| Abstract | | The southern Pampas of Buenos Aires comprises three main environmental units: the Tandilia and the Ventania ranges and the Pampa Interserrana. Several late Pleistocene sites are located either in quartzite rockshelters or near by to rock outcrops in the Tandilia range whereas few sites were found in fluvial settings of the Pampa Interserrana and none have been reported in the Ventania range so fan These early human groups occupied the region during the late Glacial, most of the radiocarbon ages are comprised between the 11,000 and 10,000 14C yr interval BP Paleogeographically, the region extended eastward because the sea-level was about 100-120 m below the present one. The variable reliability of the radiocarbon dates along with the loll stratigraphic resolution of the archaeological records, do not permit a precise reconstruction of the environmental and climatic conditions of that time interval. Pedogenesis and the biota substantially modified the records and played major roles as site formation processes. To date, the strategy of prospecting the late Pleistocene sites can be oriented by the landscape reconstruction of the southern Pampas. | | | | Keywords | | Geoarchaeology - Late Pleistocene - Early Holocene - Southern Pampas - Argentina - Paleoclimates - Paleosols | | |
