Continuous bedrock core from about 50 sites across CT. Stored in 1100 boxes. This collection has been rescued three times since its formation in the late 1980's. Formerly administrative responsibility was shared between the University of Connecticut Dept. of Geology and Geophysics (now disbanded) and the Dept. of Environmental Protection, Geological and Natural History Survey. The State Survey now houses the collection and is the sole administrator.

This collection includes field notes, interpretive geologic field maps, field station location maps, and other project materials, many of which are unpublished and archived by the Alaska Division of Geological and Geophysical Surveys. These materials have not been reviewed for accuracy, consistency, or completeness. The collection may contain data and documents pertaining to all related fields of geology, including oil and gas, geologic engineering, minerals industry, scientific data, and agency archives.

This collection contains micropaleontologic age determinations on rock cuttings from 285 wells throughout New Mexico. There are 855 pages of information. This material has been donated or obtained as a result of survey research projects. Most data are fusulinid determinations on rocks of Upper Paleozoic age but there are some palynologic age determinations of other stratl age ranges as well. Located in the Subsurface Library.
This collection is comprised of legacy DGGS geologic maps that have been converted to the single-map USGS Geologic Map Schema (GeMS; formerly known as NCGMP09). Initial conversions will be conducted on maps in areas with critical mineral potential, benefiting DGGS and USGS critical mineral studies in Alaska. Future additions to this collection will include both converted geologic maps, and new geologic maps created using the GeMS schema.
Subset of rock cores and cuttings held by the West Virginia Geological and Economic Survey (WVGES) that have been inventoried and have had bar codes added to individual boxes. Bar codes indicate individual footage in each box.
This collection houses the results of laboratory analyses of different geological material. Analysis results may include: grain size, radiocarbon dates, clay mineralogy, pXRF, soil carbon and nitrogen, matrix carbonate, bulk density, and clast lithology data.

Hand specimens of rocks collected as a part of field work conducted primarily by present and former WGNHS staff members. Samples date from the early 20th century to the 1990s and were collected throughout the state. Many of the samples are described in the historical field notebook collection, and relationships between the samples and the field notebooks have been established and captured in identifiers. Locations for samples were taken from field notes, maps, and accession lists. There are approximately 5,700 hand samples in this collection.

This collection contains unpublished, working maps, and cross-sections from a wide range of projects. Some of the documents date back to over 50 years ago. Many of these documents are scanned.

This collection as a whole includes diamond drill core from hardrock/lode mineral prospects that have been donated to the Alaska Geologic Materials Center (GMC) by private entities or that have been recovered from properties during reclamation of historic mine and exploration sites by the U.S. Bureau of Land Management. The core is stored in waxed cardboard or plastic boxes. Mineralized portions, and in some cases the entire the core, has been split and sampled. Some core may have been quartered and sampled, or entirely consumed. The condition and completeness of the core varies widely. The individual records listed are comprised of diamond drill core from identified mineral prospects; it may include some coal prospects,...

In 2008, Virginia Department of Energy 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...
This collection represents the DGGS Alaska mineral resources and exploration database, with a focus on critical minerals. The Alaska Minerals Database (AMDB) provides access to information on all "significant" occurrences and properties in Alaska, including any known references to by-product critical minerals. This collection helps agencies and industry identify and prioritize regions and Alaska deposit models prospective for a variety of commodities, including critical minerals. The collection includes XXX records of Alaska mines, development and exploration projects, and significant mineral prospects.
