What do we call a metamorphic rock that has coarse-grained texture minimal amounts of mica and contains minerals that are segregated into bands?

A metamorphic rock with a coarse-grained texture, minimal amounts of mica, and minerals segregated into bands is called a "gneiss." Gneiss typically forms under high-grade metamorphic conditions and is characterized by its foliated structure, where the banding results from the alignment and segregation of mineral grains.
