Abstract
The Appalachian Orogen is divisible into the ancient North American miogeocline to the west, and some 18 suspected terranes to the east (Fig. 1) (1). A terrane is an internally homogeneous geologic province with features that contrast sharply with those of nearby provinces. The most extensive terranes along the orogen are, from west to east, the Piedmont, Dunnage, Gander, Ava-lon, and Meguma. Two other large terranes occur east of the Ava-lon in the southeast; however, these are buried beneath very thick sediments of the Atlantic Coastal Plain (Fig. 1) (1). In general, these terranes are believed to have accreted against ancient North America in a west to east progression through time. Earlier and more western dockings may have been by head-on ob-duction and/or subduction; later and more eastern ones perhaps by oblique convergence or major transcurrent movements during latest accretion (1).
