| Stratigraphy comments: No lithostratigraphic details or stratigraphic relationships provided in text. From Siple (1957) "The Duplin in South Carolina is considered to be equivalent to the upper Yorktown of Virginia and the Cancellaria biofacies within the Choctawhatchee stage of Florida." AGE: Late Pliocene. Campbell (1974) suggested an age of zone N-20, or about 3.0-3.5 Ma for the type section of the Duplin Fm at Natural Well, late Pliocene age. | |||||
