Geology Of The Bishop 7.5-Minute Quadrangle And Geophysical Modeling To Constrain Syndepositional Deformation Of The Black Warrior Foreland Basin, Joseph Edward Lane

MSU Graduate Theses

The Black Warrior basin is a foreland basin formed by the Ouachita–Appalachian orogeny during the late Paleozoic Era. Mississippian strata record the transition from the carbonate platform within the Tuscumbia Limestone to the clastic-rich units within the overlying Pride Mountain Formation and Hartselle Sandstone. The western and southern-most fringes of the Black Warrior basin are covered by thin, post orogenic Cretaceous sediments of the East Gulf Coastal Plain. Geological mapping of the Bishop 7.5-Minute quadrangle revealed subtle deformation in Mississippian strata in the form of gentle folds (

Basal Topography And Carbon Accumulation Rate Of A Rare Northern California Coastal Fen, Sarah Leidinger

Cal Poly Humboldt theses and projects

Increasingly, the importance of peatlands as biodiversity hotpots, year-round water storage features, and significant carbon sinks are being recognized. Despite this, they are one of the most vulnerable ecosystems globally. While some peatland conservation and restoration initiatives are being developed, a greater understanding of small peatlands is needed to make management decisions. This study aims to determine the timing of peat formation, peat volume, and carbon accumulation rates of the Conspicuous Scoop Fen, a small (2.1-acre) fen near Bridgeville, California (~840 m.a.s.l.). During the summers of 2022 and 2023, I collected 39 m of peat cores at 14 sampling locations. …

Investigating The Relationship Between Inherited Geologic Framework And Saltwater Intrusion On St. Catherines Island, Georgia, Juliet Talaber, Jacque Kelly, Robert Vance

Honors College Theses

Since the late 1800s, the oldest cities on the Georgia coast have been withdrawing water from the confined Floridan Aquifer System. As the population has grown, a cone of depression has formed extending from Savannah, GA to St. Catherines Island, GA, a barrier island 50 km southeast of Savannah. On St. Catherines Island, the cone of depression has reversed the lateral and horizontal groundwater flow gradients causing saltwater intrusion into the Upper Floridan Aquifer from the Lower Floridan Aquifer through joints, faults, or solution collapse features. Previous studies from the southern and central areas of the island have found evidence …

Accretion Of Warm Chondrules In Weakly Metamorphosed Ordinary Chondrites And Their Subsequent Reprocessing, Alexander M. Ruzicka, Richard C. Hugo, Jon M. Friedrich, Michael Tyler Ream

Geology Faculty Datasets

To better understand chondrite accretion and subsequent processes, the textures, crystallography, deformation, and compositions of some chondrite constituents in ten lithologies of different cluster texture strength were studied in seven weakly metamorphosed (Type 3) and variably shocked ordinary chondrites (Ragland—LL3 S1, Tieschitz—H/L3 S1, NWA 5421—LL3 S2, NWA 5205—LL3 S2, NWA 11905—LL3-5 S3, NWA 5781—LL3 S3, NWA 11351—LL3-6 S4) using optical and electron microscopy and microtomography techniques. Results support a four-stage model for chondrite formation. This includes 1) limited annealing following collisions during chondrule crystallization and rapid cooling in space prior to accretion, as evidenced by olivine microstructures consistent with dislocation …

Integration Of 3d Structural Modelling And Well Logging Analysis In The Evaluation Of October Oil Field, Gulf Of Suez, Egypt, Lamiaa Yahia, Mostafa Toni, Farouk I. Metwalli, M. H. Mansour, Amir Ismail

Trends in advanced sciences and technology

An extensive study of the NUBIA and MAT reservoirs, incorporating numerous data sources, enhances the accuracy of production forecasts for hydrocarbon exploration and development. This study aims to integrate seismic and well data for re-assessment and to delineate the geological and petrophysical characteristics of the October oil field which is one of the most productive in the central Gulf of Suez, but it has recently witnessed a drop in output in some regions, and some wells have begun to depletion. While facies modeling enabled the spatial distribution of lithologic facies inside the constructed 3D structural model, which reflected two types …

Petrologic Relationship Between Lamprophyres, Carbonatites, And Heavy Rare-Earth Element Enriched Breccias At Hicks Dome, Jarek Trela, Jared T. Freiburg, Esteban Gazel, Laurence Nuelle, Anton H. Maria, David H. Malone, John M. Molinarolo

