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 ... -
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 ...
