Large charnockite plutons (∼970 Ma) were intruded into high-grade metamorphic rocks of the Mawson Coast area, east Antarctica, immediately after peak granulite metamorphism in the region. Detailed Sr-Nd isotopic studies suggest that charnockites in the central zone have significantly higher initial...
