tatanan
anorthosite punika phaneritic, intrusive rock igneous kang ditondoi dening predominance saka plagioclase Feldspar kang meh 90-100%, lan komponèn mafic tithik.
nalika Feldspar alkali sing dijupuk saka granit, iku diganti kanggo granitoid lan mengko, dadi tonalite karo quartz minangka mineral utama.
