Lewisian Gneiss is a type of metamorphic rock that is primarily composed of quartz, feldspar, and mica minerals. It has a banded appearance and a coarse-grained texture, and often contains evidence of deformation and metamorphism resulting from billions of years of geological activity. It is one of the oldest rocks on Earth, dating back to over 2.5 billion years ago. It is commonly found in regions with high geological activity, such as the Lewisian Gneiss Complex in Scotland.

Lewisian Gneiss has a variety of uses, including as a decorative stone, in the production of certain types of ceramics, and as a source of certain minerals such as mica.
