Total Organic Carbon In A Glacial Aquifer: Measurement And Effects Upon Transport Of Organic Compounds, Jiang Wu

Masters Theses

Organic contaminant transport processes in subsurface systems have been paid increasing attention recently. Sorption of organic compounds on the aquifer solid matrix (retardation) is one of the most important processes influencing contaminant transport. The extent of sorption has been estimated by determination of organic carbon in aquifer materials and assumptions concerning sorption constants.

This paper focuses upon the sensitivity of organic contaminant transport to the total organic carbon (TOC) content in a natural aquifer. This study was composed of two phases. The first phase was methodology development and laboratory analysis of organic carbon contents in soil samples. Acidification and furnace …

The Effects Of A Wetland On Ground-Water Quality In An Agriculturally Impacted Aquifer, Marilyn Ann Betts

Masters Theses

Nitrate concentrations in excess of U.S. EPA standards have been documented for farm wells in an area where hog production and row crops are the predominant forms of agribusiness. The aquifer serving this area is in glacial deposits of interbedded sand, clay, gravel and till. The upper, unconfined, sand and gravel unit of the aquifer is connected to a flow-through wetland. Five well nests, with wells at various depths, were installed in and around the wetland. Samples were taken from the wells in both winter and summer to establish temporal and spatial changes in ground-water quality parameters.

Concentrations of nitrate, …

Magmatic Evolution And Eruptive History Of The Granitic Bumping Lake Pluton, Washington: Source Of The Bumping River And Cash Prairie Tuffs, John Frederick King

Dissertations and Theses

The 25 Ma Bumping Lake pluton ranges in composition from quartz diorite to granite with the granitic facies comprising approximately 90% of the pluton's surface area. The granite may be classified as calcalkaline, peraluminous and I-type with some Stype characteristics. A late-stage, mafic-poor facies fills cooling related extensional fractures. The pluton was passively emplaced into the Ohanapecosh Formation at a shallow level in the crust. Contact relationships vary from sharp where the contact is vertical to gradational at the roof of the pluton. Where gradational, stoped xenoliths from the roof of the pluton increase in size, angularity and retain more …

Magnitude Of Displacement And Styles Of Deformation On The Paris And Laketown Thrust Faults, Northern Utah, Richard D. Kendrick

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Surface geology is combined with abundant industry seismic-reflection and drill­-hole data in the central Bear River Range and Bear Lake Plateau to depict the forms and interactions of the Paris-Woodruff-Willard, Laketown-Meade-Home Canyon, and Crawford thrust faults. Displacement on the Paris thrust diminished to the south, and died out in splays where displacement was transferred to the Willard thrust. West of Woodruff, Utah, splays of the Laketown thrust deformed a complex footwall imbricate of the Willard thrust. To the east, a major northeast-striking Crawford thrust splay exhibits a change in slip vectors from east to southeast. Reorientation of these slip vectors …

The Tectonic Evolution Of The Panther Creek Half-Graben In East-Central Idaho, Brian F. Hammond

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An integrated field, petrographic, structural, and geophysical analysis of the Panther Creek half-graben (PCHG), in east-central Idaho, was undertaken to determine its tectonic origin. Two competing theories as to the origin of the PCHG exist. One suggests that it formed as part of the TransChallis fault system (TCFS), a system of northeast-trending normal faults, eruptive centers, and graben that formed in Middle Eocene time. The graben of this system are bounded by northeast-striking normal faults, and show evidence of syn-tectonic deposition of basin-filling volcanic strata. The other theory suggests that the PCHG may have evolved as a result of a …

Sedimentology And Foraminiferal Taphonomy In Siliciclastic Environments: The Northern Gulf Of California, Mexico, Liping Zhang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Holocene sediments from intertidal and shallow subtidal zones in Bahia la Choya, Mexico exhibit significant differences based on their mineralogical content, constituent composition, textural parameters, and foraminiferal assemblages. The intertidal sediments are characterized by low calcium carbonate content, being dominated by quartz, and are moderately well sorted and coarse skewed with a fine mean grain size {M_z = 2.73 phi}. Total numbers {living and dead} of benthonic Foraminifera per ml of sediment are relatively low (12/ml) in the intertidal zones. In contrast, the subtidal sediments are characterized by high calcium carbonate content, being dominated by molluscan shell fragments, and …

Studies Of The Effect Of Hydrophobic Filter Packs In Free Product Hydrocarbon Recovery Wells, Stephen J. Shank

Masters Theses

Most free product hydrocarbon recovery wells are filter packed in order to prevent aquifer material from entering the well and to increase their effective diameter. Historically there are five factors in filter pack designs: grain size, grain shape, mineralogy, uniformity, and the filter pack diameter. Previous laboratory experiments found that filter packs treated with a water repellant chemical could dramatically improve well performance. This adds wettability as a sixth factor.

