Crystal Queer: Fracturing The Binaries Of Matter, Creation, And Landscape, Sarah Knight May 2020

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, Kayla Washington May 2020

Using Foraminifera To Identify Overwash Deposits In St Vincent Island, Florida In The Wake Of Hurricane Michael, Kayla Washington

Honors Theses

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, Arianna Gaffney, Sara Mana, James Muirhead, Tobias Fischer May 2020

Testing For Magmatic Co2 Degassing Above The North Appalachian Anomaly, Arianna Gaffney, Sara Mana, James Muirhead, Tobias Fischer

Research Day

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, Cora Van Hazinga, James Muirhead, Sara Mana May 2020

Using The Extrusive Volcanic Features Of Mt. Marsabit, Kenya To Identify Regional Tectonic Stress, Cora Van Hazinga, James Muirhead, Sara Mana

Research Day

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, Rebecca Wright, Lindley Hanson, Erkan Toraman May 2020

Investigation Of The Volcanics Rocks On Marblehead Neck Through Petrographic, Geochemical, And Field Analyses, Rebecca Wright, Lindley Hanson, Erkan Toraman

Research Day

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 May 2020

Modal, Textural Analysis And Geochemical Signature Of Intrusive Igneous Rocks In A Mingling Environment At Salem Willows, Ma, Klementina Mato, Sara Mana

Research Day

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, Emily Doyle, Douglas Allen, Lindley Hanson May 2020

Application Of Xrf To The Correlation Of Colonial Bricks To A Local Clay Deposit In Southwestern New Hampshire, Emily Doyle, Douglas Allen, Lindley Hanson

Research Day

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.

Observed ...


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 May 2020

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

Research Day

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, Alisha L. Guglielmi, James L. Cullen, Annette Lott, Jerry Mcmanus May 2020

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

Research Day

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 ...
