Mineralogy and seasonal growth of South Pacific mussel valves

Jones, Christie Ann (University of Alabama Libraries, 2010)

Choromytilus chorus and Aulacomya ater are among the most common mussel species in the South Pacific. However, little sclerochronological analysis has been conducted on them, even though they are found in both archaeological ...
The tectonic relationships of the Hillabee Chlorite Schist and the adjacent rock units in southern Cleburne County, Alabama

Hayes-Davis, Bertram (University of Alabama Libraries, 2010)

Southern Cleburne county Alabama contains two defined litho-tectonic blocks separated by a large displacement thrust fault. The Talladega block is composed of low grade metamorphic rocks. Sericite Phyllites and Quartzites ...
Investigation of natural weathering processes and artificial treatment techniques in the attenuation of toxic metals from coal fly ash

Bhattacharyya, Sidhartha (University of Alabama Libraries, 2010)

Coal fly ash contains high levels of hazardous trace elements such as As, B, Cr, Mo, Ni, Se, Sr and V, which may have a negative impact on the environment due to potential leaching by acid rain and groundwater. This study ...
Upper Jurassic (Oxfordian) Smackover facies characterization at Little Cedar Creek Field, Conecuh County, Alabama

Ridgway, John Grayson (University of Alabama Libraries, 2010)

The Upper Jurassic (Oxfordian) Smackover Formation is a shallow-marine carbonate unit in the subsurface of the U.S. Gulf Coast, spanning from south Texas to west Florida. This field case-study focuses on Little Cedar Creek ...
Pore scale study of crude oil distribution and interfacial processes in unconsolidated porous media: an application of synchrotron x-ray microtomography

Ghosh, Jaydeep (University of Alabama Libraries, 2011)

A pore-scale study was conducted to determine model reservoir systems most amenable to oil recovery by investigating the behavior of three fractions of crude oil distribution and morphology in three types of porous media ...
Insights into aragonite diagenesis as evidenced from spelean carbonate

Phillips, Joseph Hunter (University of Alabama Libraries, 2011)

Cave deposits are increasingly being used as paleoclimate archives. Though a majority of cave deposits are composed of calcite, cave deposits composed of aragonite are quite common. Aragonite, being unstable in the cave ...
Recharge estimation and sustainability assessment of groundwater resources in the North China Plain

Cao, Guoliang (University of Alabama Libraries, 2011)

Sustainable use of groundwater resources requires a comprehensive understanding of the groundwater flow system, including recharge mechanisms and system dynamics to quantify future availability and variability of groundwater ...
A comparison of pre-treatment methods for δ^15 N analysis in mollusk shells

Hansen, Jestina Anne (University of Alabama Libraries, 2011)

Two sample preparation methods, acid pretreatment and no pretreatment, for δ^15 N analysis in mollusk shells were compared on sample splits from three common Gulf of Mexico and North Atlantic mollusks (Mercenaria spp., ...
Coseismic and postseismic deformation of the great 2004 Sumatra-Andaman Earthquake

Hughes, Kristin (University of Alabama Libraries, 2011)

The 26 December 2004 M9.2 Sumatra-Andaman earthquake (SAE) induced a devastating tsunami when it ruptured over 1300 km of the boundary between the Indo-Australian plate and Burma microplate (Vigny et al., 2005; Bilek, ...
Rate limited diffusion and dissolution of multi-component non-aqueous phase liquids (NAPLs) in groundwater

Burke, William Randolph (University of Alabama Libraries, 2011)

Contamination of soil and groundwater by nonaqueous phase liquids (NAPLs) poses serious risks to human health and the environment and presents major challenges for cleanup. The presence of complex NAPL mixtures in the ...
The origin and development of the Tampa Embayment: implications for the tectonic evolution of the Eastern Gulf of Mexico

Wilson, Kevin Lance (University of Alabama Libraries, 2011)

Interpreted regional 2D pre-stack depth migrated (PSDM) seismic reflection profiles and restoration of the northern Yucatan and west Florida conjugate rift margins using magnetic anomaly and free-air gravity trends suggest ...
Viento Formation: a syndepositional deltaic system recording adjacent passive salt diapir rise, La Popa basin, northeast Mexico

Platon, Constantin P. (University of Alabama Libraries, 2011)

The Paleocene/Eocene Viento Formation, the youngest shallow marine unit in La Popa mini-basin, Mexico, is exposed adjacent to a surface outcropping salt diapir that is partially welded. Viento Formation offers a rare insight ...
Estimating nonlinear source parameters of volcano deformation: an application of FEM-based inverse methods and InSAR

Stone, Jonathan (University of Alabama Libraries, 2011)

Migration of magma within an active volcano produces a deformation signature at the Earth's surface. The internal structure of a volcano and specific movements of the magma control the actual deformation that is observed. ...
Pressure-temperature-time paths, prograde garnet growth, and protolith of tectonites from a polydeformational, polymetamorphic terrane: Salmon River Suture Zone, West-Central Idaho

McKay, Matthew P. (University of Alabama Libraries, 2011)

The metamorphic rocks of the Salmon River suture zone (SRSZ) in west-central Idaho provide a unique glimpse into mid-lower crustal processes during continental growth by island arc accretion. The SRSZ, which separates ...
Influence of flow regime on U(VI) sorption kinetics in fine sediments at the Hanford site, Washington, USA

Moser, Jessa V. (University of Alabama Libraries, 2012)

The effect of flow rate on U(VI) sorption kinetics was investigated by a series of column tests using the reactive mass fraction (<2mm) of sediments from the 300 Area in Hanford, WA. Three sets of constant flow rates subject ...
Jurassic limestone-marl sequences in northern spain: detecting diagenetic signals using rare earth and trace elements

Hollon, Brittany Elise (University of Alabama Libraries, 2012)

Mesozoic rhythmically bedded limestone and marl sequences have been traditionally interpreted to be the result of eustatic sea-level changes related to Milankovitch cycles. An alternative interpretation supports the idea ...
Experimental simulation of arsenite leaching on soils and mechanism of arsenite oxidation

Yue, Ziming (University of Alabama Libraries, 2012)

Arsenic trioxide was widely applied to soils in North America as an herbicide during the 1950-60s. These herbicide applications led to soil arsenic contamination at numerous sites. Decades after the herbicide application, ...
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 ...
Solubilization of multi-component immiscible liquids in homogeneous systems: a comparison of different flushing agents using a 2-D flow cell

Harvell, Jason Randall (University of Alabama Libraries, 2012)

Complex multi-component immiscible liquid mixtures can significantly limit the effectiveness of groundwater remediation. The use of enhanced-flushing technologies has emerged as a promising technique for the remediation ...
