Lithospheric Structure Across the Northern Canadian Cordillera from Teleseismic Receiver Functions
… of the crust and mantle across the northern Canadian cordillera, described by various tectonic settings. The teleseismic data recorded by broadband three-component seismic stations are used to perform receiver function analysis to determine the lateral variations of Moho depth under northern …

Crustal seismic velocity structure of the intermontane and coastal belts, southwestern Canadian Cordillera
… of LITHOPROBE's seismic program for the Southern Cordillera included a seismic refraction experiment (SCoRE '89) focussing on the Coast and Intermontane Belts of the Southern Canadian Cordillera. Primary objectives of the refraction program include; i) determining 2-D velocity structure and …

Cenozoic Cooling Patterns from the Canadian Cordillera using the Uranium-Thorium-Helium Method
The Cenozoic cooling history of the Canadian Cordillera is important for understanding large-scale processes and relative importance of smaller geologic features. Our study uses the uranium-thorium-helium method, which provides a cooling history for upper crust (~2-6 km). Our data helps resolve …

Distribution of Platinum Group Elements in the New Afton Alkalic Cu-Au Porphyry Deposit, Kamloops, British Columbia
… the eastern part of the Intermontane Belt of the Canadian Cordillera. Bulk rock and sulfide minerals from New Afton contain potentially economic concentrations of platinum group elements (PGE). Primary PGE (Pd ± Pt) enrichment occurs within the main Cu-Au ore body and is spatially associated with …

Characterization of the Fraser fault, Southwestern British Columbia, and surrounding geology through reprocessing of seismic reflection data
… Coast and Inter-montane belts of the southern Canadian Cordillera. Preliminary processing by industry contract and subsequent interpretation revealed several interesting tectonic features; however, the subsurface position and depth extent of the fault were ambiguous. The present study involves …

Geology of the central Moresby Island region, Queen Charlotte Islands, (Haida Gwaii) British Columbia
… the most outboard exposure of Wrangellia in the Canadian Cordillera. This study analyzes the structural and stratigraphic history of the central Moresby Island area, and correlates this history with ongoing and previous studies in the Queen Charlotte Islands. The stratigraphic succession …

Composition and facies variations in mid-cretaceous gates formation coals, Northeastern British Columbia : implications for interpretation of paleo-wetland environments and assessment of coalbed methane characteristics
… Gates peats were deposited east of the rising Canadian Cordillera. This leeward position resulted in drier conditions than the humid climate normally associated with peat formation. Inertinite formed as a result of fires during periodic drought, and was concentrated by preferential destruction …

Crustal velocity structure in the southern coast belt, British Columbia, from a seismic refraction survey
… is one of five morphogeological belts of the Canadian Cordillera. It was created through the complex tectonic processes that accommodated the Mesozoic accretion of the allochthonous Insular superterrane to the Intermontane superterrane, then the leading edge of western North America, and the …

Lithofacies, provenance, and diagenesis of jura-cretaceous strata of the Northern Bowser Basin, British Columbia
… Columbia) record the tectonic development of the Canadian Cordillera. Strata are divided into the undivided Bowser Lake Group and overlying Currier, McEvoy, and Devils Claw formations Lithofacies include marine mudstone, coarsening upward mudstone, fining upward sandstone, coarsening upward …

Trace Elements and Sulfur Isotope Variations in Endowed and Non-Endowed Porphyry Systems of the Dawson Range Mineral Belt, Yukon Territory
The Dawson Range Mineral Belt (DRMB) in the Yukon Territory is a geologically complex region with significant potential for critical mineral exploration. This study addresses the challenges of exploring this area, focusing on select trace elements and sulfur isotope analyses to distinguish between …
