    The Connecticut Valley–Gaspé (CVG) trough represents a major, orogen‐scale Silurian–Devonian basin of the Northern Appalachians. From Gaspé Peninsula to southern New England, the CVG trough has experienced a contrasting metamorphic and structural evolution during the Acadian orogeny. Abstract. Deep-marine foreland basins may develop during continent-arc or continent-continent collision upon relatively thin lithosphere. Plate interactions that generate essentially compressive stresses to develop a thrust imbricate stack may result in lithospheric flexure and the initiation of a foredeep or foreland basin.

The migration pattern of the orogen and foreland basin suggests that during collision, a southeasterly plate that included the Acadian orogenic wedge and its Avalonian backstop overrode the Taconic-modified margin of North America.

The implied minimum plate-convergence rate is about 6 mm/yr. The Acadian orogeny is a long-lasting mountain building event which began in the Middle Devonian, reaching a climax in the early Late Devonian.

It was active for approximately 50 million years, beginning roughly around million years ago, with deformational, plutonic, and metamorphic events extending into the Early Mississippian. The Acadian orogeny is the third of the four orogenies that.

Migration of the Acadian Orogen and foreland basin across the Northern Appalachians of Maine and adjacent areas Professional Paper By: Dwight Culver Bradley, Robert D.

Tucker, Daniel R. Lux, Anita G. Harris, and D. Colin McGregor. The migration pattern of the orogen and foreland basin suggests that during collision, a southeasterly plate that included the Acadian erogenic wedge and its Avalonian backstop overrode the Taconic-modified margin of North America.

The implied minimum plate convergence rate is about 6 mm/yr. Foreland-basin clastic wedges associated with the Taconic, Acadian, and Alleghanian orogenies have long been known in the Appalachian orogen (Fig.

10; King, ; Chapter 4). As peri-Gondwanan terranes approached southern Laurentia, leading to the Taconic Orogeny, several thousand meters of orogenic flysch were deposited and then subsequently. The Acadian orogeny is mostly responsible for the deformation in the northern Appalachians between New York and Newfoundland.

The tectonic stresses brought on by the collision of the Avalonian tectonic plate with the convergent boundary of northeastern Laurentia began the formation of the early Appalachian orogeny. BibTeX @MISC{ical, author = {Dwight C.

Tollo, Mervin J. Bartholomew, James P. Hibbard, Paul M. Karabinos. The evidence for the Acadian orogeny is abundant and widespread in the northern Appalachians, recorded by the plutonism and the migration of the northern Appalachian deformation front toward the craton. The year marked the th anniversary of the beginning of the deportation of the Acadians from Nova Scotia and adjacent areas to points around the Atlantic rim.

A defining moment in the history of the Acadian people, the deportation also changed irrevocably the human geography of what is today Canada’s Maritime Provinces. Although De [ ].Foreland basins are a product of tectonic deformational loading, or crustal thickening along the orogen, a consequence of overthrusting and Acadian foreland basin is categorized as a retroarc foreland basin, which occurs on the overriding continental lithosphere, adjacent to a foreland fold-thrust belt behind a continental margin arc.

The initial result of loading is a bulge move.The Acadian orogeny occurred near the beginning of a major period of mountain building in earth's history lasting for million years.

Nearly every continent was affected. A t the same time, sea level was rising and the Kaskaskia Sea, entering from the Gulf of Mexico, spread north across North America, placing most of it under water.

Eventually it lapped onto the inland margins of the.
