• calcaire a concretions siliceuses

•les depots recifaux ou subrecifaux debutent des le Lias inferieur; ils sont amorces par des constructions de buttes de boue carbonatee, souvent dolomitisee et construites a partir d'organismes autres que les Madreporaires (Algues, Spongiaires). (interpreted as the reefs and subreef deposits begin in the lower Lias; they begin with the construction of carbonate mud mounds, which are often dolomitized and are composed in part of organisms other than coral (algae, sponges))
