Geochemistry of diamonds and their mineral inclusions constraining the composition of the lithospheric mantle and recycling of crustal materials
DownloadFall 2022
Bimineralic eclogite xenoliths from Koidu have been extensively studied previously, but less attention has been directed towards diamondiferous eclogite xenoliths as well as eclogitic and peridotitic diamonds from this locality. To gain insight into the geologic history of the lithospheric mantle...

Different laser ablation and mass spectrometry techniques and FTIR spectroscopy have been used to investigate elemental impurities, defects, and stable and radiogenic isotope compositions in natural diamond and ruby, with the aim of expanding previous research into diamond and ruby genesis,...

This report describes the methods and samples utilized (to 2014) within the Canadian Centre for Isotopic Microanalysis (CCIM), University of Alberta, for routine analysis of δ13CVPDB, δ15NAIR, and N abundances of diamonds by secondary ion mass spectrometry (Cameca IMS 1280). Analyses by...

Rockbursts have been a hazard for mining operations since underground mining first came into practice; the consequences they present to mining personnel and machinery can be fatal and costly. Underground mining in Northern Canada has presented the opportunity to study the bursting properties of...

Gahcho Kué is a diamond mine in the Northwest Territories of Canada that opened in 2016. This is the first study into the morphology, N systematics, and stable isotope (C and N) composition of the Gahcho Kué diamonds, and the mineral chemistry of the associated inclusions. The resulting data are...

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 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...

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...
