Summary(Plain Language Summary, not published)
Regional bedrock geological mapping and compilation of surface exposures and diamond-drill core was carried out between 2010 and 2014 in the 'Ring of Fire' (RoF) region as part of the Ontario Geological Survey's core bedrock geology mapping program and the Targeted Geoscience Initiative of the Geological Survey of Canada. The RoF region has been subdivided in 1:100 000 scale geological maps (northern, central, southern sheets). This geological map summarizes the field observations and the compiled information acquired during the field campaigns in the McFaulds Lake area. The most prominent feature depicted on the maps is the McFaulds Lake greenstone belt, an extensive (>200km long), arcuate-shaped, Meso- to Neoarchean, greenstone belt located in the central part of the Oxford-Stull domain of northern Ontario. All rocks record a history of episodic volcanism, sedimentation, ultramafic-felsic intrusive activity and tectonism spanning from at least 2.83 to 2.66 Ga. The maps also display the distribution of mineral occurrences and a summary of U-Pb ages from the region.
