Detailed cross-section logging and photo mosaics have been used to accurately depict the varying styles and relative timing of deformation directly beneath the Saltville Thrust, Giles County, Virginia. Four sections that are located along the regional strike in the footwall to the Saltville Thrust were chosen for comparison, because of their seemingly unique styles of deformation within a relatively small area. Each section is on the upright limb of a regional-scale, overturned syncline within the Moccasin and Martinsburg formations. Detailed logging has confirmed that, although each section appears structurally unique, the operative deformational mechanisms are surprisingly similar. All sections are characterized by extensive faulting and folding, and pervasive cleavage development. Folds range from gently plunging, upright, tight folds to asymmetric, northwest verging folds. Many of the folds exhibit structural thickening and thinning of their limbs caused by bedding plane slip that occasionally ramps through the stratigraphy.
