Factors Controlling Tungsten Mobility in W-Cu Skarn Tailings from the Cantung Mine, Northwest Territories, Canada
Few studies have addressed the mobility of tungsten in mine waste, which could act as a point source for metal leaching. This study addresses the behaviour of tungsten in tailings at the Cantung Mine in the Northwest ... -
Assessment of Rockfall Deformation and Related Geometric Characteristics via Terrestrial Laser Scanning
Due to the required numerous and extensive rock cuts through steep topography and adjacent steep natural slopes, rockfalls are a common risk to which the Canadian National Railway (CN) and Canadian Pacific Railway (CP) ... -
Review of Close-Range Three-Dimensional Laser Scanning of Geological Hand Samples
(Elsevier, 2020)The morphological study of geological hand samples has a wide variety of applications in the geosciences, which is conventionally accomplished by measuring the distance between features of interest on the sample’s surface. ... -
Characterization of Tailings Dust from Two Abandoned Mine Sites: Effects on Nearby Surface Waters and Evaluation of Dust Sampling Methods
Canada’s climate is warming and as a result the hydrological cycle is expected to become more intense, with rainfall concentrated in extreme events with longer dry spells. Consequently, dry tailings may be more likely to ... -
Glimpses of Oceanic Lithosphere of the Challenger Deep Forearc Segment in the Southernmost Marianas: The 143°E transect, 5800–4200 m
(Wiley, 2020-06-16)We studied nine samples of igneous rocks from the inner wall of the Mariana Trench above the Challenger Deep from 4150 to 6100 m depth recovered by manned submersible and ROV. Samples from two regions that bracket the Moho ... -
Characterization of Rock Salt Response to Blasting using Terrestrial Laser Scanning Technology
This doctoral research project addresses some of the fundamental aspects for blast design methods in rock salt mines. An experimental field work protocol was devised based on the use of single hole blast (SHB) tests to ... -
An Epeiric Glass Ramp: Permian Low-Latitude Neritic Siliceous Sponge Colonization and its Novel Preservation (Phosphoria Rock Complex)
(Elsevier, 2019-11-29)Glass ramps are shallow-marine depositional settings in which siliceous sponge meadows dominate coastal environments. They are increasingly recognized throughout the Phanerozoic and represent a biosiliceous counterpart to ... -
Autonomous Bathymetric and Magnetic Surveying for Canadian Lakes
Magnetic surveys are an important step in the process of mineral and archaeological exploration. Current magnetic surveying methods include mounting magnetometers to various survey platforms including inhabited airplanes, ... -
Copper Isotopic Analysis in Geological and Biological Reference Materials by MC‐ICP‐MS
(Wiley, 2020-01-24)The characterisation of relative copper isotope amount ratios (δ65Cu) helps constrain a variety of geochemical processes occurring in the geosphere, biosphere and hydrosphere. The accurate and precise determination of δ65Cu ... -
Phosphorites, Glass Ramps and Carbonate Factories: The Evolution of an Epicontinental Sea and a Late Palaeozoic Upwelling System (Phosphoria Rock Complex)
(Wiley, 2020-03-11)The Permian Phosphoria Rock Complex of the western USA contains an enigmatic assemblage of bioelemental rocks (i.e. phosphorites and cherts) that accumulated in a depositional system with no modern analogue. This study ... -
High Spatial Resolution Measurement of Tendon Reinforcement in Underground Construction Works
Distributed optical fiber strain sensing is investigated as a technology to enhance the assessment of tendon reinforcement elements that are commonly used in mines and tunnelling projects. Central to this research effort ... -
Reliability of Stress Induced Damage Predictions in Hard Rocks With Continuum and Discontinuum Numerical Modelling Approaches
The use of underground repositories known as deep geological repositories (DGR) is globally accepted to be the best solution for long term storage of nuclear waste. In combination with different types of engineered barriers, ... -
High‐resolution unmanned aerial vehicle aeromagnetic surveys for mineral exploration targets
(Wiley, 2020-01)Recent advancements in geophysical exploration have been realized through reliably integrating unmanned aerial vehicle platforms with lightweight, high‐resolution magnetometer payloads. Unmanned aerial vehicle aeromagnetic ... -
Geomechanics and Mineralogical Characterization of Intact Heterogeneous Rocks from the Legacy Skarn Deposit
Predicting the geomechanical behaviour of rockmasses is key to the economic success and safety of rock engineering projects such as surface and underground excavations. For these projects, unconfined compressive stress ... -
Trace and Isotopic Geochemistry of Groundwaters in Mineral Exploration
Total cover (100 % coverage) presents a challenge for mineral explorers, with the effectiveness of traditional geochemical techniques greatly reduced. Hydromorphic mobilization of solutes can produce geochemical footprints ... -
Arsenic mobility in a changing northern climate: Implications for geochemical baselines and long-term stability of contaminants in lake systems
Climate change is influencing the biogeochemical dynamics of lake systems in northern Canada. These changes may affect the loading and cycling of naturally occurring metal(loid)s and the long-term stability of mining-derived ... -
Environmental Characterization of Waste Rock and Tailings from a Carbonatite- Hosted Niobium and Rare Earth Element Deposit
Rare earth elements (REEs) have become essential in green energy and high-tech applications and the development of new REE mines is expected in the coming years. There is currently little published research on the behaviour ... -
Characterization and Age of North-Verging Back Structures in the Tethyan Sedimentary Sequence, Hidden Valley, Central Nepal Himalaya
(2006)Throughout the central Nepal Himalaya, the Tethyan sedimentary sequence (TSS) is structurally dominated by a train of north-verging folds, in apparent contradiction to the dominantly south-propagating Himalayan orogen. The ... -
Provenance, mineralogy, geochemistry, geochronology and Pb isotope systematics of meta-siliciclastic rocks in the Mesoproterozoic Upper Vazante Sequence, Brazil: Implications for metal sources and base metal metallogeny
The objective of this research is to investigate the origin and evolution of meta-siliciclastic rocks within the Mesoproterozoic Upper Vazante Sequence (1300 to 1100 Ma) in order to improve understanding of metal sources ... -
A Stepwise Approach to Verification of the Combined Finite-Discrete Element Method for Modelling Instability Around Tunnels in Brittle Rock
