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, ... -
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
Numerical modelling of excavations in rock has advanced considerably in recent decades. While continuum numerical models form their basis in methods which can be verified by analytical solutions, discontinuum and hybrid ... -
Impact of Long- and Short-Term Geodynamic Processes on Hydrocarbon Reservoirs in the Grand Banks
The evolution of the passive margin off the coast of Eastern Canada has been characterized by a series of rifting episodes beginning approximately 200 ma which caused widespread extension of the lithosphere and associated ... -
Improvement of Laboratory Protocols for Discontinuity Geomechanical Characterization and Investigation of the Effect of Saturation on Granite Strength
The Nuclear Waste Management Organization of Canada (NWMO) is currently in the process of site selection for the future development of a high-level nuclear waste Deep Geological Repository (DGR), and locations with crystalline ... -
Characterization of Arsenic Hosting Phases in Subaqueous Tailings at Terra Mine, Northwest Territories, Canada
Over the lifetime of operations at Terra Mine, an abandoned silver-copper mine in the Northwest Territories, an estimated 500,000 tons of tailings containing 540,000kg of arsenic (As) were deposited into Ho-Hum Lake. Arsenic ... -
Application of Molybdenum and Thallium Isotopes as Indicators of Paleoredox Conditions and Genesis of Hyper-Enriched Black Shale (HEBS) Deposits, Peel River, Yukon
Hyper-enriched black shale (HEBS) deposits, such as those hosted in Devonian black shales of northern Yukon, are a globally significant source of a variety of economically important metals, particularly nickel, copper, ... -
Application of Pyrite Mineralogy and Chemistry to Determining Paleoredox, Hydrothermal History, and Target Vectoring in the MacMillan Pass Sedex District, Yukon, Canada
The MacMillan Pass district in Yukon, Canada, hosts the Tom and Jason sedimentary exhalative (SEDEX) Pb-Zn-Ag-(Ba) deposits. Pyrite-bearing drill core samples were collected from seven drill holes that intersected ... -
Arsenic concentrations and solid phase speciation in soils in the Yellowknife region
Roasting of gold-bearing arsenopyrite (FeAsS) ore at mines around Yellowknife resulted in the release of arsenic trioxide (As2O3) via airborne emissions. Previous studies highlighted a persistent elevated arsenic (As) in ... -
Geochemical and mineralogical characterization of arsenic in lake sediments impacted by legacy gold mining in the Yellowknife region
Arsenic concentrations in lake sediments in the Yellowknife region, Northwest Territories, Canada are elevated from the weathering of mineralized bedrock and/or from the mining and processing of arsenic (As)-bearing ores ... -
Evaluating the Surficial Geochemical Expressions in Soil, and Tree Cores Surrounding an LCT Pegmatite at Pakeagama Lake, Ontario
The Pakeagama Lake Pegmatite is a complex type, petalite subtype Li-Cs-Ta (LCT) pegmatite, located in Northwestern Ontario, Canada, at the border of the Berens River and Sachigo subprovinces of the Archean Superior ... -
Assessing the Contributions of Remote Sensing Data in Geological Site Investigations
Unforeseen ground conditions can have significant impact on the success of any geological project. Therefore, geological site investigation is an essential component of geological field campaigns. Remote sensing techniques ... -
Protolith Affiliation and Tectonometamorphic Evolution of the Gurla Mandhata Core Complex, NW Nepal Himalaya
Migmatite-cored gneiss domes in the Himalaya are valuable structures that expose the mid-crust, allowing for the investigation of tectonic and structural processes governing the evolution of the Himalayan orogen. Located ... -
Paragenesis of Gold Mineralization and Integrated Exploration Techniques of the Kiyuk Lake Project, Kivalliq Region, Nunavut, Canada
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 ...
