Stratigraphy And History Of The Sakakawea Sequence, South-Central North Dakota, William B. Bickley Jr.

Theses and Dissertations

The Sakakawea Sequence (Pleistocene) in North Dakota contains six formations that make up the Coleharbor Group (Pleistocene). The Braddock Formation (Wisconsinan) is mainly glacial sediment. The Emmons Formation (late Wisconsinan) is mainly glacial sediment. The Four Bears Formation (Wisconsinan) is mainly either fluvial or lacustrine sediment. The Coteau Formation (Holocene) is mostly fluvial, colluvial, or slough sediment. The Denbigh Formation (Holocene) is mostly eolian sediment. The Oahe Formation (late Wisconsinan and Holocene) is mostly eolian sediment (loess) The Oahe Formation is divided into three members: the Mallard Island (late Wisconsinan), Aggie Brown (latest Wisconsinan to earliest Holocene), and Riverdale (middle …

Black Magnetic Spherules From The Glacial And Sea Ice Of Fletcher's Ice Island (T-3), Richard Scattolini

Theses and Dissertations

Black magnetic spherules are particles which can be derived by ablationary processes from cosmic sources. Spherules from both the glacial ice and sea ice of Fletcher's Ice Island (T-3) were studied to determine their size distribution, sedimentation rates, and other parameters. The results were examined and shown to be similar to those of other researchers' work elsewhere.

Calculated sedimentation rates for glacial ice spherules, extrapolated for the entire earth's surface, range from 1.1 x 10⁴ to 1.1 x 10⁵ metric tons per year. Calculated sedimentation rates for sea ice spherules range from 5.0 x 10³ to 1.6 x 10⁵ metric …

Groundwater Of The Spiritwood Lake Area, Stutsman County, North Dakota, Frank J. Schulte

Theses and Dissertations

The Spiritwood Lake study area is in a generally undulating to rolling glacial plain 17 miles north and east of Jamestown, North Dakota. Spiritwood Lake is about 50 feet below the surface of the bedrock plain in a former melt-water channel. In the study area, glacial drift unconformably overlies the Pierre Shale, the youngest pre-Pleistocene sediment. The boundary between the two units is marked by a zone of shattered Pierre Shale. The top of this shattered zone forms a plain of moderate relief which probably was the preglacial surface of the study area.

Two large valleys can be distinguished in …

Applied Geology Of The Bismarck-Mandan Area, North Dakota, Gerald H. Groenewold

Theses and Dissertations

The Bismarck-Mandan area includes about 350 square miles located along both sides of' the Missouri River in south-central North Dakota. The area can be divided into two major physiographic divisions: the broad Missouri River floodplain and the nearly flat uplands which are dissected by minor streams. Geologic units in the area include Upper Cretaceous and lower Tertiary sandstone, siltstone, and shale and Quaternary sand, silt, clay, and gravel.

Expansion of residential areas around the cities of Bismarck and Mandan results in conflicts in land-use between agricultural, urban, and resource development. This study consists of detailed geologic maps and a series …

Septic Tank Nutrients In Groundwater Entering Lake Sallie, Minnesota, David Robert Lee

Theses and Dissertations

The nutrient contribution of septic tanks to a lake was evaluated at Lake Sallie, in glacial outwash terrain of northwestern Minnesota. Groundwater entering the lake was collected by covering 0.258 m2 of lake bed with a bottomless cylinder vented to deflated plastic bag. Inflow velocity ranged from 0.01 to 2.5 micrometers per-second along 30% of the lakeshore. Groundwater inflow along an 800 m segment of shore amounted to 4.50 x 105 m3/year, and was uniformly distributed along the shore, but decreased exponentially away from shore.

