Whole-Rock Lead-Lead Systematics And Major Element Analyses On The 1.85 Ga. Flin Flon Paleosol, Manitoba, Canada: Implications For Uranium Mobility., Federico Arturo Valencia
Geosciences Theses
The 1.85 Ga Flin Flon paleosol located in Flin Flon, Manitoba, Canada, is studied with the purpose of determining the timing and geochemical trend of uranium migration. Radiometric minimum ages of sediments and paleosols indicates the presence of a post-depositional event, these ages are bracketed by the Trans-Hudson orogeny event (2155–1750 Ma) which resulted in the alteration of κ(Th/U) and µ(U/Pb) ratios by exposing volcanics to the atmosphere and instigating the mobilization of U. The profile shows that the Missi sediments lost Uby 84% average relative to corrected average upper crust value. The upper paleosol gained U by 11% and …
A Geochemical Analysis: Application Of A Chelating Agent On Potential Asr Reactive Aggregates, Jennifer N. Garcia
A Geochemical Analysis: Application Of A Chelating Agent On Potential Asr Reactive Aggregates, Jennifer N. Garcia
Geosciences Theses
Alkali Silica Reaction (ASR) is a deleterious, expansive reaction in concrete. Several ASTM methods test potential aggregates for ASR risk. One method uses NaOH digestion, followed by spectroscopic methods, to estimate the amount of reactive silica present in an aggregate. NaOH, however, can digest both crystalline (i.e. quartz) and non-crystalline (e.g. opal), or poorly crystalline silica, potentially yielding falsely high estimates of reactive silica. Studies in soil and plant sciences have used Tiron, an alkaline chelating agent (C6H4S2O8Na2), as a method of digesting opaline silica for spectroscopic analysis. Here we …

Assessment Of Watershed Model Simplification And Potential Application In Small Ungaged Watersheds: A Case Study Of Big Creek, Atlanta, Ga, Zoia A. Comarova Ms
Geosciences Theses
Technological and methodological advances of the past few decades have provided hydrologists with advanced and increasingly complex hydrological models. These models improve our ability to simulate hydrological systems, but they also require a lot of detailed input data and, therefore, have a limited applicability in locations with poor data availability. From a case study of Big Creek watershed, a 186.4 km2 urbanizing watershed in Atlanta, GA, for which continuous flow data are available since 1960, this project investigates the relationship between model complexity, data availability and predictive performance in order to provide reliability factors for the use of reduced …
Stakeholders' Perceptions Of Risk For Gentrification In Atlanta's Pittsburgh Neighborhood, David C. Holmes
Stakeholders' Perceptions Of Risk For Gentrification In Atlanta's Pittsburgh Neighborhood, David C. Holmes
Geosciences Theses
The 2008-2010 foreclosure crisis and the Beltline project present two significant forces shaping neighborhoods throughout Atlanta. Both the high foreclosure rates and the promise of public and private investment create conditions for the displacement of existing residents and for the gentrification of the southwest Atlanta neighborhood of Pittsburgh in particular. Through qualitative analysis, including interviews with residents, community leaders, and government officials, the development of overlay analysis maps of Pittsburgh, as well as studying the various stakeholders' perception of risk for gentrification in Pittsburgh, this research examines how and why these stakeholders' perception of the risk of gentrification in Pittsburgh …
Critical Thresholds For Sediment Mobility In An Urban Stream, Ross H. Martin
Critical Thresholds For Sediment Mobility In An Urban Stream, Ross H. Martin
Geosciences Theses
Bed load transport measurements were made in a small urban stream in Decatur, GA, from which thresholds for motion were calculated using methodologies from the published literature. These methodologies are discussed in terms of their limitations and assumptions. Mobility frequencies were calculated for single grains of each grain size fraction to illustrate the transition from size selective transport to equal mobility. In general, urban streams behave differently than many gravel rivers in non-urban settings because of differences in the availability and character of sediment sources and altered flow hydrographs. This comparison allows for discussion about the way sediment is transported …
Spatiotemporal Analyses Of Child Pedestrian-Vehicle Incidents Occurring During School-Commuting Hours In Metro Atlanta From 2000 To 2007, Amy M. Moore
