The foliation is caused by the massive force of pressure and high temperature which results from mountain building processes caused by plate collisions. 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.

∙ 6y agoMost metamorphic rocks have a sort of platy or planar structure which is caused by the parallel alignment of micas or other flat minerals. This structure is called foliation.

A metamorphic rock with visible layers or bands is said to be what?
Visible layers or bands in metamorphic rock is designated as 'foliation' and the rock is said to be 'foliated'.
Metamorphic rock that show layers of dark minerals alternatin with layers of light minerals are classified as?
Foliated is the correct answer!!!
What is a foliated structure?
In geology, a foliated structure refers to a rock or mineral that is composed of thin easily separable layers. Examples of foliated rocks are gneiss, phyllite, schist and slate.
When metamorphic rock has banded texture with minerals grains that are arranged in layers it is called?
Metamorphic rocks with a layered or banded look are referred to as foliated.
What is the texture of gneiss?
It is usually a gray-ish color. It is foliated (the layers are in stripes). Hope I helped!
What type of rock has light and dark layers?
foliated.
What is a type of metamorphic rock that has parallel layers?
Foliated rock has parallel layers.
A metamorphic rock that has visible layers or bands?
foliated rock
What metamorphic rock type has flat layers?
Foliated rock
What Metamorphic rock that don't have layers?
non-foliated.
How are slate and marble different?
Slate is a foliated (displaying layers or banding) metamorphic rock, and its parent rock was shale or mudstone. Marble is a non-foliated metamorphic rock (no layers or bands) and its parent rock was limestone.
If a rock has bands of light and dark layers it is?
It could be foliated metamorphic rock or sedimentary rock, depending on its mineral makeup and method of formation.
A metamorphic rock that has no layers is called what?
It is called Non-foliated.
What is the description of foliated?
A rock with minerals aligned into bands or layers.
How does a foliated metamorphic rock form?
Metamorphic rocks have their grains arranged in parallel layers or bands that are said to be foliated.
A metamorphic rock with visible layers or bands is said to be what?
Visible layers or bands in metamorphic rock is designated as 'foliation' and the rock is said to be 'foliated'.
What is difference between a foliated and an unfoliated metamorphic rock.?
foliated rocks are arranged in parallel layers, or bands. Unfoliated rocks are not banded and are not put into parallel layers.
