Abstract In situ analysis of a garnet porphyroblast from a granulite facies gneiss from Sør Rondane Mountains, East Antarctica, reveals discontinuous step‐wise zoning in phosphorus and large δ 18 O variations from the phosphorus‐rich core to the phosphorus‐poor rim. The gradually decreasing profile...
