The Devonian continental rocks outcropping between Campbellton, New Brunswick and Miguasha, Quebec are regrouped on the basis of new stratigraphic information and the ages now suggested are thought to be in accord with new data. An Early or early Middle Devonian age for the La Garde Formation is apparent and a strong unconformity is noted at the base of this unit. The Pirate Cove Formation (Middle Devonian) is subdivided into five lithological units. The Fleurant and Escuminac Formations, of Late Devonian age, are included in the newly proposed Miguasha Group. The tectonic implication of the lithologies and the structural relationships of these rocks is a pulsatory sequence of uplifts.
