Spatial variations of pressure-temperature-timing-deformation conditions of ductile thrusts: Examples from the Himalayan and Variscan orogens
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
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
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
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
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
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
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 ... -
Structural style and timing of deformation on the Bathurst fault in the eastern Slave craton, western Nunavut, Canada
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
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
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
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
During the development of deep underground excavations spalling and rockbursting have been recognized as significant mechanisms of violent brittle failure. In order to predict whether violent brittle failure will occur, ... -
Geometallurgical and Geological Evaluation of the High-Grade Polymetallic Unconformity-Related Cigar Lake Uranium Deposit
The high-grade, polymetallic, unconformity-related, Cigar Lake uranium deposit, located in northern Saskatchewan, Canada, is the focus of a detailed mineralogical, geochemical and geospatial study aimed at geometallurgical ... -
Laboratory Strength Testing of Argillaceous Limestone Under Varying Saturation, Scale, Loading Rate, and Confinement Conditions
The Deep Geological Repository (DGR) concept is the proposed solution for the long-term storage of nuclear waste in Canada. While site selection processes are currently underway for high-level waste storage, a low and ... -
An Analysis of Failure Mechanism constraints on Pre-Failure Rock Block Deformation using TLS and Roto-Translation Methods
(2017-08-31)Rockfall hazards increase the risk of train derailment along railway corridors in western Canada. In this study, repeated Terrestrial Laser Scanning (TLS) datasets were collected every 2-3 months at three different sites ... -
Mineralogical, Geochemical and Isotopic Compositions of Fracture Coatings in Athabasca Group Sandstones as Records of Elemental Dispersion
The McArthur River unconformity-related uranium deposit (~500 m depth) and the deep Stewardson Lake uranium project (~1100 m depth) are located in the eastern and south-central sections of the Athabasca Basin. By examining ... -
Stress Estimation From Borehole Scans For Prediction Of Excavation Overbreak In Brittle Rock
In the field of geomechanics, one of the most important considerations during design is the state of stress that exists at the location of a project. Despite this, stress is often the most poorly understood site characteristic, ... -
Characterization of arsenic-hosting solid phases in Giant mine tailings and tailings dust
Dust from the tailings at Giant mine, an abandoned mine in northern Canada, has been a concern among local residents, particularly those from Ndilo, a community of Yellowknives Dene First Nations located approximately 2.5km ... -
Surface Water Classification and Monitoring using Polarimetric Synthetic Aperture Radar
Surface water classification using synthetic aperture radar (SAR) is an established practice for monitoring flood hazards due to the high temporal and spatial resolution it provides. Surface water change is a dynamic process ... -
Analysis of Clay Minerals in the Mudflats of Sulfate-Rich Saline Lakes
Clay minerals are important targets for interpreting past environments due to their ubiquity on the surface of terrestrial planets, sensitivity to the prevailing geochemical conditions, and ability to preserve biosignatures. ...
