AB Several levels of conglomerate cropping out in the Peña de Francia syncline were previously includedin the Ordovician basal unit. However, a Lower Cambrian conglomerate can be identified inside, even inthe areas where the basal Ordovician unconformity is not exposed. The Cambrian conglomerate witnessthe filling of deep water channels by mass flow; whereas the Basal Ordovician conglomerate indicates thestarting of the Ordovician transgression in a coastal environment under tides and waves regime. Sedimentaryand lithological data from the conglomerates and geochemical data from interlayered slates support thisinterpretation