Effluent from a heavily-used lakeside septic tank fanned out along the surface of the water …

Geology Of Southern Nelson County, North Dakota, Roger J. Reede

Theses and Dissertations

Southern Nelson County occupies 576 square miles in northeastern North Dakota (Twps. 149-152 N., Rgs. 57-62 W.). Its surface is mantled with glacial drift resting unconformably on the Cretaceous Pierre Shale, which is exposed along the Sheyenne River Valley and the Stump Lake Basin. The entire mantle of glacial drift is part of the Coleharbor Formation, which, in southern Nelson County, averages 45 feet thick with a maximum thickness over 200 feet. Drill-hole data and missile site excavations provide good evidence for the existence of multiple drift sheets, including layers of till separated by more than 25 feet of outwash, …

The Mio-Eugeosynclinal Thrust Interface And Related Petroleum Implications In The Sason-Baykan Area, Southeast Turkey, Ismail Özkaya

Doctoral Dissertations

"A detailed investigation of the stratigraphy, structure and petroleum geology of the Sason-Baykan region in 600 square km area of the thrust belt of southeast Turkey was completed at a scale 1: 25 000. Geosynclinal sediments within the area were redated.

Results of field study indicate a massive plate of metamorphic rocks and crystalline limestones was thrust southward over geosynclinals sediments. These in turn were thrust over the southern marginal basin deposits. A stratigraphic sequence of the allochthonous geosynclinals sediments was reconstructed and correlated with the autochthonous Tertiary section. Contrary to earlier views the allochthonous sediments and accompanying igneous rocks …

Wall Rock Geochemistry Of The Chester Vein, Sunshine Mine, Kellogg, Idaho, Nicholas Howard Tibbs

Doctoral Dissertations

"The Chester vein has been the major source of ore from the Sunshine mine, largest single producer of silver in the world. 425 samples of quartzite and argillite wall rocks were collected in 13 traverses across this vein on the 4400, 4600, and 4800 mining levels. These samples were analyzed for aluminum, magnesium, calcium, sodium, potassium, manganese, iron, lead, copper, and zinc by atomic absorption spectroscopy, and for silicon and sulfur by x-ray emission spectroscopy. Element distribution plots, linear correlation coefficient matrices, varimax factor analysis, and cluster analysis were employed to determine the geochemical processes that occurred in the wall …

Precambrian Geology Of The Central Nacimiento Mountains, Sandoval County, New Mexico, Kent Richard Reed

Earth and Planetary Sciences ETDs

The oldest Precambrian rocks in the area of study are represented by abundant inclusions and schlieren of horn­blendite, plagioclase-hornblende schist, and plagioclase-­hornblende-biotite schist. These inclusions are remnants of a pre-batholithic metamorphic terrane.

The next oldest, and dominant rock in the central Nacimiento Mountains is gneiss that ranges in composition from quartz monzonite to granodiorite. Where strongly sheared, the rock is microcline-biotite-quartz-plagioclase schist. Gradational zones of schist within the gneiss were mapped separately. The gneiss and the schist are cut by metamor­phosed spessartite dikes and by leucocratic dikes of various textures and compositions.

Intruding the gneiss in the southeastern part of …

Gravity Investigations Over A Salt Structure Near Lübbecke, Northern Germany, Reinhard K. Frohlich

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

A detailed gravity survey was conducted parallel to the “Wiehengebirge” northwest of Minden in Northern Germany. The survey localized between Liibbecke and Levern a salt deposit, which is known as “Münder Mergel” salt of the Upper Jurassic. The salt deposit forms a cylindrical structure with an axis striking NWW. With a deep drill hole detailed interpretation was possible using the polygon method of TALWANI, WORZEL and LANDISMAN [1959], The section shapes of salt bodies under eight profiles show asymmetrical figures of two salt units. Both increase in thickness strongly to the northeast, where the salt is interrupted by a fault …

Geophysical And Geological Analysis Of A Fault-Like Linearity In The Lower Clackamas River Area, Clackamas County, Oregon, Ronald Jay Schmela

Dissertations and Theses

A fault-like linearity along the lower Clackamas River is evaluated by analysis of physiographic and structural alignments, geological relationships, and by gravity and magnetic data. The study has resulted in the verification of a structural feature extending along the Clackamas River and the eastern front of the Portland Hills.