A desorption experiment was conducted to determine the feasibility of using a chemically treated filter pack in the subsurface. Analytical results of the leachate from the chemically treated sand indicated …

The Relationship Between Basement Structure And Overlying Sediments In The Michigan Basin: A Detailed Gravity Investigation, Mitchell Joseph Gutaj

Masters Theses

A detailed gravity study consisting of 945 measurements was carried out in Branch County, Michigan. The objectives of this study are to determine if: (a) structural trends interpreted from regional gravity data in southwestern Michigan are also observed in a more detailed survey in Branch County and (b) any relationship exists between observed geophysical anomalies, geological structures and overlying basin sediments.

The resulting gravity map indicates that NW-SE, NE-SW, and N-S trends are more clearly identified comprising several elliptical highs and lows. Variations in the isopachs of some of the overlying Phanerozoic formations area are also coincident with gravity anomalies. …

Sporomorphs And Palynological Interpretations Of Lower Oligocene Strata From The Eastern Gulf Coast, U.S.A., Lisa M. Reeves

Opportunities for Undergraduate Research Experience Program (OURE)

The Vicksburg Group in the eastern Gulf Coast of the United States belongs to one of the most complete and continuous Paleogene strata in the world. Previous studies in this region have neglected the rich palynomorph assemblages of the Lower Oligocene units of the Vicksburg Group. Four samples from Wayne County Mississippi were analyzed for palynological information on the Vicksburg Group. The initial objective of the study was to understand the principles of palynology and the basis for sporomorph identification. A minimum of 300 specimens were counted per slide to determine the distribution of sporomorphs in the sediments. Two hundred …

Retrieval Of Sizes And Total Masses Of Particles In Volcanic Clouds Using Avhrr Bands 4 And 5, Shiming Wen, William I. Rose

Department of Geological and Mining Engineering and Sciences Publications

The advanced very high resolution radiometer (AVHRR) sensor on polar orbiting NOAA satellites can discriminate between volcanic clouds and meteorological clouds using two-band data in the thermal infrared. This paper is aimed at developing a retrieval of the particle sizes, optical depth, and total masses of particles from AVHRR two-band data of volcanic clouds. Radiative transfer calculations are used with a semi-transparent cloud model that is based on assumptions of spherical particle shape, a homogeneous underlying surface, and a simple thin cloud parallel to the surface. The model is applied to observed AVHRR data from a 13-hour old drifting cloud …

Environments Of Aeolian Deposition In South-Central Nebraska During The Last Glacial Maximum, Zhao-Dong Feng, William C. Johnson, Robert F. Diffendal Jr.

Robert F. Diffendal, Jr., Publications

The Peoria loess of south-central Nebraska, deposited approximately during the last Glacial Maximum, can be subdivided into three zones: an upper laminated loess and a lower massive loess, separated by a dark gley zone in which bison bones and spruce charcoal are found. The lower Peoria unit is characterized by high organic matter content, relatively high bulk density, and common root channels. The upper Peoria unit has rhythmic patterns of two orders: strongly gleyed and weakly gleyed zones alternating in couplets about 2-5 m thick, and coarse- and fine-grained laminae of second order, about 2-4 mm thick. The strongly gleyed …

Geomorphic And Structural Features Of The Alliance 1º × 2º Quadrangle, Western Nebraska, Discernible From Synthetic-Aperture Radar Imagery And Digital Shaded-Relief Maps, Robert F. Diffendal Jr.

Robert F. Diffendal, Jr., Publications

The digital shaded-relief map of the United States and the synthetic-aperture radar map of the Alliance Nebraska 1º x 2º area prepared by the U.S. Geological Survey (USGS) in the former case and for the USGS in the latter show oriented landforms and lineaments in northwest Nebraska. Parallel and subparallel hills and valleys developed on different geologic materials ranging from shales through sandstones to loess and eolian sand appear to be wind erosional features subsequently modified by running water. The long axes of these hills and valleys generally trend between N40"W and N50"W. Similar features also occur across major areas …

Geochemical Evidence Of Saharan Dust Parent Material For Soils Developed On Quaternary Limestones Of Caribbean And Western Atlantic Islands, Daniel R. Muhs, Charles A. Bush, Kathleen C. Stewart, Tracy R. Rowland, Russell C. Crittenden

