This data release contains geochemical and spectroscopic laboratory results associated with the journal article "Middle-Late Holocene paleolimnological changes in central Lake Tanganyika: Integrated evidence from the Kavala Island Ridge (Tanzania)". Data include bulk organic geochemistry, organic stable carbon isotope, and infrared spectroscopic analyses. Location for LT-TANG17-9B-1U-1: latitude: -5.952900, longitude: 29.639700. Coring site is located ~ 14 km offshore in ~ 420 m of water.

This data release is a compilation of vitrinite reflectance (Ro) data from the Southwestern Wyoming Province in Wyoming, Colorado, and Utah. The data includes about 1,200 Ro measurements from wells drilled for oil and gas exploration and production, coal test holes, and outcrop sections.

This data release contains data associated with the journal article, “Comparison of δ13C Analyses on Individual Foraminifer (Orbulina universa) Shells by Secondary Ion Mass Spectrometry and Gas-Source Mass Spectrometry”. Data tables are comprised of stable carbon isotope (δ13C) measurements of planktic foraminifer (Orbulina universa) shells measured by secondary ion mass spectrometry (SIMS) and conventional gas-source mass spectrometry (GSMS). The data release also includes the R code used for statistical analysis and figure generation, as well as scanning electron microscope (SEM) images of O. universa shells taken before and after SIMS analysis.

This compilation presents total organic carbon and pyrolysis analysis data for the Pierre Shale, Niobrara Formation, and other Cretaceous marine shales in the Raton Basin-Sierra Grande Uplift Province. The data was used to characterize these potential source rock intervals in support of the oil and gas resource assessment in the province. The data was compiled from the publicly available files at the USGS Core Research Center in Lakewood, Colorado and from published literature.

This Data Release contains lanthanide (i.e., rare earth element, REE), yttrium (Y), and scandium (Sc) concentrations for oil shales and kerogens isolated from those presented in the associated journal article "Role of Organic Matter and Thermal Maturation in Rare Earth Element Partitioning in the Middle Devonian Sequence of the Appalachian Basin". This dataset provides REE content for a diverse range of organic-rich mudstones from around the world with samples from the Cambrian through Eocene Periods.

This dataset is associated with a USGS publication "Assessment of Undiscovered Oil and Gas Resources in the Eagle Ford Group and Associated Cenomanian-Turonian Strata, U.S. Gulf Coast, Texas, 2018" and summarizes data generated by the author for the publication using IHS Harmony DeclinePlus software. Data includes average estimated ultimate recoveries per square mile for three continuous oil assessment units with location information. Data is derived from IHS Markit data. No proprietary information is contained in this release.
