Age, composition and thermal history of lower crustal xenoliths from the Artemisia, Ekati and Munn Lake kimberlites of the Slave Craton
DownloadSpring 2015
In this study we present data from three lower crustal xenoliths suites collected in a northeast to southwest transect across the Slave craton. The samples are from the Artemisia kimberlite, located near the Coronation diamond district of the northwestern Slave (Nunavut), the Ekati kimberlite...

Temperatures and Heat Production in the Slave Craton Lower Crust: Evidence from Xenoliths in the Diavik A-154 Kimberlite
DownloadFall 2019
Lower crustal heat production is poorly constrained due to the relative inaccessibility of lower crustal samples and their inherent complexity. To obtain the requisite information, the current project conducts spatially resolved geochemical analyses on minerals in 15 lower crustal xenoliths...

Fall 2009
The oxidation state, reflected in the oxygen fugacity (fO2), of the lithospheric mantle is both laterally and vertically heterogeneous. Depth-fO2 profiles from kimberlite-borne peridotitic mantle xenoliths from the Bultfontein kimberlite, Kimberley, South Africa and the A154-N and A154-S...

The physical and geochemical characteristics of diamonds from the Artemisia Kimberlite (Northern Slave Craton, Nunavut, Canada) and the micro-/macro-diamond relationship
DownloadFall 2011
This thesis presents the results of a study on diamonds from the Artemisia kimberlite, Nunavut, Canada. This study integrates the isotopic, chemical and physical characteristics of the diamonds in an attempt to provide insight into the nature of the micro-/macro-diamond genetic relationship, and...