Geosciences Theses
From 2000 to 2007, the five core county area of Metropolitan Atlanta (Fulton, Dekalb, Clayton, Cobb and Gwinnett) experienced 1,871 incidents involving child pedestrians. Nearly one-third of these incidents occurred during school-commuting hours. This study examines the geospatial locations of these incidents, with regards to the location of all 647 public schools within the study area. A GIS is used to analyze the spatiotemporal arrangement of these incidents in order to find risk factors and patterns in the data. Aspects of the built environment are then considered in areas with higher frequencies of child pedestrian-vehicle incidents. A walkability assessment is …
Particle Size, Critical Shear Stress, And Benthic Invertebrate Distribution And Abundance In A Gravel-Bed River Of The Southern Appalachians, Helen Mayoral
Geosciences Theses
To determine the relationship between the abundance and density of benthic invertebrates, and the critical shear stress of individual grain sizes, a reach along Smith Creek, was divided into ten 2m x 2m quadrants. Within each quadrant, five randomly selected clasts for each grain size ranging from 2.26 to 25.6 cm were cleaned for benthic invertebrates. Wolman pebble counts for each quadrant were also conducted and used to determine the critical Shields stress per grain size fraction from the model given by Wiberg and Smith (1987) that explicitly accounts for particle hiding/sheltering effects in mixed-bed rivers. Particle entrainment values were …
Mineralogy And Geochemistry Of The Bauxite Deposits (Cretaceous), Wilkinson County, Georgia., Adebayo O. Ayorinde
Mineralogy And Geochemistry Of The Bauxite Deposits (Cretaceous), Wilkinson County, Georgia., Adebayo O. Ayorinde
Geosciences Theses
Cretaceous bauxite deposits from Hall and Veneer mines, Wilkinson County, Georgia are composed of kaolinite, gibbsite, goethite, anatase, nordstrandite and bohemite. Quartz and micas are absent in the samples. The presence of boehmite and goethite are evidence of intense weathering forming the bauxite deposits. The extremely high values of the Chemical Index of Alteration (CIA) which is over 99, and the low values of the alkali metals and alkali earth metals, support an intense weathering origin for the bauxite deposit. There is evidence of deposition in the mines based on the presence of pisoids in the bauxite samples and the …
Intensive Study Of Ambient Carbon Dioxide Variability In Urban Atlanta, Brian L. Vann Mr.
Intensive Study Of Ambient Carbon Dioxide Variability In Urban Atlanta, Brian L. Vann Mr.
Geosciences Theses
Urban areas contain multiple sources and sinks of carbon dioxide, yet spatial and temporal information explaining its variability, diurnal patterns, and effects from human activity are limited. The city of Atlanta, due to conflicting air masses, geographic location, and population growth, is as an excellent location to study carbon dioxide concentrations across its urban landscape. Mobile measurements of ambient CO2 concentrations were obtained at 1.5m above ground level along a transect in winter 2010 within the perimeter of Atlanta. Analyses of winter 2010 CO2 variability at GSU’s stationary CO2 monitor was also explored. The results showed that …
Labor Agency Beyond The Union: The Coalition Of Immokalee Workers And Faith-Based Community Organizations, Michael Husebo
Labor Agency Beyond The Union: The Coalition Of Immokalee Workers And Faith-Based Community Organizations, Michael Husebo
Geosciences Theses
Labor geographers have identified multiple strategies through which workers assert their demands in an era of global production networks. In this thesis I examine the strategic organizational actions of the Coalition of Immokalee Workers (CIW), a community-based organization representing immigrant farm-workers in southwestern Florida. Central to the successes of the CIW is its strategy to organize and embed its agency in civil society. Social actors have proved to be of vital importance as they enabled the CIW to position itself strategically in important locations of the production network to contest capitalist geographies more effectively. Using qualitative analysis of in-depth interviews …

The Effects Of High Density Septic Systems On Surface Water Quality In Gwinnett County, Georgia, John R. Anderson Ii
Geosciences Theses
