Tectonic History Of Billings And Southern Mckenzie Counties, Southwestern North Dakota, John J. Crashell

Theses and Dissertations

Billings and southern McKenzie Counties contain about 40 active oil and gas fields. In the same area, two major structural highs and several minor ones can be recognized. The first of these, the Billings anticline, extends approximately 60 km (18 mi.) along a north-south line in central Billings County, and is composed of two parallel folds. A second major structure, here termed the Rough Rider anticline, lies west of the Billings anticline, and also extends about 60 km (18 mi.) along a north-south line from north-central Billings County into southern McKenzie County. Both of these structures are fault-bounded on their …

Speciation Of Troglobites: Studies In The San Antonio Cave (Oaxaca, Mexico), Horst Wilkens, Peter Junge, Thomas G. Langecker

International Journal of Speleology

The phylogenetically young species community of San Antonio Cave (Oaxaca, Mexico) exemplifies the hypothesis that speciation of troglobites can occur in close contact with epigean predecessors. In a subterranean creek which continues outside with a rich epigean fauna, four troglobitic aquatic crustacean and one fish species (Rhamdia reddelli, Pimelodidae) were studied. Today not a single surface specimen can be found in the cave waters although several epigean species are troglophilic and/or are the ancestors of cave forms in other parts of Mexico. The absence of epigean invaders is attributed to the presence of specimens of some of the …

Metabolic Efficiency And Regulation Of Body Weight: A Comparison Between Life In Hypogean And Epigean Ecosystems, Jayant Biswas

International Journal of Speleology

In the present study metabolic efficiency in the epigean and hypogean populations of Nemacheilus evezardi (Day) was examined. Different experiments were conducted, in both populations, by keeping them either in restricted oxygen or restricted feeding conditions, including starvation. Results clearly show that the rate of oxygen consumption for the hypogean population was significantly less as compared to its epigean counterpart. Further, results also suggest that the hypogean population has a tremendous capacity to maintain its metabolic activity and regulate its body weight under severe conditions characterized by an absence or a limited supply of food.

Observations On The Biology Of Spelaelacris Tabulae Peringuey (Orthoptera, Rhaphidophoridae), From The Wynberg Cave (Capetown, South Africa), Gianmaria Carchini, Claudio Di Russo, Mauro Rampini

International Journal of Speleology

Data on the age structure, fecundity, egg morphology and feeding habits of the Spelaeiacris tabulae population from Wynberg cave are reported and compared with other Rhaphidophoridae species. S. tabulae shows a certain degree of adaptation to cave life, as usual in the other temperate species of Rhaphidophoridae.

Revision Of The Genus Troglophilus (Orthoptera, Rhaphidophoridae) In Crete, Greece, Dimitrios Kollaros, Kaloust Paragamian, Anastassios Legakis

International Journal of Speleology

The genus Troglophilus (Orthoptera, Rhaphidophoridae) from Crete is revised using new data from specimens collected recently. The three previously reported species are considered to be only one, T. spinulosus, on the basis of morphological, ecological and distributional similarities. The species is more fully described and notes are given on its ecology.

Population Size Of Pyrenean Troglobiont Coleopters (Speonomus Species) In A Cave In Belgium, Raymond Tercafs, Christine Brouwir

International Journal of Speleology

The population size of three troglobitic species of Speonomus (Coleoptera Bathysciinae) from the Pyrenees, intentionally introduced in 1969-1970 into the “Grotte de Ramioul” cave (Province of Liège, Belgium) has been studied using the mark-recapture technique. It has been shown that the three cave levels possess large Speonomus populations (upper network: 12,718; middle network: 13,902; lower network: 18,249 individuals) and that the superficial underground environment is also colonized, including the schist area. The most abundant species is Speonomus longicornis (relative frequency between 0.73 to 0.89). The two other species are present in the relative frequency between 0.04 and 0.23 for S. …

Late Holocene Paleoseismicity Along The Northern Oregon Coast, Mark Edward Darienzo

Dissertations and Theses

Marsh paleoseismological studies were conducted in four bays (Necanicum, Nestucca, Siletz, and Yaquina) along the northern Oregon coast and compared with completed studies in two other bays (Netarts and Alsea). Coseismically buried peats were identified in all bays, based on 1) abrupt contacts, decreases in organic content, increases in sand content, increases in beach sand, and changes in diatom assemblages, all from the peat to the overlying sediments, 2) distinct sandy layers and key plant macrofossils, such as Triglochin, above the buried peat, and 3) widespread correlation of the buried peats within the bay. The stratigraphy and the ages and …

