Geological Review Of Department Of Energy Proposed Sites In Minnesota For High-Level Radioactive Waste Disposal, Brenda Lorinser

Journal of the Minnesota Academy of Science

The Department of Energy (DOE) proposed three potentially acceptable sites for high-level radioactive waste disposal in Minnesota. These sites were chosen on the basis of the nature of the exposed or near surface crystalline rock bodies they contain. However, the accuracy of the data used by the DOE in choosing these sites is variable, from excellent to poor.

Potential Geologic Hazards Near The Thistle Landslide, Utah County, Utah, United States Geological Survey

All U.S. Government Documents (Utah Regional Depository)

In mid-April, 1983, an old landslide near Thistle, Utah, began to move, and within days had blocked Spanish Fork Canyon. As the slide's movement continued, construction crews gradually converted the toe of the slide into an earth-filled dam--Thistle dam--that impounded northwest-flowing Spanish Fork River. The resultant reservoir, known as Thistle Lake, was subsequently drained because of uncertainty about the stability of the dam. Recently, officials of Utah County have explored various alternatives for a water-retention structure in the area, including utilization of Thistle dam. The Thistle Slide Committee, established by the State of Utah to evaluate the suitability of using …

Chemical Quality Of Ground Water In Salt Lake Valley, Utah, 1969-85, United States Geological Survey

Eocene Castle Hayne Limestone, –27.4m to 15.2m BMSL (base of casing).

The Peedee Formation consists of moderately indurated, very fine to fine, sandy foraminiferal biomicrite and sandy biomicrite. Silt-size zoned dolomite rhombohedra form up to 30% …

The Structural Controls Of The Vale Rhinehart Buttes Complex, Vale Kgra, Malheur County, Oregon, John Timothy Doerr

Dissertations and Theses

The Vale KGRA is characterized by high heat flow, two to five times higher than the worldwide average, and by numerous hot springs. The hot springs are aligned along faults. This phenomena is typical of a Basin and Range type geothermal system. The hot geothermal fluids migrate upward along the more permeable, fault planes.

The rocks exposed in the Vale area are the Pliocene Chalk Butte formation and the Pleistocene beds of Captain Keeney Pass. Both units are composed of volcaniclastic siltstones, sandstones and conglomerates. The units are differentiated by color, texture and degree of lithification. About 200 meters of …

Biomarker Geochemistry Of The Miocene Monterey Formation, West San Joaquin Basin, California: Implications For Petroleum Generation, Michael A. Kruge

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Much of the Miocene Monterey Formation of California is rich in biogenic sediment, especially organic matter and silica. Because of the geologic structure, the Monterey in the subsurface near Lost Hills in the San Joaquin Basin forms a natural laboratory for the study of the diagenetic responses of these materials. Rocks of similar age and lithology are buried to depths ranging between 500 and 3500 m, and are thus exposed to a temperature range of 45–130°C. The diagenetic progression of silica from opal-A to opal-CT to microquartz is well-documented in Monterey burial history studies. However, diagenetic indicators need to be …

Dolomitization Of The Hatch Hill Arenites And The Burden Iron Ore, Peter Michael Hofmann

Geology Theses and Dissertations

The Taconic allochthon is a sequence of Cambrian or Precambrian to Ordovician rocks. It is composed of predominantly deep water argillaceous and subordinate arenaceous and calcareous rocks that were deposited on the continental rise and slope. During the Ordovician, sediments which were earlier deposited in the slope-rise environment were incorporated into the accretionary prism of an island arc that approached from the east, and subsequently overthrust the carbonate platform.
The Hatch Hill Formation is part of the Taconic sequence. It consists of dominantly black-gray slates, minor amounts of sandstones and carbonates. Previous workers have recognized the presence of dolomite and …

Late Prehistoric And Protohistoric Large Mammal Zoogeography Of Virginia, Robert K. Rose

Biological Sciences Faculty Publications

Evidence derived from18late prehistoric (middle and late Woodland Period) archeological sites, from several early historical accounts, and from the current understanding of the distribution of Virginia mammals indicates that the large mammal fauna of the Commonwealth has not changed substantially within the past 4,000 yrs. Some species (e.g., bison, elk, timber wolf, and mountain lion) have been extirpated since the settlement of Virginia by Europeans; some previously extirpated species (e.g., porcupine, coyote, and beaver) have been naturally or artificially reintroduced during the historical period, and others (e.g., woodchuck and red fox) probably have expanded their distributions as a result of …

Contaminant Migration Of Oil-And-Gas Drilling Fluids Within The Glaciated Sediments Of North-Central North Dakota, William A. Beal

Theses and Dissertations

A common practice during oil and gas well-site reclamation in North Dakota is to bury the drilling muds in shallow trenches near the borehole. These muds are saltwater based (between 100,000 and 300,000 mg/L of NaCl) and can contain high concentrations of chromium, lead, and other. toxic trace metals.

