Summary:

Tobacco Road Sand, here named in Richmond Co., GA, consists of sand with minor chert and limestone. Unit is greenish-gray, and weathers red. Thickness is 8.5 m at the type locality and ranges from 3 to 8.5 m elsewhere. Described as medium- to coarse-grained, fossiliferous, coastal marine deposits. Includes Sandersville Limestone Member at base. Gradationally or disconformably overlies Irwinton Sand or Twiggs Clay; disconformably underlies Hawthorn(?) Formation or undivided Tertiary and Quaternary deposits. Unit was former unnamed upper sand member of Barnwell Formation. Age is late Eocene.

Summary:

Nomenclature follows Huddlestun and Hetrick (1978). Tobacco Road Sand is a maximum of 18 m thick. Underlies unnamed surface deposits and overlies Irwinton Sand Member of Barnwell Formation. Age is modified to late Eocene and Oligocene based on downdip fossils.

Summary:

Pg. 10-11, 14, 21, geol. map. Tobacco Road Sand, upper formation of Barnwell Group (see Huddlestun and Hetrick, 1978). Slightly to moderately burrowed in the coarser-grained beds, and heavily bioturbated in the finer, better-sorted beds. Cross-bedded ovoid-shaped gravel layer at base suggests a high-energy, shallow marine, probably shoreface depositional environment. Overlies Dry Branch Formation of Barnwell; underlies "Upland unit." Age is considered late Eocene; age undetermined from study area.
Type section stated to be about 1 mi east of junction of Tobacco Road and U.S. Route 1 near Augusta, GA [a few mi west of quadrangle bdry., approx. Lat. 33 deg. 23 min. 36 sec. N., Long. 82 deg. 06 min. 00 sec. W.].
