What is a nonfoliated texture?
A non-foliated rock is a metamorphic rock that does not display a lamellar texture or distinct light and dark banding common to foliated metamorphic rocks. Non-foliated rock includes quartzite, marble, and metabasalt. Non-foliated metamorphic rocks are most often derived from single mineral sedimentary rocks like limestone and quartz sandstone. == == == ==
What are metamorphic rocks with grains arranged randomly said to be?
They are called foliated metamorphic rocks, and are said to exhibit foliation.
What are rocks with grains arranged in parallel layers called?
The descriptive term is foliated.
A type of metamorphic rock in which mineral grains grow and rearrange but do not form layers?
Foliated is the general descriptive term used to describe the layering or banding of metamorphic rock.
Is iron a rock?
Yes. A rock called 'banded iron' is the main ore of iron.
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 a word for banded rock?
In sedimentary rock it is called striated or stratified. In metamorphic rock it is foliated or gneissic.
The banded appearance of many rocks is called?
layering
Does a myofibril have a banded appearance?
Yes, a myofibril has a banded appearance. The sarcomere is delimited by two dark bands which are called the Z-discs. The Z-discs have two lighter colored bands and two darker bands.
What is a metamorphic rock that starts with n?
One metamorphic rock that starts with "n" is the rock called "gneiss." Gneiss is formed from the alteration of pre-existing rocks, such as granite or sedimentary rocks, through intense heat and pressure. It is characterized by its banded or foliated appearance and can have various mineral compositions.
How do metamorphic rocks layer?
a metamorphic rock is a rock that has been changed from one rock to another by heat and/or pressure.....they amount of layers would depend on what kind of rock.....all rocks have a different amount of layers sorry
What term is used to describe metamorphic rocks with a banded texture?
The two main groups of metamorphic rocks are foliated and non-foliated. Foliated metamorphic rocks show layering and parallel alignment of flat mineral crystals (ex. micas). The "banded texture in metamorphic rocks" is one of the specific kinds of foliated textures. It is referred to as gneissic banding. Essentially, this texture displays alternating layers of light and dark minerals. These rocks are called gneiss- the light bands form from quartz and feldspars, while the dark ones form from ferromagnesian minerals.
Is Schiste foliated?
Yes. That's why it is called schist, every schist if foliated.
Is quartzite foliated?
Yes. That's why it is called schist, every schist if foliated.
What is a nonfoliated texture?

Metamorphic rocks that do not have distinct layers or bands?
non-foliated.
A metamorphic rock that has no layers is called what?
It is called Non-foliated.
