Le Quaternaire de la basse Somme; tentative de synthese

Abstract

Abstract The lower valley of the Somme river (northern France) contains a succession of interglacial deposits--fluviomarine sands, littoral bands, alteration zones, tuffs, periglacial deposits, loess, and coarse fluviatile alluvium--which can be correlated with the glaciations of the French Alps. The deposits range from pre-Guenz to post-Wuerm and are identified by their flora and fauna and the remains of prehistoric industries. Cross-sections illustrate the positions of the levels discussed.
