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.