Faculty Publications-- Geography, Geology, and the Environment

New petrological, geochemical, and P–T modelling results from igneous samples clarify how carbonatite-lamprophyre magmatism, fluorite and rare earth element (REE) enrichment are petrogenetically related in southern Illinois. P–T modelling reveals that igneous rocks derive from a deep mantle carbonated source, that is consistent with trace element signatures for a fluorine-rich transition zone origin. Major element systematics suggests liquid-immiscibility with lamprophyric melts as the origin for Ca-carbonatites. Heavy REE (HREE) enrichments in Hicks Dome breccias likely formed through preferential partitioning and transport of HREE by brine-melts, exsolved from a deep carbonatite body. Brine-melts redistributed HREEs throughout the …

Quantifying Chemical Erosion In The Lithologically-Heterogenous Appalachian Valley And Ridge, Amelia Jayne Zanoni

Graduate Theses, Dissertations, and Problem Reports

Quantifying chemical erosion in the lithologically-heterogenous Appalachian Valley and Ridge

Amelia J. Zanoni

The interplay between physical and chemical erosion is well understood in landscapes underlain by a uniform rock type, but many regions are underlain by a mixture of rock types with varying erosion resistance and solubility. We used measurements of stream-water chemistry to estimate chemical erosion rates in the Appalachian Valley and Ridge, a region where the mechanisms of lithologic control over topography are poorly understood. Newly acquired stream water samples were collected from 51 locations across the research area during the Fall of 2023. The sampled waters …

(Non-) Recovery Of An Agricultural Stream From Straightening And Dredging, Aras Anderson Mann

Graduate Theses, Dissertations, and Problem Reports

In recent history, natural, meandering streams have been straightened and dredged to reduce flooding. While this practice can be effective in reducing flooding locally, it often results in the degradation of stream water quality and aquatic ecosystems. A straighter channel inherently increases the stream gradient, which could increase flow velocity, shear stress, and potentially downstream sediment yield. Studies have shown that straightened, channelized streams often begin to return to a meandering pattern 35-50 years post-channelization. Yet cross-sectional surveys and air photo analysis of the stream reach in this study, Deckers Creek, indicate little to no observable trend of the stream …

Estimating Inorganic Carbon Flux From Coal Mining Discharge Portals In The Bituminous Coal Field Region Of Pennsylvania, Lauren J. Rockwell

Graduate Theses, Dissertations, and Problem Reports

A fundamental driver of the adverse effects associated with coal mining is the interplay of water and oxygen within mined sites, leading to the creation of coal mine drainage (CMD). One often overlooked consequence of CMD is the release of geologically-bound carbon as carbon dioxide (CO₂). The interaction of CMD with carbonate rocks, specifically the presence of sulfuric acid driving the dissolution of these rocks, leads to the release of dissolved inorganic carbon (DIC). This study examined 25 CMD locations in an approximately 2,370 km² area within the bituminous coal field region of Pennsylvania (PA), specifically in …

The Influence Of Volcano Edifice Resonance On The Seismic Triggering Of Thermal Activity At Active Volcanoes, Morgana M. Wilke

Dissertations, Master's Theses and Master's Reports

There is an established correlation between large earthquakes and volcanic unrest, however the mechanisms between this connection are not well understood. Relatively small changes in stress within a volcanic system could be enough to initiate a response. One aspect that could serve to amplify small dynamic stress changes is volcanic edifice resonance triggered by surface waves at resonant frequency. In this paper, we investigate the relationship between thermal activity of volcanoes and various minimum thresholds of Love wave amplitudes at resonance caused by teleseismic earthquakes above a 7.0 M. Satellite-derived thermal data from 25 volcanoes are modeled in relation to …

Simulation Of Wave Propagation In Granular Particles Using A Discrete Element Model, Syed Tahmid Hussan

Electronic Theses and Dissertations

The understanding of Bender Element mechanism and utilization of Particle Flow Code (PFC) to simulate the seismic wave behavior is important to test the dynamic behavior of soil particles. Both discrete and finite element methods can be used to simulate wave behavior. However, Discrete Element Method (DEM) is mostly suitable, as the micro scaled soil particle cannot be fully considered as continuous specimen like a piece of rod or aluminum. Recently DEM has been widely used to study mechanical properties of soils at particle level considering the particles as balls. This study represents a comparative analysis of Voigt and Best …

