Limestone referred by Veatch and Stephenson (1911) to McBean formation and by Cooke and Shearer (1918: USGS Prof. Paper 120-C) to upper part of Barnwell is herein named Sandersville limestone member of Barnwell formation. Thickness probably not more than 40 ft. Thickness at type locality is 19 ft. Age is late Eocene.

Sandersville limestone member is believed to be equivalent in part to the Irwinton sand member (new), but it may represent in part a still younger bed of Jackson age.

Sandersville used at formation rank on Georgia State map. Age shown as Eocene.

Sandersville is restricted to a relatively small area in central Washington Co., GA. Unit correlates with Ocmulgee Formation (new name) but is referred to Tobacco Road Sand because sandy sediments of formation occupy same stratigraphic position where member is absent. Unit grades laterally in all directions into Tobacco Road Sand. Overlies Irwinton Sand Member of Dry Branch Formation. Age is late Eocene.
