Abstract
We reconsider the origin of the Purbeckian deposits (Uppermost Jurassic-Low ermost Cretaceous) of the Boulonnais. Made up of an erosional conglomerate overlain by wood fragments and clays containing continental and marine foss ils, they are attributed to a tsunami triggered by either an earthquake or the impact of a bolide in the palaeo-parents Sea.
