Summary(Plain Language Summary, not published)
The Targeted Geoscience Initiative (TGI-4) is a collaborative federal geoscience program that provides industry with the next generation of geoscience knowledge and innovative techniques to better detect buried mineral deposits, thereby reducing some of the risks of exploration. Poster presentation at the GAC-MAC annual meeting held in Winnipeg in May 2013. The poster presents preliminary results from textural, petrographic and geochemical studies done on the gabbroic rocks on the Coppermine Bay intrusion and the Euclid Lake intrusion of the Bird River greenstone belt (BRGB) in southeastern Manitoba. The results suggest that CBI and ELI exhibit similar charasteristics and that both intrusions are comparable to other mafic-ultramafic intrusions of the BRGB supporting the interpretation that these intrusions are linked to a wide spread magmatic event identified as the Bird River intrusive event.
