Summary:

Named the Fido sandstone for Fido, Scott Co., southwestern VA. Consists of 50 feet of coarse, friable, brown to reddish sandstone. Overlies limestone equivalent in age to Gasper limestone and underlies Cove Creek limestone. Unit is probably correlative to Hardinsburg sandstone of KY. Known to extend from a point 5 miles west-southwest of Gate City to road between Lindell and Holston River in Abingdon quad. and probably extends nearly entire length of Mississippian trough southeast of Clinch Mountain. The Fido is of Mississippian age.

The Fido Sandstone is mapped with the overlying Cove Creek Formation on the geologic map of Virginia. Consists of calcareous, reddish-brown to dark-brown, fine- to coarse-grained, thick-bedded, cross-bedded and ripple-marked, fossiliferous sandstone with one or more beds of argillaceous limestone. Thickness ranges from 35 to 75 feet. Overlies the Greenbrier Limestone.
