Impact Of Co2 Storage On The Geomechanical And Geophysical Properties Of Bakken Formation, Ogochukwu Ozotta

Theses and Dissertations

The world is currently experiencing a higher demand for low-carbon technologies, and carbon capture utilization and storage (CCUS) is an important CO₂ emissions reduction technology. Studies have shown the potential for CCUS in shale formations either as a caprock or as a reservoir storage unit. However, there is limited knowledge of the changes in shale reservoirs after long-term exposure to CO₂, and the resulting impacts on storage permanence. This study coupled experimental and numerical modeling methods to investigate how long-term CO₂ storage in shale formations might alter pore structure and minerals, which might cause a resultant …

Segmentation Of The Wassuk Range Normal Fault System, Nevada (Usa): Implications For Earthquake Rupture And Walker Lane Dynamics, Benjamin E. Surpless, Sarah Thorne

Earth and Environmental Geosciences Faculty Research

Normal faults are commonly segmented along strike, with segments that localize strain and influence propagation of slip during earthquakes. Although geometry of segments can be constrained by fault mapping, it is challenging to determine seismically relevant segments along a fault zone. Because slip histories, geometries, and strength of linkages between normal fault segments fundamentally control the propagation of rupture during earthquakes, and differences in segment slip rates result in differential uplift of adjacent footwalls, we use along‐ strike changes in footwall morphology to detect fault segments and the relative strength of the mechanical links between them.

We apply a new …

Florida’S Courts System Funding After Article V Revision 7, Joseph Ernest Smith, Sr.

Walden Dissertations and Doctoral Studies

The state of Florida approached the topic of funding for the courts system from a policy equilibrium position. The process used to fund Florida’s courts system was changed in 2004 to promote an equitable system of funding. However, a gap in knowledge remains regarding whether this new funding scheme improved the financial health of the courts system. This quantitative study, which involved using the punctuated equilibrium theory (PET) as its theoretical framework, examined funding associated with counties before (1998–2003) and after (2005–2018) the 2004 implementation of Revision 7 to Article V of the Florida Constitution. Revision 7 was examined as …

Investigating Depth Estimation To Archaeological Magnetic Source Bodies, Jeremy G. Menzer

Graduate Theses and Dissertations

Magnetometry is the most widely applied archaeo-geophysical technique. Current practice standards employ the technique to map only in a two-dimensional plan view fashion, but in deep geologic studies depth estimators are routinely applied to magnetic datasets. These estimators provide three-dimensional information to magnetic source-bodies. There are many different depth estimators employed in geologic study that all require various degrees of processing complexity. This study investigates two mathematically simple techniques, half-width rules and multi-height methods. Half-width rules are likely the oldest depth estimators within the field while multi-height techniques are but a minor footnote in the literature. The applicability of these …

Initial Acoustoelastic Measurements In Olivine: Investigating The Effect Of Stress On P- And S-Wave Velocities, Taryn K. Traylor, Pamela C. Burnley, M. L. Whitaker

Geoscience Faculty Research

It is well known that elasticity is a key physical property in the determination of the structure and composition of the Earth and provides critical information for the interpretation of seismic data. This study investigates the stress-induced variation in elastic wave velocities, known as the acoustoelastic effect, in San Carlos olivine. A recently developed experimental ultrasonic acoustic system, the Directly Integrated Acoustic System Combined with Pressure Experiments (DIASCoPE), was used with the D-DIA multi-anvil apparatus to transmit ultrasonic sound waves and collect the reflections. We use the DIASCoPE to obtain longitudinal (P) and shear (S) elastic wave velocities from San …

Growth Of Invasive Plant Species Communities As A Substantial Issue In Post-Mining Land Development, Paweł Olszewski

Journal of Sustainable Mining

This article concerns the issue of the appearance and growth of invasive plant species in land degraded by hard coal mining and the repercussions of this process, particularly in the context of land reclamation. These species, such as Canadian goldenrod or Japanese knotweed, which nearly always form extensive and monocultural patches of vegetation, contribute to the displacement of both native species and those introduced as part of biological restoration. In 2015, the Central Mining Institute in Katowice prepared a land development concept for a part of the area of the former KWK Paryż mine in Dąbrowa Górnicza (Upper Silesian Industrial …

Isotopic Fingerprints Of Mountain Uplift And Global Cooling In Paleoclimatic And Paleoecological Records From The Northern Tibetan Plateau, Mingqiu Hou, Guangsheng Zhuang, Minghao Wu

Faculty Publications

Post-middle Miocene changes in climate and ecology in the northern Tibetan Plateau have been attributed to tectonic uplift and global climate change. However, the relative roles of tectonism and global climate change have been a long-standing debate. To untangle the complex influences of global climate change versus the tectonism on regional climate and ecology in the northern Tibetan Plateau, we studied carbon isotopes (δ¹³Cwax) of leaf wax long-chain n-alkanes and carbon (δ¹³C) and oxygen isotopes (δ¹⁸O) of carbonates from three stratigraphic successions (ca. 16 Ma to 2 Ma) in the Hexi Corridor (foreland basin) …

Paleoseismological Findings At A New Trench Indicate The 1714 M8.1 Earthquake Ruptured The Main Frontal Thrust Over All The Bhutan Himalaya, Yuqiu Zhao, Djordje Grujic, Santanu Baruah, Dawchu Drukpa, Joanne Elkadi, György Hetényi, Georgina E. King, Zoë K. Mildon, Nityam Nepal, Caroline Welte