Deglacial And Holocene Environmental Change Recorded In Lake Sediments From The Snowy Mountains, Kosciuszko National Park, Southeastern Australia, Emma J. Mickelson

WWU Graduate School Collection

The sediment record from Lake Albina, the Snowy Mountains, southeastern Australia suggests significant environmental change mostly reflecting shifts in climate from the LGM through the Holocene. Immediately following deglaciation, approximately 19.4 thousand cal ky BP, Lake Albina experienced cold and/or dry conditions with minimal vegetation in the catchment. Cooler conditions persisted with a slight increase in moisture throughout the Antarctic Cold Reversal (ACR; 14.7-13 cal ky BP) aligning closest with a strengthening of the Atlantic Meridional overturning circulation (AMOC) and a northward shift of the South Westerly Winds (SWW). Between 12.9-9.7 cal ky BP, Lake Albina recorded a climate reversal …

The Magmatic Origin Of The Columbia River Gorge, Usa, Nathaniel Klema, Leif Karlstrom, Charles Cannon, Chengxin Jiang, Jim O'Connor, Ray E. Wells, Brandon Schmandt

Geology Faculty Publications and Presentations

Along subduction zones, high-relief topography is associated with sustained volcanism parallel to the plate margin. However, the relationship between magmatism and mountain building in arcs is poorly understood. Here, we study patterns of surface deformation and correlated fluvial knickpoints in the Columbia River Gorge to link long-term magmatism to the uplift and ensuing topographic development of the Cascade Range. An upwarped paleochannel exposed in the walls of the Gorge constrains unsteady deep magma flux, the ratio of intrusive to extrusive magmatic contributions to topography, and the impact of magmatism on Columbia River incision since 3.5 million years ago. Geophysical data …

Reverse Pseudo-Gours: A New Sub-Type Of Folia Observed In The Nerja Cave (Se Spain), Cristina Liñán Baena, Concepción Jiménez De Cisneros, Yolanda Del Rosal, Paolo Forti

International Journal of Speleology

A new sub-type of folia named “reverse pseudo-gour” has been observed and described in the Nerja Cave, southern Spain. It consists of fairly vertical, thin barriers (about 5 mm high and 2 mm thick) that develop on the underside of a sub-horizontal surface (shelfstone) and grow in the opposite direction to normal gours (rimstone dams), generating sinuous shapes. Their mineral composition is essentially calcium carbonate, although globular aggregates composed of clay and phosphate minerals have also been identified. The genesis and evolution of these reverse pseudo-gours occur just at the air-water interface and are controlled by (1) the sub-horizontality of …

Studi Alimentari Italiani E Geologia: Vino E Vulcani Da Diverse Prospettive, Maria Varriale Gomez

Italian Renaissance Foodways

Nel mio progetto di integrazione avanzata, mi impegnerò in un'esplorazione interdisciplinare del vino. Analizzerò il vino utilizzando gli studi alimentari italiani e la geologia, concentrandomi in particolare sugli effetti che i vulcani hanno avuto sul vino in Italia sin dal Medioevo e dal Rinascimento. Nel corso della storia, il vino è stato una parte cruciale della cultura italiana e i vulcani del paese hanno influenzato la produzione della bevanda in modi diversi come la varietà delle uve coltivate e il suo sapore basato sulla composizione del terreno vulcanico. Le numerose regioni in Italia producono vino diverso in gran parte a …

Environmental Fate Of Sulfur In Sulphur Creek, Valles Caldera, Nm: Implications For Metal Transport And Water Quality, Daniel Lavery

Earth and Planetary Sciences ETDs

The 1.2 Ma Valles Caldera in north-central New Mexico hosts a young igneous volcanic hydrothermal system after the model proposed in Goff and Janik (2000). The Sulphur Springs area within Valles Caldera is an acid-sulfate area typical of this model, discharging acidic waters (pH 1.5-3) formed by oxidation of magmatic H₂S at the surface. We report on samples obtained from springs and streams collected between October 2021 and May 2023 in the Sulphur Creek and Alamo watersheds. Sulphur Creek receives input from Sulphur Springs and exhibits low pH (2-4) and high concentrations of Al (≤110 mg/L), Fe (≤60 …

