The AAIP is an ultramafic igneous province consisting of approx. 80 known intrusives of diverse lithology and texture. ⁴⁰Ar/³⁹ Ar geochronology indicates an emplacement age of 386 +/- 1 Ma, which establishes the AAIP as the only known Devonian-age ultramafic igneous body in the Midwestern U.S. Study of the AAIP provides a unique opportunity to characterize the Devonian-age subcontinental mantle and the processes that generated the suite of ultramafic rocks present …

Paleogeogra Detrital Zircon Geochronology Of Upper Cambrian To Lower Mississippian Siliciclastic Strata Of The Ozark Dome And Vicinity, Bing Li

Masters Theses

"Siliciclastic strata exposed in the Ozark Dome provide Late Cambrian to Late Cretaceous snapshots of an evolving paleogeology and regional to far-field tectonic events. U-Pb ages of detrital zircons from the arkosic base of the Upper Cambrian Lamotte Formation reflect first cycle derivation from the adjacent ca. 1.31-1.48 Ga Granite-Rhyolite province, with subsidiary input from ca. 1.6-1.7 Ga Mazatzal basement. Feldspathic arenites near the top of the Lamotte Sandstone also contain significant quantities of detrital zircon grains of these ages, with additional peaks centered at ca. 2.7 and ca. 1.1 Ga, signaling the onset of extra-regional detrital input most likely …

Late Ordovician Tectonism In The North American Midcontinent: Constraints From U-Pb Detrital Zircon Geochronology, Daniel Nathan Meehan I

Masters Theses

"Numerous sandstone filled depressions hosted in upper Cambrian to Middle Ordovociain dolostones in south-central Missouri have historically been identified as Pennsylvanian paleokarst structures. U-Pb detrital zircon geochronology is at odds the time of formation and sedimentological evidence challenges their classification. "Filled sink" deposits yield primary zircon age populations of 2.8-2.6 Ga (~50% of all analyzed grains), 1.2-1.1 Ga (~25%), 1.8-1.6 Ga (~15%) and 1.5-1.3 Ga (~10%). These zircon populations most likely originated from the Superior Craton and Midcontinent Rift and/or Grenville orogen, respectively. The Warrensburg and Moberly channel-fill sandstones of central Missouri were identified as good candidates for Pennsylvanian aged …

Depositional Facies And Sequence Stratigraphy Of Niagaran-Lower Salina Reef Complex Reservoirs Of The Guelph Formation, Michigan Basin, Matthew J. Rine

Masters Theses

Hydrocarbon reservoirs in the Niagara-Lower Salina Reef Complex in the Michigan Basin have been extensively studied since the early 1960’s. These reservoirs host an immense hydrocarbon resource, existing as closely-spaced, highly-compartmentalized reservoirs that have produced >500 million barrels of oil and 2.9 trillion cubic feet of natural gas. Previous studies depict these “pinnacle reefs” as tall, symmetrical towers with a random distribution of facies. This study utilizes abundant core data (32 cores, 20-acre spacing), thin-section petrography, and petrophysical wire-line logs to reconstruct the geometry, facies distributions, depositional history, and sequence stratigraphy of the Columbus III Reef Complex within the Southern …

Petrological And Geochemical Evaluation Of The Sturgeon Falls Intrusive Body, Jonathan Michael Haynes

Masters Theses

The Sturgeon Falls Intrusive Body (SFIB) is a gabbroic intrusion located along the Michigan-Wisconsin border just south of the town of Norway, MI. The SFIB is bounded to the north by the Niagara Shear Zone and the Michigamme Formation (Schulz and Cannon, 2006) and to the south by an unnamed thrust fault zone and the Quinnesec Formation (Sims and Schulz, 1993). Field mapping has shown that the SFIB is composed almost entirely of metagabbro metamorphosed to greenschist facies, with isolated outcrops of clinopyroxenite, which are thought to be xenoliths.

