A Geomagnetic Survey Of Pembina, Grand Forks, And Eastern Walsh Counties, North Dakota, Howard E. Okland

Theses and Dissertations

From August, 1977, to March, 1978, total field geomagnetic readings were taken at 948 sites in the following counties in North Dakota: Pembina County, Grand Forks County, and Walsh County east of 98°W. longitude. The field data was contoured by computer using the SYMAP commercial computer program. Nine major and several minor magnetic anomalies were discovered. Trends present on the aeromagnetic map of Minnesota continue westward into North Dakota. Limited bore hole data and the geomagnetic map suggest that the study area is underlain by Precatnbrian rocks of the Superior geologic province. The northernmost trend may indicate a western extension …

Petrology Of Sandstones From The Bullion Creek And Sentinel Butte Formations (Paleocene), Little Missouri Badlands, North Dakota, Mark A. Steiner

Theses and Dissertations

The mineralogy and petrology of sandstones of the Paleocene Bullion Creek and Sentinel Butte Formations were studied from exposures in the Little Missouri River Badlands in Billings, Golden Valley, and McKenzie Counties, North Dakota. Field work was conducted in the summer of 1977. Stratigraphic sections were measured and described from eight localities. Sandstones were sampled at 47 levels, and three samples were collected from each level. Fifty-one samples were collected from the Bullion Creek Formation and 90 from the Sentinel Butte Formation.

Thin-sections were prepared from plastic grain-mount blocks containing disaggregated sand grains, and 200 points per thin-section were counted, …

Geology Of The Lucea Inlier, Western Jamaica, Jack Grippi

Geology Theses and Dissertations

The Lucea Inlier exposes a Santonian to Campanian 4 km + thick sequence of shale-siltstone, resedimented volcaniclastics, lenses of shallow-water limestone, micritic limestone, pebbly mudstone and sandy pebble to boulder conglomerate. Clastics were deposited by a variety of gravity flow mechanisms. Petrographically sandstones are lithic or feldspathic arenites and contain only very small amounts of detrital quartz. Structurally the inlier is characterized by simple, open, east-west trending folds. A spaced, vertical axial-planar cleavage is developed in shales and fine siltstones. Two major east-west trending left-lateral fault zones, the Fat Hog Quarter and Maryland faults, cut the inlier into three blocks, …

Sedimentology Of The Hannibal Formation In Northeastern Missouri And Western Illinois, Michael Harry Deming

Masters Theses

"The Hannibal Formation (Kinderhookian) occurring in northeastern Missouri and western Illinois is a fine-grained, terrigenous, sedimentary unit which can be divided into an upper and a lower portion, based on lithology. The upper portion consists of alternating coarse and argillaceous, fine siltstone units, while the lower portion consists of a silty mudstone with an occasional thin siltstone unit. At the extreme western margin of the formation, near where the Hannibal almost pinches out, the formation consists entirely of a silty claystone. Extending southward along the study area, the coarse siltstone units of the upper Hannibal become thinner, and eventually pinch …

Landsat Image Analysis Of Linears And Lineaments In The Tri-State District, Missouri-Oklahoma-Kansas, Solomon Hartley Toweh

Masters Theses

"Lineations within the Tri-State mining district are classified as megalineaments, lineaments and linears, based on length. One megalineament, 120 lineaments and 205 linears are identified on the LANDSAT imagery. In order of importance a dominant northeast set, northwest set, north-south set and east-west set are recognized. These range from 0.8 miles (1.3 km) to 68 miles (109.4 km) in length.

Major lineation trends spatially relate with trends of mined areas In the Picher field both northeast and northwest lineations generally parallel mined areas. In the Galena field ore and lineations trend northeast while in the Joplin and Duenweg-Webb City-Oronogo field …

The Rhame Bed (Slope Formation, Paleocene), A Silcrete And Deep Weathering Profile, In Southwestern North Dakota, Barbara D. Wehrfritz

Theses and Dissertations

The Rhame Bed is a unit at the top of the Slope Formation (for merly part of the "Ludlow Formation") in the Fort Union Group deposited during Paleocene time.

The Rhame Bed was mapped in western Slope County and north central Bowman County. The bed outcrops on the tops of buttes, at the present groJnd surface in large level areas, or in steep slopes. Although the bed is laterally discontinuous, it is a clearly mappable unit.

The Rhame Bed typically consists of two dominant lithologies: siliceous rock and white sediment. The siliceous rock is hard, gray, and made of silt-sized …

Depositional Systems Of The Sells And Cecil Sandstones, Atoka Formation (Pennsylvanian), Eastern Crawford And Western Franklin Counties, Arkansas, Chris A. Cardneaux

Journal of the Arkansas Academy of Science

The Cecil and Sells sandstones of the Atoka Formation (Pennsylvanian) were studied in the subsurface of eastern Crawford and western Franklin Counties. Sand of the Cecil sandstone was delivered to a high destructive, wave dominated delta southeast of Fort Smith and reworked laterally by longshore currents to form coastal barrier sands to the east. The Sells sandstone unit accumulated as a distributary channel system that bifurcates to the southeast and southwest. The interdistributary areas are characterized by immature sands interbedded with shales. These immature sands were deposited by crevasse splays and reworking of the distributary mouth bars by marine processes …

