Stratigraphic And Paleontologic Studies Of Paleocene And Oligocene Carbonate Facies Of The Eastern Gulf Coastal Plain, Jonathan Russel Bryan

Doctoral Dissertations

Shallow marine Paleogene carbonates of the Eastern Gulf Coastal Plain contain a variety of unique and largely undocumented facies. The Late Paleocene Salt Mountain Limestone of southwestern Alabama is a coral-algal-sponge buildup composed of large foram-algal packstone, algal bindstone, and sponge-coral bafflestone. Abundant coralline algae and a low diversity coral fauna are characteristic of Paleocene reefs, but sponges are rare in earliest Tertiary sediments. Their abundance in the Salt Mountain could indicate an opportunistic response of sponges as reef constructors after the extinction of rudist-coral communities in the Late Cretaceous.

Environmental Radiocesium In Subarctic And Arctic Alaska Following Chernobyl, M. Baskaran, J. J. Kelley, A. S. Naidu, D. F. Holleman

Environmental Science and Geology Faculty Research Publications

Radiocesium (¹³⁴ Cs and ¹³⁷ Cs) concentrations were measured in soil, plant and wildlife samples from subarctic to arctic Alaska. Concentrations of ¹³⁷ Cs ranged from below detectable or low levels in whale and fish samples to as high as 242 Bq/kg in lichen. For all potential human food items, the radiocesium concentrations measured in this study were below accepted permissible levels for human consumption. Chernobyl-derived radiocesium concentrations ranged from below detectable or low levels in all arctic samples (soil, sediment, lichen, whale, fish and caribou) to 32 Bq/kg in subarctic moss. Therefore the distribution and subsequent deposition of Chernobyl-derived …

Structural, Depositional, And Diagenetic Controls On Reservoir Development: St. Peter Sandstone, Newaygo County, Michigan, Mark S. Caldwell

Masters Theses

Enhanced reservoir quality in the Middle Ordovician St. Peter Sandstone is observed in gas bearing zones in wells located on domal structures. Geometry and degree of this enhanced porosity development is the result of the interplay of structural, depositional, and diagenetic controls. An integrated subsurface study of the Woodville/Goodwell field area was performed in order to document controls on hydrocarbon accumulation.

Recurrent structural growth of domal features throughout the Paleozoic is well documented by isopach mapping. Burial and thermal history studies indicate that hydrocarbons were generated in Ordovician aged source rocks during late Devonian to early Mississippian time, and accumulated …

The Sloan Sag: A Mid-Miocene Volcanotectonic Depression, North-Central Mccullough Mountains, Southern Nevada, Hayden L. Bridwell

UNLV Theses, Dissertations, Professional Papers, and Capstones

In the Hidden Valley area of the north-central McCullough Mountains, southern Nevada, mid-Miocene andesite and dacite domes, flows and pyroclastic units (the Sloan volcanics) partially fill a sag in the underlying Hidden Valley volcanics. The 13.5 km diameter sag formed during and/or after the eruption of the Sloan volcanics. Sagging was accommodated by a combination of movement on the McCullough Wash fault system, and subsidence into evacuated chambers.

Major, trace and rare-earth element geochemistry suggests that the rocks of the Sloan volcanics belong to four groups, each of which were produced by partial melting of chemically distinct sources. With the …

Trace Fossils Of Shallow Subtidal To Dunal Ichnofacies In Bahamian Quaternary Carbonates, H. Allen Curran, Brian White

Geosciences: Faculty Publications

Pleistocene and Holocene carbonate grainstones or calcarenites capping the islands of the Bahamas commonly contain distinctive animal and/or plant trace fossils. Three ichnocoenoses within the Skolithos and Psilonichnus ichnofacies are recognized in the transition from sediments deposited in the shallow shelf environment, commonly associated with coral reefs, to sediments of the coastal dune environment. Analog relationships between the trace fossils and modern tracemakers can be established in many cases, and this correspondence strengthens the interpretive model. Ophiomorpha

and Skolithos linearis characterize beds deposited in shallow shelf settings. Psilonich- nus upsilon, the fossil burrow of the ghost crab Ocypode quadrata …

Metamorphic Evidence For Tilt Of The Spuzzum Pluton – Diminished Basis For The Baja British-Columbia Concept, E. H. Brown, Russ R. Burmester

Geology Faculty Publications

To address the question of tilt versus translation as the mechanism responsible for discordance between paleomagnetic directions of Cretaceous plutons in the British Columbia Coast Plutonic Complex and the North American reference direction, metamorphic pressures around the margin of the Spuzzum pluton have been determined. Pressures are derived from microprobe analyses and evaluation of exchange equilibria in the assemblage garnet-biotite-plagioclase-aluminum silicate-quartz. Samples studied come from eight localities in the contact aureole around the pluton and encompass the area of a previous paleomagnetic study. The analyzed samples are coarse grained and exhibit textural features indicative of equilibrium crystallization following emplacement of …

