Non-layered Gneiss
|
gneiss (leucocratic granulite : pinkish white quartzofeldspathic gneiss; Q, perthite (Kspar) with minor accessory apatite, zircon, OPX, CPX, biotite, hornblende, oxides. Feldspars are altered to white mica and epidote resulting in the distinctive pink appearance. Originally granulite metamorphism subjected to later hydrothermal alteration) |
