Seismic Stratigraphic Analysis Of The Upper Indus-Fan Complex A Model For Fan Development, Syed Firasat Shah

OES Theses and Dissertations

The seismic stratigraphic analysis of the upper Indus-Fan Complex has revealed the presence of six depositional sequences. Deposition of these sequences occurred primarily during the Miocene period. The Indus River drainage system that developed as a consequence of Himalayan orogeny transported the bulk of the sediments deposited in the Indus Fan. The distribution and thickness of the sequences of the upper Indus Fan are closely related to the canyon-channel systems. Seismic facies analysis of the slope has revealed the presence of a facies relationship that shows continued deepening from the time of deposition of slope fan to the latest deposits …

Land Management Report For The Kent River Catchment, Sue Kelly

Natural resources published reports

The Kent River Catchment is located in the South-West of Western Australia, approximately between latitudes 34° 15' and 35° 10' South and longitudes 116° 45" and 117° 50° East. The north-eastern boundary of the catchment stretches to the Albany Highway at Tenterden, and from there the catchment curves towards Rocky Gully before continuing to the South Coast (Figure 1.1.1). The catchment is located within the Shires of Cranbrook, Plantagenet and Denmark.

The Kent River Catchment is part of Basin 604, which is the Water Authority descriptor for the Kent, Bow and Kordabup River catchments collectively. Basin 604 has a total …

Depositional History, Environments Of Deposition, And Hydrocarbon Potential Of The Newcastle Formation (Lower Cretaceous) Of Eastern North Dakota, Gerald G. Mccloskey

Theses and Dissertations

The Newcastle Formation (Albian) in North Dakota is composed primarily of fine grained sandstone, mudstone and shale. This study examined the Newcastle within the eastern two thirds of North Dakota, with the goal of determining the various depositional environments, the depositional history, and the hydrocarbon potential of the unit. A total of 2191 geophysical well logs and 21 lithologic cores were examined. Isopach maps of the Newcastle Formation and the Skull Creek Shale were generated, as was a structural top map of the Mowry Shale.

The depositional history of the unit is directly linked to the regression and subsequent transgression …

The Paleoecologic Significance Of Paleocene Palynomorph Assemblages From The Ludow, Slope, And Cannonball Formations, Southwestern North Dakota, Timothy J. Kroeger

Theses and Dissertations

Paleoenvironment exerted control on the distribution of 133 palynomorph taxa from the Ludlow and Slope Formations and Boyce and Three V Tongues of the Cannonball Formation (Fort Union Group, I Paleocene) of southwestern North Dakota. The strata represent fluvial deltaic systems that prograded eastward into the Cannonball Sea. Depositional environments include distributary channels, crevasse splays, crevasse-splay feeder channels, lignite-producing swamps and/or marshes, lakes, brackish to slightly brackish bays, lake and bay fills, and marshes

Paleoenvironmentally sensitive palynomorph taxa were identified by subjective examination of pollen diagrams and objective analysis using detrended correspondence analysis. Two paleoenvironmentally restricted palynomorph associations were recognized. …

Prey Selectivity By Naticid Gastropods From Tertiary Sediments Of The United States Coastal Plain, Robert N. Sickler

Theses and Dissertations

Previous studies have shown that naticid gastropod predators are highly selective of prey species in accordance with the Kitchell et al. (1981) cost-benefit model. In addition, earlier studies have demonstrated selectivity of drillhole siting and intraspecific prey size. This study focuses on prey selectivity by Oligocene naticid gastropods and is used to test Vermeij's (1987) hypothesis of escalation. The hypothesis of escalation states that biologic hazards have increased during the Phanerozoic and that organisms have either had to adapt to these hazards or face possible extinction (Vermeij, 1987). Naticid predation on molluscan assemblages is one of several examples used to …

Salinity, Radon, And Radon Precursors In The Soils Of Grand Forks County, North Dakota, Kevin L. Solie

Theses and Dissertations

High levels of indoor radon have been observed in many areas of the Red River Valley and particularly in Grand Forks County of North Dakota. Data from the University of North Dakota (UND) Radon Monitoring Facility indicated more than 80% of the dwellings tested had radon levels greater than the United States Environmental Protection Agency (USEPA) action limit of 4 pCi/l. High radon levels may pose a health threat (USEPA, 1986) to valley residents.

