Tectonic Evolution of the Southern Continental Margin of North America from a Paleozoic Perspective

  • James Helwig

Abstract

The objective of this paper is to discuss tectonic hypotheses for the Paleozoic evolution of the southern continental margin of North America building on the geological synthesis of P. B. King (this volume) to which the reader is directed for many references. At the outset, it must be acknowledged that our present grasp of Paleozoic paleogeography and tectonics is generally insufficient to permit unambiguous tectonic interpretation, plate or otherwise, of any Paleozoic mountain system. This is especially true for the southern Appalachian, Ouachita, and Huastecan systems which often are poorly exposed. It is nevertheless worthwhile to review major aspects of paleogeographic and tectonic history, however poorly known, in order to formulate simple models and actualistic plate-tectonic analogues that can be of value in understanding the geologic history of the region.
