Abstract Late Archaean orthogneisses and aluminous and iron‐rich metasedimentary rocks intruded by anorthosite and a ferrodiorite‐granite suite were completely recrystallized during Proterozoic granulite facies metamorphism. Geobarometry and geothermometry indicate P‐T conditions of around 7.5kbar....
