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.

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


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.


Difference between schistose foliation and gneiss-to foliation?

A schistose foliation would be found in a metamorphic rock with a large amount of micaceous minerals, creating a flaky texturing with easily cleavable layers. Gneiss is more coarse in texture, not as easily cleavable along planes, and contains less micaceous minerals.


Do conglomerate have foliation?

With a good eye you maybe could see one but usually they do not exhibit a foliation.


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 the arrangement of minerals in?

Foliation is the arrangement of minerals in a rock that results in a layered or banded appearance. It is commonly formed in metamorphic rocks through processes like pressure and temperature causing mineral alignment. Foliation is a key characteristic used to classify and identify different types of metamorphic rocks.


Which mineral is responsible for the strong foliation in a schist?

The mineral responsible for the strong foliation in schist is usually mica (such as biotite or muscovite). These minerals have a planar structure that aligns during the metamorphic process, creating the foliation planes in the rock.


Parallel alignment of platy grains.?

What is an example of foliation?

An example of foliation is the parallel alignment of minerals in a metamorphic rock, such as schist or gneiss. This alignment results from the pressure and temperature conditions during the rock's formation, creating a layered or banded appearance.


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 the parallel alignment of minerals that have been stressed?

The parallel alignment of minerals due to stress is called foliation. Foliation results from the deformation of minerals under pressure, causing them to align in the same direction. This alignment gives the rock a layered or banded appearance.


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.
