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

Grade and tonnage data for disseminated flake graphite deposits

Crystalline graphite is a primary material in lithium-ion battery anodes which are essential in moving towards green energy. Forecasts for 2040 anticipate an order of magnitude increase in graphite demand driven by sustainable development policies to reduce carbon emissions. Domestic production of graphite ceased in the 1980s after a steady decline post-World War I, meaning the United States relie

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

Geological and Pb-isotope data for New England volcanogenic massive sulfide deposits

This dataset accompanies publication “Lead isotopes in New England (USA) volcanogenic massive sulfide deposits: implications for metal sources and pre-accretionary tectonostratigraphic terranes”, published in Canadian Journal of Earth Sciences (see 'Related External Resources' section below). The data encompass Pb-isotope analyses of sulfide mineral separates, mainly galena, as well as whole-sulfi

Database of mineral deposits related to the Mesoproterozoic Midcontinent Rift System (MRS) in the northern United States and northern Ontario, Canada

The Midcontinent Rift System (MRS) of North America is one of the world’s largest continental rifts and has an age of 1.1 Ga (giga-annum). The MRS hosts a diverse suite of magmatic and hydrothermal mineral deposits in the Lake Superior region where rift rocks are exposed at or near the surface. As part of the construction of a database summarizing information on mineral deposits in the MRS, data f

Delta log R total organic carbon estimates for the Tuscaloosa marine shale, U.S.A.

This dataset contains estimated total organic carbon (TOC) calculated using the delta log R (dlogR) method, developed by Passey and others (1990), within BasinMod modeling software for the Tuscaloosa marine shale (TMS) in southwestern Mississippi, U.S.A. BasinMod is a modeling software developed by Platte River Associates, Inc. Using version 2021-03-03 of the software, sonic and resistivity logs a

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

National scale assessment for rare earth elements in dissolved water samples and supporting geochemistry

This dataset is in support of the publication "The addition of 144Nd to routine ICP-MS analysis as a quick screening tool for approximating earth elements (Q-STAR) in natural waters". It contains inductively coupled plasma mass spectrometry (ICP-MS) data from samples analyzed at the National Water Quality Laboratory (NWQL) from April 2021-May 2022. Data listed include estimated neodymium (Nd) conc

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
