Resumen

Pleistocene to Holocene evolution of the lower Guadalquivir floodplain (SW Spain) is analyzed from a geoarchaeological approach. We especially study sedimentological data from the valley of the ancient Tagarete River, a small left tributary of the Guadalquivir which is now nolonger there. Our study suggests a transition from the Pleistocene to the Holocene with a triple sedimentary system. The sequence begins with a thick detritic series of upper Pleistocene alluvial gravels, including well-rounded stone tools of the Middle Paleolithic (1). The transit of this alluvial system to the Holocene facies occurs through a strong stratigraphic unconformity that gives way, first, to an organic sediment formation environment (lagoon) correlative with the end of the sea level rise in the mid-Holocene (2), and, subsequently (late Holocene), to a predominance of flooding deposits and emerging facies at the top of the sequenc
