PBDB Collection

Vogtle Electric Generating Plant (Eocene of the United States)

Where: Burke County, Georgia (33.1° N, 81.8° W: paleocoordinates 33.7° N, 70.3° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: NP 16 nannofossil zone, Blue Bluff Formation, Lutetian (47.8 - 41.3 Ma)

• Hulbert et al (1998) state that the age is latest Lutetian or Bartonian, NP 16. Geisler & Beatty (2010) state that it it Lutetian.

• bed-level stratigraphic resolution

Environment/lithology: deep subtidal shelf; poorly lithified, concretionary, gray, argillaceous lime mudstone

• upper part of an 8 m bed that "was soft and poorly indurated" with "small concretions""relatively shallow but open water. A shelf environment is inferred...""Aragonitic mollusks and anthozoans are preserved either as external or internal molds, but calcitic shells appear unaltered"

• gray argillaceous calcilutite

Size class: macrofossils

Preservation: original calcite
