Gneiss is a type of metamorphic rock. The minerals in gneiss may come from rocks which were originally either igneous or sedimentary. They were heated and squeezed, and the minerals recrystallized. In gneisses, minerals tend to be foliated: layered and segregated into bands.Gneiss | rock | Britannica,Gneiss is the principal rock over extensive metamorphic terrains. The banding may be oriented nearly parallel to the Earth’s surface (horizontal dip) or may have a steep dip. Such orientations can be interpreted in terms of the stresses that prevailed during the formation of the rock.Gneiss | Encyclopedia.com,08.06.2018· Gneiss (pronounced "nice") is a metamorphic rock consisting mostly of quartz and feldspar and showing distinct layering or banding. The layering of a gneiss may be weak or well-developed and consists of varying concentrations of biotite, garnet, hornblende, mica, and other minerals.
