Previous age assignments by other authors envisage that these conglomerates belong to the MIS 7 (Mindel-Riss interglacial).For the first time, single-phase and some polyphase cements were AMS 48,000 years BP.Datations AMS du radiocarbone des ciments carbonatés des conglomérats alluviaux fini-pléistocènes de la rivière Verdouble.Implications paléoenvironnementales relatives au site paléolithique de Tautavel (Pyrénées-Orientales) The Pleistocene alluvial conglomerates of the Verdouble River valley, close to the famous Palaeolithic site of Tautavel, were the object of lithologic determinations including microtextural analysis intended to define their provenance, their sedimentary facies and their calcite cement.Note: Many of our articles have direct quotes from sources you can cite, within the Wikipedia article! The method is considered by some to be experimental, and it is not as widely used in archaeology as other chronometric methods such as radiocarbon dating. [6] Kindall, Sheldon 1997 The Oxidizable Carbon Ratio (OCR) Technique: A New, Low-Cost Dating Method. New South Associates, Inc., Stone Mountain Georgia. Oxidizable carbon ratio dating is a method of dating in archaeology and earth science that can be used to derive or estimate the age of soil and sediment samples up to 35,000 years old. Prehistoric and Historic Excavations at Site 9Gw347, Annistown Road Improvement Project, Gwinnett County, Georgia.

Several pedons of the Shulie and Westbrook soils were observed and analyzed to determine the degree of their pedogenic development in order to estimate the relative ages of the two tills in which these soils had developed.

Lateral erosion by floods of the Verdouble probably destroyed the Palaeolithic soils and settlements downstream of the Gouleyrous Gorges: the limited preserved evidence is exactly situated upstream at the confluence of the Vingrau Stream and Verdouble River.

Les conglomérats alluviaux pléistocènes de la vallée du Verdouble, proches du célèbre site paléolithique de Tautavel, ont fait l’objet de déterminations lithologiques des galets afin de déterminer leur provenance et d’analyses microstructurales des ciments calcitiques préliminaires aux datations AMS du C.

They testify to a rather late karst-induced excavation of the Gouleyrous Gorge and consequently to the relatively recent connection between the upstream and downstream basins of the Verdouble River.

Consequently, this connection did not exist at the time of the Tautavel Man (450,000 years BP).

Rates of dry deposition of pedogenically derived elements were high relative to forests further to the east, while rates of deposition of anthropogenically derived elements were low in comparison to these same forests.
