Title: The Hockingport and Waynesburg Sandstones (Pennsylvanian and Permian) of the Dunkard Group: ABSTRACT

Author(s): Wayne Martin, Bernard Henniger

Article Type: Meeting abstract


The Waynesburg Sandstone, lower member of the Waynesburg Formation, Dunkard Group (Pennsylvanian and Permian), has been considered to be a more or less continuous deposit extending entirely across the Dunkard basin. The true Waynesburg Sandstone is restricted in areal extent to southwestern Pennsylvania and northern West Virginia. A similar sandstone deposit, which exists in portions of Washington, Athens and Meigs Counties, Ohio, and adjacent West Virginia, has been considered to be a part of the Waynesburg Sandstone. In the opinion of the writers, these sandstones are not correlative. The sandstone of southeastern Ohio is herein termed the Hockingport Sandstone for the village of that name in Athens County.

The Hockingport Sandstone is a subgraywacke. It contains much pebble and granule conglomerate and averages 65 per cent quartz. The Waynesburg Sandstone is transitional between a subgraywacke and a protoquartzite, is locally conglomeratic, and averages 76 per cent quartz.

Both sandstone bodies are elongate, channel-fill, belt-type deposits of fluvial origin. The Hockingport Sandstone is a north-south oriented deposit up to 90 feet thick, blanketing an area of 225 square miles. The longer axis of the Waynesburg Sandstone is oriented N 20° E, the maximum thickness is 75 feet, and the preserved deposit blankets an area of 880 square miles. The grand mean of dip directions of cross-stratification readings of the Hockingport Sandstone is N 19° W and of the Waynesburg Sandstone, N 10° E.
