Osumilitt-førende granulitt, Vikeså, Bjerkreim, Rogaland, Norge


Sample locality used in the study of Laurent (2016). Located of the westwern side of a nameless pond between Mauratuva and the pond Store Fisketjørn. An osumilite-bearing granulite facies gneiss within the pigeonite isograd. The outcrop consists of coarse quartz–mesoperthite layers alternating with discontinuous osumilite-rich pinkish layers containing scarce relicts of garnet porphyroblasts.
