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 ... -
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. ... -
A Continuum Modelling Study of Macro-Geometry choices and Their Impact on Excavation Damage Zone Development in Brittle Rock at Depth
Canadian and International experts agree that deep underground repositories are the single best solution regarding safe, long-term nuclear waste disposal (IAEA 2009). Numerous European and Asian countries have already begun ... -
Identifying and Monitoring Rockfall Precursors Using Terrestrial Laser Scanning for Improved Rockfall Hazard Management
Rockfalls threaten communities and infrastructure in mountainous regions worldwide and have been a particularly problematic hazard along the transportation corridors in western Canada. These types of failures are traditionally ... -
An Examination of Structural Constraints on Rockfall Behaviour using LiDAR Data
Rockfall hazards along railway corridors in western Canada increase the risk of train derailment, which could lead to loss of life, infrastructure, and environmental damage. In some cases, such rockfalls exhibit pre-failure ... -
The Influence of Secondary Mineral Phase Crystallization on Antimony and Arsenic Mobility in Mine Drainage
Mine waste containing high concentrations of the potentially toxic metalloids antimony (Sb) and arsenic (As) poses a risk for the natural environment since they are toxic to various organisms. To assess this risk, it is ... -
PETROGENESIS AND METALLOGENESIS OF THE ULTRAMAFIC LAYERED NORTH LAC DES ILES INTRUSION IN THE LAC DES ILES COMPLEX, ONTARIO, CANADA
A detailed petrologic and metallogenic study was conducted on the eastern flank of the Northern Ultramafic Centre (NUC) of the North Lac des Iles Complex (North LDIC) to understand the petrogenesis of cyclically layered ... -
Origin of Visean (Mississippian) Frobisher Group Coated Grainstone Shoals in the Williston Basin: Deposition and Diagenesis
The Frobisher Beds of southeastern Saskatchewan are part of an extensive conventional oil and gas play hosted in grainy carbonate rocks, long interpreted as marine oolites. This sedimentological and diagenetic study of ... -
Ediacaran Discs: Elucidating the Form and Function of the Discoid Fossils at the Root of Metazoan Evolution
Recent suggestions that Ediacaran discs, the most common and ubiquitous fossils of the Ediacara biota, represent the holdfasts of fronds has led them to be relatively unstudied in recent years. This thesis utilizes ... -
Thermal Properties of the Cobourg Limestone
The underground storage of used nuclear fuel in Deep Geologic Repositories (DGRs) has been a subject of research in Canada for decades. One important technical aspect of repository design is the accommodation of the ...
