The Great Smokey Group and the Mineral Bluff Group of the southern Appalachians Blue Ridge contain units of metaconglomerate that contain stretched quartz pebbles. Quartz pebbles have been widely used as strain markers in conglomerates....
Two major thrust systems are located along the eastern Blue Ridge â western Blue Ridge boundary in the Alabama and Georgia Appalachians. The pre-metamorphic Hillabee thrust is near the trailing edge of the Talladega belt thrust sheet...
The study conducted U-Pb isotopic dating of the pitchblende mineralization of the Coles Hill uranium deposit in Pittsylvania County, VA. The ore body is found along the Chatham fault and within the Martinsville Igneous Complex. In...
Department of Energy (DOE) proposed an in situ remediation approach to radioactive metal contaminants in DOE complex through calcite mineral precipitation facilitated by hydrolysis of urea (ureolysis). One of the ureolysis products, ...
This dissertation research has used stable and radioactive isotope techniques to address several important issues in paleoclimate and paleoecoloical research which includes the reliability of using stable carbon isotope composition of...
The dissertation reports a series of hydrological studies that relates to seawater intrusion in a karst aquifer. In the Woodville Karst Plan (WKP), karst conduit system is well developed and directly open to the Gulf of Mexico that...
The Cartersville area in Georgia lies at the junction between the Alabama Recess and the Tennessee Salient. The rocks here are the easternmost exposures in the foreland fold and thrust belt of the southern Appalachians. It is bounded to...
Well-developed karst aquifers contain high permeability limestone matrix and much higher conductive conduits, this dual porosity system behaves totally different from other kinds of aquifers and becomes a challenging task for modern...
The southeastern Blue Ridge hosts a suite of metamorphic rock units that provide insight to the Neoproterozoic to Paleozoic tectonic influences that impacted the Laurentian continent. The Ashland-Wedowee-Emuckfaw belt of the southernmost...
The goal of this project is to combine gravity measurements with geologic observations to better understand the "Big Bend" of the San Andreas Fault (SAF) and its role in producing hydrocarbon-bearing structures in the southern Central...
The thesis presents and evaluates five new gravity constrained structural cross-sections about the Palos Verdes and Cabrillo faults of southern California. They both have been active since the Miocene, however the Palos Verdes fault zone...
The goal of this investigation was to determine whether highly accurate sampling and dating methods could be employed to develop a high-resolution history of barrier evolution and sea-level change. The focus of the study was St. Vincent...
This study investigates the effects of geological structure of the aquifers and the chemistry of water by testing the water chemistry variation such as the main cations (Na+, K+, Ca2+, Mg2+) and anions (Cl-, SO4 2-, HCO3 -) and TDS from...
The overall goal of this project is to better understand geologic characteristics of the Raton Basin. The Raton Basin is a Rocky Mountain foreland basin that contains Pennsylvanian through modern sedimentary rocks. The current structure...
The Panamanian Isthmus presents an ideal opportunity to study arc magmatism, arc-hotspot interaction, and the effects of the South America-Panama collision. These effects include changing mantle wedge compositions and localized tectonic...
The Paleozoic growth of the eastern margin of the North American continent is exemplified by the amalgamation of a series of terranes due to the closure of intervening ocean(s) and the obduction of fragments of oceanic and continental...
A Study of the Lithological and Petrographical Changes Across the Eocene-Oligocene Transition of the Ocala and Suwannee Formations in Northern Florida and Southern Georiga
With so few Eocene outcrops throughout Florida, it is difficult to study the Eocene-Oligocene boundary between the Ocala and Suwannee Limestone. This study provides a more detailed lithological description of the differences of rocks on...
The Oligocene-Miocene collision between Panama and South America significantly influenced ocean currents, global climate, and species diversification. Intraplate deformation of the Panama Block also played an important role in the...
In the southernmost Appalachians, bimodal volcanics of Pumpkinvine Creek Formation (PCF) and its proposed equivalent, the Hillabee Greenstone (HG) have indistinguishable ages (~460 Ma) and trace element-REE pattern similar to an arc/back...
Investigations of the Southern Appalachian Eastern Blue Ridge of East Central Alabama and West Central Georgia Using Structural, Geochemical, and Thermobarometric Analyses
Recent work in the southern Appalachians has identified the remnants of a historically critical Ordovician back-arc basin that now resides in the Talladega belt, eastern Blue Ridge, and Inner Piedmont terranes of Alabama, Georgia and...
The southern Appalachian Inner Piedmont in east central Alabama and west Georgia consists of two tectonically separated Ordovician lithotectonic units: the structurally upper Dadeville Complex and the underlying Opelika Group. The...
Stable Carbon and Oxygen Isotopes in Cetaceans and in Terrestrial Herbivores as Indicators of Diet, Movement and Environment: Paleoceanographic, Paleoclimatic and Paleoecologic Applications
Stable oxygen and carbon isotopic compositions of modern and fossil cetacean teeth and bones were analyzed to examine if and how they reflect the diet, habitat preference and migratory patterns of modern whales and to reconstruct the...
The Dadeville Complex is a large klippe located in the Alabama Inner Piedmont of the southern Appalachian orogen lying immediately above rocks of the eastern Blue Ridge and Brevard Zone, in the core of the Tallassee synform. Structural...
Paleotempestology is the study of long-term regional storm history from geological proxy evidence. This relatively recent field of geology offers a glimpse at tropical cyclone activity extending back into geologic time. Historic...
Employing stable carbon and oxygen isotope analyses (including d13C and d18O of structural carbonate in mammalian tooth enamel and d18Op of fish bone samples) to reconstruct paleoecology and paleoenvironments, this dissertation strives...
