    Abstract

    New analyses of a garnet-clinopyroxene rock ('eclogite') and its constituent minerals from the Sittampundi complex of India are presented. The rock has a composition comparable with an alkali- poor tholeiite and this composition, as well as the garnet and pyroxene are very similar to those from South Harris. The apparent distribution coefficient for the garnet-clinopyroxene pair suggests a temperature of equilibration near 850 C. Projection of the experimental data of Green and Ringwood (1967) down to this temperature suggests a pressure of about 7 to 8 kbar. This is well below the pressure of the granulite-eclogite transition.
