A most important ingredient in the evolution of the orogen was the Alleghany orogeny, The Alleghany orogeny in the central and southern Appalachians was a Metamorphism and magmatism were significant events during the earlier Physiography. Formation of an orogen is accomplished in part the tectonic processes of subduction (where a continent rides forcefully over an oceanic plate (noncollisional orogens)) or convergence of two or more continents (collisional orogens). Orogeny usually The Dog Bay Liberty Line and its significance for Silurian tectonics of the northern Appalachian orogen 1 2 Douglas N. Reusch, a Cees R. Van Staal b a Department of Geology, University of Maine at Farmington, 173 High Street, Farmington, ME 04938, USA. The fragments related to the Grenville orogen are commonly identified as internal and external massifs based on their relative position to the metamorphic core of the Appalachian orogen (Hatcher, 1984) and many have now been described in some detail (e.g., papers in Bartholomew, 1984, Tollo et al., 2004c). The external massifs are along the eastern Holyrood Horst, and further define the nature of their boundary. The age of the volcanic host to the largest zone of pyrophyllite diaspore alteration, established in earlier stages of this investigation, is now precisely defined at 584 1 Ma.

The Pennsylvania salient also marks a narrowing of the Appalachian orogen, suggesting a change from thin-skinned to thick-skinned deformation, to be tested with future EarthScope data.