The Geomorphology Of Alluvial Fan Deposits On The West Flank Of The Blue Ridge, Augusta County, Virginia, Debra Lynn Duffy

OES Theses and Dissertations

Large coalescing alluvial fans mantle the carbonate and shale formations west of the Blue Ridge mountains near Stuarts Draft, Virginia. Fan sediments are predominantly boulder and cobble gravels derived from the Antietam Quartzite, The fan complex consists of three alluvial units of significantly different ages. The surface of each fan unit was mapped using relative geomorphic position, soil color, clay content and thickness of Bt horizons, clast weathering, and degree of removal of depositional surfaces by stream incision. A five-category quartzite clast weathering scale developed for this study was very effective as a measure to distinguish map units. Stratigraphic data …

An Analysis Of Hydrogeologic Factors Affecting Aquifer Vulnerability In Southwestern Michigan, Steven E. Benton

Masters Theses

In southwestern Michigan aquifers are threatened by human activities. Parameter/factor weighting systems are used to rate aquifer vulnerability. Hydrogeologic factors affecting aquifer vulnerability were investigated in this study.

Well records, soil surveys, hydrogeologic reports, and partial chemical analyses were used to obtain data on the aquifers, soil types, glacial sediments, and types of contaminants. Data analysis included comparisons of means and medians, factor analysis, and Pearson and Spearman Correlation analysis.

The results indicate that the aquifers in Kalamazoo County are not protected. Depending on the type of glacial sediment, hydrogeologic factors that protect aquifers are clay thickness and the depth …

Fractures In The Jacobsville Sandstone And The Precambrian “W” Rocks In Eastern Marquette County, Michigan, Leonard Paul Belliveau

Masters Theses

The major fracture systems in the Jacobsville sandstone likely originated by reverse faulting on the Keweenaw fault and by glacially produced thrusting. Fracture orientations, apertures, and spacings are uniform in the Jacobsville sandstone and Lighthouse Point member of the Mona Schist, and are variable in the Lower member of the Mona schist and Compeau Creek gneiss. Fracture sets in the Compeau Creek gneiss exist in domains separated by metadiabase dikes. The metadiabase dikes relieved the strain produced by the Penokean orogeny by fracturing. Fractures present in inclusions, quartz veins, metadiabase and diabase dikes can be used to temporally evaluate the …

A Hydrogeochemical Characterization Of A Glacial-Drift Aquifer System In Southwest Michigan, Patrick G. Barrese

Masters Theses

A hydrogeochemical investigation of the Schoolcraft Aquifer, an unconfined, glacial-drift aquifer located in southwest Michigan, was undertaken to focus on three topics: (1) the geochemical definition of recharge and discharge zones both vertically and laterally along projected flow paths, (2) the description of the carbonate and redox chemical systems, and (3) groundwater degradation associated with excessive nitrate, ammonium, and chloride concentrations.

The results of the study were inconclusive in defining recharge and discharge zones; however, iron and alkalinity concentrations were identified as possible indices for recharge and discharge conditions. The carbonate analysis indicated that the aquifer is saturated with respect …

Hydrocarbon Potential Of The Kahramanmaraş And Elbi̇stan Areas, Yüksel Önem

Bulletin of the Mineral Research and Exploration

The Taurus mountains, which developed in the conjoining zone of the Anatolian and Arabian Plates, underwent a disruption between Bolkar mountain and Engizek mountain. This can be explained by the fact that the area was traversed and transformed by two major strike-sup faults situated at Mersin-east Bolkar mountain-Kayseri in the west and Antakya (Hatay)-Elazığ-Bingöl in the east, In fact, the east-west oriented 200 km. wide area, covering the Gulf of İskenderun and the northern pan of Adana, was compressed and deflected as far as the north of Sarız and the Arabian Plate was dislocated prior to the faulting and moved …

Basement Control On The Development Of Selected Michigan Basin Oil And Gas Fields As Constrained By Fabric Elements In Paleozoic Limestones, Robert Thomas Versical

Masters Theses

Hydrocarbon bearing structures in the Paleozoic section of the Michigan basin possess different structural styles and orientations. Quantification of the direction and magnitude of shortening strains by applying a calcite twin-strain analysis constrains the mechanisms by which these structures may have developed. The calcite twin-strain analysis and fracture orientations in Paleozoic rocks indicate that the mean direction of compression controlling structural development ranged from SE-NW to nearly E-W. This direction of compression nearly parallels the majority of structures in the basin, and provides insight into their origin.

