Application of phosphate and surfactant-modified zeolite for remediation/attenuation of trace elements in soil and coal fly ash

Neupane, Ghanashyam (University of Alabama Libraries, 2012)

This dissertation presents results of a research work aimed at understanding and addressing trace element contamination sourced by coal fly ash and arsenic trioxide herbicide. Both alkaline and acidic fly ash samples were ...
U-Pb zircon geochronology, Hf isotope and trace element geochemistry of a unique lower crustal - upper mantle section of a dying slow-spreading mid-ocean ridge (Macquarie Island, Southern Ocean)

Jeffcoat, Charles Ryan (University of Alabama Libraries, 2012)

Macquarie Island, located in the Southern Ocean, is a section of subaerially exposed oceanic crust formed at the now extinct proto-Macquarie, slow-spreading, mid-ocean ridge. Macquarie Island is unique among oceanic ophiolite ...
Using 3-D seismic inversion data as a tool for predicting porosity in the Wilburton gas field, Arkoma Basin, southeastern Oklahoma

Fuchs, Jeffrey Charles (University of Alabama Libraries, 2012)

Understanding and identifying changes in rock properties over an area is critical in characterizing a reservoir. In order to identify porosity changes, a 3-D seismic inversion volume was inverted for acoustic impedance in ...
Structural geometry of the frontal Ouachitas-Arkoma basin transition zone in Western Arkansas

Yezerski, Donald Jordan (University of Alabama Libraries, 2013)

The Choctaw Fault and Ross Creek Fault are the leading-edge thrusts of the Ouachita fold-thrust belt and form the southern boundary of the Arkoma foreland basin in Oklahoma and Arkansas, respectively. Strain partitioning ...
Using linear inverse methods and finite element models to explore sensitivity to homogeneous elastic half-space assumptions in deformation models of the 2000 eruption of Hekla volcano, Iceland

Compton, Sarah K. (University of Alabama Libraries, 2013)

On February 26, 2000, the 12-day, 18th historic eruption of Hekla volcano in Iceland began with an explosive Subplinian eruptive column and pyroclastic basaltic flows fed by column collapses (Höskuldsson et al., 2007). ...
Evaluation of submarine groundwater discharge and groundwater quality using a novel coupled approach: isotopic tracer techniques and numerical modeling

Ellis, John H. (University of Alabama Libraries, 2013)

It has been recognized that submarine groundwater discharge (SGD) may be one of the principal pathways for delivering nutrients to surface water bodies, resulting in eutrophication of many nearshore coastal areas throughout ...
Laboratory incubations of Macondo oil-derived hydrocarbons in Alabama salt marsh sediments and water

Fields, Daniel (University of Alabama Libraries, 2013)

In order to better understand the impact of the BP Deepwater Horizon and future oil spills on the Gulf of Mexico coast this study assesses the variation of alkanes and polycyclic aromatic hydrocarbons (PAH) in coastal ...
Investigating the presence and distribution of organic components in bacterial magnetite

Spry, Jacob (University of Alabama Libraries, 2013)

The formation of magnetites within magnetosomes is subjected to highly controlled biomineralization processes by bacteria. Similar biominerals have been observed to contain occluded ("intra-crystalline") organics, revealing ...
Microfacies analysis, depositional environments and sequence stratigraphy of the late Cretaceous Karababa and Derdere formations in the Cemberlitas oil field, Adiyaman, Southeastern Turkey

Mulayim, Oguz (University of Alabama Libraries, 2013)

The frontal belt of the southeastern Anatolia fold-thrust belt in Turkey contains several small to mid-size oil fields, producing from Cretaceous carbonate of the Mardin Group. Many oil fields are located narrow, asymmetrical ...
Regional Norphlet facies correlation, analysis and implications for paleostructure and provenance, eastern Gulf of Mexico

Hunt, Bryan Wallace (University of Alabama Libraries, 2013)

