Regional geology of Eastern Canada offshore
The continental shelf of E. Canada extends from the Gulf of Maine to the head of Baffin Bay in the Northwest Territories, a distance of 3,500 miles (5,600 km). On the mainland the oldest outcrops are Proterozoic, present on the Labrador coast and Baffin Is. The Atlantic Provinces occupy the N. part of the Appalachian System, a belt of folded and unfolded middle and lower Paleozoic sedimentary rocks subjected to the Taconic and Acadian orogenies. Late Paleozoic faulting and folding along the Funday geosyncline resulted in deposition of Mississippian continental and marine sediments in intermontane troughs, overlain by flat-lying late Pennsylvanian and Permain clastic sediments. Triassic rocks are retricted to a rift zone extending from the Bay of Funday to Chedabucto Bay. On the continental shelf and slope, the total rock section overlying a granitic or metamorphic basement, as calculated from seismic refraction, magnetics, and estimates from wells, reaches a maximum of more than 20,000 ft.
