Crystal Queer: Fracturing The Binaries Of Matter, Creation, And Landscape, 2020 Washington University in St. Louis
Crystal Queer: Fracturing The Binaries Of Matter, Creation, And Landscape, Sarah Knight
Graduate School of Art Theses
In this thesis, I compile a series of fragments consisting an analysis of my artwork in the gendered contexts of landscape, self-identity, mythology, and philosophy. I develop my concept of a “queer mark” in my art that serves as a form of queering, a disruption of visual and conceptual cohesion. I form a picture of how our contemporary selves are influenced by our gendered understanding of the landscape through the analysis of philosophical, artistic, and mythological concepts of creation. I see my sculptures as an atlas to an alternative means of understanding identity, a queering of these historical and exclusionary ...
Using Foraminifera To Identify Overwash Deposits In St Vincent Island, Florida In The Wake Of Hurricane Michael, 2020 Coastal Carolina University
Using Foraminifera To Identify Overwash Deposits In St Vincent Island, Florida In The Wake Of Hurricane Michael, Kayla Washington
Major hurricanes have geomorphic and stratigraphic impacts in coast environments that can be used to identify and characterize the storms. One of the approaches to identify storm impact is by studying assemblage of foraminifera, small organisms that live primarily in marine environments with some species living in marshes, in coastal marshes or ponds, with the assumption that storm-induced overwash flooding brings marine species ashore. Hurricane Michael made landfall ~40 km northwest of St Vincent Island (SVI), Florida, on October 10, 2018, as a Category 5 storm. The storm surge of Michael inundated a large part of SVI, which offers a ...
Testing For Magmatic Co2 Degassing Above The North Appalachian Anomaly, 2020 Salem State University
Testing For Magmatic Co2 Degassing Above The North Appalachian Anomaly, Arianna Gaffney, Sara Mana, James Muirhead, Tobias Fischer
The Northern Appalachian Anomaly is a thermal anomaly inferred from shear wave velocities beneath New England and interpreted as a mantle plume. Possible evidence of magmatism is investigated here by analyzing soil CO2 flux emissions in areas surrounding regional springs in New York, Massachusetts, New Hampshire and Vermont. To test the presence of magmatism at depth, we measured the flux of diffusely degassing soil CO2 using an EGM-5 portable CO2 gas analyzer. We hypothesize that magmatic CO2, if present, will produce a CO2 degassing signature distinguishable from a shallow biogenic CO2 source. Samples were taken in areas with springs because ...
Using The Extrusive Volcanic Features Of Mt. Marsabit, Kenya To Identify Regional Tectonic Stress, 2020 Salem State University
Using The Extrusive Volcanic Features Of Mt. Marsabit, Kenya To Identify Regional Tectonic Stress, Cora Van Hazinga, James Muirhead, Sara Mana
Extrusive volcanic features like vents, craters, and cones can produce alignments and other linear structures that indicate the orientations of feeder dikes and regional tectonic stresses. These dikes form parallel to the maximum compressional stress (σ1) and perpendicular to minimum compressive stress (σ3), and/or exploit preexisting planes of weakness. Volcanic constructs fed by these magmatic intrusions are therefore indicators of tectonic stress directions and subsurface structural fabrics, which can be deduced through detailed mapping and assessment of the spacing, shapes, and linear arrays of these volcanic features.
Mt Marsabit (2.32°N, 37.97°E) is a massive 6 ...
Investigation Of The Volcanics Rocks On Marblehead Neck Through Petrographic, Geochemical, And Field Analyses, 2020 Salem State University
Investigation Of The Volcanics Rocks On Marblehead Neck Through Petrographic, Geochemical, And Field Analyses, Rebecca Wright, Lindley Hanson, Erkan Toraman
Marblehead Neck is a rocky island within the Dedham-Milford zone in northeastern Massachusetts and is separated by the younger Late Silurian Salem Gabbro-Diorite on the adjacent mainland of Marblehead by a fault of unknown motion. Although shown on the 1983 bedrock map of MA, to be underlain by the Late Proterozoic Dedham Granodiorite and Lynn Volcanics, attempts to date and definitively correlate these rocks have been unsuccessful. This study focuses on confirming the identity of the volcanics and correlating to local lithologies(Middlesex Fells Complex, Lynn-Mattapan Volcanic Complex, Newbury Volcanics, and extrusives of the Cape Ann Granite) through field mapping ...
