From June to September 2017, the United States Geological Survey (USGS) collected a total of 116 surficial sediment and bedrock samples from abandoned mine wastepiles, ephemeral channels below wastepiles, nearby outcrops, and background areas representative of the undisturbed lithology on the western slope of the northern half of the Oquirrh Mountain Range, approximately 20 miles southwest of Salt Lake City, Utah. The sample locations can be spatially clustered into four groups: the Bates Canyon group in the foothills below Bates Canyon; the Middle Canyon group in Middle Canyon; the Ridgeline group within the Bingham Mining District located at or near the Tooele-Salt Lake County border on the Oquirrh Mountain ridge;...

Re-analyses of sample pulps and bulk rejects from historic USBM rock and heavy-mineral-concentrate samples were conducted by the Alaska Division of Geological & Geophysical Surveys (DGGS) as part of the State of Alaska's Strategic and Critical Minerals Assessment project, which is designed to evaluate Alaska's potential for these resources. The objective of this resource assessment is to expand the state's geochemical database by obtaining and publishing modern, quantitative geochemical analyses for historic USBM samples, where available. Highlights of this re-analysis project include heavy mineral concentrates with up 7,220 ppm Sn, 5,870 ppm Cr, and 17,000 ppm Mn.

The U.S. Geological Survey (USGS) has undertaken a mineral resources assessment for tungsten for a portion of the Great Basin in parts of western Nevada and east-central California. This data release provides the Great Basin Tungsten Database: the geospatial and geologic data, and results of chemical analyses for 46,955 samples collected in the assessment area, extracted from the USGS National Geochemical Database. These rock records were collected as part of various programs and projects at the USGS and analyzed from 1963 to 2015. The database represents rock records, each comprising one best value chemical determination for each analyzed chemical species, that include skarns, carbonate lithologies (for example,...

This data release provides multi-element data for drill core samples from the Mesoproterozoic Nonesuch Formation and Copper Harbor Conglomerate at the Copperwood copper deposit, Michigan, USA. Copper was determined by assay, and sulfur by inductively coupled plasma-optical emission spectrometry (ICP-OES) after aqua regia digestion for most samples. Multi-element whole rock analyses were determined for selected samples. The Copperwood copper deposit is a sediment-hosted stratiform copper deposit in the Presque Isle Syncline of the Upper Peninsula of Michigan. The deposit has a 2018 mineral resource estimate of 42.2 million metric tons (Mt) of measured plus indicated mineral resources in the Lower Copper Bearing Sequence...

Geologists from the Alaska Division of Geological & Geophysical Surveys (DGGS) Mineral Resources Section conducted four weeks of helicopter-supported mapping and fieldwork from June 26 through July 24, 2013. The Styx River project in the Lime Hills C-1 Quadrangle was part of the State-funded Airborne Geophysical/Geological Mineral Inventory (AGGMI) program as part of the State's Strategic Minerals Assessment Project, an initiative designed to evaluate Alaska's potential for rare-earth elements, PGEs, and other similarly supply-challenged resources. The Styx River project area has active and ongoing mineral exploration for deposit types including porphyry copper/molybdenum/gold, reduced intrusion-related gold, and...

In 2012, the State of Alaska established its Strategic and Critical Minerals (SCM) Assessment project, a State-funded Capital Improvement Project (CIP), to evaluate Alaska's statewide potential for SCM resources. The project is being implemented by the Alaska Division of Geological & Geophysical Surveys (DGGS), and involves obtaining new airborne-geophysical, geological, and geochemical data. For decades, the Ray Mountains area of west-central Alaska has been explored for its potential mineral resources. To further assess the rare-earth-element (REE) potential of the State-selected and top-filed lands in the Ray Mountains area, mineral-resource geologists at DGGS carried out a helicopter-supported geological and...

Mineral-resources personnel from the Alaska Division of Geological & Geophysical Surveys (DGGS) carried out a helicopter-supported geological and geochemical resource assessment project in the Beaver, Bettles, Livengood, and Tanana quadrangles from June 23 through August 5, 2012. The objectives of DGGS's resource assessment are to improve the trace-element geochemical coverage of selected watersheds; to obtain modern, quantitative geochemical analyses; to understand the petrogenesis of the granites; and to better document established mineral occurrences. Stream-sediment, pan-concentrate, and rock sampling were conducted as part of the State's Rare Earth Elements and Strategic Minerals Assessment project, which is...

The mission of the USGS National Minerals Information Center (formerly the Minerals Information Team) is to collect, analyze, and disseminate information on the domestic and international supply of and demand for minerals and mineral materials essential to the U.S. economy and national security. About 90 mineral commodities are covered.The Center's goal is to provide decision makers with the information required to ensure that the Nation has an adequate and dependable supply of minerals and materials to meet its defense and economic needs at acceptable costs related to environment, energy, and economics. In addition to special data releases available through ScienceBase, annual and monthly or quarterly statistical...

A pilot study using discriminant analysis on major oxide and minor element data from 67 chert samples in the Rampart area, southeastern Tanana and southwest Livengood Quadrangles, western Yukon-Tanana Upland, Alaska, generally indicates a unique geochemical signature for the cherts of a given unit.Chert samples from five known type locales were used as standards of comparison: 1)Livengood Dome Chert (Ordovician), 2)Amy Creek unit (Proterozoic to early Paleozoic), 3)Rampart Group (Mississippian to Triassic), 4)Troublesome Creek unit (Devonian), and 5)Permian-Triassic clastic unit (associated with the Triassic-dated gabbro). Samples from the above units were compared to chert from Tanana B-1 area-units of unknown...

The Alaska Geochemical Database Version 3.0 (AGDB3) contains new geochemical data compilations in which each geologic material sample has one best value determination for each analyzed species, greatly improving speed and efficiency of use. Like the Alaska Geochemical Database Version 2.0 before it, the AGDB3 was created and designed to compile and integrate geochemical data from Alaska to facilitate geologic mapping, petrologic studies, mineral resource assessments, definition of geochemical baseline values and statistics, element concentrations and associations, environmental impact assessments, and studies in public health associated with geology. This relational database, created from databases and published...
