Calcareous nannofossil assemblage data from the upper Floridan Aquifer in the Pineora, Cockspur Island, and Palm Dunes cores, GA and SC Calcareous nannofossil assemblage data for the Pineora, Cockspur Island, and Palm Dunes cores. Categories: Data; Tags: Hilton Head, Marine Geology, Savannah, USGS Science Data Catalog (SDC), paleontology Cenozoic Calcareous Nannofossil Occurrences from Mid-Atlantic Coastal Plain Cores, Wells, and Outcrops 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.

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...

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...

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... Tags: Accomack, Alexandria, Anne Arundel, Baltimore, Brightseat Formation, All tags...

Extensive taxonomic analysis of the macrofauna over the past 100 years includes documentation of swimming reptiles, fish, marine invertebrates, and plant material. However, documentation of the palynomorph and calcareous microfossil component at the type locality has never been done. This data set provides analysis of calcareous microfossils (benthic and planktic foraminifera, calcareous nannofossils, and ostracods) and palynomorphs (pollen, spores, algal remains, and...
