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 …

Estimates Of Maximum Past Overburden For The Pierre Shale, Hayes Area, South Dakota, Thomas L. Rice

Science and Mathematics Faculty Publications

The Pierre Shale of the Northern Great Plains area of the United State is an Upper Cretaceous shale which was deposited in a marine environment. Geotechnically, the shale has been classified as an overconsolidated clay-shale. In South Dakota the Pierre Shale crops out extensively in the central and western portions of the state.

In this study an investigation was conducted for the purpose of clarifying and examining the existence of a discrepancy between geotechnically and geologically derived estimates of maximum past overburden for the Pierre Shale at Hayes, South Dakota.

Depositional Environments And Diagenesis, Winnipegosis Formation (Middle Devonian), Williston Basin, North Dakota, Nancy A. Perrin

Theses and Dissertations

In the Williston Basin, the Winnipegosis Formation is the major carbonate unit of the initial transgressive-regressive pulse of the Kaskaskia sequence. Twenty-two lithofacies were identified by well-log, core, and thin-section studies of Winnipegosis rocks; these belong to seven environments of deposition which include deep basin, deep shelf, shallow shelf, reef, lagoon, tidal flat, and evaporite basin. The deposition of the Winnipegosis and Prairie Formations were inter-related and occurred during six episodes. Following a brief hiatus separating the underlying Ashern Formation from the Winnipegosis, a clear, quiet, shallow-marine environment became established in the North Dakota portion of the Elk Point Basin. …

The Geology And Structure Of The Canyon Creek-Church Mountain Area, North Cascades, Washington, Jeffrey T. (Jeffrey Thomas) Jones

WWU Graduate School Collection

Four major rock assemblages ranging from Precambrian to Lower Cretaceous occur in the Canyon Creek/Church Mountain area of northwestern Washington. Lithologic, structural, and fossil evidence were used to discriminate among the assemblages and to correlate them with the Chilliwack Group, the Nooksack Group, the Yellow Aster Complex, and a unit previously included in the Chilliwack Group, referred to here as the "chert/basalt unit." These assemblages were juxtaposed during middle Cretaceous tectonism along low angle and high angle faults. There is some evidence for additional structural deformation after the middle Cretaceous.

The Chilliwack Group, consisting of volcanic rocks, volcaniclastic rocks, and …

Depositional Environments And History Of The Winnipeg Group (Ordovician), Williston Basin, North Dakota, Stephen C. Thompson

Theses and Dissertations

The Winnipeg Group (Ordovician) in the Williston Basin, North Dakota, contains three formations. They are, in ascending order, the Black Island Formation, herein informally divided into lower and upper members, the Icebox Formation, and the Roughlock Formation. Strata of the Winnipeg Group (maximum thickness 400 ft., 122 m) represent the initial deposits of a Middle Ordovician craton-wide transgression. Throughout most of North Dakota, the Winnipeg is unconformably underlain by the Deadwood Formation (Upper Cambrian-Lower Ordovician) and conformably overlain by the Red River Formation (Upper Ordovician).

The strata of the lower member of the Black Island Formation consist of a red-bed …

Thermometry And Barometry Of Precambrian Orthogneisses And Related Rocks From The Minnesota River Valley, Southwestern Minnesota, Paula J. Leier

Undergraduate Theses and Senior Projects

Granulite facies metamorphism is reported to have occurred in the Granite Falls-Montivideo area of the Minnesota River Valley and a broader view of the valley is taken to determine the extent of granulite facies metamorphism. Pressures and temperatures of metamorphism were determined using two geothermometers and one geobarometer. Based upon two-feldspar and garnet-biotite thermometers, temperature of metamorphism is approximated at 600 °c. Metamorphic pressures based on the reaction cordierite= garnet+ quartz + sillimanite were probably between 4 and 6 Kbars. Based on barometry and thermometry, it is suggested the Algoman o rogeny (2600 m.y. ago) was at least upper amphibolite …

The Petrochemistry Of The Ankara Volcanics, Central Turkey, Jay A. Ach

Geology Theses and Dissertations

The Ankara volcanics comprise a small volcanic field immediately to the north of Ankara, Turkey. This volcanic field is composed of a mixture of flows, tuffs, and agglomerates, with the flows ranging in composition from high-K basaltic andesite to rhyolite. Dacitic flows are the most common. A potassium-argon date gives a Middle Eocene age of 42.0 ± 1.6 m.y. The volcanics unconformably overlie Paleozoic sediments of the "Cimmerian continent" to the south and Mesozoic rocks of the Ankara melange to the north.

