Environnements et occupations paléolithiques d'Italie centrale : la longue séquence pléistocène moyen de Valle Giumentina

Abstract : An integrated multidisciplinary study (sedimentology, geochemistry, micromorphology, biomarker analysis, geochronology and tephrochronology) was undertaken on the sedimentary infill of the Valle Giumentina basin (Abruzzo, Italy). In the 1950s an outstanding archaeological sequence, composed of nine human occupation levels ascribed to Acheulean eand Clactonian, was discovered inside this continental succession, 45m deep. Since then, the site is a reference for the definition of the Italian and European Lower Palaeolithic. This study depicts an evolution of the Valle Giumentina basin in four phases during the Middle Pleistocene, on a time span comprised between 600 and 400 ka, corresponding to MIS15-MIS12. The comparison with the contemporaneous palaeoenvironmental archives highlights that Valle Giumentina is a high-precision record and that its evolution is close to the East-Mediterranean sites. The new chronostratigraphic framework built by our results allows to precise the chronology of each archaeological level and to reconstruct the environmental context of the Palaeolithic human occupations.
