This report serves as a progress report on the fieldwork, map compilation and geoscience research undertaken in the GEM-2 North Baffin bedrock mapping activity in late 2016 and 2017, as part of GEM-2 Baffin Project.
Geological maps inform industry, government, and community stakeholders of potential economic resources. During the past two decades, systematic and targeted mapping of Precambrian and Phanerozoic bedrock geology has been completed for large tracts of Nunavut. Updated regional bedrock map coverage for Baffin Island south of latitude 70°N was completed in 2016 (St-Onge et al., 2016). The activity described herein represents the first steps towards an updated geological framework north of 70°N, with the goal of producing maps at a scale and resolution commensurate with those produced for the southern portion of the island.
Improved geological maps will help determine the potential for diamonds, base metals and carving stone in northern Baffin Island. The area covered by the 2017 fieldwork (NTS sheet 37G, and 38B not including Bylot Island) includes the world-class Mary River iron mine operated by Baffinland Iron Mines Corporation. The hamlet of Pond Inlet is located along the northern coast of the study area, making it relatively easy to access for potential exploration work. The study area also includes portions of Sirmilik National Park, and in line with the mandate of Parks Canada, an updated geological knowledgebase for the park will benefit future generations of Canadians and park visitors.
Summary(Plain Language Summary, not published)
This report serves as an update on the fieldwork and map compilation activities undertaken as part of the GEM-2 North Baffin bedrock mapping project during 2017. As shown in previous GEM projects, improved geological maps help determine the mineral potential of remote areas of Canada. The occurrence of a world-class, currently producing iron deposit in the area (Mary River), makes the geology of northern Baffin Island particularly interesting for other mineral occurrences.
