The Character And Distribution Of Cu-Pge Mineralization At The Geordie Lake Deposit Within The Coldwell Complex, Ontario, Imran Meghji

Electronic Thesis and Dissertation Repository

Cu-PGE mineralization at the Geordie Lake Deposit (GLD) is spatially associated with weak to intense actinolite and albite alteration within gabbro and troctolite. Previous studies have determined a magmatic, and magmatic-hydrothermal origin of the deposit. The most significant Cu-PGE occurrence in the GLD is dominantly stratiform, and in contact with a basal syenite. Similar patterns of REE with progressive enrichment from troctolite, to gabbro, and basal syenite indicate that these lithologies are genetically linked. Major element geochemistry shows no discernable variation between the altered and unaltered samples. Whole rock δ¹⁸O analyses were conducted in equal intervals down the …
