Gabbro has a very rough texture (referred to as coarse or phaneritic) .
Gneiss typically contains crystals of quartz, feldspar, and mica. These crystals are aligned in layers or bands, giving gneiss its characteristic banded appearance.
Yes, you can. Gneiss is quite similar to granite.
The texture defines the gneiss. If it varies, it's not gneiss. I'm studying the same thing! -8th Grader! :D
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.

big particles=low porosity small particles=high porosity
Gneiss is foliated.
A Gneiss is a Metamorphic rock
Gneiss is a rock, not a mineral.
Gneiss is foliated and coarse grained
No, gneiss is metamorphic.
Gneiss is a part of the earths lower crust. No matter where you drill you will eventually uncover gneiss.
No. Gneiss is a metamorphic rock.
No. Phyllite can metamorphose into schist and then into gneiss.
No. Gneiss has alternating light and dark bands.
Yes, gneiss will split with a hammer.
