Paleozoic reactivation structures in the Appalachian-Ouachita-Marathon foreland: Far-field deformation across Pangea

The Proterozoic Grenville orogeny (~ 1300–980 Ma) reactivated the Archean-hosted Kapuskasing suture in Laurentia which then propagated west and south initiating the Keweenaw rift (1141–1085 Ma) which closed by thrust shortening at 1060 Ma. Late Proterozoic-Paleozoic sediments were then deformed in association with the amalgamation of Pangea in the late Paleozoic causing ~ 30 km of thrust shortening along this 4000 km paired (inverted) fault...
