Respuesta :

False. Gneiss is formed within high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks. It is made up of layers of sheet-like planar structures that are characterized by alternating darker and lighter colored bands, called "gneissic banding".
