Timing of metamorphism in the central Sør Rondane Mountains, eastern Dronning Maud Land, East Antarctica: Constrains from SHRIMP zircon and EPMA monazite dating

► Two metamorphic events recognized in the Sør Rondane Mountains. ► Granulite-facies metamorphism related to main collision took place at ca. 600-640 Ma. ► Amphibolite-facies metamorphism resulted from igneous activity at ca. 520-570 Ma.
