Petrogenesis of the Moose Lake Area of the Acasta Gneiss Complex, Slave Craton, Northwest Territories, Canada
DownloadSpring 2021
The Acasta Gneiss Complex (AGC) is a late Hadean to early Archean terrane in northwestern Canada known to contain the oldest evolved rocks on Earth. However, only a small portion of the AGC has been studied in detail. This study aims to explore one of the poorly explored portions of the AGC, the...

Polar bear (Ursus maritimus) foraging, spatial, and energetics ecology in the changing Arctic
DownloadFall 2020
Climate warming in the Arctic has resulted in rapid and extensive changes to sea ice dynamics and profound ecological impacts, including changes to the timing of life history events, community structure, and food web dynamics. Sea ice-dependent species such as polar bears (Ursus maritimus) are...

Sedimentology, diagenesis, and dolomitization of the Brac Formation (Lower Oligocene), Cayman Brac, British West Indies
DownloadFall 2009
The Oligocene Brac Formation is the oldest part of the Bluff Group that is exposed on Cayman Brac. Sediments of the Brac Formation were deposited on a small, open bank in shallow marine waters. Today, the formation is composed of limestone, finely crystalline dolostone, and coarsely crystalline...

Stratigraphy, paleogeography and tectonic evolution of early Paleozoic to Triassic pericratonic strata in the northern Kootenay Arc, southeastern Canadian Cordillera, British Columbia
DownloadSpring 2013
The northern Kootenay Arc in southeastern British Columbia hosts a near-continuous succession of Cambrian to Permian strata that were deposited in overlapping marginal basins outboard of the Canadian Cordilleran miogeocline. The basinal strata of the Late Cambrian and younger Lardeau Group are...

Stratigraphy, petrography and geochemistry of the Bad Heart Formation, Northwestern Alberta
DownloadSpring 2011
Bad Heart Formation oolitic ironstone is the largest resources of iron in western Canada. During this study, 45 new sections from outcrop, trench and drill holes were mapped, and 325 samples were collected for petrographic and geochemical analysis. The objective of the first paper is to refine...

The genesis of the Gayna River carbonate-hosted Zn-Pb deposit
Fall 2009
Geochemical analyses on samples from the Mississippi Valley Type Gayna River deposit, Northwest Territories, Canada, have resulted in the definition of three ore stages and a deposit genesis model. Pb/Pb and Re/Os isotopic analyses indicate that the mineralization at Gayna River was emplaced...

The origin and evolution of eclogite xenoliths and associated diamonds from the Jericho kimberlite, northern Slave craton, Canada: an integrated petrological, geochemical and isotopic study
DownloadFall 2011
Diamond-bearing eclogite xenoliths are relatively rare but provide insight into the composition and evolution of the cratonic lithospheric mantle and also insight into the diamond formation process. The major-, trace-element and Sr-Pb-O-isotope compositions of both high- and low-MgO diamond...

Fall 2009
Recent discoveries of kimberlites in North America have revealed that different processes are involved in the generation of kimberlite magma. A multi-disciplinary approach combining mineralogical, petrological, geochemical, and geochronological methods is used to classify the kimberlites,...

The Quandary of the Sask Craton: Origin and Evolution of the Lithospheric Mantle beneath the Sask Craton
DownloadFall 2018
Mantle xenoliths from the Cretaceous (~106 to ~95 Ma) kimberlites at Fort à la Corne (FALC) present a unique opportunity to study the lithospheric mantle beneath the newly recognised Sask Craton. The Sask Craton, a small terrane with Archean (3.2 - 2.5 Ga) crustal ages, is enclosed in the...

The Structure and Dynamics of Fish Isotopic and Trophic Niches in Natural Lakes and Constructed Fisheries Offsets in the Alberta Oil Sands
DownloadFall 2022
Habitat offsets, where damages to natural ecosystems caused by socio-economic development projects are compensated for by the construction or restoration of other ecosystems, can contribute to biological conservation when implemented properly. But, large uncertainties remain surrounding our...