Pollen Analysis Of A Late Wisconsinan Deposit In East-Central Iowa, Barbara Ann Berquam

Dissertations and Theses @ UNI

Peat samples from a temporary exposure in the Early Phase High Terrace of the Iowa River near Iowa City, Iowa, were analyzed for pollen. The pollen sequence, dated at 24,570 +/- 200 to 18,620 +/- 140 B.P.·, can be divided into three zones based on pollen percentages. In the basal zone (zone-1), arboreal pollen is dominated by Pinus (pine), with lesser amounts of Picea (spruce), and is interpreted to represent a Pinus-Picea boreal forest. Picea pollen percentages increase through the intermediate zone (zone-2) of the sequence as Pinus pollen percentages decline, indicating a transition to a Picea-dominated boreal forest. A …

The Magmatic History Of An Aubrite Parent Asteroid: Evidence From Igneous Clasts And Trace Elements, Maya Monica Wheelock

Earth and Planetary Sciences ETDs

Norton County aubrite contains numerous igneous-textured clasts that survived severe brecciation. These clasts were studied in order to obtain information about the suite of original igneous lithologies that crystallized on an aubrite parent body. The majority of igneous clasts are pyroxenites (enstatite, with minor diopside, +/- forsterite) and orthopyroxenites (enstatite, +/- forsterite). Phase relations and textural evidence are consistent with formation from a nearly pure enstatite magma body or magma ocean, at (or near) the surface of the parent body.

A new sulfide-dominated lithology was identified in Norton County. The sulfide portion is dominated by coarse-grained oldhamite (CaS) containing rounded …

Radon Contamination Of Residences In A City Built Upon A Karst Landscape Bowling Green, Warren County, Kentucky, James William Webster

Masters Theses & Specialist Projects

The United States Environmental Protection Agency (EPA) estimates that 8 to 12% of U.S. homes have radon concentrations that equal or exceed 4 picocuries per liter (pCi/l). A statewide screening of Kentucky by EPA resulted in an average residential radon concentration of 2.8 pCi/l with 17% of the homes at or above 4 pCi/l. EPA requires routine monitoring and maintenance or worker health records in mines and caves having radon daughter concentrations at or above 0.30 working levels (WL).

Bowling Green is a city located in a karst region of south central Kentucky. Residents of Bowling Green have been subjected …

Reservoir Geology Of The Dundee Limestone, West Branch Field, Michigan, Brendan Ciaran Curran

Masters Theses

West Branch field is a low-relief, NW-SE-trending anticline near the center o f the Michigan basin. Since 1934, the Dundee Limestone (Middle Devonian) has produced over 12 million barrels of oil from this field. From core studies, six depositional facies types were recognized in the Dundee. These are dominated by bioclastic carbonate sand facies deposited in normal-marine shelf settings. Although burial cements have occluded some porosity, carbonate sand facies have retained significant primary interparticle porosity and are the most important reservoir rocks. Micritic facies with restricted faunal assemblages are present at the top of the Dundee. The top 10 to …

Spatial And Temporal Variations Of Synthetic Organic Compounds In The Contaminant Plume Emanating From The Kl Landfill, Lynn Diane Broede

Masters Theses

Thirty-one synthetic organic compounds have been detected in samples collected from the KL Landfill contaminant plume from March, 1980 to March, 1986. Two groups of organic compounds have been delineated based on their occurrence, concentrations, and persistence throughout the 7-year monitoring period.

Changes in plume geometry and concentration have been studied relative to time, and concentration variations have been related to selected inorganic plume parameters, distance from the landfill, and precipitation. The spatial and temporal distribution of the organic compounds are attributed to biodegradation, three biotransformation sequences, physical properties of the organics and other factors. Three abbreviated anaerobic biotransformation sequences …

A Report On Black-Tailed Prairie Dogs In Nebraska, Their Biology, Behavior, Ecology, Management, And Responses To A Visual Barrier Fence, Nancy S. Foster