Modal, Textural Analysis And Geochemical Signature Of Intrusive Igneous Rocks In A Mingling Environment At Salem Willows, Ma, Klementina Mato, Sara Mana
This study focuses on the variation of mode, texture and geochemical signature of heterogeneous igneous intrusive rocks found at the contact between felsic and mafic melts intruded within the West Avalon terrane at Salem Willows, Massachusetts. Here, the mafic unit is generally interpreted as the Salem Gabbro-Diorite (~424 Ma) while the felsic unit is commonly assigned to the Beverly Syenite (~425 Ma).
A felsic sample and two mafic samples were selected to represent extreme examples of the various composition and texture observed along the outcrop. The samples were analyzed with a petrographic microscope and for whole rock geochemistry. Grain size ...
Application Of Xrf To The Correlation Of Colonial Bricks To A Local Clay Deposit In Southwestern New Hampshire, 2020 Salem State University
Application Of Xrf To The Correlation Of Colonial Bricks To A Local Clay Deposit In Southwestern New Hampshire, Emily Doyle, Douglas Allen, Lindley Hanson
Handmade, colonial bricks are eroding from a stream bank along the Cold River, South Acworth, NH. Bricks were regularly made close to local sources. There are two potential sources: glacial lake clays from the Cold River Valley and glacial lake clays further downstream in the Connecticut River Valley. The predicted source is a varved clay deposit 100m upstream. A sample of this clay deposit was collected along with two bricks for trace element analysis using XRF spectroscopy. Determination of the mineralogy was attempted using a petrographic microscope. However, minerals in the clay-fired matrix were too fine-grained to be identified.
Detailed Records Of Ird Input From Central North Atlantic Sediment Core Vm28-89 During The Last Glacial Cycle (Marine Isotope Stages 4-2), Adam Surette
High resolution records from North Atlantic deep-sea sediment have been instrumental in documenting millennial-scale climate variations during the last glacial cycle (Marine Isotope Stages (MIS) 4 to 1) including variations of Ice-Rafted Detritus (IRD) concentrations related to massive iceberg discharges from glacial continental ice sheets. We have sampled core VM28-89, located within the Ruddiman IRD Belt in the central North Atlantic at 1 cm intervals and produced detailed records of %IRD ((number of lithic grains >150μm / (number of lithic grains >150μm + number of Planktic foraminifers >150μm)) x 100); lithic grains, >150μm per gram of sediment (lithics/gram); planktic foraminifers, >150μm ...
Records Of The Late Glacial Influx Of Ice-Rafted Detritus On The Orphan Knoll, Northwest Atlantic Ocean, 2020 Salem State University
Records Of The Late Glacial Influx Of Ice-Rafted Detritus On The Orphan Knoll, Northwest Atlantic Ocean, Alisha L. Guglielmi, James L. Cullen, Annette Lott, Jerry Mcmanus
The top 110 centimeters of IRD records for GVY002 reveal 5 distinct peaks in IRD input, each between 4000-6500 lithics/gram. Three of these peaks coincide with three peaks in the Ca/Sr ratios in the upper meter indicative of dolomite rich IRD from the Canadian margin.
The IRD record and Ca/Sr ratio record generated in this study, when compared to the previously generated similar records in GVY001, reveals a similar pattern but over a much longer downcore sediment interval (over the upper 4.5 meters in GVY001 versus the upper 1.8 meters in GVY002). This is due ...
Nanotextural And Nanochemical Constraints On The Role Of Heat In The Development Of Crystalline-Hosted, Silica-Rich Fault Mirrors In The Wasatch Fault Damage Zone, Utah, Usa, 2020 Utah State University
Nanotextural And Nanochemical Constraints On The Role Of Heat In The Development Of Crystalline-Hosted, Silica-Rich Fault Mirrors In The Wasatch Fault Damage Zone, Utah, Usa, Leah M. Houser
All Graduate Theses and Dissertations
Earthquakes occur on faults, or rock that has experienced displacement at depth. Experimental work on a range of rock types reveals that >90% of earthquake energy on fault surfaces is given off as heat. Heat weakens rock and promotes earthquake rupture propagation. Thin (<0.5mm), high-gloss, “polished”, light-reflective exposed fault surfaces are called fault mirrors (FMs). Fault mirrors may record rapid thermal, textural, and chemical changes that occur during an earthquake event.
