FGS Station 1/964 - Harveys Creek [Jackson Bluff Fm] (Pliocene of the United States)

Where: Leon County, Florida (30.4° N, 84.6° W: paleocoordinates 30.5° N, 83.9° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Jackson Bluff Formation (Alum Bluff Group), Late/Upper Pliocene (3.6 - 2.6 Ma)

• Cancellaria Zone of Choctawhatchee Formation, Alum Bluff Group. The Cancellaria zone is in the highest fossiliferous beds along Harveys Creel. The total thickness of this zone is 25-30 ft. Late Miocene age based on recent lithostratigraphy. Local section name = Harveys Creek, Basinal/regional section name = Leon. Placed in Jackson Bluff Fm (and hence Late Pliocene) by enterer.

• group of beds-level stratigraphic resolution

Environment/lithology: coastal; unlithified, fine-grained, coarse, shelly/skeletal, argillaceous sandstone

• No reported geologic or paleoenvironmental data. Probably shallow water siliciclastic depositional environment.
• The sediments comprising the Cancellaria Zone consist of a fine to coarse grained clayey sand containing many fossils. Lithification data not reported, but all figured specimens appear to be free of matrix so an unlithified classification is assigned.

Size class: macrofossils

Reposited in the USNM

• Specimens are lodged in USNM collections. Collected by Mansfield (1925)
