The Valley and Ridge and Cumberland Plateau structures are treated as areas deformed by thin-skinned tectonics generated during the late Paleozoic, as is the Blue Ridge thrust sheet. The Blue Ridge anticlinorium, Murphy syncline, Chauga belt, mobilized Inner Piedmont, Kings Mountain belt...

... in the Blue Ridge, Chauga belt and Inner Piedmont, related to Taconic (450–480 Ma) metamorphism. Several later thrusts in the Blue Ridge and the Gold Hill–Silver Hill fault in the Piedmont have been dated as Devonian. Syn- to post-metamorphic faults in the eastern Piedmont are Hercynian. These were developed...

Early D 1 -D 2 structures are truncated by the Toccoa Falls-Shorts Mill fault, suggesting emplacement of the allochthon subsequent to their formation. Later D 4 -D 5 structures...
