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.
Slate is certainly foliated and splits easily along this foliation surface. Gneisses frequently banded and this banding is also a foliation.
A banded texture
a banded texture
Foliated rocks have layers in them. We often refer to the layers as Banding.
foliated
Gneiss is foliated.
Gneiss is foliated and coarse grained
Yes. Gneiss is a foliated metamorphic rock.
texture: foliated
Both are foliated metamorphic rocks in which individual minerals can be seen with the naked eye. The difference is that gneiss is generally more coarsely crystalline and has color banding and schist smells bad.
Slate, gneiss, schist. Metamorphic rocks. Just the foliated ones.

Gneiss which is a non-foliated meta-igneous rock is coarse grained in texture.
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.
Yes, the gneiss rocks are usually crystalline. The gneiss rocks are foliated or banded metamorphic rocks that have the same composition as the granite.
The largest two classifications are foliated (e.g. gneiss) and non-foliated (e.g. marble).
