When granite is subjected to high enough amounts of heat and pressure to change it but not melt it granite changes to?

When granite is subjected to high heat and pressure without melting, it transforms into a metamorphic rock known as gneiss. This process involves the recrystallization of the minerals within the granite, leading to the alignment of mineral grains and the development of distinct foliation or banding. Gneiss typically exhibits a coarser texture compared to granite and may display a variety of colors depending on its mineral composition.
