The gravels tend to be strongly imbricated in coastal sections. Inland there are few exposures and they comprise pebbly, well-rounded, medium-grained sands."@en .

The Member may also overlie the sands of the Corton Formation; where this occurs, the base is marked by the incoming of gravel."@en . "stable"@en . .