Norphlet Formation paleotransport is controlled by wind and structure. Facies analysis of the Norphlet Formation shows that structurally routed wadis and alluvial fans are the primary methods for introducing sediment into ...
Crustal structure of the eastern Gulf of Mexico

Nwafor, Emeka D. (University of Alabama Libraries, 2013)

The Gulf of Mexico initiated in the Late Triassic as South America and Africa separated from North America during the break up of Pangea. Previous studies indicate three models for the opening of the GOM. These include ...
Magmatism, metamorphism, and deformation in the Mountain Home Metamorphic Complex, Blue Mountains Province, Oregon, and its role in late Jurassic deformation in the western North American Cordillera

Anderson, Bryan Scott (University of Alabama Libraries, 2013)

Orogenesis in the Blue Mountains Province (BMP) of NE Oregon involved the accretion of various tectonostratigraphic terranes in concert with syn-tectonic magmatism. Timescales of deformation, metamorphism and magmatism in ...
Detrital zircon U-Pb age constraints on the provenance of the late Jurassic Norphlet Formation, eastern Gulf of Mexico: implications for paleogeography

Lovell, Thomas R. (University of Alabama Libraries, 2013)

Detrital zircon U-Pb geochronology and thin-section petrology of core samples taken from onshore Alabama and offshore federal lease blocks, including Destin Dome, Pensacola, and Mobile, constrain sediment provenance for ...
Deepwater Horizon oil spill: using microcosms to study effects of crude oil in coastal sediments

Rentschler, Erika Kristine (University of Alabama Libraries, 2013)

Approximately 4.9 million gallons of crude oil traveled with ocean currents to reach the Gulf coast after the Deepwater Horizon oil drilling rig explosion. Microcosm experiments were conducted to determine how oil contamination ...
Metamorphism of the Wenatchee Ridge orthogneiss: a combined application of geochronology and phase equilibrium modeling

Holler, Robert (University of Alabama Libraries, 2013)

Pressure and temperature estimates from phase diagram models indicate that the Wenatchee Ridge orthogneiss is the deepest exposed segment of the crust in the Nason terrane of the Cascades crystalline core, WA. Peak metamorphic ...
Utilizing high-precision geochronology to evaluate the rates of geologic processes

Gatewood, Matthew Patrick (University of Alabama Libraries, 2013)

High-precision U-Pb zircon and Sm-Nd garnet isotopic ages are used to investigate the rates of geologic processes over timespans of millions of years and spatial scales ranging from mountain belts (km) to thin-sections ...
Kinematic analysis of the southern Funeral Mountains: implications for Cenozoic extensional tectonics

Lutz, Brandon Michael (University of Alabama Libraries, 2013)

Map-view area balance of extensional strain in the west-central Basin and Range indicates that the area has undergone 250-300 km of upper crustal extension. Consistent 25-30 km moho depth across the area suggests that the ...
δ<super>15</super>n in mollusk shells as a potential paleoenvironmental proxy for nitrogen loading in chesapeake bay

Black, Heather Dawn (University of Alabama Libraries, 2014)

Crassostrea virginica is one of the most common oyster species in North America and is frequently found in archaeological sites and sub-fossil deposits, especially in the eastern US. Although there have been several ...
Effects of the 1982-1983 El Niño mega event on bivalve mollusk biomineralization

Nicosia, Alexandra Rose (University of Alabama Libraries, 2014)

Marine bivalve mollusks are valued as climate change recorders due to predictable growth rates and the recording of the ambient seawater environment into their shells (e.g., temperature, dissolved inorganic carbon (DIC)). ...
Rifting and subduction in the Papuan peninsula. Papua New Guinea: the significance of the Trobriand tough, the Nubara strike-slip fault, and the Woodlark Rift to the present configuration of Papua New Guinea

Cameron, Milo Louis (University of Alabama Libraries, 2014)

The calculated extension (~111 km) across the Woodlark rift is incompatible with the > 130 km needed to exhume the Metamorphic Core Complexes on shallow angle faults (< 30°) using N-S extension in the Woodlark Basin. High ...
