Argiles d'Octeville
The Argiles d'Octeville (meaning Octeville Clay) is a geological formation in Normandy, France. It dates back to the Kimmeridgian stage of the Late Jurassic.[1] It is equivalent to the Kimmeridge Clay in England[2] and predominantly consists of claystone, with some limestone.[3] It is well exposed in cliff section at Cap de la Hève
