Abstract
Widespread Lower Ordovician sandstones (Armorican Quartzite facies) represent the initial passive margin sedimentation that occurred over a huge area of southwestern Europe during the late Floian. Their deposition ended during the Dapingian to early Darriwilian. Precursors of the Armorican Quartzite were deposited behind the border of a rift system, leading to the formation of conglomerate fans associated with the fault planes of tilted blocks generated during rifting of the Cadomian basement. ?Tremadocian deposits, coeval with volcanic events, are also recorded across this extensional basin. There is a scarcity of sedimentological studies and other elements aiding both correlation and a more accurate reconstruction of the basin architecture.
