The Well Cuttings Collection consists of well cuttings from 7,376 oil and gas wells in Virginia. This collection is available for study by scientists, citizens, government agencies, and by industry. DGMR is developing an online web-based application for searching and viewing the information about these well cuttings.

The sinkhole locations shown on these maps have been digitized and are available as a draft ESRI shapefile. DGMR plans to complete a quality control analysis and modifications of the digital representation of these locations prior to release to the public.

The Mineral Resources of Virginia (MRV) Program oversees the inventory of specific mineral occurrences, prospects, mines, quarries, and other mining and processing sites of base and precious metals, industrial minerals, and energy resources in the Commonwealth of Virginia. The resulting information is formatted for inclusion in the MRV database. The goal of the MRV Program is to establish and maintain a digital database of statewide mineral and energy resources information to serve the following purposes: Preserve key information about mineral occurrences, mines, prospects, oil and gas extraction sites, and mining-related processing sites in a digital archive; Support public safety and environmental investigations;...

The Coal Quality Data Collection includes results of laboratory analysis for 375 coal samples collected as part of a cooperative sampling program between DGMR and the U.S. Geological Survey (USGS). The samples were collected by DGMR staff during the period from 1975 to 1988 from a six county area in the Southwest Virginia Coalfield. A total of 38 coal beds are represented in the sampling program. For each sample location there are laboratory results for Proximate and Ultimate analysis, ash-fusion temperatures, and major- and minor- element analyses.

The Aerial Photographs Collection consists of high- and low-altitude, black and white (B/W) and color (C) aerial photographs taken between 1936 and 2002. Flight coverage is mainly in Virginia, but there is also overlap into the adjoining states of Kentucky, Maryland, and West Virginia. Photo coverage is not complete for the entire state for any given flight year. A minor part of the collection (<5%) includes infrared photos. The photos are generally in paper format and suitable for use as stereo pairs. Many of the photos were taken during 1950-60 as part of the U.S. Geological Survey program to photo-revise the topographic map series. Photo-mosaic index maps are unavailable for many of the flight missions.

The collection consists of sample location information and laboratory geochemical characterization of Virginia's carbonate rocks. Laboratory analytical data includes major and minor constituents, and trace element analyses, reflectance and chlorine content analyses on a selected subset of the samples. This data is available for study by scientists, citizens, government agencies, and by industry. DGMR maintains this collection to support the wise use of Virginia's resources by providing quality geologic and mineral resource information. The collection consists of about 5,400 sample analyses currently stored in the Virginia Geologic Information Catalog.

The Historic Uranium Exploration Information Collection consists of scanned images of reports, maps, laboratory analyses, and other data that was collected by Marline Uranium Corporation during the period from 1979 to 1985. The documents pertain to the Coles Hill uranium deposit located in Pittsylvania County, Virginia. Most of this information has been scanned and is available in PDF format. There are approximately 1,500 digital files associated with this collection.
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....

The Borehole Database for Virginia provides information about boreholes drilled by Virginia Energy as part of on-going geologic mapping studies conducted in the Coastal Plain of Virginia. This collection is available for study and sampling by scientists, citizens, government agencies, and by industry. Virginia Energy maintains this collection to support the wise use of Virginia's resources by providing quality geologic and mineral resource information. The collection includes records for approximately 1,800 boreholes, with location information, lithologic log, and interpreted formation contacts. These boreholes were drilled for water wells, geologic research, geotechnical engineering studies, and environmental...

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 Clay Sample Collection consists of descriptions of physical and chemical characteristics of Virginia’s potential clay resources. Field sample descriptions include physical appearance, sample interval, and location information. Laboratory analyses included geotechnical tests for plasticity, workability, dry strength, pH, bloating, and firing. For some samples there may also be laboratory results for major, minor, and trace parameters. The collection includes 870 sample records published in DGMR Publications 36, 68, 76; Bulletins 2, 13, 20; and Mineral Resources Report 2, 5, 6, 8, 12, and 13. This collection provides statewide data on potential clay materials resources which could be used for ball clay, floor...

The geophysical data collection consists of geophysical data sets that are relevant to Virginia and include seismic lines, basemaps, processed seismic data, magnetic data, aeroradiometric surveys, gravity surveys, etc. This collection covers a variety of seismic studies completed by numerous companies and institutions. Seismic data is stored in the Natural Resources building as paper maps, magnetic tapes, film, and digital files. The geophysical data collection is accessible by appointment with DGMR staff.
