Multiple environmental change at the time of the Modern Human passage through the Middle East: First results from geoarcheological investigations on Upper Pleistocene sediments in the Wadi Sabra (Jordan)

摘要: Upper Pleistocene sediments at Wadi Sabra (Ma’an District, Jordan) were geoarcheologically investigated from 2008–2010. The valley system, situated east of the Dead Sea Rift and south ancient Nabataean capital Petra, has preserved sedimentary deposits which are connected with several Paleolithic sites. First results sedimentological geochemical analysis supported by archeological radiometric dating provide evidence fluvial fluvio-eolian sedimentation during Marine Isotope Stage (MIS) 3 2 least 38 ka to 18 ka, followed one erosional event that finally determined recent morphology. Several calcretes, buried surfaces initial soil horizons indicate phases landscape stability potentially moister climatic conditions than today. Inferred favorable environment time allowed for human occupation attested throughout cultural stages Initial, Early, evolved early Epipaleolithic, thus illustrating occurrence Homo sapiens in Near East. Field work is expected further elucidate Out Africa II movement our species, leading modern humans Europe, possibly via Middle East Balkan Peninsula, both regions now under comparative investigation Cologne-Aachen B1 project group CRC 806.
