Ordovician arc collision and foredeep evolution of the Gaspe Peninsula, Quebec: the Taconic Orogeny in Canada and its bearing on the Grampian Orogeny in Scotland
The Middle to Upper Ordovician Deslandes, Cloridorme and Garin Formations in the eastern Gaspe Peninsula, Quebec, are some of the most extensively exposed foredeep successions along the northern Appalachian portion of the Taconic-Caledonian orogen. Their depositional and biostratigraphic frameworks...