The structural geometries of fields considered in this study can be explained by …

Facies Analysis And Diagenesis Of The Lower Engadine Group And The Manistique Group In Manistee, Mason And Oceana Counties, Michigan, Karen S. Mater

Masters Theses

Three lithofacies in the Lower Engadine Group, and four lithofacies in the Manistique Group were identified. Facies patterns suggest a transgression during deposition of the Manistique Group and Lower Engadine Group.

Environments of deposition were determined by analysis of facies found in the Lower Engadine and Manistique Groups using available cores, petrophysical logs, and well cuttings. The diagenetic sequence of events was identified using thin sections.

Diagenesis has greatly altered original fabric and porosity. Hydrocarbon accumulation in these units is dependent on facies distribution, diagenesis, and structural features.

Origins Of Low-Angle Normal Faults Along The West Side Of The Bear River Range In Northern Utah, Jon E. Brummer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This paper presents new interpretations of two normal-slip, low-angle faults near Smithfield and Richmond, Utah. The faults have previously been interpreted as landslides, gravity slides, slide blocks, and depositional contacts. Recent work in the Basin and Range province allows new interpretations concerning the origins of the low­-angle faults.

Working hypotheses used to interpret origins of the faults are classified as folded thrust fault, rotated high-angle normal fault, gravity slide, listric normal fault, and low-angle normal fault. Among these general categories are several subhypotheses. The evaluation of each hypothesis includes a description of the geologic requirements of the hypothesis, a comparison …

Two Lithotectonic Boundaries In Western North Carolina: Geologic Interpretation Of A Region Surrounding Sylva, Jackson County, Michael Joseph Quinn

Masters Theses

Understanding the geology of any region begins with the construction of high-quality geologic maps. As maps for a specific region are revised in greater detail, geologic understanding is improved. This study involved detailed geologic mapping (at the scale of 1 : 24,000) of a portion of the southern Appalachian Blue Ridge that was previously only mapped by reconnaissance. It is hoped that the research herein will add to the present understanding of the Blue Ridge province and of the entire Appalachian orogenic belt.

During the course of field mapping, three lithotectonic units were divided, each separated from the others by …

Paleomagnetism Of The Patagonian Plateau Basalts, Southern Chile And Argentina, Robert F. Butler, Francisco Herve, Francisco Munizaga, Myrl E. Beck Jr., Russ R. Burmester, Eduardo S. Oviedo

Geology Faculty Publications

A total of 505 paleomagnetic samples were collected from 65 sites (volcanic flows) of the Patagonian plateau basalts at four locations in southem Chile and Argentina. K/Ar analyses indicate that 38 flows from two locations form a Late Cretaceous group (64-79 Ma), while the remaining 27 flows are Eocene in age (42-56 Ma). Progressive demagnetization indicates that a characteristic remanent magnetization (ChRM) has been successfully isolated from 59 flows. Rock-magnetic prop­erties and analysis of ChRM directions within and between sites allow the secure inference that the ChRM is a thermoremanent magnetization acquired during original cooling. The Eocene flows yield 15 …

Sedimentology Of The Bedford-Berea Sequence (Early Mississippian), Williams Field, Michigan, David Alan Balthazor

Masters Theses

The Berea Sandstone has produced in excess of 1.6 million barrels of oil in the Williams field since discovery in 1980. Seven lithofacies are identified from conventional core in the Bedford-Berea sequence. These facies are interpreted as deltaic deposits comprising prodelta (Bedford Shale), delta front, destructive marine shale, abandoned distributary channel-fill, interdistributary bay-fill, transgressive marine sandstone, and marine shale (Sunbury Shale) facies. Passive channel-fill facies truncate reservoir sandstone bodies and compartmentalize the field NW-SE across the trend of the northwestplunging anticline.

The two reservoir facies in the Williams field are the delta front and transgressive marine sandstones. The sandstone framework …

An Analysis Of Dissolved Organic Compounds And Their Contribution To Iron Complexation In The Shallow Leachate Plume Of The West Kl Landfill Kalamazoo, Michigan, Eric Fahle

Masters Theses

High concentrations of dissolved iron are present in downgradient groundwater samples adjacent to the western border of the West KL Landfill. Analysis by Rudder (1988) of groundwater samples indicates oversaturation of selected iron oxides, iron sulfides and siderite in monitoring wells TW-4 and M3.

Previous research suggests that pyrogallol, gallic acid, tannic acid and similar organic compounds may retard the oxidation of ferrous iron in the shallow leachate plume of the West KL landfill (Rudder, 1988). Present research utilizing solid phase extraction, reverse phase high performance chromatography, Fourier transform IR spectrophotometry, UV/Visible spectrophotometry, and gas chromatography/mass spectroscopy indicate that pyrogallol, …
