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.
What type of rock often have foliation?
Metamorphic rocks often have foliation. Schist is a common example.
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.
Are slate and gneiss foliated?
Slate is certainly foliated and splits easily along this foliation surface. Gneisses frequently banded and this banding is also a foliation.
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.
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.
Foliated rocks are distinguished by?
The main way metamorphic rocks are classified is by the presence or absence of foliation. Foliated metamorphic rocks are distinguished by the type of foliation they exhibit. Types of foliation textures, include: slaty, phyllitic, schistose, and gneissi.
What type of foliation is the product of at least two deformations?
Crenulation cleavage.
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 is the arrangement of minerals in?
Foliation is the arrangement of minerals in parallel layers.
How is the orientation of foliation related to stress?
The foliation in metamorphic minerals is always perpendicular to the direction of pressure. E.g. Vertical pressure is applied, the foliation will be horizontal, and vice-versa, the pressure is horizontal you get vertical foliation. From yahoo answers

Do conglomerate have foliation?
With a good eye you maybe could see one but usually they do not exhibit a foliation.
What is metamorphic foliation?
Metamorphic foliation is layering in metamorphic rock. The layers can be very thin, or they can be a meter thick,
