Ilmenite
Layers of apatite, magnetite, and ilmenite-rich gabbro also occur in the Sept Iles intrusion in Quebec (Namur et al., 2010, 2012). Other ilmenite-rich deposits may be essentially massive oxides (e.g., the Big Island massive hemo-ilmenite dike that crosscuts the Allard Lake anorthosite) and their origins are controversial (see below).

The largest and most important is the Lac Tio deposit. The deposits of the Lac Allard region contain ilmenites of similar composition. The Allard Lake ilmenite deposits lie in the northeastern part of one of the large Precambrian anorthosite masses and comprise a series of metamorphic and igneous rocks that belong to the Grenville Province.
