“…Plusieurs auteurs ont décrit cet épisode plus au sud (De Boer et Clifford 1988;Lucas et al 1988). Ainsi, Manning et De Boer (1989) ont signalé, en NouvelleAngleterre, l'existence d'une phase compressive nord-sud associée à un faible hydrothermalisme de basse température déposant du quartz, des carbonates et de la barytine.…”

Groupe de recherche en géologie de terrain appliquée (GEOTERAP), Département des sciences de la Terre, Université du Québec à Montréal, C.P. 8888, succursale A, Montréal (Québec), Canada H3C 3P8Reçu le 25 juin 1991 Révision acceptée le 16 october 1991 L'évolution tectonique de la plate-forme appalachienne reste mal connue. Cependant, la région de Montréal montre la présence de grands accidents cassants dont certains recoupent les intrusions du Crétacé. La reconstitution des différents états de contraintes enregistrés par la plate-forme a été entreprise par une analyse des failles cassantes et des dykes, puis par le calcul par inversion des tenseurs des contraintes correspondants. Cette tectonique est polyphasée et permet de reconstituer l'histoire de la plate-forme carbonatée et flyschoïde depuis le Paléozoïque inférieur. On peut distinguer cinq épisodes tectoniques correspondant à des évènements géodynamiques majeurs du nord-est de l'Amérique du Nord : (i) les évènements distensifs précoces nord-sud; (ii) la compression appalachienne ouest-nord-ouest-est-sud-est; (iii) la compression nordnord-est -sud-sud-ouest fini-appalachienne; (iv) la distension nord-sud au Crétacé; (v) la compression dans le cadran nordouest -sud-est du Cénozoïque à l'actuel.The tectonic evolution of the Appalachian platform is still not well understood. The Montréal area, however, shows evidence of major fracturing events, some of which cut the Cretaceous intrusions. The history of the different stress events recorded in the platform was studied by the analysis of brittle faults and dykes, followed by the calculation, by way inversion of tensors, of the corresponding stresses. The tectonics represented is polyphased and its analysis allows a historical reconstitution of the carbonate and flyschoid platform since the Lower Paleozoic. Five tectonic stages are recognized, corresponding to the major geodynamic events characteristics of northeast North America: ( i ) early north-south distensional events; (ii) Appalachian compression in a west-northwest -east-southeast direction; (iii) terminal Appalachian compression oriented north-northeast-south-southwest; (iv) Cretaceous north-south distension; (v) a Cenozoic to Recent compression in a northwest -southeast direction.

“…We make this assumption for several reasons. First, left-lateral strike-slip on the NE-striking basin-bounding faults is kinematically compatible with the north-south shortening that affected the Newark Basin after rifting (Lomando & Engelder 1984;Lucas et al 1988). Second, many transverse folds are present near right steps (or bends) in the basin-bounding fault system (e.g.…”

We use seismic, field, core, borehole and vitrinite-reflectance data to constrain the development of the Newark Rift Basin, one of the largest and most thoroughly studied basins of the eastern North American rift system that formed during the break-up of Pangaea. These data provide critical information about the geometry of the preserved synrift section and the magnitude of post-rift erosion. We incorporate this information into a new structural restoration of the basin. Our work shows that the Newark Basin was initially narrow (,25 km) and markedly asymmetric; synrift strata show significant thickening towards the basin-bounding faults. Subsequently, the basin became wider (perhaps .100 km wide), deeper (up to 10 km) and less asymmetric; synrift strata exhibit subtle thickening towards the basin-bounding fault system. Several intrabasin faults dissected the Newark Basin after synrift deposition, and the basin fill was tilted (c. 108NW) and folded. Erosion (up to 6 km) accompanied the intrabasin faulting, NW tilting and folding, significantly reducing the basin size. Our work suggests that the eastern North American rift system is characterized by a very broad zone of upper-crustal extension in which a few, wide, deep, longlived, fault-bounded basins (like the Newark Basin) accommodated much of the extension.

“…DeBoer and Clifton [1988] also used smallscale faults to infer a NE-SW shortening direction for the Hartford basin. In the Newark basin, Lomando and Engelder [1984] inferred a N-S shortening direction based on calcite twins, whereas Lucas et al [1988] inferred a NNE-SSW shortening direction based on the geometry of the Jacksonwald syncline and its axial planar cleavage.…”

“…The most notable structures are: (1) broad NE-trending anticlines developed in the hanging walls of gently dipping, NE-striking border faults of the Fundy subbasin of the Fundy rift basin (Figures 7b, 8a); (2) tight ENE-to E-trending synclines and anticlines formed in proximity to the steeply dipping ENE-to E-striking border faults of the Minas subbasin of the Fundy rift basin ( Figures 7b, 8c); (3) generally NE-striking basementinvolved reverse faults and associated folds in the Richmond basin [Shaler and Woodworth, 1898;Venkatakrishnan and Lutz, 1988] (Figures 9a, b); (4) generally NEtrending inversion folds developed above NE-striking intrabasinal faults of the Taylorsville basin [LeTourneau, 1999] (Figure 9c); and (5) WNW-striking axial planar cleavage in some WNW-trending folds in the Newark basin [e.g., Lucas et al, 1988].…”
