• Paragenesis of Gold Mineralization and Integrated Exploration Techniques of the Kiyuk Lake Project, Kivalliq Region, Nunavut, Canada 

  Jones, Stacie

  Exploration for gold in Nunavut has primarily focused in Archean greenstone belts in the north and coastal regions of the territory, resulting in large areas of unexplored terrain. The Kiyuk Lake property is located in the ...

• Spatial variations of pressure-temperature-timing-deformation conditions of ductile thrusts: Examples from the Himalayan and Variscan orogens 

  Braden, Zoe

  Orogen-scale thrust-sense shear zones evolve dynamically through time and space as they accommodate crustal shortening during continental collision. When these shear zones activate in different parts of an orogen is central ...

• On the Detectability of Density Distributions of Asteroids and SAGD Reservoirs Using Gravimetry and MUON Tomography 

  Dabboor, Oday

  In this thesis, the procedures of modelling density distributions for different targets are investigated. In the process of evaluating density distributions of asteroids, gravity forward modelling shows that homogeneous ...

• Soil from the Yellowknife, NT Region: Spatial Distribution of Arsenic, Characterization of Solid Phase Arsenic Hosts, and Distinguishing Giant and Con Mine Contamination 

  Oliver, Jonathan

  Historical gold mining in the Yellowknife, Northwest Territories region has led to a legacy of arsenic contamination in the region. Roasting of arsenopyrite hosting gold ore released arsenic trioxide (As2O3) via airborne ...

• Game-Engine Based Rockfall Modelling: Testing and Application of a New Rockfall Simulation Tool 

  Sala, Zac

  Rockfall presents an ongoing challenge to the safe operation of transportation infrastructure across Canada, creating hazardous conditions which can result in damage to roads and railways, as well as loss of life. Conventional ...

• Identifying rockfall hazards in the Fraser Canyon, British Columbia: a semi-automated approach to the classification and assessment of topographic information from airborne LiDAR and orthoimagery 

  Carter, Richard

  Rockfall hazards on railway corridors create risk of derailment which can result in damage to property or the environment and cause injury or loss of life. There is interest in understanding the location and severity of ...

• Modelling of Hard Rockmasses with Non-Persistent Joints to Assess the Stress Induced Damage of Deep Excavations 

  Vazaios, Ioannis

  Brittle fracturing within low confinement environments is the dominant failure mechanism of hard rockmasses under high magnitude in situ stresses around underground excavations. With an emphasis on the behaviour of slightly ...

• EPB Excavation and Conditioning of Cohesive Mixed Soils: Clogging and Flow Evaluation 

  Garroux Gonçalves de Oliveira, Daniela

  When shield tunnels are being excavated along varying geological conditions, it is essential to understand the behaviour of the material being excavated, as it influences excavation speed and ground stability, in addition ...

• Laboratory Investigation of Shear Behaviour in Rock Joints Under Varying Boundary Conditions 

  Packulak, Timothy

  Discontinuities (joints, fractures, faults, bedding planes etc.) in rockmasses are an important mechanical component of a rockmass. In low to moderate in situ stress conditions where gravity-driven failure dominates, these ...

• Structural style and timing of deformation on the Bathurst fault in the eastern Slave craton, western Nunavut, Canada 

  Ma, Svieda

  Crustal-scale basement faults persist as long-lived structures that localize deformation and can enhance permeability in the Earth’s crust. The NNW-striking left-lateral Bathurst fault in the eastern Slave craton displaces ...

• Tectonometamorphic Evolution of the Karnali and Jajarkot External Crystalline Klippen, Western Nepal Himalaya 

  Soucy La Roche, Renaud

  Field mapping and microstructural characterization of metamorphic rocks exposed in the Karnali and Jajarkot klippen in the western Nepal foreland highlight the presence of a top-to-the-southwest shear zone at the base and ...

• Method Development for the Systematic Separation of the <63 µm Heavy Mineral Fraction from Bulk Till Samples 

  Pickett, Jessica

  Undiscovered ore bodies have become increasingly more difficult to target, requiring new exploration techniques to pinpoint the undercover location. Sedimentary overburden in regions of intense glaciation have made exploration ...

• The Viability of Lithogeochemistry and Surficial and Surficial Geochemistry in Detecting CU-AU Porphyry Mineralization Under Cover in the Lachland Fold Belt, Australia 

  McGill, Cole

  The Racecourse prospect is a possibly economic alkalic Cu-Au porphyry system, situated within the Macquarie Arc, NSW, Australia. Similar in age to both the Ordovician Cadia and Northparks districts of NSW, a volcano-sedimentary ...

• Laboratory Ultrasonic Pulse Velocity Logging for Determination of Elastic Properties from Rock Core
