Foliated rocks are formed by pressure, they are buried deep. Before, minerals are scattered in the rock randomly. After it goes through presure, minerals are squeezed together and line up in rows. This happens deep underground and inside mountains. The rock has the same minerals in it before and after pressure. The texture of these rocks are foliated. Foliated are minerals that are flattened and lined up in layers.
The foliations of metamorphic rock are created by a reorganization of the minerals in the parent rock. The foliations, layers, or bands, are formed at right angles to the direction of the pressure which is causing the foliation.
Foliation happens when a rock is compressed from one direction and partially recrystallizes. This causes crystals of minerals like mica and chlorite to grow perpendicular to the direction of the force, and gives the rock a banded appearance.
Foliation not related to layering, though if a sedimentary rock with the right mineral makeup is metamorphosed, it may take on a foliated appearance. In this case, however, the orientation of the foliation is usually at a different angle than the original layering.
The end result of foliation is that the rock is so heavily compressed that the minerals actually rearrange themselves in response to the pressure being exerted on the rock. Sometimes this even causes reactions that form new minerals. HOPE THAT HELPED! :D

This is how they are formed
Folitation is mineral layering. Usually alternating light and dark.
This is what they are.
The act or process of coating glass with metal foil.
The process of numbering consecutively the leaves of a book or manuscript
The leaves so numbered.
Geology: The layered structure common to metamorphic rocks.
High pressure during metamorphism causes minerals with flat or needle-like crystals to form with their long axes perpendicular to the pressure.

presence of platy mineral and orientation stress can give foliation to a metamorphic rocks.
No. Gneiss has foliation in the form of alternating light and dark bands.
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.
Foliation is the arrangement of minerals in parallel layers.
Metamorphic foliation is layering in metamorphic rock. The layers can be very thin, or they can be a meter thick,
Foliation occurs deep underground.

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 parallel layers.
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

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.
Metamorphic rocks often have foliation. Schist is a common example.
With a good eye you maybe could see one but usually they do not exhibit a foliation.
