AbstractIn this work, preliminary chronostratigaphic features of the Upper Pleistocene-Holocene morphosedimentary alluvial unit covering the bottom of the Bardena Blanca depression are described. This unit is made up by 1) gravels and sands related to a braided channel system, 2) laminated sands and clays accumulated in distal flats of alluvial fans and 3) clays and gypsums corresponding to a playa-lake environment. According the first chronological data supplied by OSL and 14C the age of this sequence ranges between 18 and 5 ka. The prevailed paleoclimatic conditions were cold and humid during Last Glacial Maximum-Oldest Dryas and arid during Lower Holocene.
