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. Outer-shelf and deep-water deposits crop out in western Newfoundland. The shelf break and upper slope are nowhere exposed, but their nature has been determined from numerous clasts in sediment gravity flows redeposited on the lower slope and now stacked in allochthonous thrust complexes.
The relatively thin part of the platform (approximately...

Controls on Carbonate Platforms and Basin Development
Controls on Carbonate Platform and Basin Development - This volume is derived from the SEPM Research Symposium of the same name that was formulated for the Los Angeles meetings of AAPG and SEPM in 1987. The volume covers many subjects relative to geology of carbonate platforms and adjoining slopes and basins. A preliminary section, based on principles of deposition and computer modeling studies, is followed by a group of papers devoted to examples of carbonate platforms on passive cratonal margins resulting from rifting. Some of the examples are from major platform systems around North America and the Mesozoic of Tethys. Other studies are of local and individual platform-basin systems. Examples of both ramps and rimmed platforms are included. The case histories presented span the whole of geologic time from early in the Proterozoic to the Holocene.
