Hydrogeology Of The Little River Animal Agriculture Environmental Research Unit And Impacts Of Dairy Operations On Groundwater, Robert Wesley Hunter
Hydrogeology Of The Little River Animal Agriculture Environmental Research Unit And Impacts Of Dairy Operations On Groundwater, Robert Wesley Hunter
Masters Theses
This thesis describes the development of an integrated hydrogeologic/hydrologic site assessment and groundwater/surface water quality monitoring program at the University of Tennessee – Little River Dairy Farm, located near Townsend, TN. Hydrologic/hydrogeologic investigations of streams and groundwater at the site have been underway for more than 5 years, and these are expected to provide background data for assessing impacts of dairy wastes. The lower half of the ~180 ha site consists of low-relief fields used for row crops, which are underlain by 4 – 9 m of alluvial deposits on top of black shale or limestone that include sinkhole features. …
Detailed Geologic Studies Of Paleoseismic Features Exposed At Sites In The East Tennessee Seismic Zone: Evidence For Large, Prehistoric Earthquakes, Kathleen Frances Warrell
Detailed Geologic Studies Of Paleoseismic Features Exposed At Sites In The East Tennessee Seismic Zone: Evidence For Large, Prehistoric Earthquakes, Kathleen Frances Warrell
Masters Theses
The East Tennessee seismic zone (ETSZ) is the second most active in the eastern United States, but recorded earthquakes do not exceed Mw [moment magnitude] = 4.6. Earthquake epicenters are located 5-26 kilometers deep in autochthonous basement, and faults producing these earthquakes do not break the surface. Detailed paleoseismic investigations at sites within the ETSZ include: detailed geological mapping, trenching, aerial photograph reconnaissance, X-ray diffraction (XRD), grain-size analysis, and optically stimulated luminescence dating of alluvium.
Site DL-6 near Dandridge, Tennessee, reveals a complex array of features providing evidence that at least 4‒6 Mw > 6 earthquakes affected the area. …
The Geology Of The South Antelope Pass Area Of The Southern Peloncillo Mountains, Hidalgo County, New Mexico, John A. Yellich
The Geology Of The South Antelope Pass Area Of The Southern Peloncillo Mountains, Hidalgo County, New Mexico, John A. Yellich
Masters Theses
Volcanic activity during the middle and late Tertiary has been recorded in the mountain ranges of the southwestern United States and northern Mexico and the two provinces of prominent volcanic activity, the Sierra Madre Occidental and the Mogollon Plateau, dominantly rhyolitic in composition, are connected by the Peloncillo Range. The predominant rock chemistry of the south Antelope Pass area is “rhyolitic”; however, lava rock types dominate over welded tuff rock types of the two provinces. There is a limited pre-Tertiary rock record of limestones and sandstones in the northeastern part of the study area. The rest of the study area …
Metamorphic Phase Equilibria In A Contact Aureole: Tres Hermanas Mountains, Luna County, New Mexico., Carissa Dawn Snyder
Metamorphic Phase Equilibria In A Contact Aureole: Tres Hermanas Mountains, Luna County, New Mexico., Carissa Dawn Snyder
Masters Theses
To characterize the metamorphism in the Tres Hermanas Mountains contact–metamorphic aureole in Luna County, New Mexico, I mapped and collected samples of the Paleozoic strata near the quartz monzonite pluton along the northeast flank of North Peak. Stratigraphy in this area includes the Pennsylvanian undivided unit that is composed of thin-medium interbedded limestone, shale, and sandstone and the Hueco Formation that could be broken out into four members: a pebble–cobble conglomerate marks the base, a medium to massive bedded siliceous limestone is next, followed by a pure limestone member and topped by a breccia bed in places marking the fault …
Emplacement Mechanisms And Magma Driving Pressure Of The Proterozoic Curecanti Pluton; The Black Canyon Of The Gunnison, Colorado, Gordon Leonard Hicks
Emplacement Mechanisms And Magma Driving Pressure Of The Proterozoic Curecanti Pluton; The Black Canyon Of The Gunnison, Colorado, Gordon Leonard Hicks
Masters Theses
There is significant obliquity between the margins of the Curecanti pluton, an internal foliation, a coeval swarm of ~400 pegmatite dikes just west of the pluton, and the host rock foliation. This pluton is a 5 km-long, 3 km-wide, and 0.4 km-thick sheet of monzogranite exposed in the Black Canyon of the Gunnison, CO. The pluton is discordant along most of its length, but has a >100-m-thick root at its western margin subparallel to the foliation in the host rock gneisses. A cordierite + anthophyllite + staurolite + garnet schist from the Vernal Mesa pluton aureole was previously dated (1.4 …
Quantifying The Relationship Among Ground Penetrating Radar Reflection Amplitudes, Horizontal Sub-Wavelength Bedrock Fracture Geometries, And Fluid Conductivities, Carolyn Morgan Tewksbury-Christle
Quantifying The Relationship Among Ground Penetrating Radar Reflection Amplitudes, Horizontal Sub-Wavelength Bedrock Fracture Geometries, And Fluid Conductivities, Carolyn Morgan Tewksbury-Christle
Masters Theses
