| description | The geomorphological and sedimentological study makes it possible to distinguish several superficial formations preserved in the Belinois depression. The lower fine sands come from the alteration of Jurassic marl-limestone whereas the upper sands issue from Cenomanian outlying sands and were brought by wind during the last glaciation period. A clay sand bed coming from pedogenetic process and, in places, from clay sand colluvial materials, lie between the two formations. The thinness of superficial formations on the slopes and in the vale bottoms testifies the efficiency of river erosion during the periods of incision. |
