A mineral resource assessment was performed by the U.S. Geological Survey (USGS) to assess the potential of undiscovered skarn-hosted tungsten resources in the Northern Rocky Mountain region of eastern Idaho and western Montana. This region has seen moderate tungsten trioxide (WO3) production in the past from a variety of mineralization styles including skarn, vein and replacement, and wolframite-quartz veins. The geology of the area is dominated by large plutons of Cretaceous to Tertiary age, emplaced into a belt of sedimentary rock ranging from Mesoproterozoic to Permian age, and affected by tectonism related to the Sevier and later Laramide orogenies. Known tungsten (W) skarn mineral sites are associated with...

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.

This digital geospatial compilation gathered paleoflow indicators from current-formed sedimentary structures throughout the Paleozoic Ozark uplift, Arkoma foreland basin, and Ouachita fold-thrust-belt of eastern Oklahoma and western Arkansas from existing publications. This dataset consists of unidirectional and bidirectional paleocurrents observed from a variety of bedform types represented by approximately 9,958 individual measurements and 665 calculated means (one .csv file) plotted as points (one .shp file) with subordinate Ordovician-Silurian and primarily Mississippian-Pennsylvanian ages.

This digital geologic map compilation presents new polygon(i.e., geologic map unit contacts), line (i.e., fault, foldaxis, and structure contour), and point (i.e., structuralattitude, contact elevations) vector data for the Jasper 7 1/2'quadrangle in northern Arkansas. The map database, which is at1:24,000-scale resolution, provides geologic coverage of anarea of current hydrogeologic, tectonic, and stratigraphicinterest. The Jasper quadrangle is located in northern Newtonand southern Boone Counties about 20 km south of the town ofHarrison. The map area is underlain by sedimentary rocks ofOrdovician, Mississippian, and Pennsylvanian age that weremildly deformed by a series of normal and strike-slip faults andfolds....

The database for the Preliminary Geologic Map of the Cherry Hill Quadrangle, Dinwiddie, Sussex, and Greensville Counties, Virginia geographically straddles the Coastal Plain and Piedmont Provinces along the Tidewater Fall Line. Rocks of the eastern Piedmont Roanoke Rapids terrane crop out in the western part of the quadrangle and consist of greenschist- to amphibolite-facies Neoproterozoic felsic to intermediate metavolcanic rocks, some of which contain flattened quartz phenocrysts and are locally isoclinally folded; greenstone that is locally primary layered; and intrusive metadiorite and metagabbro, much of which has been altered to amphibolite. Most of these rocks are strongly foliated and jointed. Greenschist-facies...

Hand specimens of rocks collected as a part of field work conducted primarily by present and former WGNHS staff members. Entries include rock hand samples related to WGNHS research projects with adequate geographic location information. These are available in the National Digital Catalog as of September 14, 2010. Documentation supporting other individual items in this data collection is currently being developed. Most of the hand samples are tied to field notebooks. Accession lists for the hand samples are available, but electronic versions of these notebooks are not currently available. Plans to integrate these into the existing master database of WGNHS data is under development. There are approximately 4,800 hand...

The 1:100,000-scale geologic map database of the South Boston 30' × 60' quadrangle, Virginia and North Carolina, provides geologic information for the Piedmont along the I-85 and U.S. Route 58 corridors and in the Roanoke River watershed, which includes the John H. Kerr Reservoir and Lake Gaston. The Raleigh terrane (located on the eastern side of the map) contains Neoproterozoic to early Paleozoic(?) polydeformed, amphibolite-facies gneisses and schists. The Carolina slate belt of the Carolina terrane (located in the central part of the map) contains Neoproterozoic metavolcanic and metasedimentary rocks at greenschist facies. Although locally complicated, the slate-belt structure mapped across the South Boston...

The Ouachita Mountains record the late Paleozoic Laurentia-Gondwana orogenic event along southern Paleo-North America during Pangea supercontinent formation. This data release contains a digital compilation of geomorphic-structural information from the Ouachita Mountains of southeastern Oklahoma and southwestern Arkansas as previously published by Arbenz (2008). The geodatabase, presented herein, contains feature classes that include contact, fault, fold, and cross section lines with map unit polygons characterized by predominantly siliciclastic material with primarily Paleozoic depositional ages. Spatial data are also disseminated as shapefiles, accompanied by applicable non-spatial tables detailing the data sources,...

This set of data files are the appendices for paper titled Transgressive-regressive cycles in the metalliferous, oil shale-bearing Heath Formation (Upper Mississippian), central Montana. The dataset consists of 8 appendices, including a histogram of solid bitumen and vitrinite Ro values, gas chromatograms, isotopic data, organic and inorganic geochemical analyses, and x-ray diffraction mineralogy data.
The Mineral Development Atlas (MDA) was a joint project by the United State Geological Survey (USGS), the United States Bureau of Mines (USBM), and the state surveys of Wisconsin, Illinois, and Iowa, and was launched in 1945 to gather information about mining and exploration in the lead-zinc district. The Atlas consists of section maps at 1:2400 scale showing exploration and mining activity in the lead-zinc district of the Upper Mississippi Valley. When the USGS offices in Platteville, WI closed, the Atlas was distributed to the states. The Wisconsin portion covers primarily Grant, Iowa, and Lafayette Counties, and WGNHS is currently working towards making the Wisconsin portion of the Atlas publicly available online....
