Coal mine drainage effluents and associated solids major, trace, rare earth element and radium concentrations collected from Pennsylvania, USA

Discharges from abandoned coal mines and associated mine wastes represent historic and persistent sources of pollution in the Appalachian Basin, United States. In this study, we conducted the first-ever survey of radium (Ra) in coal mine drainage (CMD) water and solid samples in the United States. Samples were collected from 4 untreated coal mine discharges and 9 treated coal mine discharges (i.e.

Shallow Coal Exploration Drill-Hole Data for Arkansas

Shallow (300 ft or less) coal exploration drill-hole data from 692 wells located in Arkansas are provided in this data release. The well locations extend over nine Arkansas counties and were drilled between 1975 and 1977, primarily by Phillips Petroleum Company (Phillips). Also included in the dataset are 79 wells drilled by Tenneco. The data were donated to the U.S. Geological Survey (USGS) in 20

Microscopic Images of Leonardite and Humate Biochar: Using Reflected Light Microscopy in Biochar Characterization

Biochar is a carbon-rich substance that is derived through the thermochemical conversion of biomass. Biochar is recognized for its significance in environmental applications and sustainable agriculture. In an effort to comprehend how the source material and pyrolysis parameters influence its properties, reflected light microscopy is being used to produce microscopic images for analysis of selected

Carbon Dioxide Storage Resources-Wind River Basin: Chapter O, Spatial Data

The storage assessment unit (SAU) is the fundamental unit used in the National Assessment of Geologic Carbon Dioxide Storage Resources project for the assessment of geologic CO2 storage resources. The SAU is shown here as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the assessment interval. Individual SAUs are defined on the basis of common geologic and h

Chemistry data from leachates of hydraulic fracturing proppants collected from southeastern New Mexico, 2018-2019

Proppants used during hydraulic fracturing of oil and gas wells are manufactured to maximize petroleum yield by controlling the size, shape, density, and strength of the proppant material. The most common types of proppants are mined silica sand and manufactured ceramics, some of which are further modified with organic resin coatings to improve performance. Much of the work on the environmental an

Screening geochemistry, gas chromatography, and solid bitumen reflectance data in the Bakken petroleum system, Williston Basin, USA

Thirty-two organic-rich samples from the lower and upper shale members of the Devonian–Mississippian Bakken Formation were collected from eight cores across the Williston Basin, USA, at depths (~7,575–11,330 ft) representing immature through post peak oil/early condensate thermal maturity conditions. Reflectance results were correlated to programmed temperature pyrolysis parameters [hydrogen index

U.S. Geological Survey National Produced Waters Geochemical Database (ver. 3.0, December 2023)

During hydrocarbon production, water is typically co-produced from the geologic formations producing oil and gas. Understanding the composition of these produced waters is important to help investigate the regional hydrogeology, the source of the water, the efficacy of water treatment and disposal plans, potential economic benefits of mineral commodities in the fluids, and the safety of potential

Detrital Zircon U-Pb and Hf isotope data from selected Appalachian rivers

This data release contains zircon U-Pb (n=1467) and Hf (n=332) data for five modern rivers (Connecticut, Susquehanna, Roanoke, Peedee, and Chattahoochee) draining the Appalachian mountain belt. The data show that zircon crystallization ages are characterized by several discrete populations that often correspond with orogenic episodes in the Mesoproterozoic and Paleozoic, with distinct differences
