Probing the Mantle Cargo of Kimberlites – A Geochemical Investigation of Different Mineral Components and Evaluation of their Potential as Petrogenetic and Exploration ToolsDownload
This thesis applies microanalytical tools to the geochemical investigation of different mineral components in the volcanic rock kimberlite. This work significantly advances the application of one of these tools, deep UV (193 nm) laser ablation inductively coupled plasma mass spectrometry...
187Re-187Os analysis of magnetite and other oxide minerals from various well dated geological settings (kimberlites, lamprophyres, Manicouagan impact melt rock, Great Bear magmatic zone iron ore deposits and Laramie Anorthosite complex) worldwide have been used to investigate the potential for...
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...
The composition of primary kimberlitic melts has been the subject of much debate because of the heterogeneous nature of kimberlites, their ubiquitous modification by mantle and crustal contamination, their high susceptibility to alteration during and after emplacement, and the fact that the melts...
The Quandary of the Sask Craton: Origin and Evolution of the Lithospheric Mantle beneath the Sask CratonDownload
Mantle xenoliths from the Cretaceous (~106 to ~95 Ma) kimberlites at Fort à la Corne (FALC) present a unique opportunity to study the lithospheric mantle beneath the newly recognised Sask Craton. The Sask Craton, a small terrane with Archean (3.2 - 2.5 Ga) crustal ages, is enclosed in the...
The aluminum-in-olivine thermometer for mantle peridotites — Experimental versus empirical calibration and potential applicationsDownload
This study provides an experimental calibration of the empirical Al-in-olivine thermometer for mantle peridotites proposed by De Hoog et al. (2010). We report Al concentrations measured by secondary ion mass spectrometry (SIMS) in olivines produced in the original high-pressure, high-temperature,...
The evolution of calcite-bearing kimberlites by melt-rock reaction: evidence from polymineralic inclusions within clinopyroxene and garnet megacrysts from Lac de Gras kimberlites, CanadaDownload
Megacrystic (>1 cm) clinopyroxene (Cr-diopside) and garnet (Cr-pyrope) xenocrysts within kimberlites from Lac de Gras (Northwest Territories, Canada) contain fully crystallized melt inclusions. These ‘polymineralic inclusions’ have previously been interpreted to form by necking down of melts at...
