Behaviour of Ore-Forming Elements in the Sub-Continental Lithospheric Mantle Below the Slave Craton
DownloadFall 2020
The transport and depositional controls of ore-forming elements such as Ag, Au, Bi, Cu, Mo, Pb, Pt, and Zn has been extensively studied in crustal environments, but the behaviour of these elements within Earth’s mantle require further study. This thesis presents new petrographic and geochemical...

Beyond mountain pine beetle: soil carbon storage a decade after tree mortality and the possible influence of soil fungi
DownloadSpring 2024
Mountain pine beetle (MPB; Dendroctonus ponderosae) disturbances, amplified by climate change, have led to extensive tree mortality and ecosystem succession in boreal forests across western Canada. Often following attack, former ectomycorrhizal (EM) pine stands in Alberta are replaced by...

Spring 2010
Land use and land use change strongly influence the carbon (C) dynamics within ecosystems. This study quantified four aspects of land use and land use change effects: 1) ecosystem C stocks and distribution; 2) soil respiration; 3) soil C mineralization; and 4) net ecosystem productivity. Land use...

Characterization of the Geothermal Resource at Clarke Lake Field Northeast British Columbia
DownloadFall 2020
Clarke Lake is a depleted gas fi eld developed in carbonate platform deposits of the Slave Point Formation (Middle Devonian) in northeastern British Columbia, Canada. It displays anomalously high reservoir temperature and strong water drive, making it a candidate for repurposing as a source of...

Conductive Atomic Force Microscopy Study of Electron Transport Through Diazonium Derived Films and Mixed – Mode Bonded Layers on Gold and Carbon Surfaces
DownloadSpring 2012
For Molecular Electronics to become a viable replacement or complitment to current elec- tronic devices a fundamental understanding of device operation and functionality is needed. This work explores electron transport through diazonium derived molecular junctions via conductive atomic force...

Development and application of the Re-Os isotope system to sediment-hosted Zn-Pb ores and sedimentary pore waters
DownloadFall 2018
The rhenium-osmium (Re-Os) isotopic system is used to determine the age of, and trace the origins of, minerals and fluids found within the Earth's crust. This thesis focuses on application of Re-Os geochronology and isotope systematics to sulphide minerals from carbonate-hosted Zn-Pb ore...

Development of High Efficiency and New Selectivity Liquid Chromatographic Phases for the Separation of Ionic and Hydrophilic Analytes
DownloadFall 2013
Separation of low molecular weight ions and hydrophilic analytes is achieved by high performance ion chromatography (IC) and hydrophilic interaction liquid chromatography (HILIC). The goal of this thesis was three-fold: to increase the efficiency of IC separations by employing small particles; to...

Diagenetic Controls on Hydrothermal Fluid Flow in the Osiris, Isis, and Isis East Carlin-Type Gold Showings, Nadaleen Trend, Yukon
DownloadFall 2015
Following ATAC Resources Ltd.’s 2010 discovery of the gold prospects in the Nadaleen Trend (Central Yukon), company geologists and consultants determined that Precambrian carbonate rocks within the trend contain large endowments of gold located in the hinges of anticlines and fault zones. ...

Dissolved Organic Carbon Mobilization and Degradation Patterns in Retrogressive Thaw Slumps of the Peel Plateau, Northwest Territories, Canada
DownloadFall 2016
Anthropogenic climate change has affected the Canadian Arctic cryosphere, accelerating the development of retrogressive thaw slumps (RTS) across the Peel Plateau, NWT, Canada. RTS result from the thawing of ice-rich permafrost and develop due to ablation of ground ice exposed in the slump...

Spring 2018
The northern Appalachian Orogen was built during multiple orogenic episodes resulting from Cambrian through Devonian accretion of microcontinents and/or crustal ribbons to the eastern margin of Laurentia. Orogenic loading formed a foreland basin on the Laurentian craton. Orogen-derived sediments...
