Datations U/Th (TIMS) et ¹⁴C (AMS) des stalagmites de la grotte Chauvet (Ardèche, France) : intérêt pour la chronologie des événements naturels et anthropiques de la grotte

Eight stalagmites, two flowstones and several pieces of charcoal found trapped under the speleothems from the Chauvet cave (Vallon-Pont-d'Arc, Ardèche, France) have been dated by radiometric mass spectrometric methods (U/Th et ¹⁴ C). Results give accurate ages for some geological features of the cave, and, for some of them, confirm the old ages of the prehistoric charcoal. They also indicate the timing of the climatic periods that were favourable to the stalagmites growth.
