ABSTRACT
The article presents the results of mineral thermobarometry and physicochemical modeling of mineral parageneses in garnet-sillimanite-cordierite gneiss from the Mesoproterozoic metamorphic unit of the Bunger Hills, East Antarctica. Therefore, a clockwise R-T path was inferred using petrograthic and mineralogical data. It is shown that peak temperature of metamorphism could exceed 900 °C. Such temperature conditions in combination with post-peak decompression records the collision-related tectonic evolution of the studied area.
