Summary:
Though Siple (1967) referred to the beds overlying the Warley Hill as the McBean Formation, authors are using term Santee because of priority. They informally refer to the light-colored, calcareous part of the section as the "McBean beds," the gray and green, laminated, calcareous part as the "Blue Bluff beds," and the siliciclastic part as the "Tims Branch beds." The Santee is late middle Eocene based on dinoflagellates, calcareous nannofossils, and other taxa.
