Nouvelles recherches sur le gisement villafranchien de Seneze (Haute-Loire, France)

Abstract

Abstract Examination of a section of the core taken from a boring in the center of the Villafranchian Seneze lake has provided additional data on this classic locality. Variations observed in the pollen content are used to delineate a series of four separate climatic oscillations of alternating temperate and cool periods. The deposits represented in the core were laid down during the Villafranchian in a fresh-water medium as indicated by the presence of pollen from fresh-water aquatic plants and from Botryococcus. Pollen diagrams are included.
