The Huntersville Chert Beds (Oriskany) are a geologic formation in the Appalachian region of the United States. They are composed primarily of chert, a hard, siliceous rock that is often used in surfacing roads. The Huntersville Chert Beds are found on the farm of Howard Barlow at Huntersville, West Virginia. They were used in surfacing State route 42 between Marlinton and Green Bank.
The Huntersville Chert Beds were deposited during the Middle Devonian Period, about 385 million years ago. They are part of the Onesquethaw Group, which also includes the Needmore Shale and the Bobs Ridge Sandstone. The Huntersville Chert Beds are about 15 to 100 feet thick. They are composed of a variety of chert, including gray, black, and yellow chert. The chert is often brecciated, meaning that it is broken into pieces and cemented together with silica.
The Huntersville Chert Beds are a valuable resource for road surfacing. They are durable and resistant to weathering. They are also relatively easy to quarry and transport. The Huntersville Chert Beds have been used in surfacing roads in West Virginia, Virginia, and Pennsylvania.
