Apports de l’archéobotanique à la compréhension de la Source des Roches, Chamalières (Puy-de-Dôme)

Revue Archéologique du Centre de la France, 2008
Unusually high levels of tree pollen were revealed by palynology on the site of the Source des Roches in Chamalières (Puy-de-Dôme) for the very beginning of the Roman period. The site had yielded more than 3500 wooden offerings in the early 70s.
