40Ar/39Ar age variations among cogenetic feldspars from the Benson Mines, New York
(2016-08-05)
The alkali feldspar group constitutes one the most common mineral groups of Earth’s crust. The 40Ar/39Ar method for dating potassium feldspars has proven to be a powerful analytical tool for evaluating low-temperature ...
40Ar/39Ar Ages of Feldspar and Muscovite from the Source and Detritus of the French Broad River, North Carolina
(2016-08-08)
As the westernmost metamorphic belt of the Appalachians, the Blue Ridge has been the subject of many geochronology studies. The Blue Ridge experienced high-grade deformation and peak metamorphism during Taconic orogeny, ...
40Ar/39Ar Ages of Muscovite from the Western Blue Ridge and Talladega Belt, Georgia and North Carolina
(2008-05-15)
Radiometric age constraints regarding the timing of metamorphism in the western Blue Ridge province of the southern Appalachians have been too limited or uncertain to enable broader correlation and understanding of Taconian, ...
40Ar/39Ar Dating of Detrital Muscovite and Sediment Compositional Analysis of the Pottsville Formation in the Black Warrior basin in Alabama: Implications for Tectonics and Sedimentation
(2012-11-05)
The Greater Black Warrior basin, including the Cahaba and Coosa synclinoria and the Black Warrior basin, contains the thickest preserved accumulation (ca. 2 km) of sediment in the Appalachian-Ouachita foreland. 40Ar/39Ar ...
Adaptation and Comparison of Machine Learning Methods for Geomorphological Mapping and Terrace Prediction: A Case Study of the Buffalo River, Arkansas
(2017-05-31)
Working with a high-resolution LiDAR dataset, this research adapts existing techniques from machine learning to the problem of predicting general and specific geomorphic features in the complex terrain of the Buffalo River ...
Analysis of a drill core from the central uplift of Flynn Creek impact structure, Tennessee
(2017-04-25)
Flynn Creek impact structure is a small, asymmetric marine impact structure located in north-central Tennessee that formed when a hypervelocity impact occurred in an ancient shallow marine environment, with the target ...
Analysis of Mudrock Lithofacies and Hydrocarbon-Source Potential of the Middle Ordovician Athens Shale, Alabama Fold and Thrust Belt
(2017-04-18)
Lithologic, petrologic, and geochemical studies were performed on the Ordovician Athens Shale, with a focus on a 140-ft-thick core section recovered near Calera, Alabama, supplemented by observations of limited outcrop ...
Assessing Transformation of Trace Metals and Crude Oil in Mississippi and Louisiana Coastal Wetlands in Response to the Deepwater Horizon Oil Spill
(2012-06-28)
On April 20, 2010, the drilling rig Deepwater Horizon exploded in the Gulf of Mexico, resulting in the release of about 5 million barrels of crude oil into the environment. Coastal wetlands are particularly susceptible to ...
Bioremediation of an Arsenic-Contaminated Site, Using Sulfate-Reducing Bacteria, Bay County, Florida
(2016-08-05)
In this study an in-situ bioremediation field demonstration project using sulfate-reducing bacteria was conducted at an As-contaminated site, in Bay County, Florida. The background levels of As ranged from 0.13 to 0.34 ...
Bioremediation of Arsenic Contaminated Groundwater in Northwest Florida: Mineralogy, Geochemistry, and Microbiology Changes
(2017-04-21)
This research demonstrates that the stimulation of natural sulfate-reducing bacteria (SRB) in groundwater can precipitate biogenic pyrite nanoparticles that play an active role in sequestering dissolved arsenic from ...
Biotic Composition and Taphonomy of an Upper Cretaceous Konservat-Lagerstätte: The Ingersoll Shale, Eutaw Formation, Eastern Alabama
(2007-08-15)
The Ingersoll shale is a thin (<1m), laterally restricted clay lens within the Upper Cretaceous (Santonian) Eutaw Formation, Russell County, eastern Alabama. The clay lens represents abandoned tidal creek fill within an ...
Characterizing the Geological and Geochemical Properties of Selected Gas Shales and their Thermal Maturation in the Black Warrior Basin, Alabama
(2014-07-22)
This study will focus on selected gas shale’s, geological and geochemical properties in Alabama’s Black Warrior Basin, which contains Cambrian through Mississippian shales; these gas-shales that may potentially produce ...
Clustered Seismicity in Alabama: Natural or Anthropogenic?
(2017-07-27)
Seismicity in the central and eastern U.S. is typically characterized by low-magnitude earthquakes (M < 4) with a random distribution that occur in areas of low to moderate strain rates. An unprecedented increase in ...
A Comparative Spatial Analysis of Two Communities from the Hickory Ground Site in Wetumpka, Alabama
(2014-12-09)
This thesis presents analyses on the intra-site spatial arrangement of two communities from the Hickory Ground site, 1EE89, in Elmore County, Alabama. Spatially referenced archaeological datasets of a Protohistoric community ...
A Comparative Study of Site Response in Western Washington Using Earthquake Data
(2014-08-18)
Broadband and strong motion seismic data from three moderate to large earthquakes were used to determine site response characteristics in the Seattle and Tacoma, Washington, area. The three earthquakes chosen for analysis ...
Distribution of encrusting foraminifera at Cat Island, Bahamas: Implications for foraminiferal assemblages in the geologic record
(2015-06-05)
Benthic foraminifera that are cemented by calcium carbonate or are otherwise firmly fixed to hard surfaces are commonly known as encrusting foraminifera. Very few studies focus on the use of encrusting foraminifera as ...
