Precious metal, Lu-Hf, and Re-Os geochemistry of the metasomatized lithospheric mantle: implications for subcrustal precious metal mobilization and MARID petrogenesisDownload
The connection between metasomatism - the change in chemical composition of a rock via interaction with a fluid or melt - and the formation of metalliferous ore deposits in the Earth’s crust is well established. Similarly, it is now accepted that the Earth’s lithospheric mantle has experienced...
The concept of ‘winter cities’ speaks to a particular relationship between place and winter. However, winter cities are largely under examined in urban research, particularly Canadian cities. This thesis asks what type of place is a winter city and what types of placemaking occur in this context?...
50,000 years of paleoenvironmental change recorded in meteoric waters and coeval paleoecological and cryostratigraphic indicators from the Klondike goldfields, Yukon, CanadaDownload
A 50,000 year record of meteoric water isotopes (δ2H/δ18O) and paleoenvironmental conditions is presented from syngenetic ice-rich permafrost and macrofossils from eight sites in the Klondike area of central Yukon. Four sedimentary units are recognized based on cryostratigraphy, paleoecological...
This research examines the regional economic resilience of resource-based communities (RBCs) in a Canadian context. The Town of Devon in the province of Alberta, Canada is a case study for this project. The objectives of this study are 1) To develop a conceptual analytic framework to evaluate...
A Combined Membrane Filtration - Aeration Approach for the Treatment of Hydraulic Fracturing - Flowback and Produced Water from the Duvernay FormationDownload
Membrane filtration technologies have been successfully applied for the treatment of many types of wastewater. In hydraulic fracturing operations, membrane processes can be applied as a cost-effective way of removing unwanted substances from flowback and produced water (FPW) and promoting its...
A Fine Detail Physicochemical Depositional Model for Devonian Organic-Rich Mudstones: A Petrographic Study of the Hare Indian and Canol Formations, Central Mackenzie Valley, Northwest TerritoriesDownload
The Hare Indian and Canol Formations, making up part of the Horn River Group in the Northwest Territories, primarily consist of organic-rich mudstones deposited during the Middle to Late Devonian. The formations were previously considered to represent marine basin fill accumulated in an...
A Geometallurgical Approach to Assessing Critical Metal Mobility and Recoverability from Ultramafic Mine TailingsDownload
Critical metals (e.g., nickel and cobalt) are increasingly in demand for the production and storage of cleaner energy but their supplies are finite. Ultramafic mine tailings could be reprocessed as a source of critical metals. These waste materials host an array of critical transition metals and...
A Model for the Solubility of Anhydrite in H2O-NaCl fluids from 25 to 800 °C, 0.1 to 1400 MPa, and 0 to 60 wt% NaCl: Applications to Hydrothermal Ore-forming SystemsDownload
Anhydrite (CaSO4) is a common gangue mineral in hydrothermal ore-forming systems, though currently there is no robust numerical model for the solubility of anhydrite in H2O-NaCl hydrothermal fluids. Here, we present a thermodynamic model for the solubility of anhydrite in saline aqueous fluids...
A Model for the Solubility of Minerals in Saline Aqueous Fluids in the Crust and Upper MantleDownload
Quantifying and predicting the dissolution of minerals in complex (multicomponent) aqueous fluids across wide ranges of P-T space is critical for interpreting geologic processes that involve water-rock interactions in the Earth’s crust and upper mantle. Here, we define a new thermodynamic model...
