Figure 34. Map showing contoured frequency of severely thrust faulted and folded (disturbed) zones observed in the field, per 7.5-minute quadrangle in relation to inferred lateral ramps in the central Appalachians. Contour interval is 5 disturbed zones. Hachures indicate closed area of fewer disturbed zones. Note peak frequency of 40 disturbed zones centered over the Roanoke lateral ramp. Single dashed line in southwestern Virginia marks major lineament parallel to ramps; there is not enough information to define both sides of the suspected ramp.
