Estimation Of A Water Budget For Agnes Marsh, Grand Forks County, North Dakota, Allen E. Comeskey

Theses and Dissertations

Agnes Marsh is a semipermanent wetland in the Red River Valley of northeastern North Dakota. The marsh overlies and is in direct hydraulic connection with the unconfined Elk Valley aquifer. Recent irrigation development nearby raised concerns about the hydrological impact to the marsh by a declining water table in the aquifer. The purpose of this study was to determine how Agnes Marsh interacts with the underlying Elk Valley aquifer and how sensitive the marsh is to declining water levels in the aquifer.

Three methods were used to assess how the marsh interacts with the aquifer. First, stratigraphic analysis revealed the …

Petrography And Inorganic Geochemistry Of The Rosebud Coal Seam At The Absaloka, Big Sky And Rosebud Mines, Powder River Basin, Montana, Lingbu Kong

Theses and Dissertations

Quantitative maceral and microlithotype analyses, huminite reflectance measurements and inorganic constituent analyses of the samples of the Rosebud subbituminous coal seam from the Absaloka, Big Sky and Rosebud Mines were used in the interpretation of the depositional environment of the seam and for prediction of ash formation during combustion. The mean huminite reflectance varies from 0.31% at the Rosebud Mine to 0.34% at the Absaloka Mine and 0.39% at the Big Sky Mine, indicating that the coal rank is transitional from lignite to subbituminous C. Despite the variation in huminite reflectance, samples from the three mines are similar in mean …

Identifying Key Variables Associated With The Temporal And Spatial Distribution Of Prolific Marine Petroleum Source Rock (Mpsr) Units And Its Application To The Taconic Foreland Basin, Eastern New York, C. Mark Achong

Geology Theses and Dissertations

Correctly identifying key variables associated with the temporal and spatial distribution of prolific marine petroleum source rock (MPSR) units is of critical importance towards the future development of models accurately predicting their existence and effective exploitation. The geographic positioning and prevailing paleoclimatic conditions on paleocontinental reconstructions, in combination with the processes controlling the drowning of continental margins and parameters associated with the establishment of high biologic productivity and long term anoxic conditions within the water column, have been pursued as first-order constraints controlling the development of some prolific marine petroleum source rock (MPSR) deposits. From this, a model has been …

Correlation Of The Tioga Bentonites Using Rhyolitic Melt Inclusions Found In Quartz Phenocrysts As Geochemical Fingerprints, John W. Waechter

Geology Theses and Dissertations

The Tioga bentonites were first noted by Fettke in 1931 from well cuttings in the Tioga gas fields of Tioga County, Pennsylvania. They have been used by many investigators (Oliver, 1954, 1956; Dennison, 1963; Dennison and Textoris, 1967, 1978; Epstein, 1986; Smith and Way, 1983; Way et al., 1986) as a time-plane to correlate stratigraphic units from eastern Pennsylvania to Illinois and from southern Ontario to Virginia. The Tioga bentonites are recognized as seven major volcanic ash layers labeled Tioga-A - Tioga-G as well as several minor layers labeled Tioga-A1 - Tioga-A3 (Way et al., 1986). They occur within the …

A Paleoseismic Investigation Of The Mcgregor Fault, East-Central New York, Steven J. Tice

Geology Theses and Dissertations

The structural disposition and movement potential of the McGregor Fault System in Eastern New York State are reviewed from the perspective of a paleoseismic investigation. The McGregor Fault zone has been located beneath deltaic sediments west of West Glens Falls using commercial and residential bore hole data and microgravity surveys. A 34 m long trench was excavated in overburden near the western margin of the McGregor Fault zone to a depth of 3.2 m. Stratified fluvially deposited sediments were exposed which showed no evidence of earthquake induced deformation or offset. However, the overburden present here does not possess optimal qualities …

Trace-Element Modelling Of Melting In Spinel Peridotites, Susanne Petra Vogel

Geology Theses and Dissertations

This study addresses three independent topics related to trace element modeling of spinel peridotites that are suggested by the pioneering work of Johnson et al. (1990) on abyssal harzburgites.
First, the fractional non-modal melting equation derived by Johnson and coworkers (1990) is algebraically modified to present a "one-element/two-phase" model. This model suggests a simple test for estimating mantle heterogeneity in the source rock of spinel lherzolites. This model is applied to data from the literature for samples from Dreiser Weiher, Germany; San Luis Potosi, Mexico; and Western Victoria, Australia.
Second, trace elements in clinopyroxenes of abyssal peridotites and continental spinel …

Iceberg Severity Off The Canadian East Coast (An Analysis Of The 1991 Iceberg Season), Jerome Edward Salloum

