| 抄録 | The geology of Ganguvapatti area situated at the central Madurai block of southern India consisting of varous high-grade metamorphic rock types. This contribution briefly describes the geology, field occurrences and petrography of metamorphic rock from Ganguvarpatti area. Ganguvarpatti is known for its occurrence of sapphirine-bearing UHT granulites while the surrounding granulites are less studied. So in this contribution we have discussed the pressure-temperature stability and evolution of granulites surrounding UHT granulites. The pressure-temperature estimation of garnet-orthopyroxene-cordierite granulite resulted a near peak temperature condition of>950゜ C at a pressure between 9-10 kbar. These results are in good agreement with the stability field in the KFMASH petrogenetic frid.
