Question

Quizplus · Accepted Answer

Granite gneiss is characterized by the segregation of light- and dark-colored minerals into thin layers or bands, a feature known as gneissic banding. This occurs during high-grade metamorphism where the rock is partially melted and recrystallized under differential stress, causing the minerals to segregate based on their chemical and physical properties.