The Wasatch Mountains are a N-S trending mountain range in Northern Utah that are the backdrop for Salt Lake City, Provo, Ogden, and Brigham City. This mountain range is currently built by the active Wasatch fault, and includes the exposed Wasatch fault damage zone. Many segments of the Wasatch fault are overdue for a potentially catastrophic earthquake ...0.5mm),>
Chemical Weathering Of Deposits From The 1980 Mount St. Helens Eruption And Its Effect On Stream Water Chemistry, 2020 Eastern Washington University
Chemical Weathering Of Deposits From The 1980 Mount St. Helens Eruption And Its Effect On Stream Water Chemistry, Darlene Gilroy, Dr. Carmen Nezat
2020 Symposium Posters
Chemical weathering is an ongoing natural phenomenon that aids in the breakdown of solid rocks and contributes to the chemistry of natural waters and soils. Therefore, studying chemical weathering in a given area may provide a better understanding of the natural influencers on nearby water chemistry. The eruption of Mount St. Helens (MSH) in 1980 provides a unique opportunity to study the chemical weathering of young rocks which typically weather more rapidly than older rocks.
The aim of the study was to determine the relative resistance of the volcanic rocks from the 1980 MSH eruption to chemical weathering by using ...
Impact Of Compactive Effort On Soil Strength Of Glacial Lake Columbia Soils, 2020 Eastern Washington University
Impact Of Compactive Effort On Soil Strength Of Glacial Lake Columbia Soils, Alexander M. Navarra, Dwight Hendrickson, Jaremy Shaw
2020 Symposium Posters
Glacial Lake Columbia (GLC) existed from 15,550 (+/- 450) to 13,050 (+/- 650) years ago (Atwater, 1986) as a result of the Okanagan Lobe of the Cordilleran Ice Sheet damming the Columbia River near present-day Grand Coulee Dam. The lake deposited a fine-grained basal layer that had interbeds of coarse Missoula Flood deposits and later lake deposits above. Because these GLC deposits are present around most of the Spokane area, they are important to civil engineering and development. We sampled the basal layer of GLC soils from the Peone Prairie, WA. We performed prerequisite testing before the main experiment, with ...
Experiments To Synthesize Soft-Sedimentary Deformation And Clastic Dikes, 2020 Eastern Washington University
Experiments To Synthesize Soft-Sedimentary Deformation And Clastic Dikes, Chelsi K. Howard
2020 Symposium Posters
Clastic dikes are intrusions of sediments into layers of other sedimentary strata that are found in various places across eastern Washington. Three notable sites include Burlingame Canyon in Touchet, WA, Tucannon Valley near Starbuck, WA and Campion Park in Spokane, WA. Clastic dikes are thought to be formed by either overburden stress or from seismic activity. In eastern WA, the dikes were formed by large overburden pressure and seismic-like forces caused by cataclysmic floods that washed over eastern WA (known as the Missoula floods). We recreated this environment by layering saturated sand below and on top of kaolinite clay, and ...
Unmasking A Terrane Triple Point In Central Virginia, 2020 William & Mary
Unmasking A Terrane Triple Point In Central Virginia, Ryan Walter
Undergraduate Honors Theses
The central and southern Appalachian Piedmont contains terranes with both Laurentian and Gondwanan affinities that were amalgamated during a series of Paleozoic orogenies. In the southwestern Virginia Piedmont, the Smith River Allochthon (SRA) is interpreted as a peri-Gondwanan or distal Laurentian regional scale thrust sheet of metaclastic and meta-igneous rocks. The SRA was first identified in southern Virginia, and regional-scale maps extend the SRA northeast into the central Virginia Piedmont along the boundary between the Blue Ridge (BR) and western Piedmont (WP). In southern Virginia, the Bowens Creek fault separates the BR from the WP, and regional maps project this ...
