Résumé

The integration of 2D seismic interpretation, gravity modeling, and thermal maturity data reveals the superposition of four different deformation styles, developed over four deformation phases in the Chaleurs Bay area, Quebec, Canada. The first deformation phase, the Tremadocian- Arenigian Taconic Orogeny, is characterized by a southeast- directed hinterland dipping duplex mostly involving the Hadrynian-Lower Cambrian Maquereau Group. The second deformation phase, the Late Ordovician post- Taconic extension, is marked by the development of a ramp-flat listric extensional fault system which controlled the deposition of the Upper Ordovician Honorat and Matapédia Groups. During the third deformation phase, the Middle Devonian early stage of the Acadian Orogeny, thrusts faults inherited from the Taconic Orogeny are reactivated and normal faults inherited from the post-Taconic extensional phase are inverted. Strike-slip faulting along the Grand-Pabos and Garin River faults occurred during the fourth deformation phase, the Middle to Late Devonian late stage of the Acadian Orogeny.
