This collection is comprised of digital, slide and print photographs taken during engineering geology, energy and minerals resource related field projects from 1970-2020. These photos document field sites, geologic features, landscapes and landforms from the various areas of Alaska. There are collections specific to each of the Division's sections that document the effort needed to complete the culling and documentation of exisiting photos. As of 2020, DGGS has cataloged 19,724 photos, with 12,813 available to the public. Only those photos with location information are available within the National Digital Catalog

This collection contains test-hole cores through surficial sediments and shallow bedrock drilled by the Nebraska Geological Survey (Conservation and Survey Division), the Nebraska Department of Roads, the U.S. Army Corps of Engineers, and other organizations, including bedrock cores drilled by petroleum and mineral concerns. A portion of the cores in this collection originated from oil producing areas and areas with potential petroleum development within the Panhandle region of western Nebraska. These cores were drilled by oil companies between 1950-1969 and were later donated to the Nebraska Geological Survey (Conservation and Survey Division). With the assistance of the National Geological and Geophysical...

The Silica Collection consists of descriptions for 51 outcrop samples collected as part of an evaluation of potential high-silica resources in the western region of Virginia. Sampling was conducted in conjunction with reconnaissance field mapping to determine the extent of high-silica deposits. The record for each sample consists of a physical description, location information, sieve analysis, and chemical test data. The results of laboratory analyses are included in several published reports including DGMR Publications 32, 67 and Mineral Resources Report 11.
Geotechnical report collected for Seismic Hazard Zonation. The reports include borehole data (lithology, stratigraphy, ground water, sample type) and test data (blow count, grain size, shear strength).

In 2008, DGMR received by donation from the University of Virginia (UVA) a large collection of rock, mineral, and fossil specimens that was at risk of imminent disposal or dispersal due to the lack of adequate storage facilities. The collection includes many valuable and irreplaceable geologic specimens collected in Virginia by UVA students, faculty, and geoscientists from the early Virginia Geological Survey. Parts of the collection were at one time displayed in the Lewis Brooks Hall of Natural Science, which opened in 1877. Following the closure of the UVA Department of Geology in the 1960s, the collection was moved to various warehouse storage areas, where it was largely forgotten and inadequately preserved....
This collection includes 4,525 rock thin sections archived by the DMME Virginia Division of Geology and Mineral Resources. The thin sections represent a wide range of rock types in Virginia and are available for petrographic studies. Many, but not all of these thin sections are associated with rock specimens inventoried in the Rock Repository, identified by the tag "R-#####". Other thin sections represent rock specimens from earlier studies for which documentation may exist, yet the original rock sample may not be available. The location coordinates for the thin sections are approximate, given by the 7.5-minute quadrangle centroid. Work continues on this collection to better document missing information.

The Well Sample Library presently contains (1) approximately 10,000,000 feet of rock cuttings from 2,500 oil and gas test holes and water wells drilled in Arkansas; (2) 2,500 feet of core from 50 oil and gas tests mainly in south Arkansas; (3) 300,000 feet of core from 1,500 mineral exploration tests in the Ozark and Ouachita Mountains of Arkansas.