Exploration Of Abandoned Mine Shafts By Means Of Seismic Refraction, Electrical Resistivity Tomography, And Ground Penetrating Radar: Case Study At Centralia, Pa, Jackson Long
Senior Scholars Day
Near surface geophysical methods have been heavily used in mapping geological structures, and in the identification of mine shafts and underground void spaces. In this study, a site in Centralia, PA, was selected as an experimental site to study the relative effectiveness of Seismic Refraction (SR), Electrical Resistivity Tomography (ERT), and Ground Penetrating Radar (GPR) to detect abandoned mine shafts. Centralia is well known for its extensive mine fire, as well as many abandoned mines. All surveys were performed along the same transect at Centralia. SR and ERT were appeared to be the effective methods of mine shaft detection. Dipole-Dipole ...
A Fossil Guide For The Community: The Shale Pit In Beaver Springs Pa, 2020 Susquehanna University
A Fossil Guide For The Community: The Shale Pit In Beaver Springs Pa, Jake Mount
Senior Scholars Day
This study produced a fossil guide for the public from a shale pit owned by Spring Township located at Beaver Springs, PA. This shale exposure, located along Shale Pit Road, represents the Sherman Ridge Member of the Mahantango Formation (Middle Devonian- Givetian). At this location, the exposure is composed of 9-10 m of dark, iron-stained greenish-gray shale, however there is a thin, light bluish-gray, iron-stained shaley-sandstone ledge, ~1 m thick, that occurs within the succession. The shale contains rare to sparse bivalves, straight cephalopods, trilobites, several types of gastropods, crinoid stems and a partial calyx, and carbonized wood. The sandstone ...
136— Predation On Microbivalves By Juvenile Naticid Gastropods On San Salvador Island, The Bahamas, Eliza Merges
Predator-prey interactions, where snails eat clams, evolutionarily has been a key interaction within marine molluscan communities. There is evidence of molluscan extinctions in the fossil record that are marked by changes in predation ratios. In this study, we will investigate predation of microbivalves by juvenile naticid gastropods in a shallow marine setting on San Salvador Island in the Bahamas. We propose to test predation density within different environments (facies) of a lagoonal setting. Significantly different ratios between these facies in one time period can indicate that predator-prey interactions can change over time from one environment to another. It is more ...
279— Magnetic Susceptibility Of Kettle Point Formation, Ontario, Canada, 2020 SUNY Geneseo
279— Magnetic Susceptibility Of Kettle Point Formation, Ontario, Canada, Abigale O'Connor
The Kettle Point Formation is an Upper Devonian black shale that preserves the Frasnian-Famennian boundary, which marks the most extreme of the three extinction events that comprise the Late Devonian mass extinction. The purpose of this study is to determine a high resolution location of the boundary within the Gore of Chatham core from Ontario, Canada. This determination will improve the understanding of the environmental conditions leading up to the Kellwasser event of the Late Devonian mass extinction. The specific location of the boundary will also improve the ability to correlate this rock unit to others that were deposited during ...
411— Analysis Of Hillslope Stability, Harriman, Tennessee, 2020 SUNY Geneseo
411— Analysis Of Hillslope Stability, Harriman, Tennessee, Walter Hennings, Anthony Wagman
We seek to conduct a hillslope safety analysis of a hill located in Roane County, Tennessee, composed of the Gilpin-Petros soils. This unit is composed primarily of residuum from sandstone, siltstone, and shale. The stability of the hill was assessed using a one-dimensional infinite slope-stability model. This model was used to calculate the factor of safety under both dry and wet conditions based on a set of assumptions derived from soil lithology and hydrologic parameters. Simulations in ArcGIS show that under dry conditions, the slope is unconditionally stable at all locations. Under conditions of sufficiently heavy rainfall (>9 inches of ...
253— The Impact Of Physical And Chemical Weathering On Iron Slag From Standish, Ny, Maria Leonard
From 1883 to 1907, magnetite ore was smelted Standish, NY. During this time, a large amount of slag, a byproduct of smelting, was created. The slag is now in a pile that covers ~13 acres in the northeastern region of the Adirondacks. The impact of weathering is evident through a comparison of samples collected ~15 years ago to partner samples still out in the field which are more fractured and have calcitic weathering rinds. For more quantitative data, we carried out a field experiment and a leaching test. In the field experiment we exposed different slag samples (glassy, chalky, and ...
