We report the reaction microstructures observed in the corundum-bearing UTH granulites from the migmatite zone occurring near the western boundary of the Eastern Ghats Belt (EGB), India.
This study helps to identify different stages of metamorphic evolution, which relates to the tectonic evolution of the western margin of EGB.
In this presentation, we report in detail the mineral assemblages, reaction microstructures and metamorphic conditions for each metamorphic stage.