Gwinnett County, Georgia experienced rapid growth in the 1970’s without the infrastructure so septic systems were installed for residential homes. The number of septic systems grew to over 85,000 with a density of 487 septic systems per square mile. This study mapped the distribution of septic systems to determine regions of potential pathogen surface water. This study addressed what potential health risks do high density septic systems have on surface water quality and how can the history of Gwinnett County assist in future development in the Metropolitan Atlanta area? It was found that the density of septic systems has reduced …
K-Ar Age Values Of Bulk Soil Samples And Clay Fractions: Effects Of Acid Extraction And Implications For The Origin Of Micaceous Clay In Savannah River Site Soils, South Carolina, Usa, Thomas E. Naumann
Geosciences Theses
Understanding how natural Cs, Rb, and K have been redistributed in Savannah River Site (SRS) soils during pedogenesis is important to understanding how radiocesium released to the soils will behave over the long term. In this effort, it is important to distinguish K that has participated in mineral-water reactions from that still residing in primary silicate structures, particularly in the clay fraction. The impact of different degrees of acid extraction on K and radiogenic Ar in bulk soil and in clay from five SRS soil samples has been determined. Strong treatment (50% HNO3, three hours, 100°C) releases K from primary …
Mineralogical And Geochemical Indicators Of Subaerial Weathering In The Pozzolane Rosse Ignimbrite (Alban Hills Volcanic District, Italy), Jennifer M. Dickie
Mineralogical And Geochemical Indicators Of Subaerial Weathering In The Pozzolane Rosse Ignimbrite (Alban Hills Volcanic District, Italy), Jennifer M. Dickie
Geosciences Theses
The Pozzolane Rosse ignimbrite [PR] (457±4 ka) in the Alban Hills Volcanic District, Rome, Italy was exposed ~ 40 ka prior to a subsequent volcanic event which coverd it entirely. XRF, XRD, and clay separation results from PR samples from INGV and CA1 boreholes and Castel di Leva quarry show evidence of paleopedogenesis. All locations display loss of base cations, loss of K is consistent with XRD datat showing dissolution or alteration of leucite to analcime. Accumulation of Al and high L.O.I. support XRD evidence of 1:1 clay species at upper depth. Data suggest alteration extent can be determined by …

Analyses of samples collected per EISOPQAM guidelines include the following: petrographic, conductivity, pH, XRD, XRF, TDS, and major cations and anions. Preliminary field pH and conductivity measurements indicate that waters near the slag pile have a pH ranging from 11-12 and a conductivity ranging from 1115-6300 μS/ cm. Titration data indicate that the maximum pH value is 12.5. These calcite stalactites and stream coatings result from the dissolution …
Evaluating The Effects Of Green Roofs As Tools For Stormwater Management In An Urban Metropolis, Robyn R. Polinsky
Evaluating The Effects Of Green Roofs As Tools For Stormwater Management In An Urban Metropolis, Robyn R. Polinsky
Geosciences Theses
Stormwater management is an essential aspect of urban hydrology. Urbanized areas have large amounts of impervious surface cover (ISC) and well developed sewer and drainage networks which rapidly channel water and pollutants off of streets and into local streams. This research evaluates the use of vegetated roofs as mechanisms to reduce ISC and stormwater runoff in downtown Atlanta. A 3-D model of the study site was created so that runoff rates could be measured for various rooftop scenarios under different size storm events. The results revealed a reduction in peak runoff and an increase in both the lag time and …
Analysis Of Channel Networks And The Potential For Sediment Transport In The Vicinity Of The North Polar Seas Of Titan, Richard Cartwright
Analysis Of Channel Networks And The Potential For Sediment Transport In The Vicinity Of The North Polar Seas Of Titan, Richard Cartwright
Geosciences Theses
This study analyzes the available radar evidence in order to describe the morphology of channel networks around the north polar seas of Titan. Critical flow depths necessary to entrain water-ice grains, and denudation rates for a north polar channel network are discussed. The results indicate that channel networks on Titan have similar morphologies to channel networks cut by water on Earth. We also find that water-ice sediment should be readily entrained in the headwaters and downstream sections of the analyzed Titanian basin, given sufficient flow depths of liquid hydrocarbons. Also, the importance of slope and the elevated topography of the …
