Gneiss is formed from pre-existing rocks that are subjected to intense directional pressure and heat, causing an alignment of their constituent minerals into parallel bands, a texture that is referred to as foliation.

How does gneiss differ from the rock it was formed?

They are both metamorphic rocks. One difference is the rocks they are formed from. Gneiss is formed from Feldspar and Quartz. Gneiss can also contain muscovite, biotite and hornblende. Quartzite is formed from sandstone. Also Gneiss is more intensely foliated than Quartzite. This can be seen in the bands formed in Gneiss, while quartzite has no bands. Pure quartzite is white, while Gneiss is grey or pink, with dark streaks.


Gneiss is formed from what rock?

Gneiss is a metamorphic rock. It is formed form another metamorphic rock called schist (sh-ist). Schist is formed form fine grained sedimentary rock (often shale). While gneiss is formed by great pressure from moving plates of the earth's crust.


Is gneiss an organic rock?

No, gneiss is not an organic rock. It is a metamorphic rock formed from the recrystallization of pre-existing rocks like granite or sedimentary rocks under high temperatures and pressures. Organic rocks are formed from the remains of living organisms, like limestone or coal.


Another name for the metamorphic rock called nice?

The rock called "nice" is a type of metamorphic rock known as gneiss. Gneiss is characterized by its banded appearance, formed by the recrystallization of minerals under high temperature and pressure conditions.


How are granite and gneiss the same?

Granite and gneiss are both types of rocks that are formed from the cooling and solidification of molten magma or rock. Gneiss is actually a metamorphic rock that is derived from granite through the process of metamorphism. Both rocks exhibit visible mineral grains and are commonly used in construction and landscaping due to their durability.
