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 rocks. Orthogneiss is gneiss derived from igneous rock (such as granite). Para-gneiss is gneiss derived from sedimentary rock (such as sandstone). Gneiss forms at higher temperatures and pressures than schist. Gneiss nearly all the time shows a banded texture characterized by alternating darker and lighter coloured bands and without a distinct foliation.