School of Geography, Earth and Environmental Sciences

The 1714 Bhutan earthquake was one of the largest in the Himalaya in the last millennium. We show that the surface rupture caused by this earthquake extended further to the east than previously known, it was at least 175 km long, with slip exceeding 11 m at our study site. The age of the surface rupture was constrained by a combination of radiocarbon and traditional optically stimulated luminescence dating of affected river sediments. Computations using empirical scaling relationships, fitting historical observations and paleoseismic data, yielded a plausible magnitude of Mw 8.1 ± 0.4 and placed the hypocentre of the 1714 …

Hydrothermal Alteration Of The Ocean Crust And Patterns In Mineralization With Depth As Measured By Micro‐Imaging Infrared Spectroscopy, Rebecca N. Greenberger, Michelle Harris, Bethany L. Ehlmann, Molly A. Crotteau, Peter B. Kelemen, Craig E. Manning, Damon A.H. Teagle

School of Geography, Earth and Environmental Sciences

Processes for formation, cooling, and altering Earth's ocean crust are not yet completely understood due to challenges in access and sampling. Here, we use contiguous micro-imaging infrared spectroscopy to develop complete-core maps of mineral occurrence and investigate spatial patterns in the hydrothermal alteration of 1.2 km of oceanic crust recovered from Oman Drilling Project Holes GT1A, GT2A, and GT3A drilled in the Samail Ophiolite, Oman. The imaging spectrometer shortwave infrared sensor measured reflectance of light at wavelengths 1.0–2.6 μm at 250–260 μm/pixel, resulting in >1 billion independent measurements. We map distributions of nine key primary and secondary minerals/mineral groups—clinopyroxene, amphibole, …

Exploring Questions Of Tectonic Geomorphology In The Bear River Range, Utah Using Terrain Analysis And Reconstruction, Edward M. Grasinger

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Despite a long tradition of geologic studies in the region surrounding Utah State University, there remain unexplored questions and unutilized approaches for understanding the landscape evolution of the Bear River Range. A large-scale reconstruction of the East Cache fault system can be useful in estimating the total displacement of the fault, its geologic longevity, and total energy involved. Likewise, an analysis of reach-scale features of the Logan River can explore how tectonics and bedrock type affect the patterns and history of the river. Geographic Information Systems (GIS) software is useful in reconstructing, visualizing, and measuring such geomorphological features and changes …

Simulating Cambrian Climate: The Significance Of Atmospheric Co2 Concentration And Continental Position, Grace Cutting

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

The Cambrian Period began approximately 541 million years ago, and is known for the “Cambrian Explosion”, a time when multicellular life began to rapidly diversify. There is natural historic evidence (isotopes, rock formations, and fossils) that suggests the Cambrian Period experienced a warm climate. However, there is also conflicting evidence that the Cambrian climate may have undergone freezing and thawing cycles, with ice possibly present near the equator. It is critical to understand how ecosystems were able to adapt to past climate changes, especially when analyzing the impacts of modern human activity on climate. Climate model simulations were run to …

Integration Of Geophysics And Remote Sensing Techniques In Mapping Zones Mineralised With Disseminated Gold And Sulphide Minerals In Lolgorien, Narok County, Kenya, Sammy O Ombiro, Akinade S Olatunji, Eliud M Mathu, Taiwo R Ajayi

Tanzania Journal of Science

Even though ground geophysical surveys (especially Induced polarization and resistivity) are applied in mineral exploration, their effectiveness in identification of mineralised zones is often enhanced by integrating other mineral exploration techniques such as remote sensing and geological investigations. Integrating different techniques helps in reducing uncertainty that is often associated with mineral exploration. The methods being integrated also depend on characteristics of mineralisation and those of host rock. In this study, geophysical survey methods (induced polarization and resistivity) were integrated with remote sensing and geological methods to delineate mineralised zones in Lolgorien beyond reasonable doubt. By integrating these methods, it was …

Spatial And Temporal Patterns Of River Incision And Terrace Deposition In Response To Climate And Tectonics In Southern Taiwan, Dominique M. Shore

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Geologists often look at the Earth’s surface to understand the underlying processes that cause mountain formation. As tectonic forces drive uplift of Earth’s surface, processes of erosion transport sediment to lower elevations. Climate can play a large role in landscape formation as well as increased precipitation, accelerating rates of erosion. Rivers leave markers of landscape evolution through terrace landforms, former river floodplains that are left behind when rivers incise into a valley. To better understand landscape response to uplift, this research investigated the initial linkages between uplift, hillslope erosion (mass wasting) and river incision. At some point, it is thought …

Surface Water Geochemical Characteristics Near Historical Distillery Locations In Tennessee And Kentucky, Jack Haggquist

Undergraduate Honors Theses

Kentucky and Tennessee has been the primary region in which whiskey has been produced in the United States for the last 200+ years. The locations of Kentucky and Tennessee whiskey distilleries in the pre-industrial era appear to be constrained by the geochemistry of natural waters, stratigraphy, geomorphology, and the average ambient temperatures of fermentation. Distilleries are located near first-order streams where the groundwater surfaces, indicating there was little to no manipulation of these local water sources used in the distilling process during pre-industrial America. These groundwater sources flow through heavily dominated limestone and/or Mg-rich limestone (dolostone), adjusting the geochemistry of …
