Sediment hosted zinc (Zn) and lead (Pb) deposits are the most significant sources of zinc and lead ore globally. Zinc is required to create corrosion-resistant iron and steel products among other applications, and lead is an important element in car batteries and other industrial products. These deposits can also contain significant quantities of silver (Ag), which is commonly used in...

This data release presents whole rock geochemical data and powder X-ray diffraction (XRD) mineralogic data from a suite of mafic and ultramafic geologic units in the United States. One-hundred-twelve samples were analyzed from core and outcrop settings at thirty sites, including from the contiguous United States, Alaska, and Hawaii. Sample localities include some of the large mafic and...

Coal exploration drill-hole lithologic, geophysical, and geochemical data from 657 drilling locations in the western Kentucky Mississippi embayment area are provided in this data release. Eighteen drilling locations have multiple sets of data files. The wells are located in eight counties (Ballard, Calloway, Carlisle, Fulton, Graves, Hickman, Marshall, and McCracken) and were drilled...

This data release provides a list of published data releases that contain coal exploration drill-hole lithologic, geophysical, and geochemical data from drilling locations in several U.S. States. The text (TXT) file associated with this data release lists the State data releases that are available. The text file will be updated as additional drill-hole data releases are published. The...

The National Crude Oil Spill Fate and Natural Attenuation Research Site near Bemidji, Minnesota is the site of a 1979 high-pressure crude oil pipeline rupture. Approximately 1.7 million liters of crude oil spilled onto the glacial outwash aquifer. After remediation and natural attenuation, an estimated 25% of the oil remains in the subsurface today. Groundwater monitoring at the site...

The Ordovician Icebox Formation of the Winnipeg Group has been interpreted as a petroleum source rock within the Williston Basin for over 50 years. Despite limited hydrocarbon production from Winnipeg Group reservoirs and being deeply buried (located below most of the current hydrocarbon producing reservoirs), the petroleum industry continues to periodically drill wells through the...

The U.S. Geological Survey (USGS) collects magnetic susceptibility measurements on in-situ and laboratory rock samples to help identify the sources of anomalies in aeromagnetic surveys in Alaska. Magnetic susceptibility is a measure of how much a material will become magnetized in an applied magnetic field and is the ratio of magnetization, M (magnetic moment per unit volume), to the...

This data release contains the boundaries of assessment units and input data for the assessment of undiscovered conventional oil and gas resources in the Buda limestone reservoir of Texas. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment (NAGA) Project for the assessment of undiscovered oil and gas resources. The assessment unit is...

In 2023, the U.S. Geological Survey conducted a reconnaissance survey of surface-water quality in areas of southern West Virginia and eastern Kentucky that have ongoing and/or historic mountaintop removal mining for coal resources. The water-quality data collected during the survey are collated in this data release.

This data release contains major ion geochemistry (B, Ba, Br, Cl, Ca, Fe, K, Li, Mg, Mn, Na, Si, SO4, Sr) and total dissolved solids measurements from produced water samples collected from petroleum wells in the Paradox and Uinta Basins, Utah. Analyses were conducted at the U.S. Geological Survey laboratories in Reston, Virginia. The release comprises two files: one metadata file and one...

This data release (https://doi.org/10.5066/P13JNYU2) contains neutron scattering intensities of a Niobrara Formation rock sample in the presence of pressurized perdeuterated methane, perdeuterated methane-methane, and perdeuterated methane-ethane mixtures at 60 degrees C. Also provided are the densities and scattering length densities for the various fluid mixtures and modeled accessible...

This data release contains metaproteomics data from subsurface methanogenic communities in an Antrim Shale (Michigan basin, MI) natural gas well. The subsurface microbial communities have interacted with produced waters that were exposed to ambient surficial conditions prior to injection of the produced waters into the well. These data are used in a related publication to understand...
