Geologic Names and Usage: A Guide to Stratigraphic Nomenclature

American Geosciences Institute

About This Course

Stratigraphic nomenclature is the system of proper names given to specific stratigraphic units, which provides a universal language essential for all scientific publications. Consistent and effective communication in the geosciences requires systematic use of stratigraphic nomenclature. The importance of consistent stratigraphic nomenclature as a means of effective geologic communication has been recognized since the USGS established the Geologic Names Committee (GNC) in 1899 to evaluate and address issues of nomenclature. This course is designed to provide a review of geologic names usage and stratigraphic principles that serve as a foundation for professionals and students to improve geoscience communication among all industries.
