THE MICROFOSSIL ASSOCIATION OF THE UPPER PART OF THE SALESVILLE FORMATION (LOWER MISSOURIAN, PENNSYLVANIAN) NEAR MINERAL WELLS, NORTH-CENTRAL TEXAS
(2021-05-09)The microfossil association of the Salesville Formation (Strawn Group, Missourian, Pennsylvanian) of small foraminifers, fusulinids, conodonts, ostracodes, holothurian sclerites, and rare radiolarians, has received very ... -
A GLIMPSE INTO THE CLIMATE, SEASONALITY, HYDROLOGICAL CYCLE, CARBONATE CHEMISTRY AND MARINE ECOSYSTEM SHIFT OF THE PRE-PETM AND THE PETM USING NCAR CESM1.2
(2023-05-19)**Please note that the full text is embargoed until 05/16/2025** ABSTRACT: The Paleocene-Eocene Thermal Maximum (PETM, ~56 my ago, 170,000y event) is characterized by a negative δ13C excursion into the atmosphere. This ... -
Machine Learning-based Methods for the Segmentation of Scanning Electron Microscopy Images of Fine-Grained Shale Samples
(2022-12-15)The segmentation of scanning electron microscopy (SEM) images is critical yet time-consuming for geological studies, as it will need to differentiate the boundaries for different mineral objects to facilitate subsequent ... -
A Comprehensive Analysis of the Evolution of Coastal Flooding in Texas and Louisiana for Application in Risk Assessment
(2022-12-09)Coastal communities of the northern Gulf of Mexico have historically been at risk of flooding from tropical cyclone induced storm surge and extreme precipitation. Relative sea level rise resulting from a combination of ... -
AGE, PROVENANCE AND TECTONIC IMPLICATIONS OF LATE PALEOZOIC VOLCANIC TUFFS IN SOUTHWEST LAURENTIA
(2022-08-17)Assembly of the supercontinent Pangea is among the most important tectonic events in late Paleozoic Earth history. The diachronous Laurentia-Gondwana collision destroyed the intervening subduction zone(s) of the Rheic ... -
REMEDIATION OF CONTAMINATED DUMPSITE SOIL: AN EVALUATION OF SOIL AMENDMENTS IN COMBINATION WITH PHYTOREMEDIATION
(2022-08-24)Contamination of soils and water from open dump site leachate is a frequent problem in developing nations. Water supplies are threatened when water percolates through the waste, bringing with it a variety of substances, ... -
NANOPETROPHYSICAL CHARACTERIZATION OF THE UPPER MANCOS SHALE IN THE SAN JUAN BASIN, NEW MEXICO, U.S.A.
(2022-09-01)The San Juan Basin is no stranger to oil and gas production and the Mancos Shale is one of the formations of the basin that had been producing petroleum since the early 1920’s as conventional, and recently as, unconventional ... -
