Gas Exploration In The Devonian Shales Of Kentucky, Terence Hamilton-Smith

Bulletin--KGS

Devonian black shales constitute a major economic resource in Kentucky. These shales, known variously as the Ohio, Chattanooga, and New Albany Shales, are between 50 and 1, 700 feet thick and occur both in outcrop and in the subsurface, buried as deep as 4,200 feet below sea level.

Total gas in place for the Devonian shales in Kentucky is estimated to be between 63 and 112 trillion cubic feet; between 2 and 28 percent is recoverable. Known shale gas accumulations include the giant Big Sandy Field of eastern Kentucky and adjacent \/Vest Virginia, as well as a number of smaller …

Available Coal Resoures Of The Handshoe 7.5–Minute Quadrangle, Knott County, Kentucky, Gerald A. Weisenfluh, Robert E. Andrews, John K. Hiett, Richard E. Sergeant

Information Circular--KGS

Coal resources available for mining have been estimated for the Handshoe Quadrangle within the Hazard Coal Reserve District of the Eastern Kentucky Coal Field. Twelve coal beds within the quadrangle are potentially mineable and comprise the basis of these resource estimates. Seven of these beds have been commercially developed, but only four have produced more than 1 million tons: the Tiptop, Hazard No. 8, Hazard No. 4, and Upper Elkhorn No. 3. A computerized Geographic Information System was used to calculate estimates of original, mined-out, and remaining resources, restrictions to mining, and available resources.

Quality Of Private Ground-Water Supplies In Kentucky, Daniel I. Carey, James S. Dinger, O. Barton Davidson, Richard E. Sergeant, Joseph L. Taraba, Thomas W. Ilvento, Steve Coleman, Rayetta Boone, Laura M. Knoth

Information Circular--KGS

About 3.7 million people live in Kentucky, of which 1.9 million (52 percent) live in urban areas (roughly defined as any community with 2,500 or more people) and 1.8 million (48 percent) live in rural areas (University of Kentucky, 1993). Figure 1 summarizes sources of drinking water for Kentucky residents. About 70 percent of Kentuckians get their daily supply of water from surface-water sources - lakes and streams; about 25 percent get their water from ground-water wells; and about 5 percent get their water from other sources - springs, cisterns, ponds, or hauled water.

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 …

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.

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.

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 …

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 …

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 …

Seasonal Sediment Migration And Sediment Dynamics On Sandy Point Beach, San Salvador Island, Bahamas, Nicholas T. Loizeaux, H. Allen Curran, William T. Fox

Geosciences: Faculty Publications

A study of the dynamics of Sandy Point Beach along the southwestern corner of San Salvador Island over an eighteen-month period, beginning in June, 1990, has revealed that two seasonal phases of sediment transport are operative. Based primarily on analyses of the grain-size parameters of sand samples collected from the beach in June, 1990, a northerly direction of sediment transport was detected. This is herein termed the Spring/Summer phase of transport, and it results from the energy of waves generated by the prevailing easterly trade winds. Continued profiling of the beach in December, 1990, and January, 1992, revealed that a …

Long-Term, Seasonal, And Event-Driven Sediment Movement On East Beach, San Salvador Island, Bahamas, Andrew L. Brill, H. Allen Curran, William T. Fox

Geosciences: Faculty Publications

East Beach is a modern, medium-energy shoreline located on the northeast coast of San Salvador Island, Bahamas. Stake and horizon profiles were made at 9 sites along a 1-km section of the beach in June, 1990, and every six months thereafter through January,1992. These observations appear to confirm that East Beach is a prograding shoreline, building onto the eastern shelf of the island. Seasonally corrected volume calculations indicate that between June, 1990 and January, 1992 approximately 14,000 m³ of new sand per kilometer were added to the East Beach system, with most of the sand likely derived from the …

Solidification And Morphology Of Submarine Lavas: A Dependence On Extrusion Rate, Ross W. Griffiths, Jonathan H. Fink

Geology Faculty Publications and Presentations

The results of recent laboratory experiments with wax extruded beneath relatively cold water may be extrapolated to predict the surface morphology of submarine lavas as a function of the extrusion rate and melt vIscosity. The experiments with solidifying wax indicated that the surface morphology was controlled by a single parameter, the ratio of the time taken for the surface to solidify, and a time scale for lateral flow. For submarine basalts a solution of the cooling problem (which is dominated by conduction in the lava but convective heat transfer in the water) and estimates of lava viscosities place this parameter …

The Morphology Of Lava Flows In Planetary Environments: Predictions From Analog Experiments, Ross W. Griffiths, Jonathan H. Fink

Geology Faculty Publications and Presentations

The rates of surface cooling and lateral spreading are evaluated for lava flows on the surface of Earth, Venus, Mars, the Moon, and 10. Differences between the flow morphologies expected in these environments are then predicted under the assumption that the results of recent laboratory simulations oflavas using wax extruded beneath cold water (Fink and Griffiths, 1990) can be carried over. These experiments involved the spreading of viscous liquid under gravity in the presence of a solidifying surface crust and revealed a set of four distinct surface morphologies. Transitions from one morphology to the next occurred in a well-defined sequence …
