Stromatoporoids and the Upper Devonian Alamo Impact Breccia of southeastern Nevada

Aul, Jeffrey L. (University of Alabama Libraries, 2010)

Eleven species in 10 genera of stromatoporoids were identified from within and below the Alamo Breccia of southeastern Nevada, in an effort to determine the excavation depth of a bolide impact that occurred during the Late ...
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 ...
Cenozoic landscape evolution of a post-compressional orogenic wedge: intermontane basin development and sediment dispersal patterns, Renova Formation, southwest Montana

Rothfuss, Jennifer L. (University of Alabama Libraries, 2010)

Sediment pathways and landscape evolution are useful proxies for refining the current understanding of crustal and surficial processes that initiated Paleogene post-compressional demise of the Cordilleran orogenic wedge ...
Biostratigraphy, paleogeography, and paleoenvironments of the Upper Cretaceous (Campanian) northern Mississippi Embayment

Ebersole, Sandy (University of Alabama Libraries, 2010)

Most paleogeographic and paleoenvironmental reconstructions of the northern Mississippi Embayment during the Late Campanian (Late Cretaceous) illustrate a generalized gulf between central Mississippi and Arkansas stretching ...
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, ...
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. ...
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 ...
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 ...
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 ...
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., ...
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 ...
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 ...
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 ...
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 ...
U-Pb zircon and monazite geochronology and hafnium isotopic geochemistry of neoacadian and early alleghanian plutonic rocks in the Alabama Eastern Blue Ridge, Southern Appalachian Mountains

Ingram, Stanton B. (University of Alabama Libraries, 2012)

The Alabama eastern Blue Ridge (EBR) of the Southern Appalachian Mountains hosts a variety of felsic plutonic rocks, which intrude multiply deformed Neoproterozoic to Ordovician metasedimentary rocks. Plutons consist of ...
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 ...
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 ...
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 ...
