Summary:

Named the Elway for settlement of Elway, near Lebanon, Russell Co., VA. Consists of dove gray to dark bluish gray fine-grained argillaceous limestones containing chert which weathers into characteristic blocks. Average thickness is 35 to 40 feet. Unit overlies the Blackford formation and underlies the Five Oaks limestone. The Elway is of Middle Ordovician age.

Summary:

The Elway Limestone is shown on stratigraphic column to be of Early Ordovician age. Consists of olive to dark gray, fine-grained, commonly thin-bedded limestone, with some gray calcilutite, shaly fine-grained limestone, and abundant gray blocky chert. Unit overlies the Blackford Formation and underlies the Lonesome Pine Formation.
