摘要
Lithology, sedimentology and palaeoenvironments allow a lithostratigraphic subdivision of the Red beds into five formations. A marine episode identified near the top of the first formation is Early Bathonian in age. An erosional unconformity overlies this marine level just below the Lower Cretaceous deposits. It could be related to a large sedimentary gap between the Lower Bathonian and the Lower Cretaceous series. (C) Academie des sciences / Elsevier, Paris.).
