This extensive volume is a chronicle of the many current ideas on the Appalachian-Caledonian Orogen. The volume is organized based on the symmetry that was recognized in the Newfoundland Appalachians over thirty years ago by Dr. Harold Williams of Memorial University of Newfoundland. This two-sided symmetry is manifested in three elements: the Laurentian margin (platform), the Iapetan Oceanic realm (mobile belt) and the Gondwanan-related terranes (platform). The geological evolution of these elements forms the focus of the first three sections of this volume. The concluding section brings all of these elements together in considering the timing and nature of Laurentian-Gondwanan interactions.
