These data are for a geochronologic study of emplacement ages for plutons of the Cretaceous Idaho batholith and detrital zircon ages for metasedimentary rocks, west-central Idaho. Zircon from six samples of discrete plutons across a regional transect were dated by sensitive high resolution ion microprobe (SHRIMP). SHRIMP U-Pb ages of igneous rocks connect the igneous activity to structural history, crustal depths, and origins of epigenetic gold-silver-antimony-tungsten±mercury mineral deposits. Zircon from four samples of metasedimentary rocks in the southern part of the central Idaho mineral province were dated—three by laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) methods and one by SHRIMP...

This data release is the result of a hydrogeochemical sampling campaign during summer 2021 to investigate whether high resolution geochemical analysis of waters for element chemistry can be used as an exploration tool for identifying gold-rich occurrences in parts of the Big Delta B-1 and B-2 quadrangles, within the Yukon-Tanana Upland region, Alaska. Historical USGS conventional stream sediment geochemical data yielded variable indications of geochemical anomalies in conventional stream sediment geochemistry results, probably related to relative exposure of mineralized rock. Previous studies of waters in the Pogo area (western part of current study) utilized conventional analytical methods not capable of measuring...
This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over Columbia, South Carolina, and the surrounding region. The airborne data collection was funded by the U.S. Geological Survey (USGS) Earth Mapping Resource Initiative (Earth MRI) with goals of better understanding placer deposits containing critical mineral resources titanium, zirconium, and rare earth elements and of imaging the crystalline basement partly buried beneath Atlantic Coastal Plain sediments. The survey was flown northwest of and slightly overlapping an airborne magnetic and radiometric survey collected in 2019 (Shah, 2020). The northwestern boundary of the 2020 survey lies within the...

Hydrothermally altered rocks, particularly if water saturated, can weaken stratovolcanoes, thereby increasing the potential for catastrophic sector collapses that can lead to far-traveled, destructive debris flows, which are the largest volcanic hazards for Mount Adams and Mount Baker. Evaluating the hazards associated with such alteration is difficult because much of the alteration is obscured by ice and its depth extent is unknown. Intense hydrothermal alteration significantly reduces the resistivity and magnetization of volcanic rock and therefore hydrothermally altered rocks are identified with helicopter electromagnetic and magnetic measurements at Mount Baker and Mount Adams. High resolution magnetic and electromagnetic...

The titanium concentrations were obtained from a data set that is called the "National Geochemical Survey." This data set, as well as its documentation, are available in U.S. Geological Survey Open-File Report 2004-1001 (https://mrdata.usgs.gov/geochem/doc/home.htm). The titanium concentrations were measured in 3,457 samples of stream sediments from the coastal plain of the southeastern United States; this area includes parts of Virginia, North Carolina, South Carolina, Georgia, Florida, and Alabama. The samples were collected between 1975 and 1999 during several field surveys, and the concentrations were measured using inductively coupled plasma-atomic emission spectrometry.

This data release compiles the whole-rock geochemistry, X-ray diffraction, and electron microscopy analyses of samples collected from the uranium ore bodies of two mined-out deposits in the Grand Canyon region of northwestern Arizona—the Hack II and Pigeon deposits. The samples are grab samples of ore collected underground at each mine by the U.S. Geological Survey (USGS) during the mid-1980s, while each mine was active. The Hack II and Pigeon mines were remediated after their closure, so these data, analyses of samples in the archives of the USGS, are provided as surviving, although limited representations of these ore bodies. The Hack II and Pigeon deposits are similar to numerous other uranium deposits hosted...
There is a growing demand for commodities (elements, compounds, minerals) used in today's advanced technologies. Critical minerals are usually found in ore deposits that are deemed vital to economic and national security. The National Geochemical Database on Ore Deposits: Legacy data (NGDOD) contains chemistry and geologic information for nearly 30,000 historic ore and ore-related rock samples from mineral deposits and mining districts in the United States. Geochemical data sets from various mineral deposits were submitted by geologists of the "Systems Approach to Critical Minerals Inventory, Research, and Assessment" (SACM) within the U.S. Geological Survey Mineral Resource Program (MRP). The data sets represent...

This data release provides the description of U.S. sites that include mineral regions, mines and mineral occurrences (deposits) that have a contained resource and (or) production of tellurium metal greater than 1 metric ton. For this data release, only one deposit in the U.S. with historic production records was found: Butte, Montana. We did not locate any deposits in the U.S. that list Te resources. Production facilities, such as the ASARCO LLC’s copper refinery in Amarillo, Texas are not included within this database. Tellurium is necessary for strategic, consumer, and commercial applications. The primary use for tellurium is for Cd-Te film solar cells. Other uses are as an alloying additive to steel to improve...
X-Ray diffraction (XRD) data for bulk sediment and clay separations taken from cores from Bristol Dry Lake, California and geothermal springs from Paoha Island (Mono Lake), California. The data were collected for two separate projects: (1) determining the source of lithium in Bristol Dry Lake (BDL), and (2) determining the mechanism of sinter formation on Paoha Island, Mono Lake. The data from BDL were collected in collaboration with Standard Lithium Ltd. who drilled 6 new proprietary wells in 2017 and 2018 on the playa. The wells were not cored, but cuttings were available for sampling a few months after the drilling was completed. The wells were up to 1500 feet deep. Cuttings were kept in the dark in sealed plastic...
Stable isotope compositions (the ratios deuterium/hydrogen, oxygen-18/oxygen-16, and sulfur-34/sulfur-32) are reported for alunite, jarosite, kaolinite, silica, cinnabar, marcasite, and native sulfur from outcrops in and around the workings of the Sulphur Bank mercury mine, Lake County, California, and chemical compositions are reported, from electron microprobe analyses, for alunite and buddingtonite. Isotope analyses are given also for hydrogen sulfide gas from active fumaroles and for soluble sulfate in samples of mine waste. The waste results reflect fine grained material (particles less than 0.063 millimeter in diameter) that were taken from composites, each composite representing a particular waste pile that...
