Titanomagnetite
At the Damiao deposit several discordant ore bodies are present, hosted by anorthosite and leuconorite. Titaniferous magnetite is the primary ore mineral at Damiao, but an ilmenite±apatite assemblage is also common. Layers of apatite, magnetite, and ilmenite-rich gabbro also occur in the Sept Iles intrusion in Quebec (Namur et al., 2010, 2012 ...
