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 is to present a petrographic and geochemical characterization of several mafic and ultramafic intrusions assigned to Montagnais sills in the northern part of the Labrador Trough (Québec), through a M.Sc. project. Three types of intrusions, belonging to a tholeiitic magma series, were identified in the study area: 1) mafic-dominated, 2) ultramafic-dominated and 3) ultramafic to mafic differentiated. Using collected and available data, a new geological map is also presented in this contribution. This project is part of a collaborative effort under the GEM-2 program between the Geological Survey of Canada and the Ministère de l'Énergie et des Ressources naturelles du Québec to better characterize and understand the mineral potential of these mafic and ultramafic intrusions in the Labrador Trough.