A review of existing data indicates that areas of the Red River Valley in North Dakota with elevated soil salinity also exhibit higher equivalent uranium (eU) …

Depositional Environments And Paleogeography Of The Winnipeg Group (Ordovician), Williston Basin, North Dakota, Jonathan B. Ellingson

Theses and Dissertations

The Winnipeg Group (Upper Ordovician) unconformably overlies the Deadwood Formation (Cambrian - Lower Ordovician) over most of North Dakota, except in the extreme eastern part, where it lies directly on Precambrian basement rocks. The Winnipeg is conformably overlain by the Red River Formation (Upper Ordovician). The Winnipeg reaches a maximum thickness of 448 feet (136.6 m) in the center of the basin, Williams County. The Winnipeg Group consists of three formations, in ascending order, the Black Island, Icebox, and Roughlock Formations. The Black Island Formation is, herein, formally divided into the Hawkeye Valley and the Garland Members.

The Hawkeye Valley …

Geological And Hydrogeological Characterization Of The Schoolcraft Aquifer, Schoolcraft, Michigan, William K. Steinmann

Masters Theses

Newly installed monitoring wells, county well logs, gamma-ray logs, head measurements, flow nets, slug tests, and full aquifer pumping tests were utilized to characterize the geologic and hydrogeologic conditions of the area. Evaluation of the geologic conditions indicate that the study area is best described as a glacially generated, humid type, alluvial fan. A hydrogeologic facies model concept aided in the initial evaluation of the hydrogeologic conditions and was utilized for the placement of several vertically nested monitoring wells. Further evaluation indicates an unconfined aquifer comprised of two separate flow systems: a shallow, local flow system interacting with flow-through surface …

Do Microplates In Subduction Zones Leave A Geological Record?, Jeffrey Lee, Joann M. Stock

All Faculty Scholarship for the College of the Sciences

Active microplate boundaries in ocean-continent subduction zones may induce deformation of the overlying plate and spatial or geochemical variations in the volcanic arc. We discuss two modern cases. The first is the South Gorda-Juan de Fuca plate boundary in the Cascadia subduction zone, where there is little or no effect on the overriding plate and the oceanic plate takes up much of the deformation. The second case is the Cocos-Rivera plate boundary in the Middle America trench, where the overlying Colima graben contains substantial deformation in a zone extending from the trench to the volcanic arc and the sub-duction-related volcanism …

An Evaluation Of Five Perfluorinated Hydrocarbons As Tracers In Non-Aqueous Phase Liquids, Jennifer K. Bergin

Masters Theses

Tracers are used in many facets of hydrogeological investigations. At this time, only tracers for aqueous phase liquids are known. The object of this investigation is to assess the viability of a suite of hydrocarbons as tracers m underground spills of non-aqueous phase liquids.

Laboratory experiments were performed to determine if the potential tracers were soluble in common petroleum hydrocarbons, non-volatile, differentiable and quantifiable by GC/MS, and conservative.

The first compound tested, perfluorokerosene, was detected but could not effectively be determined quantitatively with the GC/MS. Its use should be restricted to investigations in which only its presence, and not its …

Subsurface Glacial Geology Of The Area Between The Tekonsha And Kalamazoo Moraines, Kalamazoo County, Michigan, Kim Finkbeiner

Masters Theses

Cross sections profiling the stratigraphy of the glacial sediments were created using the geological logs recorded on water well records. Glacial sediments in the study area comprise a large outwash complex between two moraines. The surficial landforms are the result of the last Wisconsinan advance and retreat through the area.