Stratigraphy Of The Lower Tertiary And Upper Cretaceous (?) Continental Strata In The Canyon Range, Juab County, Utah, James M. Stolle

Theses and Dissertations

The Canyon Range Formation (informal new name), formerly mapped as the Indianola Group within the Canyon Range, is divisible into two distinct, mappable units, A and B. Unit A is nearly all conglomerate strata, and conglomerate texture and sedimentary structures suggest an alluvial fan depositional environment. Precambrian and basal Cambrian quartzite clasts represent the erosional debris from the allochthonous Canyon Range thrust. Unit B is composed of interbedded fluvial sandstone and conglomerates with lacustrine limestones, commonly micritic and/or oncolitic. Conglomerate clasts indicate a Paleozoic carbonate provenance. Unit A, previously mapped as the Indianola, underlies Unit B and correlates with the …

The Paleontology And Biostratigraphy Of The Lower Ordovician Gasconade Formation Of Missouri, Bruce L. Stinchcomb

Doctoral Dissertations

"The biostratigraphy, paleoecology and paleontology of the Lower Ordovician Gasconade Formation in Missouri is reinvestigated in an attempt to solve problems that have arisen since the classic earlier studies by Ulrich, Bridge and others. Twelve faunal zones are established, many based on primitive mollusks which dominate the formation. The oldest of these, in the Van Buren Member, is the Hypseloaonus Zone. This is followed by a zone characterized by the primitive cephalopod Dakeoaeras then a zone dominated by the gastropod Sinuopea. These zones are succeeded by the Euomphalopsis, Matthevia and Ozarkina Zones which lie stratigraphically below the Cryptozoon Zone, …

Heat Flow And Heat Production Studies In North Dakota, Richard Scattoline

Theses and Dissertations

Thirty-one new heat flow determinations in North Dakota range from 0.6 to 1.9 HFU. The majority of heat flow measurements were completed for southwestern North Dakota.

Heat flow measurements were made in both oil and water wells. Heat production data from basement rocks when used in conjunction with nearby heat flow values indicate that only two of six sites may be considered to be similar to Basin and Range type of heat flow. One site occurs in southwestern North Dakota in a region west of 103° W where no heat flow value is less than 1.5 HFU. The other site …

A Petrochemical Characterization Of Certain Dsdp Subaqueous Basalts And Andesites From The Indian Ocean, John Lee Berkley

Earth and Planetary Sciences ETDs

Thirty-eight samples of Indian Ocean subaqueous basalt and andesite recovered by the Deep-Sea Drilling Program (DSDP) were analyzed by the following methods: (1) standard petrographic analysis, (2) electron microprobe analysis of major minerals, (3) bulk-rock analyses for major, minor, and trace elements, including eight rare earth elements (REE), and (4) determination of 87Sr/86Sr by mass spectroscopy. A varied suite of basement igneous rocks was studied, including (1) abyssal tholeiites, (2) ferrobasalts, (3) oceanic andesites, (4) transitional basalts (high-Al basalts), and (5) trachybasalts.

Texture, Fabric And Composition Of Fine-Grained Terrigenous Sediments From The Graneros Member Of The Mancos Shale, San Juan Basin, New Mexico, Anthony J. Skeryanc

Earth and Planetary Sciences ETDs

Petrography, scanning electron microscopy (SEM), porosity and permeability, radiography, x-ray diffraction (clay mineralogy), whole rock wet chemistry and organic analysis are used to examine the texture, fabric and composition of fine-grained terrigenous sediments from the Graneros Member of the Mancos Shale, San Juan Basin, New Mexico. Grain content is highly variable and determines the configuration of the fabric during compaction. A scale of the degree of parallel orientation is compared to grain content and reveals a decrease in parallelism with an increase in grain content. Grain content also affects permeability, thus controlling he degree of authigenic mineralization. Although clay composition …

The Parmo De Berlin, Colombia: A Study Of Water Resources In A Rural Andean Community, Daniel Bodo

Masters Theses & Specialist Projects

The condition of water resources in the rural Andean community of Berlin, Colombia, was explored for the purpose of future development in the area. Through investigation of water acquisition techniques, use, and water discharge methods, combined with analysis of chemical water quality tests, the overall pattern of water resources in the study area was revealed. Although the methods of acquiring water were not found to be especially damaging to water quality, the use, and more importantly, the methods of discharging waste water suggested a water resource base harboring certain questionable qualities. The quality of surface waters, as revealed through analysis …

Mineralogy, Petrology, And Geochemistry Of Some Lavas From Kohala Volcano, Hawaii, Steven Sherman Sibray

Earth and Planetary Sciences ETDs

Twelve samples from Kohala volcano, Hawaii, were selected for chemical analyses and electron microprobe study. Seven of the samples are from the Polulu volcanic series. Three of the samples are tholeiitic basalts, two are oceanites, and two are alkali olivine basalts transitional to hawaiite. The five samples from the Hawi volcanic series include one hawaiite, two mugearites, and two benmoreites. Electron microprobe study of the minerals in the basaltic matrix of the two oceanites reveal that one of the oceanites was derived from a tholeiitic magma while the other was derived from an alkalic magma. The alkalic oceanite matrix is …
