You can see some sort of foliation to it but not that distinctly (like for instance in a shale). It's subjective.
What else can I help you with?
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
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 is the texture of the gneiss rock?
Gneiss rock typically has a coarse texture due to its mineral composition of interlocking grains of quartz, feldspar, and mica. This gives it a banded or foliated appearance, with distinct layers or bands of different mineral compositions.
What grain structure does gneiss have?
Gneiss which is a non-foliated meta-igneous rock is coarse grained in texture.
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 is the texture of the rock gniess?
Gneiss is generally coarse-grained.
Does granite change into gneiss by metamorphic activity?
Yes, granite can change into gneiss through the process of metamorphism. This transformation typically involves high temperature and pressure conditions, causing the mineral composition and texture of the granite to recrystallize into the banded texture associated with gneiss.
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 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.
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.
