Objectif(s): To develop a modern geological, crustal architecture and exploration framework for polymetallic iron oxide-copper-gold (IOCG) deposit-type mineralizing systems in the Great Bear magmatic zone and new exploration methods for IOCG deposits in glaciated terrains
Description du projet: The objectives of the Great Bear/IOCG geoscience research and mapping project are to: • develop a modern geological, crustal architecture and exploration framework for polymetallic iron oxide-copper-gold (IOCG) deposit-type mineralizing systems in the Great Bear magmatic zone and new exploration methods for IOCG deposits in glaciated terrains; • validate deposit-type model for known mineral occurrences, identify new mineralizing systems in virgin territories, clarify the mineral potential of the belt, provide new exploration opportunities and catalyze discovery of other IOCG settings in the North; • refine knowledge of the geological parameters and processes that potentially control mineralization and distribution of deposits along the belt, and advance nationally and internationally the formulation of IOCG deposit models; • train a new generation of Canadian geoscientists to sustain emerging IOCG exploration in Canada's North and extend that training to some First Nations youths; • provide a solid geoscience basis for informed land use planning in Tlicho and Sahtu lands also taking into account the geology of their cultural heritage; • engage northern youths in science activities and ensure that project benefits northern development, Northerners, the Canadian mineral industry and Canadians in general. During summer 2010 a high-resolution magnetotelluric survey was conducted over the NICO deposit. A two-person team installed 3 magnetometers and 5 electrodes at each site they visited (approximately 4 to 5 per day). The magnetometers were placed in shallow (about 1 foot deep) trenches about 5 feet long and 6 inches wide. The electrodes will be installed in 1 foot deep cylindrical holes about 1 foot across. After one or two nights of data collection the equipment was removed. Paleomagnetic studies and rock physical properties on the NICO deposit and surrounding rocks were also conducted with hand held instruments. No gravity profiles were conducted. The researchers may attempt to conduct one in 2011. If it happens it will simply involve measurements in the field with a hand held instrument as for the magnetic and radiometric ground profiles. The researchers are starting to publish results of the project in the form of technical scientific papers, short course notes and maps. These products are available upon requests to project leader, Louise Corriveau at lcorrive@nrcan.gc.ca. Publication of outreach material such as the slides of outreach talks presented at various conferences and meetings are being updated and will be review and then published. Some may be released as open files before March 31st, 2011. The fieldwork for this study will be conducted from June 13, 2011 to August 26, 2011.