Physiographic alignments were examined in twelve 15 minute and two 7-1/2 minute quadrangle maps. A significant northeasterly morphologic trend, N. 20⁰ W. and N. 40° W., and other secondary trends, namely, the N-S, E-W, and N. 50-60° E., has developed in the Portland area. The consistent northwest trend is observed throughout …

Geology Of The Rammel Mountain Area, Teton County, Wyoming, David W. Love

Earth and Planetary Sciences ETDs

The Rammel Mountain area, on the west side of the Teton Range, Wyoming, includes Precambrian metamorphic and igneous rocks; Paleozoic sandstone, shale, dolomite and limestone; and Cenozoic conglomerate, agglomerate and breccia, ash-flow tuffs and glacial deposits.

The Precambrian layered gneiss, granitic gneiss and migmatite have undergone at least two episodes of deformation and metamorphism in the sillimanite-cordierite-muscovite-almandine subfacies of the Abukuma-type facies series prior to the emplacement of quartz monzonite. Dia-base dikes, quartz-epidote and epidote veins transect these earlier rocks.

The Cambrian-Mississippian shelf-facies rocks were folded, faulted and eroded to a plain in Late Cretaceous time and were buried by …

Structure And Stratigraphy Of The Florida Mountains, Luna County, New Mexico., Lonnie Leroy Corbitt

Earth and Planetary Sciences ETDs

Precambrian rocks in the Florida Mountains have a long and complex history of orogeny and epeirogeny. The oldest recorded event is regional metamorphism (amphibolite facies) of sedimentary and igneous rocks which are intruded by granite. Following a long period of erosion, diamictite was deposited on a deeply weathered surface of igneous and metamorphic rocks.

At least 3,000 feet of Paleozoic strata is preserved above the Precambrian rock1s. The Paleozoic strata are mostly shelf carbonates; the Bliss Formation and the Devonian Percha Shale are the only major Paleozoic elastic units present. From Cambrian through Mississippian time the Florida Mountains area was …

Arctic Ecology: A Decade Of Experience, John F. Schindler

UMR Journal -- V. H. McNutt Colloquium Series

A quick glance at the title of this presentation and the reader braces himself for another antipollution or “save-the-sod” type of discourse that has become so popular these days. I do not wish to detract from the importance or the need for such efforts but I would like to address myself to the the broader meaning of the term.

Ecology--the word comes from the Greek root “oikos” which means house or household. What I’d like to do is to tell you about this “house” I’ve been living in for the past 10 years.

The Environmental Challenges Facing Taps, A. V. Cardin

UMR Journal -- V. H. McNutt Colloquium Series

Before the potential benefits of the recent oil discoveries on the North Slope of Alaska can be realized, the oil must be transported to refining and marketing areas. The Alyeska Pipeline Service Company has the responsibility for the first step in this transportation—to design and construct the Trans Alaska Pipeline System. We will pipe the oil from the discovery areas near Prudhoe Bay to an ice-free, deep-sea tanker loading terminal at Valdez of the South Coast of Alaska. From Valdez the oil will be transported to the West Coast by tankers. This is the most feasible system of a number …

The Environmental Challenges Of Alaskan Mineral Development, Earl T. Hayes

UMR Journal -- V. H. McNutt Colloquium Series

To meet the challenges and to develop Alaska as a source of mineral and fuel resources that are essential to all of us, we must conduct the research and planning necessary to see that the environment is not abused. We cannot allow ourselves the luxury of thinking that we alone know what is best for Alaska. We must strive for cooperation -- cooperation between government and industry; between Federal and State governments; between the doer and the dreamer; and between the engineer and the ecologist. Remember, the quality of what we do today will determine the quality of Alaska in …

Mineral Potential Of Arctic Canada, R. G. Mccrossan, R. M. Procter

UMR Journal -- V. H. McNutt Colloquium Series

Canada is on the threshold of a major new phase in the development of its Arctic resources. The Prudhoe Bay discovery triggered a boom in northern petroleum exploration that is just getting into high gear this year. Mining activity also has greatly expanded in the last few years with some 73 active exploration programs underway and several large new mines just coming into production. The size of these ventures is indicated by ore reserves of two lead-zinc mines to the value of 900 million dollars at Pine Point in southern Northwest Territories, and 1.2 billion dollars at the Anvil property …

