The New Jersey Zinc Company Historical Collection contains details of mining operations at the Austinville-Ivanhoe underground lead-zinc mines located in Wythe County in southwestern Virginia from 1902 to 1981. This site also operated under the name Bertha Mineral Company. The records pertain mainly to the historic Austinville-Ivanhoe underground lead-zinc mines located in Wythe County. The site produced zinc and lead from underground mines in the historic Austinville-Ivanhoe mineral district located in Wythe County. During this nearly 80-year span of continuous mine operations near Austinville, the company also conducted base metals exploration in other regions of Virginia, including the Timberville lead-zinc...

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.
Summary The documents in this collection, Open File Reports (OFR), represent information the Arkansas Geological Survey (AGS) has amassed from many past and present staff and other geoscientists friendly to the AGS. Friends who contributed include past and present federal, state, and local government personnel, academia, and private industry. The OFR collection consists of unpublished paper files which includes reports, correspondence, mineral and rock data, geochemical analyses and testing, county data, regional data, maps, charts, cross sections, stratigraphic data, paleontological data, and fossil fuels data. An Excel database was created to help searches by capturing the individual file title, abstract, data...
This collection consists of samples with age data and associated information for available radiometric dates for rocks and minerals in Alaska. The sample records and their associated publications were loaded into the Alaska Division of Geological and Geophysical Surveys division-wide database. A legacy Microsoft Access database exists that includes dates for all available U-Pb, K-Ar, 40Ar/39Ar, and Rb-Sr data for Alaska through 2007. Previous compilations by Wilson and others (1990) and U.S. Geological Survey (1999) provided the initial source of age data. Additional radiometric dates were compiled from both published and unpublished sources. This legacy project added essential basic supporting information that...

This collection is comprised of oil- and gas-related well cores and cuttings from wells drilled to either test for the presence of liquid or gas fossil fuels, examine subsurface stratigraphy and structures, or to produce liquid or gas fossil fuels. All well data in the Alaska Geologic Materials Center (GMC) database represents both exploration and production wells. Core has been donated by oil and gas exploration companies as well as state and federal agencies. This oil and gas related sample collection includes core, core chip, side wall core, cuttings, and unwashed cutting samples as well as oil and gas related surface and shot-hole samples.

This sample collection consists of a 1997 donation from the Shell Oil Company to the Alaska Geological Materials Center. It contains approximately 68,000 samples of following types: dart (short seafloor cores), seismic shothole, outcrop, and megafossils. 80% of the collection are outcrop samples. 5 percent of the collection has been inventoried with specific locations. Most of the collection is in good shape though many megafossil sample bags need to be replaced. The remainder of the collection will be inventoried in a future data preservation project

Dependable access to critical minerals information is vital to ensuring the continued domestic security and economic prosperity of the United States. At present, Alabama has known deposits, prospects, and occurrences of at least 21 of these commodities, including aluminum, arsenic, barium, beryllium, chromium, cobalt, fluorite, graphite, lithium, magnesium, manganese, platinum group metals (PGMs), rare earth elements (REEs), tantalum, tin, thorium, titanium, uranium, vanadium, zinc, and zirconium; but may have as many 31, including potential occurrences of gallium, germanium, hafnium, indium, lanthanum, nickel, niobium, rhenium, selenium, and yttrium. Although none of these commodities are currently being produced...

Minnesota Geological Survey, in cooperation with industry, sampled the State of Minnesota and adjacent regions for till geochemistry and indicator minerals at a 30-km spacing during summer 2004. Within target cells, each a quarter-degree latitude by a half-degree longitude, till from between about 1 and 2 m depth was sampled by filling a 15 liter plastic pail. At a few sites, vertical profiles were collected. In addition, three transects to the north were sampled, to help identify sediments derived by long-distance glacial transport, to obtain reference samples from the Thompson nickel belt, and also to extend sampling to the limit of Hudson Bay-derived carbonate-bearing sediments, to permit comparison to Minnesota...

All sediment samples from auger holes, outcrops, and cores are processed to determine texture. The 1-2 mm coarse sand fraction is packaged separately, and about half of these fractions are categorized lithologically by a glacial geologist. The data are recorded on paper data sheets and in a database.

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 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...