Cross sections contructed for this project reveal at least three major till units. An additional till unit contains a weathered soil sequence. Therefore, it is possible that this paleosol represents the Sangamon Interglacial period between the Wisconsinan and Illinoian stages. No obvious evidence of movement of the Saginaw Lobe remains …

Investigations Of Glacial-Drift Aquifer-Lake Interactions Using Hydrogeology, Geochemistry, And Stable Isotopes At Asylum Lake, Michigan, Vincent E. Buening

Masters Theses

A hydrogeological investigation of Asylum Lake and its associated unconfined glacial-drift aquifer in Kalamazoo, Michigan was undertaken to define the lake-aquifer interaction at the study area. In addition, the impact of development proximal to the study area on ground water and lake-water quality was evaluated. Hydrogeology, inorganic water chemistry, and stable isotopic ratios of deuterium to hydrogen were employed to establish the interaction of the lake and the aquifer.

The findings from this study indicated that: (a) the sandy unconfined glacial-drift aquifer discharges into the lake along its western margin and is recharged by the lake along its eastern margin; …

Structural Analysis Of The Hurricane Fault In The Transition Zone Between The Basin And Range Province And The Colorado Plateau, Washington County, Utah, Meg E. Schramm

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study defines fault segments and segment boundaries along the Hurricane fault in southwestern Utah and determines the geometric and kinematic relationship to other regional structures. Fault segment identification is critical for understanding fault processes and seismic risk; segment length is the maximum earthquake rupture length along a fault. Segment boundaries may act as barriers to earthquake propagation.

Normal fault segmentation only recently has received attention and has never been studied along the Hurricane fault. The fault changes strike along its length, and is thus a segmented fault. This study documents one nonconservative segment boundary and two fault segments, the …

Groundwater Flow And Elastoplastic Stress-Strain Model For Cohesive Soils With Application To Channel Bank Stability, Richard A. Rohlf, Billy J. Barfield, Gary K. Felton

KWRRI Research Reports

A saturated-unsaturated groundwater flow and elastoplastic stress-strain finite element model was developed for simulating the mechanical behavior of rill and gully sized channel banks. The model coupled the two-dimensional saturated-unsaturated groundwater flow equation with a plane strain formulation of the virtual work equation. The constitutive relationship used the modified Cam clay yield function. The model included the effects of seepage force and variation in soil cohesive strength due to changes in water content and void ratio. A staggered solution procedure was used in which the groundwater equation was solved first to determine seepage force and soil cohesive force, and then …

Landslide Inventory And Susceptibility Mapping Of The Upper Canyon Creek Basin, Cascade Range, Skamania County, Washington, Lawrence P. Growney

Dissertations and Theses

Contact relations, and bedrock and overburden characteristics for approximately 8100 ha of the upper Canyon Creek basin, Skamania County, Washington, have been assessed in order to determine the causes and extent of failures and to assign slope failure susceptibilities to the area. The study area is located in the western Cascade Range on land administered by the Gifford Pinchot National Forest. Clear-cutting over the past 30 years has impacted between 50% to 80% of the study area.

The total surface area occupied by failure deposits (198.6 ha) is less than 2.5% of the study area. Failures occur by one of …

The Influence Of Saprolite Composition Texture And Structure On Groundwater Flow In The Piedmont Province Henry County Virginia, John Thomas Russell

OES Theses and Dissertations

At a 500 acre site in Henry County, Virginia, differences in vertical hydraulic conductivity (K_V) and lateral hydraulic conductivity (K_H) measured in saprolites formed from the Fork Mountain biotite gneiss and the Leatherwood granite reflect the control of the fabric, texture, and structure of the parent rock preserved within the saprolite horizon. Using subsurface data collected from approximately 350 boreholes in conjunction with published information enabled various maps to be generated that identify the spatial relationships between geology and topography and their influence on the nature of the saprolite aquifer.

