Gneiss is generally considered to be low in permeability due to its dense and interlocking mineral structure. However, its actual permeability can vary depending on factors such as the presence of fractures or the specific mineral composition. In some cases, weathering and structural features can create pathways that increase its permeability. Overall, while gneiss is not typically highly permeable, localized conditions may allow for some fluid movement.

Are schist rocks permeable?
Schist rocks can be both permeable and impermeable, depending on factors such as the size and arrangement of mineral grains, the presence of fractures or faults, and the level of metamorphism they have undergone. In general, schist rocks tend to have higher permeability compared to other metamorphic rocks such as gneiss or marble.
What type of crystals does gneiss rock have?
Gneiss usually consists of visible crystals of aligned mineral assemblages.
Can you use gneiss to build countertops?
Yes, you can. Gneiss is quite similar to granite.
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
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.
Are schist rocks permeable?
Schist rocks can be both permeable and impermeable, depending on factors such as the size and arrangement of mineral grains, the presence of fractures or faults, and the level of metamorphism they have undergone. In general, schist rocks tend to have higher permeability compared to other metamorphic rocks such as gneiss or marble.
What group is gneiss in?
A Gneiss is a Metamorphic rock
Is gneiss folaited or nonfolaited?
Gneiss is foliated.
What are the characteristics of gneiss?
Gneiss is foliated and coarse grained
What is gneiss mineral group?
Gneiss is a rock, not a mineral.
Is an gneiss rock sedimentary rock?
No, gneiss is metamorphic.
Where would gneiss be in the US?
Gneiss is a part of the earths lower crust. No matter where you drill you will eventually uncover gneiss.
Can gneiss metamorphose into phyllite?
No. Phyllite can metamorphose into schist and then into gneiss.
Is gneiss nonbanded?
No. Gneiss has alternating light and dark bands.
Does gneiss split with a hammer?
Yes, gneiss will split with a hammer.
Is gneiss an example of igneous rock?
No. Gneiss is a metamorphic rock.
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!
