Description
The formation was named by E. R. Cumings to refer to the exposed rocks found near Staunton, Clay County. Later surveys resulted in the inclusion of the Perth Limestone Member into the Staunton Formation, having previously belonged to the Brazil Formation.
The Staunton Formation is made up of sandstone and shale (75 to 150 feet), and coalbeds (up to 8).[2]
