Tectonic setting of Middle Devonian to Lower Carboniferous rocks in the Magdalen Basin

Abstract: Seismic reflection data in the Gulf of St. Lawrence were used to construct an isopach map of the Horton Group (Middle Devonian-Early Carboniferous) in the Magdalen Basin. The map shows that the Horton Group was deposited in basins that developed parallel to the offshore extension of structural trends in New Brunswick and the Gaspe Peninsula. Horton Group strata were deposited in narrow linear fault bounded basins, presently up to 8 km deep, and in broad sag basins up to 3 km deep. The sag basins may thin latte… Show more

“…2). La tectonique d'extension responsable de la formation du bassin des Maritimes et de ses sous-bassins est interprétée par certains auteurs comme le produit d'un 'rift avorté' lié à une compensation post-orogénique (Belt, 1968;Ruitenberg et al, 1973;Howie et Barss, 1975;Poole, 1976;Ruitenberg et McCutcheon 1982;Fyffe and Barr, 1986;McCutcheon et Robinson, 1987;Durling et Marillier, 1993), et par d'autres comme directement liée à une tectonique de cisaillement concentrée sur la géofracture de Minas (faille de Cobequid-Chedabucto) en Nouvelle-Ecosse (Ramsbottom, 1973;McMaster et al, 1980;Fralick et Schenk, 1981;Bradley, 1982;Keppie, 1982;Gibling et al, 1987;Ryan et al, 1988;Pe-Piper étal, 1989;Reed et al, 1993;Murphy et al, 1995;Jutras et Prichonnet, soumis-b: Chapitre 4 de cette thèse).…”

“…The western Maritimes Basin covers an area of more than 200 000 square kilometres and has a sedimentary fill ranging from mid-Devonian to Early Permian in age. Total thickness of the basin fill exceeds 12 km in the deepest central portions of the basin, as determined from seismic reflection data (Durling and Marillier 1993).…”
