Tectonic development of this East Coast of Canada

The East Coast of Canada is usually split into three areas: the Nova Scotian margin when you look at the south, the Newfoundland margin at the heart and eastern, therefore the Labrador margin into the north (Figure 1). These margins formed in the past 200 million years because the supercontinent of Pangea rifted apart, first as North America separated from Africa after which because it separated from European countries and Greenland (Figure 2). These episodes of rifting thinned and heated the continental crust and lithosphere, which in turn subsided to create a complex pair of marginal basins. Considerable amounts of sediment have actually since accumulated in these basins and created sources and traps for hydrocarbon deposits. Continue reading
