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,...

Environmental Controls on Alternating Aragonite-calcite Laminations in Notch-speleothems from Cayman Brac, Cayman Islands, British West Indies
DownloadFall 2017
Speleothems that grow in semi-exposed surface environments, such as wave-cut notches, are not well understood despite their widespread distribution. The +6.4 m-high wave-cut notch on Cayman Brac, that formed ~ 125 ka ago, is decorated with stalactites, stalagmites, and columns that grew between...

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...

Spring 2023
Centennial, millennial and multi-millennial scale climate cycles have been observed in paleoclimate proxies distributed globally. Examples of these cyclical climate cycles include oscillations with periods of ~2.3, ~1.5, ~1, and ≤0.5 thousand years (kyr) in the Quaternary. In the Neogene, longer...

Paelomagnetic and petromagnetic studies of Chinese Cenozoic sediments: Paleoclimatic, tectonic, and evolutionary implications
DownloadFall 2012
The anisotropy of magnetic susceptibility (AMS) was investigated in three Chinese Loess Plateau sedimentary sections along a W–E transect. Previously published models assumed that winter monsoons were responsible for the magnetic fabric formation of loess sequences. In our new interpretation, the...

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...

Sequence Stratigraphy, Porosity, and Primary Producers of the Middle to Late Devonian Canol Formation, Northwest Territories, Canada
DownloadFall 2022
The Devonian Canol Formation of the Northwest Territories (NWT) is an organic-rich mudstone interval deposited in a tropical marine setting along the west coast of Ancestral North America. This unit preserves a record of local marine conditions in the Middle to Late Devonian, a time characterized...

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...

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...

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...
