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 is it called when a metamorphic rock has folds or bands?
Foliation
Is sedimentary rock the only type of layered rock?
No. Extrusive igneous rocks are usually layered. Some metamorphic rocks have foliation, which resembles layering, but it is not the same thing.
Which type of metamorphosis makes non-foliated rocks?
Contact metamorphism does not often produce the foliation caused by regional metamorphism

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 salty foliation?
Slaty foliation, is a type of parallel foliation consisting of fine-grained platy minerals. The direction of foliation is usually perpendicular to the direction of maximum stress.

Foliation
How can you tell if a rock is a metamorphic rock?
A metamorphic rock will display foliation or bands around the rock.
Is sedimentary rock the only type of layered rock?
No. Extrusive igneous rocks are usually layered. Some metamorphic rocks have foliation, which resembles layering, but it is not the same thing.
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.

Contact metamorphism does not often produce the foliation caused by regional metamorphism
What is saltiness?
Slaty foliation, is a type of parallel foliation consisting of fine-grained platy minerals. The direction of foliation is usually perpendicular to the direction of maximum stress.
