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.
What else can I help you with?
A metamorphic rock with visible layers or bands is said to be what?
A metamorphic rock with visible layers or bands is said to be foliated. The layers are due to the alignment of minerals or the presence of alternating light and dark bands. Examples of foliated metamorphic rocks include slate, schist, and gneiss.
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.
Is gneiss foliated or no foliated?
Gneiss is a foliated metamorphic rock, meaning it has visible layers or bands of different minerals. These layers are formed due to the intense pressure and temperature conditions that gneiss undergoes during the metamorphic process.
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 metamorphic rock that has definite layers?
A metamorphic rock with definite layers is called a foliated rock. Examples include slate, schist, and gneiss, which form due to intense pressure and heat causing minerals to align in distinct layers. Foliated rocks often have a banded appearance due to this layered structure.
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.
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.
A metamorphic rock with visible layers or bands is said to be what?
A metamorphic rock with visible layers or bands is said to be foliated. The layers are due to the alignment of minerals or the presence of alternating light and dark bands. Examples of foliated metamorphic rocks include slate, schist, and gneiss.
What is the description of foliated?
A rock with minerals aligned into bands or layers.
A metamorphic rock that has no layers is called what?
It is called Non-foliated.
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.
Is gneiss foliated or no foliated?
Gneiss is a foliated metamorphic rock, meaning it has visible layers or bands of different minerals. These layers are formed due to the intense pressure and temperature conditions that gneiss undergoes during the metamorphic process.
Is marble foliated or non foliated?
Marble is a non-foliated metamorphic rock, meaning it does not have visible layers or banding. It is formed from the recrystallization of limestone under high heat and pressure.
How can you determine if a rock is foliated or nonfoliated?
A foliated rock will have mineral grains aligned in layers or bands, giving it a striped appearance. In contrast, a nonfoliated rock will have a more uniform texture without visible layers. One way to determine if a rock is foliated or nonfoliated is by examining its texture and observing whether it exhibits a banded structure.
