Hydrogeology Of The Hillsboro Landfill, Hillsboro, North Dakota, Jeffrey D. Maletzke
Hydrogeology Of The Hillsboro Landfill, Hillsboro, North Dakota, Jeffrey D. Maletzke
Theses and Dissertations
Landfills are the primary means for land disposal of solid wastes, and as such, they represent potential sources of groundwater contamination. This potential for contamination is exemplified by the Hillsboro landfill, which was emplaced above the Hillsboro aquifer, within permeable surface materials, and under shallow water-table conditions. Burial of refuse in trenches 15-feet (4.57 m) deep ensure that at least portions of the refuse are below the water table, which varied from 5.4 to 13.2 feet (1.7 to 4.0 m) below the surface. Concern over these factors led to the present study.
Subsurface conditions were investigated by electrical, earth-resistivity surveying. …
Macropaleontology Of The Gunn Member, Stony Mountain Formation (Upper Ordovician), Manitoba And North Dakota, Frederick K. Lobdell
Macropaleontology Of The Gunn Member, Stony Mountain Formation (Upper Ordovician), Manitoba And North Dakota, Frederick K. Lobdell
Theses and Dissertations
The Gunn Member of the Stony Mountain Formation has long been known to contain an abundant and diverse fauna. This study was undertaken to identify and describe the macrofauna of the Gunn Member in the subsurface of North Dakota, previously neglected.
As a necessary first step, collections of fossils from outcrop were examined and identified. With the outcrop fauna serving as a reference collection, twenty cores from the North Dakota subsurface were examined, described, and their fossils sampled. Fossil and sediment samples were washed and sieved and the residues were picked for microscopic representatives of phyla usually considered to be …
Sedimentology And Stratigraphy Of Glacial Lake Souris, North Dakota: Effects Of A Glacial-Lake Outburst, Mark L. Lord
Sedimentology And Stratigraphy Of Glacial Lake Souris, North Dakota: Effects Of A Glacial-Lake Outburst, Mark L. Lord
Theses and Dissertations
Glacial-lake outbursts commonly occurred along the southern margin of the Laurentide Ice Sheet as ice-marginal lakes suddenly drained. These outbursts released huge volumes of water with tremendous erosive potential, forming large trench-shape channels. Although glacial-lake spillways have been studied in detail, the effects of outbursts on downstream lakes have not. The purpose of this study was to demonstrate the effects of the Glacial Lake Regina outburst on the lake that received the flows, Glacial Lake Souris.
Glacial Lake Souris, located in what is now North Dakota, was inundated by about 74 km3 of water carrying 25 km3 of sediment from …
Stratigraphy And Depositional History Of The Deadwood Formation (Upper Cambrian And Lower Ordovician), Williston Basin, North Dakota, Douglas B. Anderson
Stratigraphy And Depositional History Of The Deadwood Formation (Upper Cambrian And Lower Ordovician), Williston Basin, North Dakota, Douglas B. Anderson
Theses and Dissertations
Based on gamma-ray characteristics, the Deadwood Formation is divided into six informal, attribute-defined units, members A through F. Members A and Bare Late Cambrian in age; members C through Fare Early Ordovician in age. The type section of the Deadwood, in the northern Black Hills, is dominated by Upper Cambrian strata. Much thicker Lower Ordovician rocks occur in the deeper portion of the Williston Basin.
The Deadwood comprises the Sauk sequence and represents the initial Paleozoic transgression or the seas on the North American craton. Eight smaller-scale transgressive-regressive events occurred on the craton during the Late Cambrian and the Early …
Thermal History Model Of The Williston Basin, Yue-Chain Huang
Thermal History Model Of The Williston Basin, Yue-Chain Huang
Theses and Dissertations
The factors that affect the subsurface temperature of a sedimentary basin were investigated by empirical and analytical methods. A review of thermal-mechanical models suggests that the Williston Basin was formed by more than one mechanism. The Williston Basin may have been initiated by a thermal event followed by thermo-flexural or phase transition subsidence.
