Supplementary Fig. S2. Cr2O3 (wt.%) vs. CaO (wt.%) plot for garnets from dyke 1 by new data (a) and after Egorov et al. 2005 (b). Composition fields G0–G12 separated by solid lines after Grutter et al. 2004: G0 – unclassified garnets; G1 – pyrope garnet megacrysts; G3 – eclogitic garnet; G4–G5 – pyroxenitic and websteritic low-Cr (G4) and high-Cr (G5) garnets; G9 = lherzolitic garnet; G10 = harzburgitic garnet; G12 = wehrlitic garnet. Garnet compositional fields separated by dashed lines correspond to different mantle paragenesis (after Sobolev et al. 1971, 1973): 1 – diamond dunite-harzburgitic, 2 – dunite-harzburgitic, 3 – lherzolitic, and 4 – vherlitic parageneses.
