- Abstract
The Newfoundland Fracture Zone, the southwest Grand Banks transform, and the Cobequid–Chedabucto fault zone form a linked strike-slip fault system from the Atlantic Ocean to southeastern Canada. This paper suggests that several large-scale geological features in southeastern Canada are the result of a small amount of strike-slip motion on the system during the mid Cretaceous and Oligocene. Regional extension features developed in the releasing bend in the Laurentian sub-basin during the mid Cretaceous, but the same area experienced Oligocene compression. This tectonic model accounts for the distribution of mid-Cretaceous volcanism, fault-bounded basins, and regional unconformities, as well as mid to late Cretaceous subsidence of the Scotian basin and Oligocene uplift of the eastern Scotian Shelf.
