Foliation is caused by heat and pressure being applied to the parent rock. The heat and pressure combine to realign the existing minerals from a random orientation to one of parallel orientation, thus creating the visible lines or platy cleavages found in foliated metamorphic rocks. The lines of foliation are created perpendicularly to the force being applied.

What kind of rocks are rocks in which the structure texture or composition have changed?
Metamophic Rock :)
Which kind of rocks are in which the structure texture or composition have been changed?
Metamophic Rock :)
Are sedimentary rocks classified tofoliated sedimentary rocks?
No, sedimentary rocks are not classified as foliated. Foliation is a textural feature found in certain types of metamorphic rocks where minerals are aligned in layers or bands due to pressure and heat. Sedimentary rocks are formed by the accumulation and cementation of sediments and do not exhibit foliation.
What type of rock often have foliation?
Metamorphic rocks often have foliation, which is a layered structure that results from the alignment of mineral grains due to heat and pressure during formation. Common types of foliated rocks include slate, schist, and gneiss.
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.

Foliation is caused by?
Foliation in rocks refers to the process being split into thin sheets. It is caused by intense pressure that shapes rocks to align in particular directions.
Are sedimentary rocks classified tofoliated sedimentary rocks?
No, sedimentary rocks are not classified as foliated. Foliation is a textural feature found in certain types of metamorphic rocks where minerals are aligned in layers or bands due to pressure and heat. Sedimentary rocks are formed by the accumulation and cementation of sediments and do not exhibit foliation.
What is nonfoliated texture?
Metamorphic rocks that do not exhibit foliation.
What major group does foliated rocks belong?
Foliation is a characteristic of some metamorphic rocks.
Why don't all rocks have foliation?
Not all rocks exhibit foliation because foliation is primarily a characteristic of metamorphic rocks that have been subjected to directed pressure and temperature, causing minerals to realign into parallel layers. Igneous rocks, which form from the cooling of molten material, and sedimentary rocks, which are formed from the accumulation and lithification of sediments, generally lack this layered structure. Additionally, the specific mineral composition and the conditions of formation play a crucial role in whether foliation develops. Consequently, only certain metamorphic environments and rock types will display foliation.
What type of rock often have foliation?
Metamorphic rocks often have foliation, which is a layered structure that results from the alignment of mineral grains due to heat and pressure during formation. Common types of foliated rocks include slate, schist, and gneiss.
How do foliated rocks break?
Usually along the plane of foliation.
