Geochemical Constraints on Granulites of the Central Indian Shield: Key Insights into Crustal Evolution

Granulites are significant rocks that are eminent by distinct factors. One of the vital factors is that these rocks are counterparts of middle and lower crustal rocks because they are ready for fairly rational pressure-temperature estimation, existing on the borderline between melting and metamorphism. In the central Indian shield, the granulite belts commonly occur along the shear zones within the Central Indian Tectonic Zone (CITZ). The CITZ is a collage of different granulite belts, including Bhandara-Balaghat Granulite (BBG), Ramakona Katangi Granulite (RKG), and Makrohar Granulite (MKG) belts from south to north, which correspond to a multiphase orogenic evolution during Late Paleoproterozoic to Early Neoproterozoic time. Previously, numerous investigations were carried out in the central Indian shield, which are majorly refrained based on phase equilibria, thermobarometry, and metamorphic reactions. Geochemical and geochronological data sets may indicate that the granulite and granitic magmatism connected with the acidic magmatism during the Columbian crustal assembly