The heat that initiated the formation of the Basin was significant to the thermal history of the Basin at its very beginning stage. However, most of the anomalous heat would have dissipated before the deposition of Bakken Formation 363 Ma ago. The heat flow history of the …
Characterization And Utilization Of High- And Low-Sodium Lignite Of The Beulah-Zap Bed (Paleocene), Indian Head Mine, Southwestern North Dakota, Gale G. Mayer
Theses and Dissertations
A study of high- and low-sodium lignite of the Beulah-Zap bed sampled at the Indian Head Mine, Pit 11 and 12, respectively, in Mercer County, North Dakota and fly ash derived from utilization tests on the lignite, indicates the fly-ash composition and related utilization potential can be correlated to coal geochemistry.
Average lithotype abundances for each of the sampling sites were estimated to be vitrain 50%, attritus 45%, and fusain 5%. Attritus occurs more frequently in the upper part and vitrain in the middle and lower parts of the seam. Maceral groups, identified microscopically, were (in order of decreasing abundance): …
Pressure-Solution Features Of The Birdbear Formation (Devonian), Williston Basin, North Dakota, James C. Collier
Pressure-Solution Features Of The Birdbear Formation (Devonian), Williston Basin, North Dakota, James C. Collier
Theses and Dissertations
Pressure-solution features of the Birdbear Formation (Devonian), Williston Basin, North Dakota were the subject of this study. In the area studied, the Birdbear Formation is primarily a limestone with mud-rich textures. The investigation contained three principal phases: 1) a study of the parameters influencing the size and shape of the pressure-solution response, 2) the process of reactate dolomite formation and its relation to calcite neornorphism, and 3) the relation of neomorphism to pressure solution.
The principal pressure-solution response types are stylolites and solution seams. Stylolites are pressuresolution seams with a tooth-and-socket, serrated shape. Pressure-solution seams are gently undulating to smooth …
Major And Trace Element Characterization And Correlation Of The Sentinel Butte Ash/Bentonite (Paleocene), Mckenzie County, North Dakota, Richard A. Larsen
Major And Trace Element Characterization And Correlation Of The Sentinel Butte Ash/Bentonite (Paleocene), Mckenzie County, North Dakota, Richard A. Larsen
Theses and Dissertations
The Sentinel Butte ash/bentonite has been used for stratigraphic correlation in and around the North Unit of Theodore Roosevelt National Park in western North Dakota primarily by tracing it along the escarpments of the Little Missouri River. The purpose of this study was to determine the geochemical fingerprint for the Sentinel Butte ash/bentonite, and use this fingerprint to assess the correlation value of this and other terrestrial bentonites. Mapping enlarged the known geographic distribution of this unit and provided an insight into its diagenetic history.
Samples from thirty randomly chosen sites and fifteen grab sites were used to evaluate the …
Proterozoic Structures In North-Central North Dakota: A Gravity Study, Kathryn C. Luther
Proterozoic Structures In North-Central North Dakota: A Gravity Study, Kathryn C. Luther
Theses and Dissertations
The purpose of this study was to determine the structure of the contact between the Superior Craton and the Trans-Hudson orogenic belt in north-central North Dakota between latitude 48 and 49 degrees north and longitude 100 and 102 degrees west, using gravity modeling. Major structural and geochronologic boundaries beneath the eastern flank of the Williston Basin in North Dakota and southern Canada appear as coherent patterns on a Bouguer gravity map.
The contribution of the Phanerozoic overburden (density assumed to be 2 . 48 g cm- 3 ) to the gravity signal, was removed, leaving residual gravity anomalies due to …
Deposition And Diagenesis Of A Portion Of The Frobisher-Alida Interval (Mississippian Madison Group), Wiley Field, North Dakota, Mark R. Luther
Deposition And Diagenesis Of A Portion Of The Frobisher-Alida Interval (Mississippian Madison Group), Wiley Field, North Dakota, Mark R. Luther
Theses and Dissertations
This study focused on the Frobisher-Alida interval, in particular, the Glenburn bed or the Mississippian Mission canyon Formation. Wireline logs and cores from closely spaced wells in, and adjacent to, the Wiley Field, Williston Basin, North Dakota were examined. Information derived from the wireline logs was used to construct several maps which show that there was little or no topographic relief or slope in the study area during deposition or the Glenburn bed. In addition, the maps show that structural derormation occurred subsequent to deposition or the Frobisher-Alida interval.
Six distinct lithoracies were recognized in cores or the Glenburn bed …
