RECOMPILATION OF LITHOLOGICAL PROXIES ACROSS THE PERMIAN-TRIASSIC BOUNDARY
(2020-12-09)The largest mass extinction occurred near the Permian-Triassic boundary (PTB; 251.902 ± 0.024 Ma; Shen et al., 2011), with the demise of more than 90% of marine species and 70% of terrestrial species. This study expands ... -
Reducing Lead Bioavalability In Soil By Adding Apatite II
(Environmental & Earth Science, 2012-04-11)This study was an examination of phosphate-induced immobilization of lead (Pb) in soils through addition of apatite II (fish bone material). The sources of Pb minerals in the soils examined in this in situ remediation study ... -
Reducing Pb Bioaccessibility In Soil Through The Addition Of Apatite II
(Environmental & Earth Science, 2014-03-12)This study was an investigation of the bioaccessibility of Pb in the presence of phosphate acting as an immobilizing constituent in the form of fish bone material, specifically Apatite II. Phosphate-induced Pb immobilization ... -
Regional Stratigraphy of the Marble Falls Formation and Underlying Late Mississippian to Early Pennsylvanian Deposits, Fort Worth Basin, North-Central Texas, USA
(2015-12-09)The Early Pennsylvanian Marble Falls Formation in the Fort Worth Basin (FWB) of North-Central Texas was deposited in a broad carbonate ramp system during the initial stages of Ouachita orogenesis. It extends across an ... -
Removal Of Butylene And Propylene Gas Using Biofiltration
(Environmental & Earth Science, 2010-03-03)Air pollutants are produced from a variety of anthropogenic activities such as food production, wastewater treatment plants, painting, industrial activities, and biomass combustion. Such pollutants are becoming a cause ... -
The Role Of Remnant Native Vegetation And Management Strategies In The Reclamation Of Native Prairie Plant Communities
Native prairie ecosystems are diminishing in Texas along with their ecosystem services. In order to restore the native prairie ecosystems and their services as a whole, the native prairie plant communities on which they ... -
Sandstone Injectites Record Pre-, Syn-, And Post-folding Deformation At Sheep Mountain Anticline, Wyoming
Sandstone injectites ranging from 30 m to over 1 km in outcrop length intrude the Cretaceous Mowry Formation in the vicinity of Sheep Mountain Anticline (Bighorn Basin, WY). These injectites were sourced by the Peay Member ... -
Sedimentology, ichnology, depositional environment interpretation, and reservoir characterization in the Cotton Valley Formation Sandstone in the Amoco Grace Lowry #1, Harrison County, Texas
(Geology, 2010-07-19)The Cotton Valley formation in east Texas and north Louisiana is a proven hydrocarbon producing tight gas sand reservoir. Understanding the depositional environment, sandstone body geometries and reservoir properties are ... -
Seismic Analysis and Petrophysical Evaluation of the Pennsylvanian Rasberry Reef Phylloid Algal Carbonate Mounds in the Knox-Baylor Trough, Knox County, Texas
(2018-02-27)The Ellis Ranch Wildcat field in Knox County, Texas produces from an isolated carbonate platform located on the northern flank of the Knox-Baylor Trough. The platform is composed of the Desmoinesian aged Caddo Limestone ... -
Seismic Inversion In Fluvial Reservoirs: Building A Geologic Model-based Inversion For The Stratton Field 3D Survey
(Geology, 2010-03-03)Seismic surveys, in particular 3-D surveys, are an important tool for imaging geologic structure in the subsurface; they are routinely applied to map structural trends and geometry to define the reservoir structure. Many ... -
Selenium Speciation Along A Groundwater Flow Path In The Carrizo Aquifer, Southeastern Texas, USA
(Geology, 2007-08-23)Selenium concentration and speciation [Se (VI), Se (IV) and Se (-II)] was determined along a flow path in the Carrizo Sand aquifer (southeastern Texas). Groundwater sampling was carried out in March 2006, from ten wells ... -
SENSITIVITY OF OXYGEN MINIMUM ZONES DUE TO CARBON DIOXIDE RADIATIVE FORCING USING CESM 1.2
(2019-04-25)Anthropogenic-induced climate change is occurring at an unprecedented rapid rate, compared to the geologic past. In this study, CO2 stabilization scenarios (1x, 2x, and 4x preindustrial atmospheric pCO2 levels) utilizing ... -
Simulation Of Climate Across the Permian-Triassic Boundary with a Focus on Phytogeographical Data Analysis
(2018-12-06)The present study aims at reconstructing the paleoclimate across the Permian-Triassic Boundary (PTB, 251.9 ± 0.024 Ma) which encompasses one of the major mass extinction events of the Earth’s history. Results are analyzed ... -
Southern Illinois Paleoclimate Determined From Variations In Iron Oxide Content
(Geology, 2008-08-08)Diffuse reflectance spectroscopy was used to determine the relative abundance of the iron oxides hematite and goethite in a loess and paleosol sequence from an unglaciated area of southern Illinois. Factor analysis of ... -
