A highly residual granulite facies rock (sample RG07-21) from Lunnyj Island in the Rauer Group, East Antarctica, presents an opportunity to compare different approaches to constraining peak temperature in high-grade metamorphic rocks. Sample RG07-21 is a coarse-grained pelitic migmatite composed of...
