Rock foliation is the result of pressure and recrystallization when rocks undergo metamorphosis. It is the layering and parallel alignment of flattened or directionally oriented mineral crystals. Slate, phyllite, schist, and gneiss are all metamorphic rocks with foliated texture.

What is an example of foliation?
Foliation is the layering of metamorphic rock. An example of foliation would be a rock called a Gneiss. On this rock, it is easily apparent to see the layers of rock that have formed.
Do all metamorphic rocks have layers?
No. The layering or foliation only occurs when there is a variation in the composition of the original rock. If the rock is homogeneous, then there will be no foliation.
What type of rock often have foliation?
Metamorphic rocks often have foliation. Schist is a common example.
What is it called when a metamorphic rock has folds or bands?
Foliation
What common structure is found in a metamorphic rock?
fold
How can you tell if a rock is a metamorphic rock?
A metamorphic rock will display foliation or bands around the rock.

How can you tell one metamorphic rock to another metamorphic rock?
Well it is pretty easy here it goes: A metamorphic rock will display foliation or bands around the rock.
Do all metamorphic rocks have layers?
No. The layering or foliation only occurs when there is a variation in the composition of the original rock. If the rock is homogeneous, then there will be no foliation.
What type of rock often have foliation?
Metamorphic rocks often have foliation. Schist is a common example.
What is metamorphic foliation?
Metamorphic foliation is layering in metamorphic rock. The layers can be very thin, or they can be a meter thick,
What causes foliation on a metamorphic rock under what cirumstances would you expect this to happen?
Foliation is created when pressure pushes different parts of the rock in different directions.
What is it called when a metamorphic rock has folds or bands?
Foliation
Why doesn't quartzite exhibit foliation?
To exhibit a foliation one needs the presence of at least two mineral types to form the foliation layering. As quartzite is a single mineral rock, it will remain massive even in environments where the adjacent rock types have become foliated.
Is shale foiliated?
No. Shale is laminated. It is a sedimentary rock. Foliation is a characteristic of metamorphic rock.
What two things are necessary for foliation to form in a metamorphic rock?
presence of platy mineral and orientation stress can give foliation to a metamorphic rocks.
Does metamorphic rock have layers?
Not exactly. Some metamorphic rocks have foliation, which can appear similar to the layers of sedimentary rock. Foliation develops from mineral grains being oriented by pressure, rather than the deposition of layers.
