Summary:

Named the Holston marble for the Holston River in TN. Marble beds in the same stratigraphic position as the lower part of the Chickamauga formation are called Holston marble on account of its distinctive appearance and economic importance. Color of the Holston varies from red, brown, gray and pink, but is mostly dark bluish gray and variegated reddish brown or chocolate. Thickness is 600 to 650 feet at Clinch Mountain, and thins in all directions. Unit is probably a lentil in the Chickamauga. The Holston is of Middle Ordovician age.

Summary:

Geographically extended the Holston marble into GA. Occurs only in a narrow belt just east of State Highway 71 to within 6 miles north of Dalton. Thickness is 50 to 100 feet. Unit overlies the Lenoir limestone and underlies the Ottosee (Sevier) shale.

Summary:

Revised the Holston to the Holston Limestone of the Chickamauga Group in eastern TN. Consists of gray, pink, and red, fine- to coarse-grained, thick-bedded, fossiliferous calcarenite with some interbeds of nodular gray limestone. Thickness is up to 525 feet. Unit overlies the Lenoir Limestone of the Chickamauga Group and underlies the Chapman Ridge (Tellico) Sandstone of the Chickamauga Group. The Holston is of Middle Ordovician age.