The origin of the SFIB is controversial. Schulz and LeBerge (2003) …

Geological Controls On Stratigraphy And Sedimentation Of The Mississippian Marshall Formation, Michigan Basin, U.S.A., Joseph G. Adducci

Masters Theses

An understanding of regional orogenic, climatic, and eustatic processes is critical to the interbasinal correlation of Paleozoic strata in eastern North America. Tectonic activity associated with the culmination of Appalachian Orogenic events has been shown to have regional influence on paleostructure and sediment dispersal in the Appalachian foreland basin and adjacent intracratonic Illinois and Michigan basins. The culmination of the Acadian Orogeny at the end of the Devonian represents the beginning of a period of general tectonic quiescence extending throughout the early and middle Mississippian in eastern North America. Early Mississippian strata in the Michigan basin is distinctive and marks …

Recent Seismicity And Regional Extension Aithin Southwestern Montana, Usa, Jessica Szkody

Masters Theses

Southwestern Montana has experienced several large damaging earthquakes over the last 100 years, but many minor ones that unveil the nature of the intraplate seismicity. The region in this study is part of two distinct Late Cretaceous tectonic provinces, the Rocky Mountain Foreland Basement (RMFB) and the Cordilleran Fold and Thrust Belt (CFTB). Relationships between the two provinces and their faults show that the focal mechanisms are different. Deep focal mechanisms (between 8 and 10 km) within the RMFB can be placed on a specific fault, with many smaller events falling within the hanging wall. The hypocenters within the hanging …

Anomalous Thermal Indicators From Authigenic Minerals In Upper Paleozoic Strata Of The Michigan Basin, Kyle Cox

Masters Theses

Indications of anomalous paleo-temperatures exist in strata of the Michigan basin, USA. The thermal history of the basin was investigated through identification and analysis of authigenic components in two Upper Paleozoic strata, the Devonian Dundee Formation and Mississippian Marshall Sandstone. Formation conditions for diagenetic phases in both units were estimated through a variety of means and compared to conditions expected for a simple burial model. Authigenic clays identified in the Marshall via X-ray diffraction are expected to have formed at temperatures above what would have been produced by burial alone. Stable isotope and fluid inclusion analysis indicate the same for …

Lithologic Properties Of The Upper Ordovician Utica Formation, Michigan Basin, Usa: A Geological Characterization And Assessment Of Carbon Dioxide Confinement Potential, Frank Richard Sattler

Masters Theses

The Utica/Maquoketa Shale is considered to be the primary confining layer for Cambro-Ordovician CO₂ sequestration targets in the Midwest in the Michigan and Illinois basins, respectively. Prospective regional geologic seals in mudrock formations possess a combination of lithologic properties including nanometer scale pore space, elevated breakthrough pressures for non-wetting fluid phases and ductile mechanical deformation. Mineralogical composition is related to and typically controls these properties.

The objective of this study is to investigate the geological controls on stratigraphic and lithologic variability in the Utica/Collingwood in the Michigan basin. Twelve conventional cores and hundreds of modern well logs from the …

Thermal History Of The Michigan Basin: Results From Thermal Maturation Data And Geodynamic Modelling, Kirk A. Wagenvelt

Masters Theses

Thermal cooling, crustal convection, high temperature fluid advection, and 1.0 Km of eroded overburden are required to explain thermal maturation observations in the Michigan Basin. Observed tectonic subsidence in central Michigan follows an exponential decay indicative of thermal cooling following an anomalous heating event. Crustal convection is responsible for episodes of rapid subsidence coincident with the late Paleozoic Appalachian orogeny. Fluid advection through dilated faults reactivated by the Alleghanian orogeny brought hot fluids (as much as 255⁰ C) to the surface and impacted thermal maturation of organic matter in sediments. Models require 1.0 Km of eroded overburden to model thermal …

Previous studies were conducted in Michigan, known as the Michigan Background Soil Survey (MBSS). The current update is a refinement and improvement of the 2005 update. New data was collected from publicly available environmental files and other sources. Both the current update and the 2005 update differentiated data by soil type and glacial lobe. GIS analysis was used to observe spatial distribution of the data and to determine …

Determining Discharge From The Fallasburg Dam And The Hydrology Of The Flat River Bypass Channel, Lowell, Michigan, Seth Kuiper

