Gneiss is a high grade metamorphic rock, meaning that it has been subjected to higher temperatures and pressures than schist. It is formed by the metamorphosis of granite, or sedimentary rock. Gneiss displays distinct foliation, representing alternating layers composed of different minerals.

gneiss Uni Salzburg

Gneiss is a medium to coarsegrained, semischistose metamorphic rock. It is characterized by alternating light and dark bands differing in mineral composition (coarser grained than schist). The lighter bands contain mostly quartz and feldspar, the darker often contain biotite, hornblende, garnet or graphite.


Gneiss Facts Softs

Gneiss rock is further characterized by its alternating light and dark bands of minerals. Gneiss forms from volcanic rock, shale, or granitic. Quartz is typically abundantly found in gneiss. The bands that form on gneiss rock are due to the various rocks that are a part of its makeup.


Metamorphic Rock Types Pictures and Descriptions

Gneiss (quot;nicequot;) is a rock of great variety with large mineral grains arranged in wide bands. It means a type of rock texture, not a composition. This type of metamorphic was created by regional metamorphism, in which a sedimentary or igneous rock has been deeply buried and subjected to high temperatures and pressures.

Gneiss Gneiss mineral information and data.

Although a gneiss is commonly lt;mgt;feldsparlt;/mgt; and lt;mgt;quartzlt;/mgt;rich, the mineral composition is not an essential factor in its definition. Varieties are distinguished by texture (e.g., augen gneiss), characteristic minerals (e.g., hornblende gneiss), or general composition and/or origins (e.g., granite gneiss, orthogneiss, paragneiss).

Soil Genesis and Development, Lesson 1 Rocks, Minerals

Gneiss is a metamorphic rock, which forms through recrystallization of preexisting rocks under high temperature and pressure (high grade metamorphism). During metamorphosis the rock remains completely solid, and pressure is often anisotropic, which leads to preferred orientation of newly formed minerals.


Characteristics of Metamorphic Rocks ScienceStruck

These rocks have undergone partial melting due to very high temperatures, and the mineral layers are present in the form of bands or swirls of tight folds. Ptygmatic folds and Schlieren textures are common, and the protolith material in most cases is a gneiss rock. For example Gneiss migmatites, metapelitic migmatites, etc.

Gneiss can be classified on the basis of minerals that are present, presumed formational processes, chemical composition, or probable parent material. Orthogneiss is formed by the metamorphism of igneous rocks; paragneiss results from the metamorphism of sedimentary rocks.
