Data

These .csv files contain data on the bulk mineralogy and geochemistry of tailings samples from the Ducktown volcanogenic massive sulfide mining district in Tennessee, USA. The reported geochemistry was collected using inductively-coupled plasma optical emission spectroscopy/mass spectrometry (ICP-OES/MS), wavelength-dispersive X-ray fluorescence (WDXRF), lead fire assay-inductively...

This data set represents laboratory measurements conducted on a suite of select 53 pegmatite and host rock samples to better spectrally characterize complex pegmatite minerals. Of these 53 samples that were measured and analyzed, this includes 24 samples collected from the Morefield Mine, Amelia County, VA, six samples from the Martin-Marietta Amelia Quarry, Amelia County, VA, three...

We developed a methodology to estimate maximum CO2 injection rates in subsurface layers across wide geographic areas using inverse modeling-based optimization techniques. We first defined geographic areas where groundwater was too saline to meet the standard for drinking water and where sufficient confining units existed above and below the injection layers. We then assumed concurrent...

Rare earth elements are critical mineral commodities typically extracted together as a group of 15 elements (lanthanides plus yttrium) from either 1) hard rock ores or 2) ion-adsorption clay deposits. The locations of hard rock mines targeting carbonatite and peralkaline magmatic rare earth deposits are well constrained and typically mined using conventional open-pit or underground...

This data release includes a digitized version of the "Statistics by States, lands, products and years" section of the 1981 edition of the Federal and Indian lands coal, phosphate, potash, sodium, and other mineral production, royalty income, and related statistics publication. These data were published by the Conservation Division of the U.S. Geological Survey, which was tasked with the...

The dataset includes 2024-2051 estimates of projected United States Federal mineral rights lands coal production and the resulting greenhouse gas emissions (GHG) from mining, transporting, and combusting that fuel. The data cover six states and 30 coal mines. It is divided into four tables, one of coal production and three of GHG emissions. The coal production is presented with three...

This dataset consists of a 200m raster suitability model for the extraction of nickel laterite in the northern California/southern Oregon, USA region. The primary model is composited from three equally weighted submodels: the relative probability of nickel laterite to be present within the study area (prospectivity); environmental and legal considerations associated with traditional...

Per- and polyfluoroaklyl substances (PFAS) of are of interest due to their persistence and ubiquity in the environment and their potential health and environmental effects. While these compounds have been well studied in the past 10 years, little is known about PFAS in oil and gas produced waters, which are voluminous and have the potential to impact the environment through surficial...

A method was developed to measure the presence and concentration of the organic volatile fatty acids (VFA) formate, malate, lactate, acetate, and propionate in aqueous samples using high performance liquid chromatography (HPLC) and ultraviolet absorbance detection. This dataset includes a method detection limit (MDL) study, along with appropriate quality control samples, used to verify...

The land application of drill fluids is governed by rules established in the Oklahoma Administrative Rules (165:10-7) and permitted by the Oklahoma Corporation Commission (OCC). While data on the volume and location of land application is publicly accessible through the OCC's website, much of the information is in scanned form documents which limits the operability of these data. This...

This data release includes a digitized version of the "Statistics by States, lands, products and years" section of the 1981 edition of the Federal and Indian lands oil and gas production, royalty income, and related statistics publication. These data were published by the Conservation Division of the U.S. Geological Survey, which was tasked with the accounting for Federal lease...

This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered oil and gas resources in the Escondido, Olmos, and San Miguel Formations of the Western Gulf Basin Province, U.S. Gulf Coast Region. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment...
