Answer:Gneiss is a metamorphic rock formed by changing schist, granite, or volcanic rocks through intense heat and pressure. Gneiss is foliated, which means that it has layers of lighter and darker minerals. ... Schists often have a high luster (they are very shiny) due to large crystals within the rock.
