We are reporting a new locality of calc-granulite from the Baradgatta area of the Makrohar granulite belt including the mineral assemblage garnet – clinopyroxene – plagioclase – sphene - clinozoisite. The Makrohar granulite belt (MKG) is located northwest extension of the chotanagpur granite gneiss complex along the northern margin of the central Indian tectonic zone. A peak pressure condition of 5.24 kbar at 600 °C is obtained from Grt-Cpx-Pl-Qz barometers and the estimated temperature is 675 °C at 7 kbar. The average P–T condition of metamorphism of granulite formation is at 624 ± 97 °C and 5.6 ± 0.8 kbar. The formation of stable mineral assemblages such as (Grt-Cpx-Sph-Cz-Pl) in the NCFMAST-HC model system is suitable within the temperature range of 620-635°C at (XCO2> 0.4).
