Abstract

The stratigraphy and sedimentology of the Q3 middle terrace alluvial sequence in the lower Tagus river valley, were studied near the village of Alpiarça, approximately 40 km upstream from the estuarine area. Two main stratigraphic units were recognized, separated by an important uncomformity. Within the Upper Sands unit (US) are several paleolithic archaeological sites. TL/OSL dating of sandy-silty sediments, though imprecise, support archaeological evidence pointing to an age of 150,000 to 70,000 yr B.P. for the US unit
