Ringgold Gap

Abstract

North end of Taylor Ridge, on south side of I-75, southeast of Chattanooga, Tennessee, 10 mi (16 km) southeast from junction of I-24 and I-75. Catoosa County, Georgia, Ringgold 7½-minute quadrangle. Accessible from I-75 or via frontage road eastward from the western of two Ringgold exits (Georgia 151, Fig. 1). The cut may be conveniently examined away from traffic on the first or second terrace.

“…This thick sedimentary sequence is primarily considered (Text- Figures 1 and 2; localities 4 and 5 of this paper) shallow marine, with facies ranging from turbiditic through tidal channel deposition (Adams et al, 1926;Bearce, 1973;Chowns, 1972aChowns, , b, 1989Chowns and Howard, 1972;Chowns and McKinney, 1980;Rindsberg and Chowns, 1986;Thomas and Bearce, 1971; Thomas and Neathery, 1980).…”

“…34 C 54'24" N, Long, 85°06'06" W). This section has been discussed by Butts and Gildersleeve (1948) Chowns (1989), Chowns and Howard (1972), and Rindsberg and Chowns (1986). Stratigraphic unit collected: Red Mountain Formation (measurement in maroon siltstone beds from base of second cut).…”

“…Most important, but usually absent, is an exact indication of the sampled level in the section. This is particularly acute in a exposure of great thickness (e.g., Text- Figure 2, locality 4; Ringgold Gap, is 284 m (930 ft.) thick; Rindsberg and Chowns, 1986). The location of the Red Mountain Formation samples yielding Beromia rexroadii gen. emend, et sp.…”