Measurements of K_H determined from …

The Geology Of Parrett Mountain, Oregon, And Its Influences On The Local Groundwater Systems, Brett Todd Brodersen

Dissertations and Theses

A geologic study of the Parrett Mountain area, located twenty miles (32 kms) south-southwest of Portland, Oregon, was initiated by the Oregon Water Resources Department. The main goal was to create a stratigraphic and structural model of Parrett Mountain in order to better understand the local basalt aquifers present there.

Previous geologic studies of the area revealed the mountain to be composed of Columbia River basalt. Field mapping and hand lithologic and geochemical analyses allowed the basalt to be subdivided into eleven basalt flows. These flows are as follows: (from oldest to youngest) the Wapshilla Ridge (WpR), the Ortley-Grouse Creek …

Sediment Yield Analysis Of Reservoir #1, Bull Run Watershed, West Cascade Mountains, Oregon, Doann M. Hamilton

Dissertations and Theses

Bull Run Watershed was set aside in late the 1800s as the water supply source for the City of Portland. Other than two dams being constructed, Reservoir #1 (1929) and Reservoir #2 (1962), development of the land had been minimal as public access was restricted. In the early 1960s, land management changed with increased road building and timber removal raising concerns about increased sediment discharge into the reservoirs. The objective of this study is to evaluate how much and how fast the sediment has accumulated in Reservoir #1, and to determine if the rate of sediment accumulation has changed over …

Coastal Crossing Of The Elastic Strain Zero-Isobase, Cascadia Margin, South Central Oregon Coast, Gregory George Briggs

Dissertations and Theses

The analysis of marsh cores from the tidal zones of the Siuslaw, Umpqua, and Coos River systems on the south-central Oregon coast provides supporting evidence of coseismic subsidence resulting from megathrust earthquakes and reveals the landward extent of the zero-isobase. The analysis is based on lithostratigraphy, paleotidal indicators, microfossil paleotidal indicators, and radiocarbon age. Coseismic activity is further supported by the presence of anomalous thin sand layers present in certain cores. The analysis of diatom assemblages provides evidence of relative sea-level displacement on the order of 1 to 2 m. The historic quiescence of local synclinal structures in the Coos …

Asymmetric Upwarp Of The Asthenosphere Beneath The Baikal Rift Zone, Siberia, Stephen S. Gao, Paul M. Davis, Kelly H. Liu, Philip D. Slack, Yu A. Zorin, Nikolai A. Logatchev, M. Kogan, P. D. Burkholder, Robert P. Meyer

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

In the summer of 1991 we installed 27 seismic stations about lake Baikal, Siberia, aimed at obtaining accurately timed digital seismic data to investigate the deep structure and geodynamics of the Baikal rift zone and adjacent regions. Sixty-six teleseismic events with high signal-to-noise ratio were recorded. Travel time and Q analysis of teleseisms characterize an upwarp of the lithosphere-asthenosphere boundary under Baikal. Theoretical arrival times were calculated by using the International Association of Seismology and Physics of the Earth's interior 1991 Earth model, and travel time residuals were found by subtracting computed arrival times from observed ones. A three-dimensional downward …

Problems Associated With Using Ground Penetrating Radar To Locate A Lnapl Plume, Jodie Mcneil

Masters Theses

The Crystal Refinery in Carson City, Michigan was the site used to test the hypothesis that Ground Penetrating Radar can locate LNAPL plumes. The contamination at the site is in the form of two tree product plumes and a dissolved plume. Three Ground Penetrating Radar antennas were used, a 100 MHz, a 300 MHz and a 500 MHz. Borings with a hand auger were made on some of the GPR lines. Gravel and coarse sand along with product in the form of residual stain and tree product were found in some locations. A vertical electrical sounding and a resistivity profile …
