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...

In this data release, Cenozoic calcareous nannofossil occurrence charts are provided as Microsoft Excel spreadsheets for 17 cores from the South Atlantic Coastal Plain (North Carolina, South Carolina, and Georgia) Samples have been assigned a USGS sample number and are organized by depth below 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. Five additional reference files are provided: (1) location information for each core, well, or outcrop, (2) a list of calcareous nannofossil species found...

The goal of the Atlantic Subsurface Stratigraphic Initiative (ASSI) is to create isopach and structural contour maps for all Coastal Plain formations within the Salisbury Embayment of Maryland and Virginia. Detailed information regarding thicknesses and extent of formations across state boundaries can then be utilized for more accurate documentation of the subaerial extent of aquifers across states. In support of this goal, lower Paleogene sediment elevation and thickness information from approximately 600+ data points from wells, cores, outcrops, and geologic maps were obtained from published and unpublished resources. Analyses started with production of a structure contour map of the unconformable contact of the...
