In this data release, Cenozoic calcareous nannofossil occurrence charts are provided as Microsoft Excel spreadsheets for 57 cores, wells, or outcrops from the Mid-Atlantic Coastal Plain (Virginia, Maryland, Delaware, and New Jersey) and one core from offshore New Jersey. Samples have been assigned a USGS sample number and are organized by depth below (cores and wells) or height above (outcrops) the land surface. Based on their known stratigraphic position, lithology, and specific calcareous nannofossil species content, each sample, where possible, was assigned to a geologic formation, age, and standard Martini (1971) calcareous nannofossil biostratigraphic zone. Six additional reference files are provided: (1) introductory...

The Cabin Branch and Cabin Creek (Cappy Avenue) outcrops are located along two small creeks in Prince George’s County, Maryland. The Cabin Branch outcrop contains exposures of silty sands of the Upper Cretaceous Severn Formation, and both outcrops contain Paleocene silty quartz and glauconitic sands of the Danian Brightseat Formation and highly fossiliferous glauconitic quartz sands of the Selandian Aquia Formation. Data from these two locations were generated in order to designate a Principal Reference Section for the Danian age Brightseat Formation. The Cabin Branch outcrop consists of disjunct exposures along an approximately 0.4-mile section of the creek. At the nearby Cabin Creek (Cappy Avenue) outcrop a more...
