Micas, such as biotite and muscovite, exhibit planes of perfect cleavage due to their arrangement of atoms in parallel layers. Similarly, minerals like calcite and feldspar can form banding patterns due to variations in composition or recrystallization processes. These structured arrangements give rise to distinctive patterns in rocks like schist and gneiss.
What else can I help you with?
Is it true or false that the texture of a sedimentary rock that does not have minerals arranged in bands is described as nonfoliated?
False. The terms folidated and nonfoliated apply to metamorphic rocks.
If a metamorphic rock has grains arranged in parallel layers or bands what is the rock probably displaying?
Generically it is displaying a metamorphic fabric, specifically a schistosity. If the fabric is well developed it could also be displaying planes of cleavage.
Do sedimentary rocks have bands of minerals?
Yes, sedimentary rocks can contain bands or layers of minerals. These bands are often formed through various processes such as sediment deposition, compaction, and cementation. The minerals within these bands can vary in composition and can provide valuable information about the depositional environment and the history of the rock.
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.
What is a rock in which coarse-grained minerals separate into distinct bands?
A rock in which coarse-grained minerals separate into distinct bands is called a gneiss. Gneiss forms due to high temperature and pressure, causing the minerals to recrystallize and segregate into light and dark bands.
When mineral grains are not arranged in planes or planes bands it is called?
Non-foliated.
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 characteristic must all minerals have in order to exhibit cleavage planes?
In order to exhibit cleavage planes, all minerals must have a crystalline structure.
What is the composition of geniss?
by altering bands of minerals
What are rubber-engine aeroplanes?
they are small planes which are powered by rubber bands

What is metamorphic rocks that have parellel bands of minerals?
It is foliated
