Description

A coarse-grain metamorphic rock with an irregular layered structure of varying mineral compositions and colors. Gneiss is similar in composition to granite but different in texture. In general, some bands are high in feldspar or quartz while others are higher in hornblende or mica. Gneiss stones are used in building construction and are often sold as granites.
