“…A large number of geothermometric studies exist for Group C eclogites, generally utilizing the Ellis and Green (1979) calibration of the garnet -clinopyroxene Fe -Mg exchange equilibrium. Group C eclogites from California (e.g., Moore, 1984;Oh and Liou, 1990), Alaska (Patrick and Evans, 1989), Venezuela (Maresch and Abraham, 1981), Western Alps (e.g., Ernst and Dal Piaz, 1978), Cyclades (e.g., Schliestedt, 1986), Turkey (Okay, 1989b;Okay and Satır, 2000) and Oman (e.g., El-Shazly et al, 1990) give consistent temperature estimates of 500 F 50 jC at 10 -15 kbar pressure range. These temperature estimates are similar to those from omphacite -garnet contacts in the eclogite sample, and a temperature of 500 F 50 jC at 10-15 kbar pressure range can be assumed for the Muttalip eclogite.…”
