Petrologic and faunal study of a 72.5m continuous corehole drilled in southeastern North Carolina has provided an opportunity to study a relatively uninterrupted vertical sequence across the Cretaceous-Tertiary boundary. The following stratographic sequence occurs; upper middle Maastrichtian Peedee Formation, –65.8m to –51.8m below sea-level (BMSL), upper middle Maastrichtian Rocky Point Member of the Peedee Formation, –51.8m to –27.4m BMSL, and middle to upper (?) Eocene Castle Hayne Limestone, –27.4m to 15.2m BMSL (base of casing).
The Peedee Formation consists of moderately indurated, very fine to fine, sandy foraminiferal biomicrite and sandy biomicrite. Silt-size zoned dolomite rhombohedra form up to 30% …
