Abstract
The eastern Blue Ridge structurally shows two major fracture sets dheonghant the rock bodies of the Basement Complex, the Lynchburg Group, Catoctin Formation, and Candler Formations. These fracture sets which strike Set 1 at 310° and 330° and Set 2 at 85° and 95° most closely correspond with fractures found in the Valley and Ridge of Virginia and West Virginia. These fractures most likely formed during the Alleganian Orogeny 320-280 million years ago. Set 2 is comparably older than Set 1 having formed at the peak of the orogenic event under compressional stresses. Set 1 formed later as a result of hydraulic faulting when the set was buried under the folds created in the orogeny. This orogeny accounts for majority of the brittle deformation seen in this fracture study of the eastern Blue Ridge.
