The Pinède Grise Pluton is a new unit introduced by Leclerc and Caron-Côté (2017).

The Pinède Grise Pluton is mainly composed of medium to coarse-grained granite pinkish gray to beige in altered surface and medium pinkish gray in fresh exposure. Granite has a massive and equigranular structure, but locally develops a foliation. It contains 1 to 3% biotite and can include up to 2% magnetite. Hematite and epidote are the most common alteration minerals. The Pinède Grise Pluton contains a minor proportion of medium-grained biotite magnetite monzonite and porphyritic monzodiorite with K-feldspar, biotite and hornblende phenocrysts. The unit is commonly cut by granitic pegmatite intrusions and contains xenoliths of foliated to gneissic diorite.
