Metamorphic rocks with grains arranged randomly are said to be non-foliated. This means they do not have a layered or banded structure like foliated metamorphic rocks. Examples include marble and quartzite.
Metamorphic rock without parallel layering or flaky, schistose layers are called non-foliated metamorphic rocks.

What is the difference between foliated and non-foliated?
Foliated rocks have a layered or banded appearance due to the alignment of minerals, such as in the case of schist or gneiss. Non-foliated rocks lack this layered structure and often have a more uniform texture, like in the case of marble or quartzite.
How does a foliated metamorphic rock form?
Foliated metamorphic rocks form through directed pressure and heat acting on existing rocks, causing minerals to align in a preferred orientation. This alignment creates distinct layers or bands within the rock, giving it a foliated texture. Examples of foliated metamorphic rocks include schist, gneiss, and slate.
What do metamorphic rocks with a non-foliated texture show metamorphic changes involve?
Metamorphic rocks with a non-foliated texture show that the metamorphic changes involved did not result in the development of a preferred alignment of mineral grains. This indicates that the rocks were subjected to directed pressure or high temperatures without causing the minerals to align into layers. Examples of non-foliated rocks include marble and quartzite.
What is difference between a foliated and an unfoliated metamorphic rock.?
Foliated metamorphic rocks have a layered or banded appearance due to the alignment of mineral grains, while unfoliated metamorphic rocks do not have a layered structure. Foliated rocks form under directed pressure, while unfoliated rocks form under non-directed pressure. Examples of foliated rocks include schist and gneiss, while examples of unfoliated rocks include marble and quartzite.
What are rocks with grains arranged in parallel layers called?
Rocks with grains arranged in parallel layers are called sedimentary rocks. These rocks form when sediment such as sand, mud, or organic material is deposited and compacted over time. Examples include sandstone and shale.
When metamorphic rock has banded texture with minerals grains that are arranged in layers it is called?
The metamorphic rock with banded texture and minerals grains arranged in layers is called foliated metamorphic rock. Examples include schist and gneiss.
What do most metamorphic rocks form?
Metamorphic rocks form from the alteration of pre-existing rocks due to high temperatures, pressures, or chemically active fluids. Most metamorphic rocks form deep within the Earth's crust or upper mantle during tectonic processes such as mountain building or subduction zones.
What kind of metamorphic rock has its mineral grains arranged in planes of bands?
Metamorphic rock with mineral grains arranaged in bands or lamellar planes are called foliated metamorphic rocks.
What kind of metamorphic rock has its mineral grains arranged in bands or planes?
Metamorphic rock with mineral grains arranaged in bands or lamellar planes are called foliated metamorphic rocks.
Metamorphic rocks such as marble and quartzite are said to be what because their mineral grains are not arranged in parallel layers or bands?
Metamorphic rocks such as marble and quartzite are said to be non-foliated because their mineral grains are not arranged in parallel layers or bands like in foliated rocks such as slate or schist. This lack of alignment gives non-foliated rocks a more uniform texture and appearance.
What is the difference between foliated and non-foliated?
Foliated rocks have a layered or banded appearance due to the alignment of minerals, such as in the case of schist or gneiss. Non-foliated rocks lack this layered structure and often have a more uniform texture, like in the case of marble or quartzite.
A metamorphic rock that has grains arranged in bands is said to be?
A metamorphic rock that has grains arranged in bands is said to be foliated. Foliated metamorphic rocks show distinct layering or banding due to the alignment of minerals under heat and pressure during formation. Examples of foliated rocks include schist and gneiss.
Is it true that foliated metamorphic rocks have mineral grains that are randomly placed?
No, foliated metamorphic rocks have mineral grains that are aligned in parallel layers or bands due to the pressure and temperature conditions during their formation. This alignment gives foliated rocks their characteristic layered appearance.
Do foliated metamorphic rocks have minerals that are randomly placed?
no.
Rock with grains arranged in parallel layers?
Foliated rocks, and in particular: * Shale * Schist * Gneiss
