradation in braided channel systems was mainly controlled by increases in runoff and sediment supply}, title = {Morfoestratigrafía y cronología de registros fluviales del Pleistoceno superior en Bardenas Reales de Navarra: implicaciones paleoambientales}, title = {Morphostratigraphy and chronology of fluvial records during Late Pleistocene in Bardenas Reales of Navarra: palaeoenvironmental implications}, author = {Sancho, Carlos and Muñoz Jiménez, Arsenio and Rhodes, Edward and McDonald, Eric and Peña, José Luis and Benito, Gerardo and Longares, Luis Alberto}, }
