Fall 2022
In order to understand permafrost and paleoenvironmental conditions in the Mackenzie Delta Region, permafrost cores were collected in the winter of 2017, near the newly developed Inuvik-Tuktoyaktuk Highway (ITH), NWT, by the NWT Geological Survey, NWT Department of Infrastructure, the University...

Controls on organic-rich mudstone deposition: The Devonian Duvernay Formation, Alberta, Canada
DownloadSpring 2016
The Upper Devonian Duvernay Formation of Western Canada is a prolific source rock that in recent years has become an exploration target for shale gas and liquids. Development of the Duvernay Formation has demonstrated the importance of robust models for rock properties such as porosity,...

Stromatoporoid growth forms and Devonian reef fabrics in the Upper Devonian Alexandra Reef System, Canada – Insight on the challenges of applying Devonian reef models.
Download2016-01-01
Existing facies models for Devonian reef systems can be divided into high‐energy and low‐energy types. A number of assumptions have been made in the development of these models and, in some cases, criteria that distinguish important aspects of the models are poorly defined. The Upper Devonian...

Paleomagnetic studies of volcanic rocks in Siberia and sedimentary rocks in Southern Alberta: From long-term geomagnetic field variations to age determinations
DownloadFall 2013
Paleomagnetism is a fundamental tool to understand the ancient variations of Earth’s magnetic field through time. Important applications to geochronology and paleography come from interpreting the variations of the planetary magnetic vector. This dissertation explores the different applications...

The Late Holocene White River Ash East Eruption and Pre-contact Culture Change in Northwest North America
DownloadSpring 2020
The White River Ash East eruption of A.D. 846-848 blanketed portions of Subarctic Yukon and Northwest Territories, Canada in volcanic ash. This dissertation examines impacts of the eruption on pre-contact hunter-gatherer social relationships. The main bodies of data on which interpretations are...

Porosity and permeability in the Graminia Formation, Upper Devonian Winterburn Group in the Germain Field, northeastern Alberta
DownloadFall 2014
The Upper Devonian Graminia Formation (Winterburn Group) found in the Germain Field of northeastern Alberta includes the Blueridge Member (Frasnian) and the Upper Graminia Member (Famennian). A green silty-shale paleosol overlies the formation in this area. The bitumen-bearing dolostones of this...

2002
A series of experiments with an ocean general circulation model of the Mediterranean forced by artificial (but realistic) surface fluxes of heat and freshwater are performed. The model has a stable thermohaline circulation under the baseline fluxes. Small decreases in excess evaporation (8%)...

Expression of Major and Trace Element Signatures of the Frasnian Duvernay Formation within a Sea Level Context: insights into the processes that control mudstone composition, paleoredox conditions and organic matter enrichment
DownloadSpring 2016
This study evaluates the effects of sea level on redox conditions, shale composition and sediment provenance in the Late Devonian (Frasnian) Duvernay Formation of the Western Canada Sedimentary Basin (WCSB) of Alberta, Canada, an organic-rich ‘black’ shale localized between the reefs and...

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...

Study of the Chinese loess and Siberian flood basalts: new global scale insights to the paleoclimate and geomagnetic field changes
DownloadSpring 2017
Paleomagnetism, in conjunction with other earth science methods, studies the behavior of the Earth's magnetic field, the drift of tectonic plate, climate and environmental changes. This thesis implements different applications of paleomagnetism to develop a technique to evaluate age for the...
