Géoarchéologie des cavités du Cerro Benitez, région d’Última Esperanza, Patagonie chilienne

Le projet GEOCEBE s’inscrit dans une collaboration franco-chilienne associant archéologie, paléontologie, géoarchéologie et géomorphologie. L’objectif général du projet est de mieux comprendre la géoarchéologie de différents gisements en grottes et abris sous roches du Cerro Benitez (Patagonie chilienne). Les objectifs spécifiques visent à: 1) mieux comprendre les processus de formation des sites à la transition Pléistocène-Holocène, 2) en étudiant les dépôts et 3), le contexte géomorphologique. Ce travail permettra notamment de mieux saisir la taphonomie des vestiges des taxons qui vont disparaître à la fin du Pléistocène. L’utilisation des nucléides cosmogéniques pour dater des blocs erratiques en marge des sites fouillés permettra: 1) de mieux documenter l’évolution géomorphologique locale, 2) de caler chronologiquement le retrait des glaces et 3), l’ouverture des cavités, paramètres déterminant pour la colonisation animale et les premières implantations humaines paléoindiennes.

Geoarchaeology of caves from Cerro Benitez, Última Esperanza, Chilean Patagonia

The GEOCEBE project is part of a Franco-Chilean collaboration involving archaeology, palaeontology, geoarchaeology and geomorphology. The main objective of the project is to better understand geoarchaeology of different caves and rock shelters of Cerro Benitez (Chilean Patagonia). The specific objectives are to: 1) understand the site formation processes during the Pleistocene-Holocene transition, 2) study new archaeological deposits and 3), characterize the geomorphological context. This work aims to give a more accurate understanding of the taphonomy of remains from animals that disappeared at the end of the Pleistocene. Cosmogenic nuclides dating of glacial boulders sampled next to excavated sites will allow to document: 1) the Late-Pleistocene geomorphological evolution, 2) the chronology of local ice retreat and 3), the opening of the cavities, which are all important factors for both animal colonization and first Palaeoindian human settlements.
