Auteur : Office québécois de la langue française,Notes :
The rifted continental margin off Nova Scotia is an example of the continental margins of eastern Canada.
The most common models for the evolution of rifted continental margins divide their history into an early phase of continental rifting, perhaps involving uplift, horizontal extension, erosion, and volcanism, and a later stage of continental drift, during which sea floor forms between the two continental blocks and the margins and subside and are blanketed with sediments.Terme :
