Summary:

Lobelville formation named as top formation of Brownsport group. Lower 9 to 31 ft, called Bryozoan zone, consists of red and purple shales overlain by soft blue to white shales. Upper 0 to 45 ft, called Coral zone, usually consists of thin-bedded clayey limestone and whitish shales so prolific in fossils that their disintegration upon hillsides leaves the ground covered with specimens. Overlies Bob formation and underlies Decatur limestone. Age is Silurian (Niagaran).

Summary:

Author proposes that terms Beech River, Bob, and Lobelville be abandoned as there does not appear to be any valid basis for subdividing Brownsport into three members or formations.

Summary:

Pg. 264-266, figs. 2, 78. Lobelville formation of Brownsport group. Included in Brownsport group. Conformably overlies Bob limestone; where Bob limestone is not typically developed, Lobelville and Beech River, locally in contact, cannot be separated lithologically; unconformably underlies Decatur limestone, a Devonian formation, or Chattanooga shale. In deeper part of structural saddle between Nashville dome and southeastern extension of Ozark dome, thickness averages 35 feet, locally being 40 or 50 feet. Distribution restricted to parts of Hardin, Wayne, Decatur, Perry, and Hickman Counties. [Age is Middle Silurian.]

Summary:

Lobelville Member of Brownsport Formation occurs in du Pont Geohydrological Survey well near Waverly, Humphreys Co., central TN. Specimen of conodont PSEUDOONEOTODUS BICORNIS? at 607.4 to 608.4 ft in underlying Bob Limestone Member could indicate an early Ludlovian or older Wenlockian age at that level. Overall age of Brownsport is Wenlockian to Pridolian.
