Fluorescence spectroscopy of ancient sedimentary organic matter via confocal laser scanning microscopy (CLSM) Fluorescence spectroscopy of ancient sedimentary organic matter via confocal laser scanning microscopy (CLSM)
Fluorescence spectroscopy via confocal laser scanning microscopy (CLSM) was used to analyze ancient sedimentary organic matter, including Tasmanites microfossils in Devonian shale and Gloecapsomorpha prisca (G. prisca) in Ordovician kukersite from North American basins. We examined fluorescence emission as a function of excitation laser wavelength, sample orientation, and with respect to...
Database of Central and Eastern North American Seismic Velocity Structure Database of Central and Eastern North American Seismic Velocity Structure
The "Database of Central and Eastern North American Seismic Velocity Structure" involves the compilation of one-dimensional (1D) seismic velocity-depth functions for central and eastern North America (CENA). The present database is an update of the report by Chulick and Mooney (2002) who present a compilation and statistical analysis of 1D seismic velocity-depth functions for North...
Organic Petrography and Diagenesis of Leonardian Mudrocks and Carbonates, Midland Basin, Texas (2018) Organic Petrography and Diagenesis of Leonardian Mudrocks and Carbonates, Midland Basin, Texas (2018)
As part of a larger study, organic petrographic features of Leonardian Wolfcamp A repetitive siliceous and calcareous mudrock and fine-grained carbonate lithofacies cycles occurring in the R. Ricker #1 core from Reagan County, Midland Basin, Texas were evaluated. The objectives of the petrographic investigation were to estimate thermal maturity, identify organic matter types and...
ATR Data from Interaction of kerogen with brine-saturated supercritical carbon dioxide (CO2) and its implications to geologic carbon sequestration and enhanced oil/gas recovery (2018) ATR Data from Interaction of kerogen with brine-saturated supercritical carbon dioxide (CO2) and its implications to geologic carbon sequestration and enhanced oil/gas recovery (2018)
The dataset covers Attenuated Total Reflectance (ATR) measurements taken from altered kerogen in shales from the Woodford formation. The ATR measurements were taken after the samples were run through supercritical CO2 alteration experiments in a brine solution.
Enhanced wildfire at the Frasnian-Famennian boundary and its implications for O2 level and F-F mass extinction: evidence from organic petrology and Os isotope stratigraphy Enhanced wildfire at the Frasnian-Famennian boundary and its implications for O2 level and F-F mass extinction: evidence from organic petrology and Os isotope stratigraphy
In this study, organic petrology and Osmium isotope (187Os/188Os) stratigraphy, major and trace element, and programmed pyrolysis analysis were performed on five outcrop samples from western New York, USA. Seawater Os isotope composition is controlled by radiogenic input from weathering of the ancient land and nonradiogenic input from extraterrestrial and hydrothermal sources (Peucker...
XRD data from study on the impact of thermal maturity on shale microstructures using hydrous pyrolysis (2018) XRD data from study on the impact of thermal maturity on shale microstructures using hydrous pyrolysis (2018)
The dataset covers X-ray diffraction (XRD) applied for mineral determination in shales from the Utica, Excello, Niobrara, and Monterey formations. The XRD was performed prior to modified Rock-Eval pyrolysis, reflectance, organic petrology, and Fourier-transform infrared spectroscopy (FTIR) being employed to analyze geochemical properties; gas adsorption (CO2 and N2) was used to...
