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...

Geochemistry and source-tracing of the Sparrow Dyke Swarm, the Tsu Lake dykes, the Martin Group Igneous Rocks and the Christopher Island Formation
DownloadSpring 2012
The present study has determined that tholeiitic basalt dykes, trending 130, found near Tsu Lake, NT, are geochemically similar to the Sparrow Dyke Swarm (McGlynn et al., 1974). Geochemically, the correlation of the calc-alkaline basalts of the Martin Group Igneous Rock (MGIR) with the Sparrow...

Geology, geochronology, thermobarometry, and tectonic evolution of the Queen Maud block, Churchill craton, Nunavut, Canada
DownloadSpring 2012
The Queen Maud block is divided into two crustal belts. The western Perry River belt is dominated by Mesoarchean to Neoarchean granitic gneisses and supracrustal rocks; it was incorporated into the Rae domain by at least 2.46 Ga. The eastern Paalliq belt is dominated by the 2.52-2.45 Ga Queen...

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...

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...

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...
