Age, geochemistry, and fluid characteristics of the MAX porphyry Mo deposit, southeast British ColumbiaDownload
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....
Age, origin and composition of the Attawapiskat lithospheric mantle and its diamonds (western Superior craton, Canada)Download
This study reports results from peridotitic and eclogitic xenoliths and di- amond samples from the Attawapiskat area to understand the processes of craton formation and modification in the Superior lithospheric mantle. These diamondiferous kimberlites also provide an opportunity to study the...
Further Re-Os Arsenopyrite Geochronology from Selected Meguma Au Deposits, Meguma Terrane, Nova Scotia: Possible Evidence for a Protracted Gold-forming SystemDownload
The Meguma terrane, Nova Scotia, is dominated by two rock types; regionally deformed and metamorphosed Cambro-Ordovician metasedimentary rocks and ca. 380-370 Ma meta- to peraluminous granites. The metasedimentary rocks host numerous orogenic-type, vein-hosted gold deposits which occur throughout...
Geochronology and Trace Element Characteristics of Pyrite from Selected Carbonate Hosted Pb-Zn Ore DepositsDownload
Carbonate-hosted ore deposits, such as Mississippi Valley-type (MVT), and Irish-type deposits, are a major class of Pb-Zn ores. Due to the mineralogy of these deposits, numerical constraints on the timing of mineralization are few. This thesis investigates pyrite Re-Os geochronology for dating...
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...
The 1.9 Ga Winnipegosis Komatiite: Implications for Earth Accretion, Mantle Dynamics, and Komatiite FormationDownload
Komatiites are high temperature, high MgO lavas that have the potential to provide geochemical and thermal insights into the evolution of the Earth's mantle. However, komatiite studies are frequently hampered by the altered nature of all komatiites and the presence of large gaps in the komatiite...
The Age and Origin of Lithospheric Mantle Beneath Central Victoria Island and Parry Peninsula, Northern CanadaDownload
New mineral major and trace element chemistry, bulk rock major element chemistry plus bulk rock and olivine PGE-Re-Os isotope data are presented for kimberlite-borne mantle xenoliths from Central Victoria Island, Nunavut and Parry Peninsula, Northwest Territories. The data, along with new and...
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...
