Origin of 'gneiss'

The word 'gneiss' comes from the German language, where it originally meant 'spark'. It was first used in the field of geology to describe a type of rock with distinctive banding patterns. Gneiss is formed under high temperature and pressure conditions, usually deep within the Earth's crust. The unique banding in gneiss is a result of the segregation of different minerals during the metamorphic process. Gneiss is commonly found in mountain ranges and is often used as a decorative stone in architecture and landscaping.
