Integration of 2-D high-resolution shallow seismic reflection and refraction, gravity, 2-D electrical resistivity, Ground Penetrating Radar, and borehole data were used to image the shallow subsurface expression of the Camden fault. The preferred model for the fault geometry suggests at least 28 m apparent offset of the Upper Cretaceous unconformity across a high-angle, northwest dipping, 21 m wide, reverse fault zone. The fault is interpreted to separate the Neoproterozoic-Early Paleozoic basement (Richtex Formation of Carolina terrane) on the northwestern side from the Modoc shear zone (MSZ) on the southeast side (sheared rocks of low-grade Richtex Formation and high-grade Mylonitic orthogneiss, Dreher Shoals terrane). The Camden fault is interpreted to be the brittle fault flanking the Alleghanian MSZ. The latest movement on the fault is constrained to be either late Cretaceous in age by offsets in the base of the Middendorf Formation, or younger, mid-Miocene by disturbances to the Upland Unit.
