Gneiss typically has low porosity, usually ranging from about 1% to 5%. This is due to its metamorphic nature, characterized by tightly interlocking mineral grains that result from high pressure and temperature conditions. The low porosity means that gneiss generally has limited capacity to hold water or other fluids compared to more porous rocks like sandstone or limestone.
What else can I help you with?
What is the density of gneiss?
Gabbro has a very rough texture (referred to as coarse or phaneritic) .
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.
What is the density of gneiss?
Gabbro has a very rough texture (referred to as coarse or phaneritic) .
What is low porosity and high porosity?
big particles=low porosity small particles=high porosity
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.
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.
Is gneiss nonbanded?
No. Gneiss has alternating light and dark bands.
