The northwestern margin of the northern Appalachian Orogen and adjacent craton is a Lower Paleozoic, low-latitude carbonate platform that originally lay along the northern margin of the Iapetus Ocean. Parts of the platform interior are now exposed in Quebec, but much lies beneath the Gulf of St. Lawrence. The geology of the Appalachians dates back to more than million years ago. A look at rocks exposed in today's Appalachian Mountains reveals elongate belts of folded and thrust faulted marine sedimentary rocks, volcanic rocks and slivers of ancient ocean floor – strong evidence that these rocks were deformed during plate birth of the Appalachian ranges marks . early paleozoic margin of laurentia – quebec city area 5 recognized in many parts of North America, truncating Early to Middle Ordovician strata .

The Paleozoic era began and ended with supercontinents and in between were the rise of mountains along the continental margins, and flooding and draining of shallow seas between the mountain ranges, in the interior of the continents.

An extensional continental margin developed on the western margin of Laurentia from Mexico to Yukon during the breakup of Rodinia about – Ma, commencing with a series of Precambrian rift basins, followed by the development of a wedge of Paleozoic continental margin (“miogeoclinal”) sediments up to 6 km thick. Shallow-water carbonate. The two platforms developed at the margin of the Quebec Reentrant and St. Lawrence Promontory in the Gaspé Belt of the northern Appalachian Orogen. It is not clear whether they were parts of a single continuous platform stretching along the northern margin of the Gaspé Belt or two separate platforms occupying distinct tectonic by: Ophiolite obduction in the Quebec Appalachians, Canada – Timing and evidence for syntectonic Erosion Article in Canadian Journal of Earth Sciences 49(1) January with 82 Reads. The Early Paleozoic continental margin of Laurentia preserved in western Newfoundland was built on the St. Lawrence Promontory (Thomas, , Thomas, ; Allen et al., , Allen et al., ; Chapter 1). Autochthonous and transported rocks are preserved. The best known of the allochthons is the Humber Arm Allochthon (Williams, ).Author: Denis Lavoie.