Magmatic Evolution Of The Eocene Volcanic Rocks Of The Bijgerd Kuh E Kharchin Area, Uromieh-Dokhtar Zone, Iran, Armita Davarpanah
Magmatic Evolution Of The Eocene Volcanic Rocks Of The Bijgerd Kuh E Kharchin Area, Uromieh-Dokhtar Zone, Iran, Armita Davarpanah
Geosciences Theses
Composition and texture of the Middle and Late Eocene volcanic, volcaniclastic, and volcanic-sedimentary rocks in the Bijgerd-Kuh e Kharchin area, in the Uromieh-Dokhtar zone northwest of Saveh, Iran, suggest the complexity of the magmatic system that involved multiple eruptions from one or more sources. Hydrated volcanic fragments in hyaloclastic rocks, and the presence of a sequence of shallow and intermediate-depth marine microfossils, suggest that the Middle Eocene units were erupted in a marine basin. The bimodal volcanism of the Late Eocene is distinguished by the presence of four alternating sequences of hyaloclastite lava and ignimbrite. The REE patterns show spatial …

The fluctuations in solute concentrations from eight springs in the Ridge and Valley Province in northwestern Georgia were used to determine flow types and to measure each aquifer’s ability to remove contamination. The target springs are located along a northeast trending line in the Ridge and Valley Province of northwest Georgia. This study determined and interpreted the fluctuations in chemistry of each of the sampled spring’s water based upon temporal variations of precipitation in the area and variations in the chemistries measured at each weekly sampling event. Analysis determined that carbonate springs that showed characteristics of diffuse flow, including stable …
Race, Place, And Identity: Examining Place Identity In The Racialized Landscape Of Buckhead, Atlanta, Robert Edward Cochran
Race, Place, And Identity: Examining Place Identity In The Racialized Landscape Of Buckhead, Atlanta, Robert Edward Cochran
Geosciences Theses
This thesis examines the role of racialized practices in the discourses and processes that alter place identity. Drawing on ethnography from the East Village of Buckhead, a once vibrant nightlife district in Atlanta, I examine how discourses of danger, colorblindness, and the race card have been employed to “whitewash” the discussions about the redevelopment of the Village. In effect, the business and civic elite of Atlanta (and Buckhead) deployed racialized conceptualizations of group identity. In particular, they utilized “public safety” discourses to influence the Atlanta city government to support the redevelopment effort. This led to the elimination of the establishments …

The exploration of immigrants’ experiences in various spaces includes public and semi-public, employment, educational and organizational spaces. Interviews were conducted on 24 female immigrants in the Atlanta area who possess various backgrounds. While female immigrants who wear the hijab experienced more, and more direct, discrimination than those who wear Western styles, the women who wear hijab were not …
Clay Mineralogy And Illite Crystallinity In The Late Devonian To Early Mississippian Woodford Shale In The Arbuckle Mountains, Oklahoma, Usa, Richard Allen Whittington Ii
Clay Mineralogy And Illite Crystallinity In The Late Devonian To Early Mississippian Woodford Shale In The Arbuckle Mountains, Oklahoma, Usa, Richard Allen Whittington Ii
Geosciences Theses
Commonly the thermal maturity of the Late Devonian to Early Mississippian Woodford shale found on the flanks of the Arbuckle Mountains of Oklahoma is determined by vitrinite reflectance, values ranging from 0.3-1.5%. Using phyllosilicate minerals, specifically diagenetic mixed layer illite/smectite and diagenetic illite, an understanding of the extent and processes leading to the thermal maturation may be developed. Analysis by XRD of the clay mineralogy of the Woodford shale found kaolinite and mixed layer illite/smectite with <5% smectite and R≥3 stacking order. Modeling of the Woodford shale also suggests the percentage of smectite present in mixed layer illite/smectite to be <5% and commonly <2.5%. Deconvolution of the illite (001) peak supports the low smectite content and high illite crystallinity. The long range ordered illite, R≥3, and high illite crystallinity values are indicative of diagenesis to anchizone conditions suggesting a higher thermal maturity relative to previously measured values of vitrinite reflectance.