United States Geological Survey: Staff Publications

Most previous workers have regarded the insoluble residues of high-purity Quatemary limestones (coral reefs and oolites) as the most important parent material for well-developed, clay-rich soils on Caribbean and western Atlantic islands, but this genetic mechanism requires unreasonable amounts of limestone solution in Quatemary time. Other possible parent materials from external sources are volcanic ash from the Lesser Antilles island arc and Saharan dust carried across the Atlantic Ocean on the northeast trade winds. Soils on Quatemary coral terraces and carbonate eolianites on Barbados, Jamaica, the Florida Keys (United States), and New Providence Island (Bahamas) were studied to determine which, …

Fossil Charcoal In Cretaceous-Tertiary Boundary Strata: Evidence For Catastrophic Firestorm And Megawave, Michael A. Kruge

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Organic matter separated from calcareous sandstone from the upper portion of a deep-water tsunami deposit at Arroyo el Mimbral, Taumalipas (Mexico), which marks the biostratigraphically-defined Cretaceous-Tertiary boundary, consists primarily of fossil charcoal, including semifusinite and pyrofusinite. Analytical pyrolysis-gas chromatography-mass spectrometry revealed the highly aromatic and polyaromatic character of the organic matter assemblage, typical of the products of partial combustion. The organic matter probably originated as terrestrial vegetation that was caught in a firestorm and subsequently transported far offshore in the backwash of a megawave. These data are consistent with the hypothesis of combustion of large masses of vegetation triggered by …

Sand And Gravel Resources Along The Ohio River Valley In Boone, Gallatin, And Carroll Counties, Kentucky, Eugene J. Amaral

Report of Investigations--KGS

Glacial outwash sand and gravel from three northern Kentucky counties in the Ohio River Valley have been analyzed in order to characterize their particle size, composition, morphology, and surface alteration and to determine the geologic significance of lateral and stratigraphic variations in these sediment properties. The late Wisconsinan-age deposits, actively mined in terraces along the Ohio River, are composed of moderately sorted sand and a poorly sorted, bimodal mixture of sand and gravel. A systematic pattern of regional grain-size variation was found to be associated with the confluence of the Great Miami River, a major meltwater sluiceway entering the Ohio …

Source Rock Geochemistry Of The Southern Tyee Basin, Southwest Oregon, David E. Long

Dissertations and Theses

This study examined source rock geochemistry of the southern Tyee Basin. Total organic carbon, rock-eval pyrolysis, vitrinite reflectance, thermal alteration index and visual assessments were performed on splits from cutting samples from five wells and on outcrop samples from four measured sections. Organic matter was found to be dispersed, averaging about 0.5 weight percent. The organic matter is primarily terrestrial in origin, or type I l l , with low potential for gas production and no oil potential. Three coal samples are clearly the richest sources of organic matter examined in this study.

Storm Dominated Channel Sequences On A Shallow Marine Shelf: Morrowan Of Northwest Arkansas, Kimberley R. Jones, Doy L. Zachry

Journal of the Arkansas Academy of Science

The Brentwood Member of the Bloyd Formation (Morrowan, Pennsylvanian) in northwestern Arkansas contains stratigraphic sequences deposted by tropical storms in middle shelf environments. The deposits are confined to shallow channels incised by strong unidirectional currents into an interval of shale deposited during fair weather conditions. Complete storm sequences reflect initial bottom currents of high competency that declined through time and were succeeded by wave generated oscillatory activity. The storm succession consists of an erosion surface followed by a basal pebble conglomerate, massive grainstone and packstone, whole-fossil wackestone, hummocky cross-strata and a swell lag of platy crinoidcalyxes. As storm activity ceased, …

Impact Of Riparian Grass Filter Strips On Surface-Water Quality, Alex W. Fogle, Daniel I. Carey, Billy J. Barfield, Robert L. Blevins, Vasilios P. Evangelou, Cora E. Madison, Shreeram P. Inamdar

Information Circular--KGS

The effectiveness of natural riparian grass filter strips in removing sediment and agricultural chemicals from surface runoff was studied using no-tillage and conventional-tillage erosion plots. Runoff from the tillage plots was directed onto 4.57, 9.14, and 13.72 m (15, 30, and 45 ft.) length filter strips, where the inflow and outflow concentrations and sediment size distributions were measured. Trapping efficiencies for sediment and agricultural chemicals typically ranged near or above 90 percent, mainly because of high infiltration rates. The filters also significantly reduced peak discharge concentrations, which reduced the impact of sediment and agricultural chemicals on receiving surface waters.

Available Coal Resources Of The Salyersville South 7.5-Minute Quadrangle, Magoffin County, Kentucky, Robert E. Andrews, Gerald A. Weisenfluh, John K. Hiett, Richard E. Sergeant