Masters Theses

The Fallasburg Dam on the Flat River is required to release 110 cfs to the Bypass Channel. Residents have often reported low flows in the river, especially during the summer. The hydrology of the Bypass Channel downstream from the dam was investigated to determine whether the required flow was being released. Discharge measured at multiple transects reveal a shifts from gaining to losing conditions during the year. Gaining conditions occur during the spring and after significant rain events; losing conditions occur in the summer during dry periods. Five discharge measurements in 2013 and three in 2014 reveal flows less than …

Channel Morphology At A Meander Bend Chute Cutoff Partially Obstructed By Woody Debris, Drew Sobczak

Masters Theses

Field and flume experiments have examined the conceptual model for a meander bend in depth. Large woody debris piles are often associated with the development of a chute cutoff due to local aggradation and deflection of flow. This paper examines the bed morphology of a meander bend chute cutoff that is partially obstructed by woody debris. The bed morphology of the channel around the woody debris pile as well as the head of the cutoff are mapped. The pile is shielding the point bar immediately behind it and causing a narrow, deep channel on either side of the pile. The …

The Effects Of Industrial Biomass Gasification Ash As A Soil Amendment On The Earthworm Eisenia Fetida, Michael J. Blackowicz

Masters Theses

Soil application of solid residues from thermal conversion of biomass (i.e. combustion and pyrolysis) has become a topic of interest in recent years. However, there exists a gap in the literature with regard to soil application of gasification residues and their effects on soil health and soil macroorganisms. This study investigates the effects of three different ashes (hardwood oak/hickory, hardwood willow, corn stover), collected from industrial biomass gasification reactors (University of Minnesota Morris, Eastern Illinois University), as a soil amendment on the composting worm Eisenia fetida. Additionally, ash samples were analyzed for total polycyclic aromatic hydrocarbons (PAHs) and potentially toxic …

A New Technique For Modeling The Geomorphology Of A Slow Moving, Soft-Slope Landslide Using Terrestrial Lidar, Nathan Bradley Rohrbaugh

Masters Theses

"Soft slope movement is a big problem whether it involves an engineered slope, one that is near infrastructure, or both. Active landslides that fail slowly sometimes allow ample time to affect remedial works. In order to plan effective remedial works, there needs to be a model of the entire geometry of the slide. This thesis describes a new approach to evaluate the morphology of slope geometry using Light Detection and Ranging (LiDAR) data obtained from simple targets strategically positioned on a slide body. The data was gathered in three-month intervals over a period of one year to allow enough time …

Fault Interpretation And Reservoir Characterization Of The Farewell Formation Within Kerry Field, Taranaki Basin, New Zealand, Waleed Deefallah M Alotaby

Masters Theses

"The Kerry Field, located in the southern offshore Taranaki Basin, is a large liquid-rich gas accumulation with a thin (20 m) oil rim. The field was discovered by the New Zealand Oil & Gas in 1986 (well Kupe South-1). The gas and oil are trapped within a 9.2 km² fault-dependent three-way dip closure in the Paleocene Farewell Formation reservoir. Pressure, volume, and temperature (PVT) data indicate that the gas and oil columns in the field are in equilibrium with one another and are saturated at current reservoir conditions.

The Farewell Formation is the uppermost formation of the Kapuni Group …

A Geochemical Investigation Of Co₂ Sequestration And Site Characterization At Two Missouri Locations, Robert Allen Swain

Masters Theses

"The feasibility of sequestering CO₂ in saline aquifers of Lamotte Formation sandstone was investigated at wells located near Thomas Hill power plant, Moberly, MO and Sioux City Power Plant in Florissant, MO. Governing factors of using aquifers for CO₂ disposal include water salinity, potential for carbonic acid buffering, rate of precipitation of carbonate minerals following CO₂ introduction into the host aquifer, and the integrity of the Davis and Derby-DoeRun shale as a trap rock to prevent migration of the CO₂ phase and carbonic acid into the overlying potable Ozark Aquifer.

