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...

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,...

Age, geochemistry, and fluid characteristics of the MAX porphyry Mo deposit, southeast British Columbia
DownloadFall 2009
Lawley, Christopher John Michael
MAX is a porphyry Mo deposit located near Trout Lake village in southeastern British Columbia. Mo mineralization is hosted by variably-altered calc-alkaline granodiorite dikes. Quartz veins have been subdivided into a paragenetic sequence based on vein style and crosscutting relationships....

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...

Characterization of late-diagenetic calcites of the Devonian Southesk-Cairn Carbonate Complex (Alberta Basin): constraints from petrography, stable and radiogenic isotopes, fluid inclusion and organic matter maturity data
DownloadSpring 2010
The Alberta Basin has been the subject of various diagenetic studies but the precise understanding of the processes behind deep burial cementation remains unclear. This study investigates late-diagenetic calcites from the Devonian Southesk-Cairn Carbonate Complex with the purpose of constraining...

Ediacaran iron formations and carbonates from Uruguay: palaeoceanographic, palaeoclimatic and palaeobiologic implications
DownloadFall 2010
The Ediacaran in Uruguay preserves a unique record of deposits generated during the assembly of the palaeocontinent Gondwana and concurrent with major changes in the atmosphere and oceans, and the rise of animal life. Recent studies have suggested that the deep oceans remained anoxic and highly...

Spring 2010
Carbon isotope analyses of gases extracted from drilling muds while drilling in the Western Canada Sedimentary Basin (WCSB) can be used to create carbon isotopic depth profiles. These profiles provide essentially continuous data through the stratigraphic section, offering a unique opportunity to...

Geology and geochemistry of late Devonian-Mississipian sediment-hosted barite sequences of the Selwyn Basin, NWT and Yukon, Canada
DownloadFall 2011
A sediment-hosted barite horizon occurs in the upper part of the lower Earn Group in the Selwyn Basin, NWT, Canada. This horizon consists of synsedimentary, laminated barite and diagenetic, nodular barite which are hosted in shale, siltstone and mudstone. The lithogeochemistry of the sediments...

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 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...
