Newly discovered orthopyroxene and clinopyroxene megacrysts (OPMs and CPMs) in the Labrieville massif provide additional constraints on megacryst origins and their sig­nificance in massif anorthosite petrogenesis. Pyroxene megacrysts (∼ 1-15 cm across) oc­cur throughout the anorthosite, some in layered zones (as cumulates?) and others as scat­tered crystals that form subophitic intergrowths with plagioclase; some also contain tabular plagioclase inclusions. In many cases, pyroxene megacrysts are intergrown with ilmenite and locally occur within meter-sized masses of ilmenite. Plagioclase and ilmenite are the dominant exsolution products in OPMs, whereas CPMs contain additional lamellae of orthopyroxene. Biotite consistently occurs with megacrysts, locally as an integral portion of exsolution lamellae.
