Abstract

The Cormeilles-en-Parisis hill shows one of the best geologic sections of the Paris region. The 80 meter high working face of the quarry exposes the complete section of the "Ludian" [the youngest beds of the Eocene] with its alternations of the marl and gypsum. Above is the sequence of supra-gypseous marls of the [lower oligocene] Sannosian stage, overlain by a very complex series of alternation brackish water and lacustrine layers, from blue marls to Brie limestone, up through the white Pantin marls, brown marls containing the pelecypod genus Cyrena and green marls. These strata overlain by the [Middle Oligocene] Stampian beds represented by the Fontainebleau sands and Ostrea-bearing marls.
