- Gneiss - Wikipedia
In traditional English and North American usage, a gneiss is a coarse-grained metamorphic rock showing compositional banding (gneissic banding) but poorly developed schistosity and indistinct cleavage
- Gneiss: Metamorphic Rock - Pictures, Definition More
Gneiss usually forms by regional metamorphism at convergent plate boundaries It is a high-grade metamorphic rock in which mineral grains recrystallized under intense heat and pressure
- Gneiss | Classification, Composition, Characteristics, Formation, Uses
Gneiss is a foliated metamorphic rock that is a common distribute type of rock high-grade regional metamorphic approaches from pre-current formations that have been initially both igneous or sedimentary rocks It has a glorious banding which is apparent on microscopic scale and hand specimen
- Gneiss: Formation, Types, Composition, Uses – Geology In
Gneiss is a foliated metamorphic rock that is characterized by its banded appearance The bands are composed of different minerals, which are aligned in parallel layers Gneiss is formed by the high-temperature and high-pressure metamorphism of igneous or sedimentary rocks
- Gneiss | Metamorphic, Foliated Banded | Britannica
Gneiss, metamorphic rock that has a distinct banding, which is apparent in hand specimen or on a microscopic scale Gneiss usually is distinguished from schist by its foliation and schistosity; gneiss displays a well-developed foliation and a poorly developed schistosity and cleavage

- Gneiss: Characteristics, Formation and Identification - Sandatlas
Gneiss is a coarse-grained metamorphic rock in which most mineral grains are visible without magnification Its hallmark is gneissic banding – alternating light and dark layers produced by mineral segregation during high-temperature deformation
- Gneiss: Exploring This Rock Type and Its Characteristics
A gneiss is defined as a banded metamorphic rock generated from either a sedimentary or an igneous rock, and is composed of feldspar, quartz, mica, or hornblende, and is coarse enough that the constituent minerals can be recognized by the eye
