Palaeolandforms and morphotectonic evolution around the Baie de Chaleurs (eastern Canada)
International audience A morphological study of the Baie des Chaleurs area, between northern New Brunswick and the Gaspé Peninsula (eastern Canada), leads to the identification of several types of palaeolandforms in the landscapes of the northeastern Appalachians. One of them, the exhumed sub-Carbon...
