Élaboration d’un cadre chronostratigraphique pour le Pléistocène de la région Centre-Val de Loire (France) : présentation du projet de recherche et des premiers résultats

Abstract : Over the past years, the preventive archaeological investigations carried out by the French institute Inrap in the Centre-Val de Loire Region of France, have revealed Pleistocene sequences of silt in the Beauce area and of alluvia southward in the Loire valley around the city of Orléans. The stratigraphic correlations observed between the different sequences of each area have revealed the need to establish a regional chronostratigraphic framework for this period, little known until now. A research group, supported by Inrap and made up of geomorphologists and prehistorians working within the framework of preventive archeology, was thus constituted in order to propose a first synthesis of the studied stratigraphies. In the absence of absolute dating, this work relies mainly on facies analogies with reference sequences, established in the Centre-Val de Loire region for alluvial records and in the north of France for silt records. The medium-term objectives are to define regional benchmark horizons that enable the identification of pleistocene stratigraphic sequences from the archaeological survey phase, with a view to the detection of Palaeolithic sites as well as to understand how the major pedological and morphogenic Pleistocene episodes appear within the silt and alluvial superficial formations.
