La séquence lacustre du maar d’Alleret (Massif Central, France) : téphrochronologie et évolution paléoenvironnementale en Europe occidentale au début du Pléistocène moyen

Abstract: Le maar d'Alleret (Massif central, France) contient une séquence lacustre couvrant les stades isotopiques marins (SIM) 17 à 15. La partie étudiée, comprise entre 40,5 et 24,25 m de profondeur, enregistre la présence de téphras du Mont Dore (phase Sancy) qui permettent d'établir une téphrochronologie à partir de datations 40 Ar/ 39 Ar laser comprises entre 683 ± 5 et 718 ± 6 ka. Les analyses géochimiques et minéralogiques de ces téphras montrent une mésostase vitreuse à composition trachytique à rhyolitique. De… Show more

“…Besides all these studies dealing with the Late-Glacial and Holocene vegetation and landscape changes in the Massif Central, the Velay volcanic craters also provided rare long Late-Pliocene and Pleistocene pollen sequences (Ablin, 1991;de Beaulieu and Reille, 1992;Degeai et al, 2013;Reille et al, 1998Reille et al, , 2000Argant and Bonifay, 2011;Argant, 2022/in press). Interestingly, only few summarizing reviews were published on the past Quaternary vegetation and landscape changes in the Massif Central (Reille et al, 1992;Reille, 2013) summarizing 23 years of palynological work by the author, including a large number of Massif Central sites.…”