Improving Summer Drought Prediction In The Apalachicola-Chattahoochee- Flint River Basin With Empirical Downscaling, John Robert Dean
Improving Summer Drought Prediction In The Apalachicola-Chattahoochee- Flint River Basin With Empirical Downscaling, John Robert Dean
Geosciences Theses
The Georgia General Assembly, like many states, has enacted pre-defined, comprehensive, drought-mitigation apparatus, but they need rainfall outlooks. Global circulation models (GCMs) provide rainfall outlooks, but they are too spatially course for jurisdictional impact assessment. To wed these efforts, spatially averaged, time-smoothed, daily precipitation observations from the National Weather Service cooperative network are fitted to eight points of 700 mbar atmospheric data from the NCEP/NCAR Reanalysis Project for climate downscaling and drought prediction in the Apalachicola-Chattahoochee-Flint (ACF) river basin. The domain is regionalized with a factor analysis to create specialized models. All models complied well with mathematical assumptions, though the …
A Comparative Study Of The Badger Pass Igneous Intrusion And The Foreland Volcanic Rocks Of The Mcdowell Springs Area, Beaverhead County, Montana: Implications For The Local Late Cretaceous Sequence Of Events, Brookie Jean Gallagher
A Comparative Study Of The Badger Pass Igneous Intrusion And The Foreland Volcanic Rocks Of The Mcdowell Springs Area, Beaverhead County, Montana: Implications For The Local Late Cretaceous Sequence Of Events, Brookie Jean Gallagher
Geosciences Theses
Intermediate igneous rocks exposed in the Badger Pass area and 3.5 km away in the McDowell Springs area of Beaverhead County, Montana, previously mapped as Cretaceous intrusive (Ki), and Cretaceous undifferentiated volcanics (Kvu) respectively, exhibit little geochemical variation. Trace element, and lead isotope analyses provide strong evidence allowing for a single source. REE patterns, obtained through ID-ICP-MS, are essentially identical. Mineral/melt Eu analyses reveal that Eu behaved predominantly as a divalent cation, refuting an earlier study asserting that trivalent Eu dominated. Data suggest rocks were formed under low oxygen activity conditions, not oxidizing conditions as previously reported. Geochemical data combined …

A Multitemporal Analysis Of Georgia's Coastal Vegetation, 1990-2005, Charles, Iii F. Breeden
Geosciences Theses
Land and vegetation changes are part of the continuous and dynamic cycle of earth system variation. This research examines vegetation changes in the 21-county eco-region along coastal Georgia. The Advanced Very High Resolution Radiometer (AVHRR) with Normalized Difference Vegetation Index (NDVI) data is used in tandem with a Principal Component Analysis (PCA) and climatic variables to determine where, and to what extent vegetation and land cover change is occurring. This research is designed around a 16 year time-series from 1990-2005. Findings were that mean NDVI values were either steady or slightly improved, and that PC1 (Healthiness) and PC2 (Time-Change) explained …
Remote Sensing And Gis Analysis Of Spatial Distribution Of Fracture Patterns In The Makran Accretionary Prism, Southeast Iran, Shankar Babu Pokharel
Remote Sensing And Gis Analysis Of Spatial Distribution Of Fracture Patterns In The Makran Accretionary Prism, Southeast Iran, Shankar Babu Pokharel
Geosciences Theses
This study shows that remote sensing and GIS are powerful tools in identifying geologically induced lineaments from digitally enhanced ETM+ satellite imageries and the digital elevation model (DEM) in remote areas such as the Makran accretionary prism, southeast Iran. The presence of the conjugate shear fractures in the eastern part, along with the extensional, and the presence of reidal sets associated with the subsidiary fractures of the Minab-Zendal fault system in the western part, suggests that the structural pattern changes from pure shear to simple shear from east to the west across the prism. Moreover, the gradual increase in the …

Comparative Baseflow Hydrochemistry Of Various Septic System Density Groups Within The Yellow River Watershed, Gwinnett County, Georgia, Robert Carl Neurath
Geosciences Theses
Baseflow water chemistry between different septic system density groups was analyzed to understand how septic system usage impacts the water quality of the Yellow River Watershed located in Gwinnett County, Georgia. Seventy water samples were collected at baseflow conditions in the summer of 2006. The samples were analyzed for the abundance and distribution of chlorides, sulfates, nitrates, and specific conductance. Geographic Information Systems were used to determine sample collection sites, assign samples into density groups, and spatially analyze and display the results. Statistical methods were used to compare the results of each density group with all others,and to find any …
Spatial Analysis Of Substantiated Child Maltreatment In Metro Atlanta, Georgia, Yueqin Zhou
Spatial Analysis Of Substantiated Child Maltreatment In Metro Atlanta, Georgia, Yueqin Zhou
Geosciences Theses
Identifying high-risk areas for child maltreatment to ultimately aid public health agencies for interventions is necessary for protecting children at high risk. Rates of substantiated neglect and physical/emotional abuse in 2000-2002 are computed for the census tracts in the urban area of five counties in Metro Atlanta, Georgia, and analyzed using spatial regression to determine their relationships with twelve risk variables computed from the Vital Records births and the 2000 Census data. After accounting for multicollinearity among risk variables and spatial autocorrelation among observations for neighboring locations, it is found that high percentages of (1) births to non-married mothers, (2) …