School of Natural Resources: Dissertations, Theses, and Student Research

I examined the effects of a visual barrier fence, which had a see-through visibility of 600/0, on the foraging, vigilance, and aggressive behaviors of adult female black-tailed prairie dogs from June through August 1990 in central Nebraska. I also examined changes in their home ranges and use of an area in response to this fence. Prairie dogs prefer an open view of their surroundings. Therefore, I expected animals near a visual barrier to spend more time in vigilance and aggression, and less time foraging. Adult female prairie dogs exposed to the visual barrier devoted more time to foraging and less …

Cambrian-Early Ordovician Sequence Stratigraphy And Mount Simon Sandstone Petrology-Michigan Basin, Jeffrey T. Cottingham

Masters Theses

Michigan subsurface correlation is complicated in the Cambrian-Early Ordovician section due to limited availability of rock data. Core and cuttings examination demonstrate that similar stratigraphic sequences exist between the Michigan Basin and surrounding regions. Lithofacies in Wisconsin outcrop are similar to their basinal counterparts, and are correlated on the basis of sediment types, sedimentary structures, and the sequence stratigraphic concept.

The Mount Simon Sandstone in Michigan correlates with that observed in Illinois, Wisconsin, and Iowa. Isopach data throughout the Midwest indicate a single depocenter in Northeastern Illinois. Sedimentary structures and lithology indicate a subtidal environment that may be a progradational …

Hydrogeology And Hydrogeochemistry Of The Shallow Alluvial Aquifer Zone, Las Vegas Valley, Nevada, Harry Stephen Wild Jr.

UNLV Theses, Dissertations, Professional Papers, and Capstones

In Las Vegas Valley, Nevada, the shallow alluvial aquifer zone is a possible source of contamination to the principal alluvial aquifers that provide 30% of the public drinking water supply for the valley. Development of the principal aquifers has lowered pressure head in the principal aquifers and created the potential for downward seepage from the shallow aquifer zone. This study was undertaken to characterize the hydrogeology and hydrogeochemistry of the shallow alluvial aquifer zone and to compare the hydrogeochemistry of the shallow and principal alluvial aquifer zones.

A 37 well shallow ground water monitoring network was established and water-level, water-quality, …

Horticultural Capability Study Of Soils Adjacent To Plantations At Carnarvon, Western Australia, M R. Wells, J A. Bessell-Browne

Resource management technical reports

A detailed soil survey and horticultural capability assessment was undertaken over 1,804 ha of land adjacent to existing plantations on levees of the Gascoyne River near Carnarvon. The study provides mapped land resource data and advice in relation to land management and the possibility of further land release for horticulture. In the assessment of horticultural capability primary consideration has been given to the risk of erosion during flood events, to salinity, and to soil drainage conditions.

A Hydrogeological And Hydrogeochemical Investigation Of Groundwater At A Landfill For Sludge From The Kalamazoo Wastewater Treatment Plant, Richard Howard Christensen

Masters Theses

Major cations and anions were analyzed to determine groundwater chemistry at a site used for the disposal of municipal sludge in the late 1960s and contaminated Portage Creek sedimem dredged in the late 1970s. The disposal site consists of five unlined basins constructed over 50 to 100 feet of stratified sand and gravel outwash underlain by silt and clay. Groundwater in the outwash is unconfined and flows from east to west. A groundwater divide in the center of the site produces local divergent flow to the northwest and southwest. Measurements of chemical constituents indicate that three factors influence groundwater chemistry …

Geochemistry Of Metal Segregation In Aubrites, And The Origin Of Their Metallic Phases, Ignacio Casanova

Earth and Planetary Sciences ETDs

In this work, I have carried out a petrographic and geochemical study of the metallic particles present in aubrites with the aim of constraining ideas about their origin and evolution. The extremely low oxygen fugacities under which enstatite meteorites formed (e.g. Larimer and Buseck, 1974; Fogel et al., 1989) and their consequent unique composition make interpretations difficult due to the lack of experimental data on highly reducing systems. I have tried to overcome the paucity of experimental data by using a theoretical thermodynamic approach to study the significance of such unique compositions based on three main themes: (1) the …

Compositional Diversity Of Late Cenozoic Basalts In A Transect Across The Southern Washington Cascades: Implications For Subduction Zone Magmatism, W. P. Leeman, Diane R. Smith, W. Hildreth, Z. Palacz, N. Rogers

