The literature dealing with the history of the Vicksburg group at Vicksburg, Mississippi, is reviewed and summarized. A discussion of the stratigraphy of the exposed strata is given. The foraminiferal content is considered in detail, and a check list is presented.
The Forest Hill sand is proved to be of Vicksburg (Oligocene) age because it overlies the Red Bluff clay where the two interwedge. The Salt Mountain limestone, until recently placed at the top of the Vicksburg group, contains Discocyclina, and is Lower Eocene; according to Blanpied, it lies between the Nanafalia formation and the Tuscahoma sand of the Wilcox group. The Chickasawhay marl and the Bucatunna clay are accepted as members of the Byram marl. The chert beds of southeastern Alabama, Georgia, South Carolina, and Florida, formerly classed as Glendon, are named the Flint River formation and are tentatively correlated with the Chickasawhay member of the Byram marl. The Catahoula sandstone appears to be older than the Tampa limestone.
