Paleozoic carbonate rocks flooring Page Valley (within Page County) are overthrust by Precambrian to Cambrian elastic rocks of the Blue Ridge to the east of the study area. King (1950) recognized that the Cambrian carbonate sequence of Page Valley, near Stanley, Virginia, is broken by a large transverse fault which he named the Stanley fault. King (1950) interpreted the Stanley fault as a high-angle reverse fault with oblique-slip displacement. However, detailed mapping and structural data collected in this study indicate the Stanley fault is a low angle thrust fault which cuts all pre-Alleghanian and Early Alleghanian structures.

Two previously unrecognized thrust faults, the Newport-Grove Hill and Honeyville faults, have been identified in this study as a folded, foreland propagating imbricate thrust system within the North Mountain thrust sheet. After detailed geologic mapping, it has also been determined that the northern extension of the Newport-Grove Hill fault is the Leaksville -Hamburg fault. These faults are Alleghanian in age and predate the Stanley fault. Geologic mapping revealed the occurrence of four distinguishable, mappable units within the Beekmantown Formation. Three balanced cross-sections were constructed to illustrate the relationships between the thrust faults detected in this study and the regional geologic framework.