Comparative Lineament And Geomorphic Analysis Of Chaotic Terrains And Noctis Labyrinthus, Mars, Sarah A. Walton

Electronic Theses and Dissertations

Noctis Labyrinthus (NL) is an extensional trough network connecting the Tharsis rise and Valles Marineris on Mars. Chaotic terrains are a group of polygonally-fractured surface features commonly associated with subsidence due to rapid fluid loss within the subsurface. Polygonal surface patterns are seen at both sites, where geometric topographic highs are bounded by low troughs. Lineaments, topography, and geomorphology of NL and chaotic terrains were analyzed to determine tectonics and fluid influence in the formation and evolution of both sites. NL shows preferential fracture patterns associated with regional extension. Lineaments within chaotic terrains do not show cumulative preferential trends but …

Analyzing The Shark Paleoecology Of Coastal Georgia From The Miocene And Pliocene Epochs, Joshua Lee Clark, Benjamin Angalet

Georgia Journal of Science

The field of shark paleoecology often yields indecisive conclusions based on the limited fossilization of their anatomical structures, with the exception of their teeth. The majority of the Atlantic coast has been studied regarding the presence of certain prehistoric shark species from the Miocene, Pliocene, and Pleistocene epochs. However, information pertaining to the Georgia coast and understanding its potential community structure is relatively understudied. This study was conducted in which thousands of fossil shark specimens and subsequent marine fauna were collected from dredge spoils created by the US Army Corps of Engineers (USACE): Savannah District. A total of 5,127 fossil …

Using Stromatolites To Rethink The Precambrian-Cambrian Pre-Flood/Flood Boundary, Ken P. Coulson

Proceedings of the International Conference on Creationism

The 550-meter-thick upper Cambrian (Furongian Epoch) Notch Peak Formation of western Utah has over a dozen horizons of meter- to multiple-meter-thick sequences of stromatolites that have been correlated with similar stromatolitic beds in the Drum Mountains to the north and the Wah Wah mountains to the south, providing a total geographic distribution greater than 2,600 square kilometres. Cambrian stromatolitic beds have also been described from other areas in North America that circumscribe what appears to be the ancient coast of the North American craton associated with Laurentia. A total of 24 different locations span North America starting in Newfoundland, traveling …

Orthocone Cephalopods As Paleocurrent Indicators In The Ordovician Kimmswick Formation Of Northeastern Missouri, Zachary Aaron Klein

Proceedings of the International Conference on Creationism

The intent of this project is to map and analyze orientations of large orthocone cephalopods in the Late Ordovician Kimmswick Formation to determine whether they indicate traceable current directions. The Kimmswick Formation is a medium-to-coarsely-grained crystalline limestone which is highly fossiliferous, with bedding varying from massive to cross-bedded, and ranging from 10-30 meters in thickness in the project region. Numerous orthocone cephalopods (of the genera Endoceras and Cameroceras) can be observed within the lower Kimmswick in several locations in Northeastern Missouri, especially near Imperial and Frankford. A total of 21 orientations along a six-kilometer corridor near Imperial have been …

Can Radiocarbon Dating Fit A Biblical Timescale?, Marshall Jordan

Proceedings of the International Conference on Creationism

Abstract

The trace amounts of C14 in ancient human bones imply that these people died up to 50 thousand years ago. This assumes that the concentration of C14 in the atmosphere has remained constant at today's concentration. Such ages are incompatible with the record of Genesis which places Noah’s Flood about 4500 years ago, less than one half-life for C14. The trace amounts of C14 in coals buried by the Flood show that the atmospheric concentration of C14 at the time of the Flood was about 1% of today’s concentration. So C14 can be used to date ancient carbon using …

Unresolved Issues In Hypothetical Fish-To-Amphibian Evolution, David Prentice

Proceedings of the International Conference on Creationism

This is a poster presentation bringing together multiple problems with the idea that some ancestral fish evolved into some ancestral amphibian.

The Lamarckian idea that "form follows function" has been thoroughly falsified. The only explanation for characteristics of an organism's phenotype is the content of its genotype rather than its need for new features.

