In 1962 Harry Hess's History of Ocean Basins gave a mechanism and a measure of credibility to the ancient hypothesis of continental drift. The new model has been successful in explaining Mesozoic and Cenozoic tectonics; therefore, it is remarkable that today there exists no general agreement on the number, age, and location of older Appalachian sutures. This volume contributes to understanding these sutures. Topics include: the nature of metavolcanic Carolina-Avalon terrane and its problematic western boundary in the Piedmont of central Georgia; the Cambrian(?) emplacement of Carolinian rocks against Laurentia in southern Virginia; and reactivation of the southern Virginia suture as a major zone of crustal weakness that moved during every subsequent tectonic event. Two papers argue against a suture in the Blue Ridge and suggest that the Laurentian plate boundary is the central Piedmont suture. A regional paper interprets the "Taconic"-Carolinian suture and the Laurentian margin through the central Appalachians and offshore continental margin.
