Description :
A Holocene alluvial morphostratigraphy, based on geomorphological mapping, sedimentological analysis, soil development and radiocarbon chronology is presented for the semiarid Blanca basin in this natural park. Four morphosedimentary alluvial units were differentiated, which may correspond to two palaeogeographical stages. The established soil chronosequence supports the numerical chronology of the four units. Changes on the North Atlantic atmospheric circulation mode over Southern Europe may provide the key to explain the nature of alluvial activity during Holocene in Bardenas Reales.
