Both basement and cover rocks are exposed in the Blue Ridge anticlinorium, a major tectonic element that extends for more than 300 km northeastward from near Lynchburg, Virginia to the vicinity of Carlisle, Pennsylvania (Figure 1). Proterozoic rocks in the core of the anticlinorium are stratigraphically overlain by lower Paleozoic rocks. On the northwest limb of the anticlinorium these strata include a basal Cambrian clastic sequence (the Chilhowee Group), a Cambrian through Middle Ordovician miogeoclinal sequence consisting of carbonates and mature clastics, and various shallow marine to terrestrial strata of Late Ordovician to Carboniferous age. Collectively they constitute the classic sequence of the Valley and Ridge province of the central Appalachians.