Accurate characterization of subsurface fractures is indispensible for contaminant transport and fresh water resource modeling because discharge is cubically related to the fracture aperture; thus, minor errors in aperture estimates may yield major errors in a modeled hydrologic response. Ground penetrating radar (GPR) has been successfully used to noninvasively estimate fracture aperture for sub-horizontal fractures at outcrop scale, but limits on vertical and horizontal resolution are a concern. Theoretical formulations and field tests have demonstrated increased GPR amplitude response with the addition of a saline tracer in a sub-millimeter fracture; however, robust verification of existing theoretical equations without an accurate …
Metamorphism, Kinematic Evolution, And Timing Constraints Of The Greenbrier Fault Around The Ela And Bryson City Domes, North Carolina, Remington M. Leger
Metamorphism, Kinematic Evolution, And Timing Constraints Of The Greenbrier Fault Around The Ela And Bryson City Domes, North Carolina, Remington M. Leger
Masters Theses
Field mapping, microstructural analysis, and electron microprobe analysis were performed on rocks from the Bryson City and Ela domes, North Carolina, to help constrain the tectonic history of the region. The domes are en echelon northeast-trending antiformal structures formed by two perpendicular sets of folds. They are bounded by the Greenbrier fault, which forms a ductile shear zone that juxtaposes the Great Smoky Group in the hanging wall with Grenville basement in the footwall. Isoclinal folds (F2) and axial planar foliation (S2) characterize the regional deformation (D2). Inter- to syn-kinematic porphyroblasts (relative to D2) of kyanite, staurolite, and garnet grew …
Integrating Depositional Facies And Sequence Stratigraphy In Characterizing Unconventional Reservoirs: Eagle Ford Shale, South Texas, Seth Jordan Workman
Integrating Depositional Facies And Sequence Stratigraphy In Characterizing Unconventional Reservoirs: Eagle Ford Shale, South Texas, Seth Jordan Workman
Masters Theses
The Mid-to-Late Cretaceous Eagle Ford Shale of South Texas is a mixed siliciclastic/carbonate, unconventional resource play with considerable oil and natural gas. Characterization of Eagle Ford reservoir quality and potential is made difficult by complex, small-scale heterogeneities.
The limited availability of subsurface data constrains previous subsurface Eagle Ford investigations. As a result, the internal variability of depositional facies and reservoir attributes remain poorly understood for these Eagle Ford rocks.
This investigation incorporates a representative group of four Eagle Ford cores, and core data, from within the current play area in order to: 1) determine facies successions, 2) establish a hierarchal …
Analysis Of Depositional Facies And Geological Controls On Reservoir Quality In Lower-Middle Devonian Sylvania Sandstone, Midland County, Michigan, Katherine A. Pollard
Analysis Of Depositional Facies And Geological Controls On Reservoir Quality In Lower-Middle Devonian Sylvania Sandstone, Midland County, Michigan, Katherine A. Pollard
Masters Theses
The early-Middle Devonian Sylvania “Sandstone” is considered a target for potential CO2 geosequestration. In order to develop geostatic models for CO2 injection simulations, controls on reservoir properties must be addressed. The three objectives of this study involve: 1) develop an overview of depositional lithofacies and their vertical stacking relationships, 2) determine fluid sources and controls of diagenesis (dolomitization and silicification), and 3) examine geological controls on the distribution and character of reservoir facies.
The grossly transgressive Sylvania-Bois Blanc interval is a complex lithologic assemblage. Sylvania “Sandstone” strata transition from high energy, subtidal to lower-intertidal mixed carbonate-siliciclastic facies to …
Late Mississippian (Chesterian) Through Early Pennsylvanian (Atokan) Strata, Michigan Basin, U.S.A., Shannon M. Towne
Late Mississippian (Chesterian) Through Early Pennsylvanian (Atokan) Strata, Michigan Basin, U.S.A., Shannon M. Towne
Masters Theses
Over 2,000 linear feet of core material was analyzed to evaluate the stratigraphy and basin evolution of Carboniferous strata in the Michigan basin. Rock units were evaluated on the basis of lithofacies type, contact relationships, and existing regional geologic interpretations. The recovery of three distinct pollen and spore assemblages from core confirms the timing of deposition during the Late Mississippian Chesterian and Early-Middle Pennsylvanian Morrowan and Atokan regional stages within the Michigan basin.
The deposition of a marine carbonate succession with significant interstratified quartz sandstone occurred during the Chesterian regional stage. The Bayport interval (Bayport Limestone) is composed of seven …

A Structural Analysis Of The El Kasr Structure In The Western Desert Of Egypt, Trevor Charles Ellis
A Structural Analysis Of The El Kasr Structure In The Western Desert Of Egypt, Trevor Charles Ellis
Masters Theses
"The El Kasr structure was studied in order to investigate the origins and evolution of the enigmatic Desert Eyes structures of the Western Desert due to its accessibility and uniqueness among the structures. The El Kasr structure, an elongate structural basin with low limb dips, is unique among the "Desert Eyes" structures in that it: 1) occurs in isolation in otherwise horizontal sedimentary rock, 2) the long dimension of the basin is oriented NNW, 3) it is closely spatially associated with the less common NNW fault zones, and 4) is composite in nature. The structure was investigated using remote sensing …
