The United States Geological Survey (USGS) collected a total of 63 samples of surficial sediment from abandoned mine wastepiles, ephemeral channels, nearby outcrops, and background areas representative of the undisturbed lithology within the Free Coinage and Third Term mining districts in the Stansbury Mountains (Krahulec, 2018). The samples were sieved to obtain the less than 177 micron fraction. Geochemical analyses were completed through a third-party contract by AGAT Laboratories. Samples were analyzed for 49 major, minor, and trace elements using Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) methods (Ag, Al, As, Ba, Be, Bi, Ca, Cd,...

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;...

During August of 2014, the United States Geological Survey (USGS) collected a total of 187 surficial sediment and bedrock samples from abandoned mine wastepiles, ephemeral channels below wastepiles, nearby outcrops, and background areas representative of the undisturbed lithology within Emery County, UT. The samples were clustered into four different groups: Buckmaster Draw (BM), Dry Mesa (DM), Cow Flats (CF), and Cedar (C). These samples were sieved to obtain a less than 177 micron fraction, which was homogenized and subjected to a four acid digestion prior to analysis by Inductively Coupled Plasma (ICP) methods. (Ag, Al, As, Ba, Be, Bi, Ca, Cd, Ce, Co, Cr, Cs, Cu, Fe, Ga, In, K, La, Li, Mg, Mn, Mo, Na, Nb, Ni,...

This data release contains model code and input data for, and predictions from, both a dynamic stream dissolved solids and a static baseflow dissolved solids SPARROW (SPAtially Referenced Regression On Watershed attributes) model of the Upper Colorado River Basin for water years 1986-2017. Input data includes information on dissolved solids sources, landscape transport characteristics, and dissolved solids load calibration data from water quality monitoring stations. Model output includes predictions for every reach of total and incremental predicted loads and total and incremental loads from each source. Further details on model development and results are described in Miller and others, 2023.

The Spor Mountain study area is located in the Spor Mountain Range, approximately 42 miles northwest of Delta, Utah. Mining in the Spor Mountain district began in the 1940s and continues to present day. Fluorspar, uranium, and beryllium are the main ores mined(Ege, 2005). From August through September 2013, the United States Geological Survey (USGS) collected a total of 73 samples from abandoned mine wastepiles, channel sediments downslope of wastepiles, and background areas. The samples were sieved to obtain the less than 177 micron fraction. Geochemical analyses were completed through a third-party contract by General Society of Surveillance (SGS) with method ICM40B - Fifty-five major (except Si and Na), rare...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
