Approximately forty, variously shaped, chromitite bodies occur in dunites and harzburgites of the alpine-type peridotite complex of southern New Caledonia. The chromitites consist of pichrochromite (59 to 42% Cr₂O₃) and serpentinized olivine (Fo_96-92) and display a variety of textures (massive, disseminated, and orbicular) consistent with a magmatic cumulate origin. Dunites contain olivine (Fo₉₃₋₉₇) and 1 to 3% picrochromite (50 to 39% Cr₂O₃). Harzburgites have less than 1% spinel, ranging from picrochromite to ceylonite (45 to 28% Cr₂O₃) and often forming symplectic intergrowths with bronzite. Temperatures of crystallization of the cumulate picrochromites are believed to have been about 1200 δC while the more aluminous symplectic spinels equilibrated under different conditions and may reflect a late stage recrystallization episode.
