Gneiss is a common and widely distributed type of Metamorphic Rock. Gneiss is formed by high-temperature and high-pressure Metamorphic processes acting on formations composed of igneous or sedimentary rock. Gneiss forms at higher temperatures and pressures thanschist. Gneiss nearly always shows a banded texture characterized by alternating darker and lighter colored bands .

Sandstone is a sedimentary rock formed through transportation, deposition, compaction and cementation of different mineral composition of sand grains.  Most sandstone is composed of Quartz or Feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface.  Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Quartz-bearing sandstone can be changed intoquartzite through metamorphism, usually related to tectonic compression .