Arctic Pipelining -- Tough, Costly, But Feasible, William H. Pearn

UMR Journal -- V. H. McNutt Colloquium Series

The development of vitally important Arctic petroleum resources presents new and interesting challenges. Although the answers to some questions will undoubtedly undoubtedly go unresolved until considerable operating experience has accrued, we can improve our present insight through an awareness of the work performed by others under similar conditions. This presentation focuses on Soviet pipelining experience in arctic and subarctic regions of Siberia.

Drilling Problems Associated With Arctic Minerals, Robert L. Parker

UMR Journal -- V. H. McNutt Colloquium Series

With major involvements in Alaska, the experience gained from these operations reflect the success of talented personnel in meeting the challenges of climate, equipment, logistics, perma-frost, etc. Real concern stems from present delays in the Arctic program due to financing involved as well as increasing dependency of the United States upon these reserves in today’s market and supply situation.

Arctic Oil And The S.S. Manhattan, Russell H. Venn

UMR Journal -- V. H. McNutt Colloquium Series

The discovery of oil on Alaska’s North Slope in 1968 not only focused attention on that remote part of our world, it set the stage for one of the most exciting and significant scientific expeditions of our time—the voyage of the ice breaking tanker SS Manhattan through the Northwest Passage.

In the space available I would like to discuss with you that historic expedition, how it came to be, and comment on the results, as we see them.

Oil And Gas Reserves In The Siberian Shelf, A. J. Eardley

UMR Journal -- V. H. McNutt Colloquium Series

The Arctic region must be the world’s largest storehouse of liquid and gaseous hydrocarbons, and the vast Siberian region, both “on land” and “off shore” must be considered with envy by the free-world’s geologists for its oil and gas potential. It is here estimated that the off shore continental shelf of U.S.S.R. Siberia contains a reserve of 200 billion barrels of oil and 500 trillion cut. ft. of gas. These very approximate figures come from meager data obtained from the literature on oil and gas discoveries in the Siberian Arctic, the basin location of these discoveries, and the projection of …

The Role Of The Independent In Alaska's Mineral Development, D. L. Simasko

UMR Journal -- V. H. McNutt Colloquium Series

In 68 years of oil industry history in Alaska, the independent has already played a substantial role. Eighty-three independent oil companies or operators have participated in drilling 82 exploratory wells or stratigraphic tests. Their activities extended from the discovery of first commercial oil at Katalla in 1902, to the extension of the Prudhoe Bay field in 1970. The success ratio for wildcat wells in Alaska is considerably higher than “outside,” and fields have all been major in statute, thereby reducing the cost per barrel of finding oil.

The most immediate deterrent to the success of the independent in Alaska is …

Maintenance And Operation Of Facilities And Equipment In The Arctic, Charles C. Norris, Charles W. Kelley, Carroll C. Livingston

UMR Journal -- V. H. McNutt Colloquium Series

This has been but a short sketch of a few of the problems attached to living and working in the Arctic. Much has been learned about this remote and hostile area of the world; there is much more knowledge and experience required, as has been demonstrated by the controversy surrounding the routing and construction of the Trans-Alaska Pipeline. Man’s progress depends not only on means for his survival, but also on deep ecological considerations and solid engineering.--Conclusion.

The Alaska Business Community's View Of The Development Of Alaska, William H. Scott

UMR Journal -- V. H. McNutt Colloquium Series

America has discovered Alaska!! Or maybe that’s just the way it seems to us Alaskans. Even though Secretary of State Seward bought the Great Land (that’s what Alaska means in native tongue) more than a hundred years ago, very little of its nature has drifted down to the “Lower 48”. That is until the great oil reserves were discovered on the now-famous North Slope. Only then was the fact of Alaska’s mineral wealth translated into something other than very general admissions that Alaska was the natural resource storehouse of the United States. Now one would naturally conclude that the Prudhoe …
