At the precipice of the Great Oxygen Crash: Redox-sensitive metal geochemistry in the Paleoproterozoic Onega Basin
DownloadSpring 2021
The middle Paleoproterozoic era (~2200–1800 million years ago) was host to some of the most significant perturbations in Earth’s elemental cycles, including the largest ever excursion of carbon isotope ratios in sedimentary rocks, known as the Lomagundi-Jatuli Event. This event has been linked to...

Biogeochemistry of meromictic pit lakes and permeable reactive barriers at the Cluff Lake uranium mine
DownloadFall 2019
Mining generates not only vast amounts of waste rock and tailings but is also responsible for far-reaching contamination of soil, groundwater, and surface water, which often requires remediation. This thesis focused on the biogeochemistry of two types of remediation technologies applied at the...

Chemostratigraphy and facies analysis of the Hare Indian Formation in the Mackenzie Mountains and Central Mackenzie Valley, Northwest Territories, Canada
DownloadFall 2020
The Hare Indian Formation, a Givetian aged organic rich mudstone, is the basal formation of the Horn River Group in the Northwest Territories, Canada. It is subdivided into two members: the basal Bluefish Member and the upper Bell Creek Member. Recent interest in unconventional resource plays...

Kimberlite Indicator Minerals from the Central Mackenzie Valley, Northwest Territories, Canada: A Reconnaissance Geochemistry Survey
DownloadFall 2018
The Central Mackenzie Valley (CMV) area of Northwest Territories is underlain by Precambrian basement belonging to the North American Craton. The potential of this area to host kimberlitic diamond deposits is relatively high judging from the seismologically-defined lithospheric thickness, the age...

Fall 2021
Reconnaissance regional mapping as part of the Geological Survey of Canada’s Geomapping for Energy and Minerals (GEM-2) project documented three voluminous, massive to weakly foliated felsic plutons in Boothia Peninsula, Nunavut. Uranium-lead zircon and monazite geochronology reveals this...

Spring 2020
The Pikoo kimberlites of east-central Saskatchewan are a relatively recent discovery, comprising at least ten discreet bodies thought to erupt through the Sask Craton, a small Archean microcontinent enclosed within the Paleoproterozoic Trans-Hudson Orogen. Since the Sask Craton also plays host...

Trace Element Variability in Clay Sediments as a Function of Environmental Conditions within the Fluvial to Marine Water Transition Zone
DownloadFall 2019
Estuaries are marginal marine environments of considerable complexity, due to their spatial and temporal variations in hydrodynamic energy, water chemistry, and sediment source and composition. This complexity hinders geologists’ ability to accurately reconstruct paleoenvironments and...

Tracing Organic Contamination from Collection to Curation: Contamination Mitigation of Meteorites and Implications for Advanced Curation Methods of Astromaterials
DownloadFall 2022
Meteorites are the most primitive materials in the solar system and can provide important information about the early earth, planetary processes, and possibly yield insights to the building blocks of life. All meteoritic astromaterials are exposed to both organic compound and microbial...
