A Structural and Stratigraphic Excursion Through the Shenandoah Valley, Virginia
Orndorff RC and Epstein JB. 1994. A Structural and Stratigraphic Excursion Through the Shenandoah Valley, Virginia. U.S. Geological Survey (USGS) Open-File Report. 94-0573. USGS. Reston, VA
This field trip will examine many different formations at five locations (fig. 3). A variety of different rock types, including limestone, dolostone, shale, and graywacke, and structures, such as folds and faults, that reveal the geologic history of the Shenandoah Valley will be examined. Interpretations of the paleoenvironments and sedimentary processes prevalent during the Cambrian and Ordovician Periods will be presented at the first three stops. The last two stops will be along the North Mountain fault zone where folds and faults produced during the Alleghanian orogeny will be examined.