Both in situ and laboratory methods …

Paleogeographic And Paleoenvironmental Evolution Of Lacustrine And Fluvial Upper Triassic Zhangjiatan Shale Sequence, Ordos Basin, China, Qiuwan Yu

Masters Theses

"Detailed sequence stratigraphic and depositional systems analyses can effectively delineate factors and processes controlling deposition of fine-grained lacustrine sediments. Upper Triassic Zhangjiatan (ZJT) Shale Bed and adjacent strata in Ordos foreland basin was used as an example. A new depositional sequence model shows that the maximum regressive shoreline was more landward than that at the lowest lake-level. The study area is on the ramp margin, covering 100x90 km². Thin sections, cores and well-logs of 80 wells are used to calibrate log signatures, document lithofacies, and interpret depositional facies in a sequence stratigraphic context. The entire sequence thickens from …

Palynological Interpretations Of Deep Sea Drilling Projects Cores In The Gulf Of Mexico And Bahamian Platform, Adam Patrick Barron

Masters Theses

"One hundred drill core samples were from Deep Sea Drilling Project (DSDP) Sites 94, 98, and 540 were investigated for their palynological contents (pollen, spores, acritarchs, dinoflagellate cysts, and dispersed organic matter) to infer the paleoenvironmental and paleoceanographic history of the Gulf of Mexico and the Bahamian Platform during the middle Eocene to middle Miocene interval. At Sites 94 and 540, abundant dinoflagellate cysts (chiefly Operculodinium centrocarpum, Lingulodinium machaerophorum, Impagidinium sp., Nematosphaeropsis sp., and Spiniferites spp.) were used as paleoenvironmental indicators. Two alternating palynofacies assemblages were identified from dispersed organic matter analysis: terrestrially influenced assemblage A and marine dominated assemblage …

A Remote Sensing Based Early Warning System For Algal Blooms In Kuwait Bay And Coastal Waters, Cameron Manche

Masters Theses

The Kuwait Bay and its coastal waters are being threatened by a perpetual hazard, the proliferation of harmful algal blooms (HABS). The frequency of HAB occurrences is a growing problem that is only reported subsequent to the onset of a HAB event. Little effort has been invested in investigating the spatial and temporal distribution of these events in Kuwait Bay and even less is known about their controlling factors. All previous studies within the Kuwait Bay have focused either on measuring nutrient availability and the biodiversity of algal species.

The overall study objective is four-fold: (1) to monitor the spatial …

Michigan's Clay Bluffs: The Description And Comparison Of An Erosion-Dependent Natural Community, Nathaniel G. Fuller

Masters Theses

The clay bluffs of Michigan are a natural community found along the shores of the Great Lakes. Groundwater is found to be critical to sustaining the alkaline wetlands on the face of the bluff as well as the source of most erosion events. The clay bluffs are unusual in their vegetation, disturbance regime and geographical context. This thesis focuses primarily on describing seeping clay bluffs and exploring the comparison to other natural communities. The purpose of this is twofold, to better understand the ways in which natural communities are described as distinct from one another, and to assess the distinctness …

Effects Of Road Salt On Asylum Lake Geochemistry, Davina A. Wyman

Masters Theses

Several studies indicate that seasonal applications of road deicers can lead to saline runoff entering surface water and groundwater, which can in turn change the chemistry, density, and physical mixing patterns of urban lakes. An investigation at Asylum Lake, an urban lake located near three major roadways, was conducted to determine the degree of road salt contamination in the lake, to determine if salt loading disrupts seasonal mixing patterns, and to determine the extent of redox stratification present due to eutrophic conditions. Samples were collected monthly from the deepest point in Asylum Lake over a 19-month period and analyzed for …

Predictive Modeling In The Search For Vertebrate Fossils: Geographic Object Based Image Analysis (Geobia) In The Eocene Of Wyoming, Bryan Bommersbach

Masters Theses

The development and testing of predictive models for identifying productive fossil localities represents a promising interdisciplinary endeavor among geographic information scientists, paleoanthropologists, and vertebrate paleontologists. This thesis analyzed high resolution (2m spatial resolution) commercial satellite imagery from the Worldview-2 satellite of five areas of the Great Divide Basin using a GEographic Object-Based Image Analysis (GEOBIA) technique, which segments the image into spectrally homogeneous, multi-pixel image objects. In addition to allowing statistical analysis of the spectral characteristics of the image objects, GEOBIA techniques also let analysts incorporate expert knowledge and contextual information to improve classification accuracy. The spectral characteristics of the …

Stratigraphic Framework And Landsystem Correlation For Deposits Of The Saginaw Lobe, Michigan, Usa, Ivan R. Guzman
