Summary(Plain Language Summary, not published)
This scientific presentation was given at the Québec Mines 2016, the annual convention of the Ministère de l'Énergie et des Ressources naturelles held in November 2016. The purpose of this contribution was to present preliminary results on the geology and the main field relationships of several mafic and ultramafic intrusions assigned to the Raglan formation of the Cape Smith belt in the northern Québec (Nunavik), through a M.Sc. project. During the 2017 field season, three major types of units have been recognized within the Northern Permits area, located north of the Raglan mine: mafic dominated, ultramafic-dominated, and differentiated mafic/ultramafic. This project aim to characterize the lithofacies and the geochemistry of these mafic and ultramafic units in order to assess the mineral prospectivity of this part of the Cape Smith belt. This contribution is part of a Targeted Geoscience Initiative program of the Geological Survey of Canada.
