What else can I help you with?
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.
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.
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.
What basis are metamorphic rocks classified?
Metamorphic rocks are classified primarily based on their texture and mineral composition. Texture can be either foliated, where minerals are aligned in layers or bands, or non-foliated, where mineral grains are not arranged in a specific pattern. The mineral composition reflects the original rock type and the conditions of temperature and pressure during metamorphism. Common examples include schist and gneiss for foliated rocks, and marble and quartzite for non-foliated rocks.
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.
Where can fossils only be found in?
What kind of metamorphic rock has its mineral grains arranged in planes or bands
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 would you look for to determine if a metamorphic rock is foliated?
grains arranged in solid bands.
What kind of metamorphic has its minerals grains arrange in planes or band?
Metamorphic rock with mineral grains arranaged in bands or lamellar planes are called foliated metamorphic rocks.
When mineral grains are not arranged in planes or planes bands it is called?
Non-foliated.
What kind of metamorphic rock has mineral grains arrangend in bands?
There are two answers to this question1) gneissicfor bands in such as granitic gneiss2) foliated for thin layers seen in schist.
