Abstract
The Appalachian Plateau fold belt is coincident with the boundaries of the Salina Salt, terminating on the northeast at the northern extension of the Lackawanna syncline in south-central New York and northeastern Pennsylvania, and on the southwest at the Burning Springs anticline in West Virginia.
Present information shows that in the New York-northern Pennsylvania area, Appalachian Plateau folds are decollements on the Salina Salt. The folds above the thickened salt bear no relation to folds or faults which may or may not be present beneath the salt.The decollement may have originated either by gravity sliding from the west or by thrusting from the east. There is evidence to support each mechanism. Deformation caused by thrusting from the east is the preferred interpretation.
