The Central Indian Precambrian Shield (CIPS) has evidenced extensive late to post-tectonic granitic activity in the Early Proterozoic time. This is evidenced by plutonic rocks of batholithic dimensions occurring in the areas e.g. Bundelkhand, Dongargarh, Malanjkhand, etc. Dongargarh granite (DG) massif and the Malanjkhand granite (MG) represent a widespread late to post-tectonic plutonic event at 2.3 ± 50 Ga. Distance between these two granite pluton is 150 km. Rb vs Sr relation studied with the assumption that the densities (2.8) of the rocks remain unchanged with the depth and also the pressure increases regularly with the depth. DG has crystallized at slightly lower depth (25 to 30 km) than the MG (30 to 35 km). The probable temperature of crystallization is calculated for both the rates - 1 °C I 30 meter and 1 °c I 40 meter and the temperature for DG are 832°C to 999°C & 625°C to 750°C. Similarly for the MG the temperature are for both geothermal gradient, 999°C to 1165°C & 750°C to 875°C respectively. Key words: Dongargarh, Malanjkhand, Granitoids.
