1. Fig. 5. Compositions of orthopyroxene plotted as wt % Cr₂O₃ vs CaO for: 1, spinel–garnet coarse peridotite; 2, garnet coarse peridotite; 3, porphyroclastic non-disrupted peridotite; 4, porphyroclastic disrupted peridotite; 5, megacrystalline pyroxenites; 6, megacrysts. Continuous lines delineate fields of characteristic chemical compositions for the above rock types.
