Pg. 1. Hermitage formation. Even-bedded, alternating thin layers of argillaceous or siliceous blue limestone and gray or bluish shale in lower third, and heavier-bedded siliceous subangular limestone, more or less strongly phosphatic, in middle and upper parts. Thickness 40 to 70 feet. Unconformably overlies Carters limestone and underlies Bigby limestone. Age is Middle Ordovician (early Trenton).
[Named from occurrence at Hermitage Station, Davidson Co., west-central TN. Extends into southern KY.]

Pg. 81-107, measured sections. Hermitage formation of Nashville group. Basal formation in Nashville group (redefined). Includes Curdsville member (at base) and facies or members referred to as laminated argillaceous silty nodular limestone; DALMANELLA coquina; granular phosphatic; CTENODONTA; and blue clay-shale. Maximum thickness 180 feet. Underlies Bigby-Cannon formation; unconformably overlies Carters limestone of Stones River group. Hayes and Ulrich referred to section in vicinity of Hermitage Station but did not locate or reproduce the section. Bassler (1932, Tennessee Div. Geol. Bull., no. 38) stated location of section and gave thickness as 67 feet. In present study, several sections were measurede in section in bed of Stoner Creek and northward up hill located just west of bridge on Central Pike over this creek. This is probably locality were section was measured by Ulrich and Bassler.
Type area: near Hermitage Station on hill between Stoner Creek and Lebanon-Nashville and Central Pikes, Davidson Co., west-central TN.

Catheys (Catoosa Co.) and Cannon and Hermitage (Walker Co.) regarded as members of Nashville Formation of Chickamauga Group in this report, following the nomenclature of Carter and Chowns (1986: AL Geol. Soc. Guidebook, 23rd Ann. Field Trip) and Carter and Chowns (in press: Amer. Assoc. Pet. Geol., Studies in Geology). Hermitage overlies Carters Member of Stones River Formation in report area.

The Hermitage Formation of the Nashville Group in central Tennessee is divided into (ascending) the Curdsville Limestone Member, laminated argillaceous member, DALMANELLA coquina member, granular phosphatic member, CTENODONTA member, blue clay-shale member, and silty nodular limestone member. The Curdsville Limestone Member, which onlaps the Carters Limestone on the flanks of the Nashville dome, consists of thin- to medium-bedded, coarsely crystalline limestone. The Hermitage Formation is 70 to 180 feet thick. Overlies the Carters Limestone of the Stones River Group and underlies the Bigby-Cannon Limestone (as used by Wilson, 1949) of the Nashville Group. The Hermitage is of Middle Ordovician (Kirkfieldian) age.
