La stratigraphie du Pleistocène supérieur et de l'Holocène dans le Golfe de Gascogne: Essai de synthèse des critères actuellement utilisables

Using analysis of marines cores from the Bay of Biscay as a basis, a system of different episodes of the Upper Pleistocene and the Holocene in the area of the Bay is presented. These episodes are characterized by several sedimentological and micropaleontological observations and particularly by the analysis of the coiling ratio of a few species of planktonic foraminifera. From the cores it is thus possible to determine the Holocene, the Würmian with its four glacial and three interglacial stages, and, at the base of the last glacial stage, the Riss-Würm interglacial or its upper level.
