This Geologists show much interest in recent years to high-grade metamorphic rocks and particularly on granulites of southern peninsular India. Granulite shows preservation of near peak metamorphic mineral assemblages and minerals developed during retrograde metamorphism. The recent studies of fluid inclusions from the South Indian granulites have shown that CO2-rich inclusions are the common fluid species present in these rocks (Newton, 1989; Santosh et al., 1991; Srikantappa et al., 1992, Touret, 1971). Though now generally agreed those carbonic fluids are the dominant fluids present in South Indian granulites and in some parts of eastern ghat granulites (Srikantappa and Bhaskar Rao, 1995). The problem is whether these fluids are syn-metamorphic or postmetamorphic with respect to peak metamorphic conditions of charnockite granulite.
