| Devonian to Permian successions in the Appalachians of Atlantic Canada record intense deformation in zones related to transform faults active during the assembly of Pangea.;On the south shore of the Minas Basin, Nova Scotia, Late Paleozoic deformation affects the Mississippian Horton and Windsor Groups, lacustrine clastics and evaporites respectively. Structures exposed in cliffs and on wave-cut platforms include reverse faults and tight folds with axial-planar cleavage. Locally, overprinting has led to the development of downward-facing folds. Faults and folds are associated in outcrop-scale flower structures exposed in both cliff and wave-cut-platform view. Low angle thrust faults and oblique strike-slip faults played a role in emplacing Horton Bluff Formation strata over younger strata of the Windsor Group. Thrusting and strike-slip motion were followed by diapirism of Windsor evaporites. This deformation was associated with transpressional motion along the boundary between the Meguma and Avalon terranes of the Appalachians. |
