Bulletins are detailed scientific studies that include comprehensive and interpretive reports of significant interest and importance. Bulletins feature in-depth analysis of new data and have undergone internal and external peer review. 

Bulletins, with links to digital downloads, can be found on our Bulletins page.

Information Circulars fall into one of two categories:

1. Presentation of scientific data on a variety of topics that are not as in-depth as Bulletins, or
2. Publications intended for the general public, written in plain language on geologic topics related to North Carolina.

Information Circulars undergo internal NCGS review and often demonstrate how geology addresses public interest issues and can inform public policy and management decisions.

Information Circulars, including links to digital downloads, can be found on our Information Circulars webpage.

Open-file Reports are a collection of reports and/or maps representing preliminary research findings. They are not considered to be formal literature and may be superseded by updates or final products. Open-file reports are of the best available information for geological mapping in some areas and are internally reviewed for completeness and conformity to NCGS mapping standards.

You can browse these reports and maps, with links to digital downloads, on our Open-file Reports webpage.

You can view these historical reports and maps, including links to digital downloads, on the Open-file Reports and Maps page.

Special publications are a diverse series covering topics like structural geology, energy and minerals, and paleontology. These publications may be in cooperation with other agencies and often report findings from research conducted by non-survey scientists. These publications are subject to internal and external review.

You can browse the Special Publications, including some links to digital downloads, on our Special Publications webpage.

In comparison to Open-file Report maps, these maps have undergone additional internal and external review and refinement. They typically include detailed information relevant to the mapped area such as minerals resource summaries, locations of mines, quarries, and geochemical and age date sample locations. These maps are considered part of the formal geological literature and are usually published as final products.

Browse the maps on our Geologic Map Series webpage.

Last published in 1982, this map series presented the results of regional mapping across the state and was later compiled into the 1985 Geologic Map of North Carolina.

You can view the list of maps on our Regional Geologic Map Series webpage.

NCGS Volumes are a discontinued publication series last published in 1923. The Volumes publication was a limited series consisting of five volumes. Three of these Volumes are comprehensive reports on geologic topics. 

You can view the Volumes on the Volumes webpage. If you have questions about the NCGS Volumes series, please contact Michael Medina at michael.medina@deq.nc.gov.

Publications on the Field Trips Guidebook webpage were prepared for professional meetings regarding the geology of North Carolina. 

You can browse the Guidebooks with digital downloads on the Field Trip Guidebooks webpage.