Paleocene Coal-Bearing Sediments Of The Williston Basin, North Dakota : An Interaction Between Fluvial Systems And An Intracratonic Basin, Laramie M. Winczewski

Theses and Dissertations

Outcrop and test hole data for 225 sites in a 33,700-km² area of southwestern North Dakota were examined. Seven sedimentation intervals were identified for the Paleocene Bullion Creek and Sentinel Butte Formations. The intervals extend from the top of the Harmon coal (lower Bullion Creek) to the top of the Twin Buttes coal (upper Sentinel Butte). Each interval consists of medium and fine elastics underlying a persistent lignite coal, or some other lithology at the stratigraphic position of the coal. Clastics are finer-grained upwards within intervals and within both formations to the upper Sentinel Butte.

Sand-rich zones align northwest-southeast, …

Carbonate Bodies Within The Basal Swift Formation (Jurassic) Of Northwestern North Dakota, Tina M. Langtry

Theses and Dissertations

The carbonate bodies of the basal Swift Formation (Upper Jurassic) occur as anomalous deflections on a relatively uniform mechanical well log section. The areal distribution, stratigraphic relationships, and genesis of the carbonate bodies were determined by using the gamma ray log, the spontaneous-potential log, the resistivity log suite, and megascopic and microscopic core analysis.

The carbonate bodies of the basal Swift Formation are coarsening upward sequences composed of predominantly sand-sized, recrystallized mollusk grains. These grains were transported by strong bottom cur rents across the irregular sea floor of the shallow epicontinental Jurassic sea, and were deposited under agitated water conditions …

U-Pb Studies Of Zircon Cores And Overgrowths, And Monazite: Implications For Age And Petrogenesis Of The Northeastern Idaho Batholith, M. E. Bickford, R. B. Chase, B. K. Nelson, Robert Duncan Shuster, E. C. Arruda

Geography and Geology Faculty Publications

U/Pb isotopic studies of zircons, many containing xenocrystic cores with euhedral overgrowths, and monazite from igneous rocks and metasedimentary inclusions of the northeastern Idaho batholith yield linear arrays on concordia diagrams. We interpret these as mixing lines between an old component (cores) and a young component (overgrowths and zircons without cores). The lower intercept of such arrays with concordia may yield the minimum age of the rocks if the overgrowths and zircons without cores are discordant, or the crystallization age if they are concordant. Monazites yield apparently concordant ages either equal or less than the lower intercept zircon ages. The …

Mineralogy And Petrology Of Lava Flows (Tertiary-Quaternary) In Southeastern Idaho And At Black Mountain, Rich County, Utah, Barbara J. Puchy

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Lava flows of Tertiary-Quaternary age occur in Enoch Valley, Upper Valley, and Slug Valley in southeastern Idaho. The basalts in Upper Valley and Enoch Valley contain olivine (Fo₆₉ to Fo₃₇), plagioclase (An₆₂ to An₃₉), augite and Fe-Ti oxides. The lava in Slug Valley lacks plagioclase, but contains sanidine (Or₇₀ to Or₅₆) with a trace of biotite and amphibole, and thus, has been termed alkali trachyte.

Black Mountain, on the eastern side of Bear Lake, northeastern Utah, is capped by basalt. Minerals present include olivine (Fo₈₃ to Fo₇₂), plagioclase …

Geology For The Layman, James O. Staggs

Annual of the Arkansas Natural Resources Law Institute

The first thing that an individual must thoroughly understand, is that geology is not an exact science. This may be strange for a geologist to say, but it is very similar to the profession of law in that any set of data may be and is usually interpreted differently by individual lawyers. We geologist start with some known facts (sometime geological), make assumptions, and then intrepret into the unknown. It is this interpretation that separates a successful geologist from a geologist. A successful oil finding geologist is a geologist that has developed this interpretation of geological facts into an art. …
