Gneiss is a metamorphic rock, not a rock group. It forms from the alteration of pre-existing rocks, such as granite or sedimentary rocks, under high temperature and pressure. Gneiss is characterized by its banded appearance, with alternating layers of light and dark minerals. It is commonly found in areas that have experienced significant geological activity, such as mountain ranges.
