Summary:
Named Lincolnshire limestone member of the Cliffield formation for a branch tributary of the Clinch River called Lincolnshire in Tazewell Co., VA. In Tazewell Co., the Chazyan and Black River groups of Butts (1940) are subdivided into 29 zones. The Lincolnshire limestone member of the Cliffield formation (zones 1-9) is proposed for zone 5, which consists of brownish-gray to black medium-grained irregularly bedded limestone averaging 60 feet thick (thickness at type locality is 102 feet). The Lincolnshire limestone member overlies the Five Oaks limestone member and underlies the Ward Cove limestone member, both of the Cliffield formation. The Lincolnshire is of Middle Ordovician age.

The Lincolnshire is raised to formation rank as the Lincolnshire limestone of the Cliffield group in the valley between Brushy and Walker Mountains. The Lincolnshire is the Leonir of Butts in belts southwest of Clinch Mountain but not the same as the Lenoir identified by Butts in some areas north of Clinch Mountain.

Summary:
Named the Eidson member of the Lincolnshire formation for Eidson, Hawkins Co., northeastern TN. Member is thin part of Lincolnshire that underlies the Hogskin shale. Consists of dark limestone containing black chert. Unit is present in Clinch, Hogskin, and Beaver Valleys. The Eidson is of Middle Ordovician age. Also named the Hogskin member of the Lincolnshire formation in Grainger Co., northeastern TN. Derivation of name not stated but name is credited to B.N. Cooper. Consists of yellow-weathering shale and cobbly limestone, both of "Ottosee type" and usually confused with that formation. Member overlies Eidson member of the Lincolnshire and underlies the Ward Cove or Rockdell formations. The Hogskin is of Middle Ordovician age.
