RT Journal Article T1 A Late Pleistocene coastal plain pertaining to MIS 5 in the Gulf of Cádiz (mouth of the Guadalquivir River, SW Iberia) A1 Rodríguez Ramírez, Antonio A1 Gracia Prieto, Francisco Javier A1 Morales González, Juan Antonio A1 García Díaz, Diego A1 Mayoral Alfaro, Eduardo AB The geomorphological, sedimentological, topographical and chronological analysis of a large area located on theleft bank of the Guadalquivir estuary (SW Iberian Peninsula), has enabled an extensive Late Pleistocene coastalplain to be defined, featuring a series of littoral strands. These rest uncomfortably on a rocky basal unit (BU) fromthe Lower Pleistocene, with an age of 1.1 Ma BP, showing shore platform morphology. The Late Pleistocenecoastal plain presents a facies system where three stratigraphic units have been defined (CPU 1, 2 and 3). Allunits indicate the progradation of a littoral barrier system towards the sea and correspond to highstand MIS 5e2.Above these is located a red sands unit (RSU), interpreted as alluvial deposits, and indicative of a gradual drop insea level and a progressive continentalization of the area. This unit was affected by karst processes. According tothe topographic elevation of these littoral strands, the relative tectonic stability of the area and the regionalcorrelation, the elevation of the deposits, about 7–8 m above the current mean sea level, could be considered as areasonable representation of the eustatic level during MIS 5e2. This data could be useful for comparison withother regional determinations of MIS 5 sea level in Western Europe, and for future predictions of relative sealevel rise in the area.
