Alum Bluff Group
The Alum Bluff Group is a geologic group in the states of Georgia, Florida, and Alabama. It preserves fossils dating back to the Neogene period. Age Period: Paleogene to Neogene Epoch: Late Oligocene to Early Miocene Faunal stage: Chattian through Hemphillian ~23.03–5.33 mya, calculates to a period of Location The Alum Bluff Group replaces the Hawthorn Group west of the Apalachicola River with occurrences in Bay, Calhoun, Holmes, Jackson, Liberty, Okaloosa, Walton, and Washington counties. It is younger than the Torreya Formation to the east based on superpositioning. The Alum Bluff Group outcrops beneath a thin overburden in the western panhandle from river valleys in Okloosa County eastward to western Jackson County. Lithology The group is composed of clays, sands and shell beds. These vary from fossil bearing sandy clays to sands, clays, and carbonate beds absent of fossil content with glauconite and phosphate mica which is common. The coloration is from crea ...
