The Core Research Center (CRC) was established in 1974 by the USGS to preserve valuable samples of the Earth’s subsurface for use by scientists and educators representing government, industry, and academia. The CRC collections include full-diameter rock cores, slabbed cores (cut in half longitudinally), well cuttings, thin sections, and associated analytical data. A majority of the material was donated to the CRC by private industrial companies, although some cores and cuttings were collected by the USGS and other government agencies. Rock cores were collected from roughly 9,500 drilled borehole locations representing approximately 610,000 meters (2 million feet) of subsurface strata in 35 states. Many of the boreholes...

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

The U.S. National Ice Core Laboratory (NICL) is a National Science Foundation (NSF) facility for storing, curating, and studying meteoric ice cores recovered from the glaciated regions of the world; mostly from Antarctica and Greenland. The NICL is funded by the NSF Division of Polar Programs and operated by the USGS; and the NICL’s science operations are managed by the University of New Hampshire. NICL provides scientists with the capability to conduct examinations and measurements on ice cores, and it preserves the integrity of these ice cores in a long-term repository for future investigations. The NICL was established in 1993 and is located at the Denver Federal Center, in Denver, Colorado. The NICL’s primary...

Collections of physical samples and data managed and preserved by the U.S. Geological Survey (USGS). The separate collections are managed by different projects and Mission Areas of the USGS. The collections are distributed across the United States, in various USGS offices. Preservation of some of these collections may be supported by the National Geological and Geophysical Data Preservation Program. USGS strives to publicly expose its materials, data, and other research to further scientific inquiry. Points of contact for individual collections may be contacted to request access to materials and data.
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.

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...

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).

Since its inception in 1879, the USGS has collected and preserved geoscience data and sample collections, which include millions of paleobiological specimens stored in USGS facilities and at the Smithsonian Institution National Museum of Natural History (NMNH) in Washington, D.C. As one of the largest paleontological collections in the world, the USGS paleontology collection is invaluable, as many specimens may no longer be collected due to high field collection costs or inaccessibility to sampling sites, which have been restricted, urbanized, or modified via landscape processes. The USGS Denver Paleontology Collection includes ~1.2 million specimens stored in 1000 Smithsonian museum cases. The primary collections...
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....

Library collection of 34 out-of-print Biennial Reports of the Commissioners of the State Geological and Natural History Survey to the Governor and State Legislature of Connecticut. These historic reports chronicle the legacy and evolution of the State Geological and Natural History Survey of Connecticut from its inception in 1903 until it became an entity of the state environmental agency in 1971. This collection include 682 pages of text, 18 figures, 9 plates, and 2 map sheets. These reports are valuable to science historians, academic scholars, geoscience professionals, and public policy experts. A related Connecticut Survey Library collection contains associated historic correspondence. Although most of the...

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.

Since 2002, the Woods Hole Coastal and Marine Science Center’s Samples Repository has been supporting research by providing secure storage for geological, biological, and geochemical samples; maintaining organization and an active inventory of these sample collections; as well as by providing access to these collections for study and reuse. This collections inventory has been compiled, organized, and released online to provide researchers and the general public with a means to discover and request scientific sample material preserved and maintained by the Woods Hole Coastal and Marine Science Center Samples Repository. Updates will be made to the inventory as the collections grow, and version history is available...