The new creatures would have to undergo random mutations in their DNA to produce at least thirteen major changes. They would have to (1) leave the water and come onto land, (2) acquire two radically different types of vertebrae (rhachitomous and lepospondylous); (3) acquire segmented backbones …

Quantum Computing In Creation Geoscience, Mark Mcguire, Kathryn Mcguire

Proceedings of the International Conference on Creationism

Quantum computing has great potential in speeding up many problems. Rather than stepping “down” from a classical Newtonian realm into the more complicated quantum realm we use the same processes as the phenomena being researched.

In geoscience, quantum computing has many potential applications. For example, quantum computing can be used for simulations of radiometric dating. By simulating the decomposition of atoms, a better idea of how these decompose can be created. Simulating typical, unaccelerated decomposition would be the first step in this area of research. This can be done by creating a qbit (quantum bit) for each atom and connecting …

Gastropod Evolutionary Phylogeny, Priscilla Doran, Neal A. Doran

Proceedings of the International Conference on Creationism

This research seeks to investigate a correlation between the first appearance order date (FAD) and predicted evolutionary phylogeny of gastropods. Using a Spearman Correlation, 17 data sets of gastropods were analyzed, with a no significant correlation found between the first appearance date and predicted evolutionary date for the fossils.

Icr (2013-2023): A Decade Of Advancing The Flood-Ice Age Model, Leo (Jake) Hebert Iii

Proceedings of the International Conference on Creationism

I am proposing a poster that summarizes the last decade of paleoclimate research conducted at the Institute for Creation Research, and the ways this research has strengthened the case for the Flood-Ice Age model. The poster also discusses two research projects that I have started but as yet have not been able to finish. Here is the poster abstract:

In 1990 the Institute for Creation Research published Michael Oard’s monograph An Ice Age Caused by the Genesis Flood, which showed that warm post-Flood oceans and residual post-Flood volcanism provide the necessary conditions for an Ice Age. ICR then published additional …

Physical Evidence For A Post-Flood Lacustrine Depositional Environment For Hopi/Bidahochi Lake, Nate Loper

Proceedings of the International Conference on Creationism

Geologists both within and outside the creation community have long proposed a breached dam and lake spillover hypothesis for the formation of Grand Canyon in whole or in part. One major lake system pointed to has been dubbed Hopi Lake or Lake Bidahochi, with supporting evidence found within the Bidahochi Formation. The Bidahochi Formation in eastern Arizona overlies the Chinle Formation in many places and is described as a Miocene-Pliocene lacustrine deposit. As such, several creation geologists assign this to a depositional environment during the post-Flood Ice Age. Yet, there is a small group within the creation community who tend …

Re-Evaluating The Measurements Of Radioactive Decay, Charles A. Wolcott Jr.

Proceedings of the International Conference on Creationism

Studies investigating the validity of radiometric dating methods have raised many questions with results of methods showing ages of samples well outside the mainstream story line and a prospect of accelerated decay rates during the Flood. However, the measurements of the rates themselves have not been analyzed. This study examines a mathematical analysis of how the half-life of isotopes U-238, K-40, Rb-87, and C-14 have been measured and calls for a closer inspection of the process. The primary tool for measuring the half-life is the Geiger Counter, which only has a 20% efficiency rate, [1] while observation times of individual …

The Regression Of The Flood In Virginia, James C. Rakestraw, Jim Melnick

Proceedings of the International Conference on Creationism

The geology, tectonics, and hydraulics of the regression of the Flood formed much of the geomorphology of Virginia. Opportunities to view and study geology and geomorphology are available through visiting parks, traveling on public roads, and viewing geographic information system (GIS) resources.

Virginia is part of the North American Plate. A series of “blocks” of basement rocks within the plate underlie the geomorphological provinces of Virginia. These “blocks” form a series of steps between the Atlantic Ocean Basin and the Blue Ridge. The “Fall Line” found in Virginia is a fault between two blocks of basement rock. The basement rocks …

Geologic Analysis Of Ice Age Simulation Results, Elizabeth G. Sultan, Steven M. Gollmer

Proceedings of the International Conference on Creationism

Ice ages are believed to have occurred at least 5 times in the past, with each glacial period lasting tens of thousands of years and interglacial periods lasting up to 400,000 years. It is hypothesized, however, that the Genesis Flood would have provided the conditions necessary to trigger an ice age within a few hundred years, that could account for the glacial deposits we find worldwide. This research project compared the output data from a 360-year ModelE2.1.2 run of an ice age simulation, to the geologic record of the last glacial maximum (LGM). The simulation was inputted with conditions based …
