Magnesian metapelites of probable Archaean age from Forefinger Point, SW Enderby Land, East Antarctica, contain very‐high‐temperature granulite facies mineral assemblages, which include orthopyroxene (8–9.5 wt% Al 2 O 3 )–sillimanite ± garnet ± quartz ± K‐feldspar, that formed at 10 ± 1.5 kbar and 9...
