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!

∙ 13y agoThe texture of gneiss is due to heat and pressure. Rocks of different compositions can be exposed to these conditions; therefore, the composition of the gneiss will vary.

What is the texture of the rock gniess?
Gneiss is generally coarse-grained.
What is the texture of gneiss?
It is usually a gray-ish color. It is foliated (the layers are in stripes). Hope I helped!
What are the properties of gneiss?
gneiss has many properties depending on the type of gneiss it is but some common properties are fine or coarse grains, metamorphic "bands" on the rock, and it's composition which is feldspar,quartz, mica, and hornblende.
What property distinguishes foliated metamorphic rock such as gneiss and schist from nonfoliated metamorphic rocks?
A banded texture
What property distinguishes foliated metamorphic rocks such as gneiss and schist from nonfoliated metamorphic rocks?
a banded texture
What is the texture of the gneiss rock?
The texture of gneiss is coarse
What is the definition of gneiss's texture?
Coarse
What are the properties of gneiss rock?
texture: foliated
What are some facts about Gneiss?
depending on the texture
What grain structure does gneiss have?
Gneiss which is a non-foliated meta-igneous rock is coarse grained in texture.
Are Gneiss crystalline?
Yes, the gneiss rocks are usually crystalline. The gneiss rocks are foliated or banded metamorphic rocks that have the same composition as the granite.
What is the texture of the rock gniess?
Gneiss is generally coarse-grained.
The metamorphic rock texture that has alternating bands of light and dark minerals is?
gneiss

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.
Metamorphic rocks having a banded or striped appearance?
Foliated Texture
What are the properties of gneiss?
gneiss has many properties depending on the type of gneiss it is but some common properties are fine or coarse grains, metamorphic "bands" on the rock, and it's composition which is feldspar,quartz, mica, and hornblende.
