Dataset contains digital versions of physical core logs housed in Missouri Geological Survey archives. The logs are variable in detail, ranging from simple locations and formation tops to extensive stratigraphic descriptions and chemistry. A portion were done by MGS staff; others were donated by industry, academia, and government entities. The dataset includes logs for mines or undeveloped deposits with occurrences of or potential for critical minerals, along with logs in areas with permissive geology. The dataset comprises three tables: header and location information; formation/stratigraphic top, bottom and written description; and geochemical and assay data.
Boxes and maps of uranium exploration data were donated to the CGS several years ago referred to as the “Tallahassee Creek data.” This exploration data set focuses on the Hansen/Taylor, Picnic Tree, and High Park uranium deposits in the Tallahassee Creek mining area. These uranium deposits, a critical mineral as defined by Fortier and others (2018), occur in the Eocene Echo Park Alluvium and Oligocene Tallahassee Creek Conglomerate. Between 1957 and 1972, 95,400 tons of ore averaging 0.25% triuranium octoxide (U3O8) were mined in this area mostly from the Tallahassee Creek Conglomerate (Chenoweth, 1980). Exploration companies report Hansen/Taylor deposit resources of 29,730,000 tons grading at 0.063% U3O8 containing...
The Lynne Deposit is a Volcanogenic Massive Sulfide Deposit in Oneida County in northern Wisconsin containing zinc, lead, silver, and small amounts of gold and copper. In 1990 and 1991, the Noranda Company drilled 133 exploration boreholes, and the core from some of these holes was donated to WGNHS and the Natural Resource Research Institute (NRRI) in Duluth, MN. In 2021, the NRRI donated core from seven holes to WGNHS. These cores were photographed, and detailed logs were created by Dr. Robert Lodge and students from the University of Wisconsin Eau Claire. Original documentation from the Noranda Company including logs, assays, cross sections, reports, and a site map are available at Oneida County’s website: https://www.co.oneida.wi.us/archive/mining/category1da1.html?linkcatid=9...
Collection includes cores extracted over decades by mineral exploration firms as they completed their Maine work or otherwise released their data, covering both public and private lands that were the subject of mineral exploration. These records represent the best public collection of the major mineral exploration efforts of the 1960s-1980s. This collection of 595 scanned core records is accessible through a Google Earth application. Please contact the Maine Geological Survey to discuss access to the collection.

Compilation of rotary sonic drill cores with magnetic susceptibility measurements collected by Minnesota Geological Survey Quaternary geologists. The full dataset is available upon request and includes 1) magnetic susceptibility profiles for each rotary sonic core, 2) named unit averages and standard deviations for each county, and 3) named unit averages and standard deviations for all data.

This collection is comprised of all field samples collected by the U.S. Bureau of Land Management Non-fuel solid mineral branch and the former U.S. Bureau of Mines housed at the Alaska Geologic Materials Center in Anchorage, Alaska. This collection represents the entirety of the BLM Alaska rock collection, totaling 117476 samples consisting of many sample types from core, hand, pan concentrates, stream sediments, thin sections, pulp and other miscellaneous sample types
GIS files for the 1:150,000-scale Geologic Map of Gunnison County included in Colorado Geological Survey RS-37 Geology and Mineral Resources of Gunnison County, Colorado.

Dataset contains point data describing the results of 1-channel and 12-channel seismic refraction studies mapped at a scale of 1:24,000, from the Maine Geological Survey. The results include the depth to the water and depth to the bedrock. Links are also provided, when available, to the profile graphs for the seismic line.
The collection consist of 7 valves of the extinct Pliocene scallop species Chesapecten jeffersonius encrusted with bryozoan colonies

This collection contains sediment core samples collected during the 2015 India National Gas Hydrate Program Expedition 02 (NGHP-02), which was operated in the area of the Krishna-Godavari Basin along the Eastern Continental Margin of India. The samples are stored in cardboard boxes on one wood pallet.
WGNHS has approximately 240 cores donated to us by the Wisconsin Department of Transportation. The cores are from shallow holes drilled in the course of construction projects, mostly for bridges, culverts, and retaining walls. Photographs of the core are available through the WGNHS Data Viewer, and logs for approximately 70 of the cores are available on request.
Field notebooks of the New Jersey Geological Survey Geologists and non NJGWS Geologists including Paul Albrecht, Haig Kasabach, Joseph Miller, Jim Charlesworth, Richard Dalton, George Bonino, Ron Parker, Hugh Houghton.

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.

The Charles Sandberg Conodont Collection represents over 50 years of seminal research on the taxa (species and subspecies), zonation, biofacies, localities, and distribution of Devonian/Carboniferous-age conodonts in the U.S. and around the world. This collection is extensive, very-well documented and is particularly important for reconstructing the biostratigraphy and palaeogeography of the Paleozoic Era. The collection also includes books, notes, and other reference materials associated with Dr. Sandberg's research. Additionally, the collection is supported by a 4th Dimension database (in need of conversion and updating), that provides managed access to the collection and tabular content collected as part of Dr....

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...
GIS data collected from map plates within Colorado Geological Survey MS -17 Inventory of Nonmetallic Mining and Processing Operations in Colorado. The GIS dataset includes full metadata, the new shapefiles, and a layer file with symbology for ArcGIS. Also included is a 2022 Excel spreadsheet of all entries. The original report includes seventeen plates and text of locations of pits, quarries, and industrial minerals operations and processing plants of nonmetallic mining in Colorado. Covers: Vernal, Grand Junction, Moab, Cortez, Craig, Leadville, Montrose, Durango, Greeley, Denver, Pueblo, Trinidad, Sterling, Limon, Lamar, La Junta, Front Range Corridor and Southwest Pueblo.

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...