Theses and Dissertations (Comprehensive)

The 1991 iceberg season on the Grand Banks was the second most severe on record. Over a 218-day period, a total of 2002 icebergs traversed latitude 48°N. Percentages of sightings involving medium and large icebergs greatly exceeded normal values. Thus, the season was mxtstanding, not only in terms of flux numbers, but in terms of total ice mass delivered. Assuming that this flux anomaly is the product of more efficient advection and less efficient ablation and notzsome sudden surge in upstream berg production, the study investigates various atmospheric and sea surface conditions as contributing factors to a near record iceberg …

Using Fourier Transform Analysis To Extract Information From The Shapes Of Folded Layers, Thomas Billiard

Honors Papers

Objective methods of fold shape analysis are nessesary to better understand the behavior of folds and the folding process. I examined two methods of analysis, and used a method based on the Fourier Transform to show that the method based on the Fourier Series was insufficient for identifying shape characteristics of aperiodic natural fold trains. I also showed that the Fourier Transform method accessed information that was inaccessable using the Fourier Series method.

The Origin Of Mount St. Helens Andesites, Diane R. Smith, W. P. Leeman

Earth and Environmental Geosciences Faculty Research

Mount St. Helens volcano has intermittently produced mainly dacitic products but occasionally erupted a more diverse suite of lavas including basalts and andesites. Petrogenetic relations between these magmas provide insight into the dynamics of the subjacent magma system. Mineralogical and geochemical features of representative lavas erupted during the past 2200 years can distinguish three basaltic and three andesitic variants. The mafic lavas include: (a) transitional, olivine + plagioclase basalts with low K₂O and incompatible trace-element abundances: (b) calc-alkaline, olivine + plagioclase ± clinopyroxene basalts enriched in K ₂O, TiO₂, and incompatible trace elements: and (c) …

Bulletin 4274 - Tree Planting On The High Rainfall Coastal Plain, Don Bennett, Richard George

Bulletins 4000 -

Careful planning can mean the difference between the success or failure of a tree planting program . Healthy , well-e stablished trees stand a better chance of survival, grow faster and are more resistant to insect attack. The need for time-consuming watering in summer is also eliminated.

The high rainfall coastal plain extends from Perth to Busselton and inland to the Darling Scarp. It receives about 800 to 1000 mm annual rainfall.

Site preparation is ideally started in summer. For a winter planting, decide before March where to plant, which varieties and how many trees to plant. Early planning allows …

Aspects Of Gold Recovery From An Indigenous Ore, Cormac Patrick Mcnamee

Masters

This project involved the investigation into the basic electrochemistry of the thiourea-formamidine disulphide redox couple and an estimation of the formal potential, Eo1 for the couple. By carrying out optimisation experiments on the leaching of gold from an ore sample from the Avoca mine in Co. Wicklow, the optimum leaching conditions were determined for maximum gold extraction. The effects of various organic and inorganic species on the adsorption of gold onto activated carbon and modified peat were investigated with the use of factorial designed experiments. The Langmuir Isotherm model was applied to estimate the capacity of the carbon for these …

Time-Stratigraphic Reconstruction And Integration Of Paleopedologic, Sedimentologic, And Biotic Events (Willwood Formation, Lower Eocene, Northwest Wyoming, U.S.A.), Thomas M. Bown, Mary J. Kraus

United States Geological Survey: Staff Publications

Relative paleosol maturities are inversely proportional to the accumulation rates of the sediment upon which they formed, and are therefore excellent relative indicators of how much geologic time elapsed between any two horizons. An empirically-based model is advanced using paleosol maturities to estimate the relative geologic time separating any stratigraphic levels within the lower Eocene Willwood Formation. The revised Willwood time stratigraphy from this analysis helps evaluate the nature, tempo, and possible causes of three major episodes of mammalian appearance and disappearance. These faunal events are directly correlated with certain aspects of paleosol evolution in the Willwood Formation. That evolution …

Depositional And Diagenetic Controls On Porosity Evolution In The "C" Zone, Red River Formation (Upper Ordovician), Divide County, North Dakota, John S. Fox

Theses and Dissertations

Carbonates and evaporites in the "C" zone c: the Red River Formation (Upper Ordovician) in the subsurface of Divide County, North Dakota, were studied in order to determine the geologic framework of porosity evolution in this important hydrocarbon-producing formation. Examination of 28 cores, petrographic analysis, geochemical analysis, and mapping based on 120 geophysical log suites allowed the characterization of "C" zone lithologies and diagenetic features and suggests that the entire "C" zone was deposited subtidally in an increasingly restricted basin, rather than in a subtidal to supratidal regressive sequence as interpreted by others in different parts of the basin.
