When the metamorphic rock schist is heated and squeezed it forms what?
When schist is further heated and squeezed, it can form gneiss, another type of metamorphic rock. Gneiss is characterized by its banded texture and high-grade metamorphism.
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.
The metamorphic rock texture that has alternating bands of light and dark minerals is?
The metamorphic rock texture that has alternating bands of light and dark minerals is called foliation. This texture results from the alignment of minerals due to directional pressure during metamorphism. Schist is a common type of foliated metamorphic rock.
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.
What is a sentence for gneiss?
I am trying to find out what the other two types of rock besides gneiss form the Matterhorn. Gneiss is a metamorphic rock. That's a nice piece of gneiss!
What are the properties of gneiss rock?
texture: foliated
What is the texture of the rock gniess?
Gneiss is generally coarse-grained.
What grain structure does gneiss have?
Gneiss which is a non-foliated meta-igneous rock is coarse grained in texture.
When the metamorphic rock schist is heated and squeezed it forms what?
When schist is further heated and squeezed, it can form gneiss, another type of metamorphic rock. Gneiss is characterized by its banded texture and high-grade metamorphism.
What is the texture of gneiss?
Gneiss has a foliated texture, meaning it has visible layers or bands of different minerals. These layers are typically arranged in a repetitive pattern, giving gneiss a distinct texture that can vary in appearance depending on the type of minerals present.
What type of metamorphic rock is similar to granite?
A type of metamorphic rock similar to granite is gneiss. Gneiss is a foliated metamorphic rock that has a similar composition to granite but displays a banded texture due to the alignment of mineral grains during metamorphism.
What are the Features of gneiss rock?
The main characteristic of gneiss is gneissic texture, foliations (banding) caused by the parallel alignment of constituent minerals as a result of heat and pressure.
What property distinguishes foliated metamorphic rock such as gneiss and schist from nonfoliated metamorphic rocks?
A banded texture
Is Gneiss a sedimentary metamorphic or igneous rock?
Gneiss is a metamorphic rock that forms from the recrystallization of pre-existing rocks under high temperature and pressure conditions. It is characterized by its banded texture and coarser grain size compared to other types of metamorphic rocks.
How rare is gneiss?
Gneiss is a common type of metamorphic rock found worldwide. It forms when pre-existing rocks are subjected to intense heat and pressure, resulting in a distinctive banded texture. While gneiss is not considered rare, specific types of gneiss with unique mineral compositions or origins may be less common.
Is an gneiss rock sedimentary rock?
No, gneiss is metamorphic.
Why can the composition of gneiss vary but overall texture cannot?
The texture defines the gneiss. If it varies, it's not gneiss. I'm studying the same thing! -8th Grader! :D