Earth and Environmental Geosciences Faculty Research

Major volcanoes of the Southern Washington Cascades (SWC) include the large Quaternary stratovolcanoes of Mount St. Helens (MSH) and Mount Adams (MA) and the Indian Heaven (IH) and Simcoe Mountain (SIM) volcanic fields. There are significant differences among these volcanic centers in terms of their composition and evolutionary history. The stratovolcanoes consist largely of andesitic to dacitic lavas and pyroclastics with minor basalt flows. IH consists dominantly of basaltic with minor andesite lavas, all erupted from monogenetic rift and cinder cone vents. SIM has a poorly exposed andesite to rhyolite core but mainly consists of basaltic lavas erupted from numerous …

Implications Of Thermal Events On Thrust Emplacement Sequence In The Appalachian Fold And Thrust Belt: Some New Vitrinite Reflectance Data, Sharon E. Lewis, James C. Hower

Center for Applied Energy Research Faculty and Staff Publications

Interpretation of existing geothermometry data combined with new vitrinite reflectance data, within the framework of a detailed composite tectonic setting, elucidates the evolution of structural sequencing of thrust sheets during the Alleghanian event in the Valley and Ridge Province in Virginia. That the Pulaski thrust sheet preceded the Saltville thrust sheet in the emplacement sequence, and that both reached thermal maxima prior to, or during, respective emplacement may be inferred from vitrinite and other geothermometry data. In contrast, the Narrows and St. Clair thrust sheets probably each attained their thermal maximum after emplacement. New vitrinite reflectance data are consistent with …

Cinder Cone Clustering In The Transmexican Volcanic Belt: Implications For Structural And Petrologic Models, Charles B. Connor

School of Geosciences Faculty and Staff Publications

Cinder cone distributions have most often been characterized using univariate statistics. Here a new technique to volcano distribution studies, cluster analysis, is applied to cinder cone distribution in the central TransMexican Volcanic Belt (TMVB). A total of 1016 cinder cones are identified over an area of approximately 60,000 km2. Application of cluster analysis reveals structure in cinder cone distribution. Using a search radius parameter of 16 km, 75% of the cinder cones within the central TMVB are found within eight clusters of 45–159 cones each. These clusters are each 2000 to 5000 km2 in area. Only 22 cones are found …

Hydrology Of A Large, Closed Arid Watershed As A Basis For Paleohydrological And Paleoclimatological Studies In The Mojave River Drainage System, Southern California, Yehouda Enzel

Earth and Planetary Sciences ETDs

A physical link between anomalous, present-day atmospheric circulation patterns over the North Pa1cific Ocean, extreme storms in southern California, the largest floods of record and lake stands in the Mojave River watershed in the Mojave Desert is demonstrated by analyzing hydrologic and climatic data. This link is then used as a modem analog to interpret hydroclimatic conditions during the latest Quaternary recorded in lake deposits in the Silver Lake playa, the terminal basin of the of the Mojave River.

The Mojave River filters out small to medium floods by discharge loss through infiltration into the alluvial aquifer and allows only …

Hydrogeology And Water Budget Analysis Of Two Interdunal Ponds Nags Head Woods Ecological Preserve, Dare County, North Carolina, Richard A. Hisert

OES Theses and Dissertations

Ground-water-fed interdunal ponds in Nags Head Woods Ecological Preserve lose as much as 7600 m³ yr^-1 of water through evaporation. This withdrawal of groundwater is sufficient to significantly alter flow patterns through the surficial aquifer on Bodie Island, N.C. Statistical analyses of evaporation estimates derived by various methods indicate a weak correlation, (r²=0.4-0.5) between pan evaporation data from Aurora, N.C. and pond evaporation at Nags Head Woods calculated by water budget analyses.

Results of stratigraphic and pedologic analyses in and around the ponds indicate that the ponds formed after development of multiple generations of dunes. This …

Trace Metals And Pyrite In Sediments Of Chesapeake Bay, Robert S. Kluckhohn

OES Theses and Dissertations

The formation and cycling of iron sulfides within anoxic sediments can affect the cycling of trace metals. The sediments at station CB-27 (near Annapolis, Maryland) in Chesapeake Bay were rich in FeS (39% of TS), low in greigite (3.6% of TS), and has a relatively constant pyrite concentration (50 - 60% of TS) with depth. The percent composition of total metals in pyrite were 25.7% cu, 11.8% Zn, 15.8% Fe, and non-detectable to 2.1% Cd. At Station CB- 28 (near the Choptank River), the sediments were low in FeS (1.7% of TS), richer in greigite (up to 14% of TS), …
