Melting of San Carlos Olivine in the Presence of Carbon at 6-12 GPa

Fig.5. Temperature-pressure phase diagram for the composition . The geotherm was constrained at low pressures by the thermobarometry (Gasparik 2000) applied to mantle xenoliths from Northern Lesotho(Nixon and Boyd 1973), and at the lower-mantle pressures by the thermobarometry (Gasparik and Hutchison 2000) applied to the NaPx-En (Wang and Sueno 1996) and the Type III (Hutchison 2000) inclusions in diamonds. Symbols are the same as in Fig. 5; fPc = ferropericlase, (Mg,Fe)O
