Vanadium is used primarily in the production of steel alloys; as a catalyst for the chemical industry; in the making of ceramics, glasses, and pigments; and in vanadium redox-flow batteries (VRBs) for large-scale storage of electricity.

Analytical results and the evaluated source data files of a geospatial analysis for identifying areas in Alaska that may have potential for hosting mineral deposits of this type.

New major and trace element geochemical analyses of alkaline igneous rocks in this area. of historic gold mining in order to characterize the tellurium and other trace element constituents of predominantly unaltered rocks genetically associated with mineralization, to help understand the mechanism of enrichment in these deposits. 75 samples were analyzed by a variety of modern techniques and instruments.

Geochemical analyses of samples to understand which methods best delineate known mineral deposits in this area. Data are provided in CSV and shapefile formats.

Electron probe data collected for apatite, rutile, and titanite to fingerprint porphyry-style mineralization near the Taurus deposit in eastern Alaska. Data are provided in CSV format.

Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) analyses of apatite provide trace element concentrations that support indicator mineral studies in this deposit. Data are provided in CSV format.

Numerous porphyry copper-molybdenum-gold and epithermal deposits define a belt that extends from Eastern Alaska to western Yukon, Canada. An orientation study conducted near the Taurus porphyry deposit was designed to test methods that require minimal sam

This report presents geochemical analyses for 220 mostly altered and mineralized rock samples from the Red Dog Zn-Pb-Ag district in the western Brooks Range of northern Alaska.

Geochemical, x-ray diffraction mineralogical, and electron probe microanalysis (EPMA) data on rocks, soils, and sediments collected near porphyry copper deposits in this area. Data are provided in CSV format.

Geochemical data for stratigraphic rock sequences containing dominantly fine-grained clastic rocks with appreciable organic carbon (above 0.5 weight percent), usually known as 'black shale facies examples' but including all fine-grained clastic rocks such as argillite, mudstone, claystone, and their low-medium grade metamorphic equivalents. Data are provide in Microsoft Access and tab-delimited text formats.

Alaska is a major producer of base and precious metals and has a high potential for additional undiscovered mineral resources. However, discovery is hindered by Alaska’s vast size, remoteness, and rugged terrain. New methods are needed to overcome t

High resolution mineralogical mapping from hyperspectral core imaging data allows us to illustrate the spatial distribution of key mineralogical vectors in and around a deposit. This knowledge aids in rapid assessment of exploration models and the development of precise resource domains.

Elemental concentration data for more than 1700 archived stream-sediment samples collected in Alaska.

Hyperspectral analysis of rock samples using this equipment provide information on the composition and morphology of the minerals in the rock in microscopic detail. Data are provided as imagery in various formats.

Reflectance, mineral predominance, and white mica wavelength position data calculated from an airborne hyperspectral imaging survey of this area using a HyMap sensor in 2014. Data are provided in a format generated by the ENVI software product, CSV, and GeoTiff.

Demand for critical raw materials is expected to accelerate over the next few decades due to continued population growth and the shifting consumption patterns of the global economy. Sedimentary basins are important sources for critical raw materials and n

Analytical results for geochemical samples collected in 2007 from the Pebble deposit and surrounding environs

Chemical analysis of surface samples taken over a well known but concealed deposit to understand metal migration into the surface materials and to assess the power of surface sampling for detecting concealed deposits of this type.

Aeromagnetic data are used to better understand the geology and mineral resources near the Late Cretaceous Pebble porphyry Cu-Au-Mo deposit in southwestern Alaska. The reduced-to-pole (RTP) transformation of regional-scale aeromagnetic data shows that the

Uninterpreted geophysical measurements and geochemical and mineralogical analytical data from samples collected during the summer field seasons from 2007 to 2010. Data are available in a single Geographic Information System (GIS) database.

Describes resource management challenges and the providing of a scientific foundation for policy and decision making with respect to resource use, sustainability, environmental protection, and an adaptive resource management approach.

Explains the major questions and strategic actions to be carried out by the USGS to understand energy and mineral resources, their effects on the environment and on the economy and provide information to the public to support decision making.