Two reclaimed oil and gas well sites were chosen for study in north-central North Dakota: the Winderl site in southeastern Renville County, and the Fossum site in west-central Bottineau County. The Winderl oil well was drilled in 1959, and the drilling fluids were disposed of in a shallow pit excavated in …

Origin And Stratigraphy Of Holocene Sediments, Souris And Des Lacs Glacial-Lake Spillways, North-Central North Dakota, William M. Boettger

Theses and Dissertations

In the past few years, a new interpretation of the formation of the Souris and Des Lacs glacial-lake spillways has been proposed. Now, based on geomorphological evidence, it is concluded that the Souris and Des Lacs Valleys were formed by massive glacial-lake outburst floods at the end of the late Wisconsinan deglaciation. Five phases of drainage have been recognized with the first forming the Des Lacs Valley and the other four associated with drainage in the Souris Valley from different proglacial lakes in Canada. The last of these floods down the Souris Valley was the most erosive.

This study is …

Conodont Biostratigraphy Of The Bakken And Lower Lodgepole Formations (Devonian And Mississippian), Williston Basin, North Dakota, Timothy P. Huber

Theses and Dissertations

Fourteen cores were sampled and processed, and conodonts obtained were used in the biozonation of the Bakken and basal Lodgepole Formations in the Williston Basin in North Dakota. The Bakken Formation of Devonian and Mississippian age and the Lodgepole Formation, entirely of Mississippian age, are subsurface units in North Dakota. The Bakken Formation (44 metres thick) consists of, in ascending order: a lower, dark, organic shale; a middle calcareous siltstone that is divisible into three lithic units; and an upper, dark, indurated, organic shale. The Lodgepole Formation (160 to 260 metres thick) is an argillaceous, fossiliferous limestone near the Basin …

Theses and Dissertations

The Upper Cretaceous Niobrara Formation in eastern North Dakota consists of calcareous shales, chalks, and shaly chalks. The formation was studied from surface exposures, cores, and well logs. The Niobrara is 62 feet (19m) to 272 feet (83 m) and is thickest to the northeast, in a central linear area, and to the southwest. In a northern area, it was divided into a lower, calcareous shale member, and an upper, chalky member. In a.southern area, five stratigraphic units were recognized, in ascending order: a lower shaly chalk, a shale, a middle shaly chalk, a chalk, and an upper shaly chalk. …

Depositional History And Diagenesis Of The Upper Mission Canyon And Lower Charles Formations (Mississippian), Billings County, North Dakota, Randall A. Stephens

Theses and Dissertations

The upper Mission Canyon and lower Charles Formations of the Madison Group (Mississippian) in central Billings County, North Dakota respectively consist of interbedded limestones and dolostones, and anhydrite. Study of these rocks was limited to Big Stick and T.R. Fields, located on the Billings Anticline, central Williston Basin.

Detailed examinations of cores from a 166 ft (51 m) section within the upper Mission Canyon and lower Charles Formations resulted in the identification of seven lithotypes: echinoderm wackestone-packstone, dolomudstone, dolomitic echinoderm wackestone, grainstone, skeletalpeloidal carbonate, laminated carbonate, and anhydrite. The stratigraphic distribution of lithotypes is consistent throughout the study area.

The Effects Of Fly Ash And Flue-Gas Desulfurization Wastes On Groundwater Quality In A Reclaimed Lignite Strip Mine Disposal Site, Frank W. Beaver

Theses and Dissertations

Coal conversion wastes were generated at a lignite-coal-fired, steam-electric power station near Center, North Dakota, and were buried in unsaturated and saturated settings within the nearby stripmine, typical of settings used by the industry. The study ran for 8 years beginning in 1978. Approximately 240 piezometers were used for collecting groundwater level and groundwater chemistry data in the saturated zone. Pressure-vacuum lysimeters were installed to sample the unsaturated zone. Interstitial water was extracted from Shelby tube and auger samples at otherwise uninstrumented points.

More than 15,000 water-level recordings allowed precise definition of groundwater flow and occurrence at the study site. …

Shoreline Recession: Past, Present, And Future, Lake Sakakawea, North Dakota, Brian S. Sandberg

Theses and Dissertations

Shoreline erosion is a major problem at Lake Sakakawea, North Dakota. Instrumentation along the eastern shore was initiated in 1983 to measure shoreline recession and determine the processes responsible, with the ultimate goal being the development of a relatively simple equation to predict the rate of recession which is better than the model currently used by the U.S. Army Corps of Engineers.

For the twenty stations, the present rate of recession ranges from 0.2 to 4.3 m/y. Approximately 78 percent of the yearly recession occurs during the warm months (May-October) due to wave erosion. Erosion over the cold months occurs …

Deflation Basin Stratigraphy: Southwestern North Dakota, Robert E. Seidel

Theses and Dissertations

The goal of this study was the determination of a similar depositional sequence for sediments from a number of shallow basins in southwestern North Dakota and the comparison of this sequence with other work either in the area or in similar geographic environments.

Samples were obtained by augering, coring, and trenching selected basins. They were analyzed by means of: core description; detailed texture analyses on selected cores by sieve, pipette, and SediGraph techniques; and mineralogy by x-ray diffraction. Computer analyses were used to characterize grain-size distributions and to correlate texture and mineralogy by cross-association.

The results of the study verified …
