One of the gravel sheets of the alluvial complex of the "Basse Somme" shows some characteristics which are considered as witness of a marine influence. This gravel sheet, named Croix l'Abbé Formation was deposited about a height of 25 m during a cold climatic episode of the Lower Pleistocene ; relationships with the terraces of the Somme between Pinchefalise and Saigneville are discussed here. One of the writters (De H.) describes the associated Palaeolithic artefacts.Une des nappes du complexe alluvial de la Basse Somme présente des caractéristiques qui sont interprétées comme témoignant d'une influence marine. Cette nappe, décrite ici sous le nom de Formation de Croix l'Abbé, s'est mise en place vers 25 m d'altitude au cours d'un épisode ...
