Mica is not a type of foliated rock but is in fact the name for a subdivision of a group of minerals known as Phyllosilicates.
They form as parallel sheets of silicate tetrahedra resulting in thin sheet like crystals. Foliations are planer alignments of crystals within metamorphic and igneous rocks and foliated rocks may contain micaceous minerals.
See the related link for a picture of a Quartz-Mica Schist seen in thin section and viewed through a petrographic microscope with the polarising filters crossed.
In the example picture the white, grey and black amorphous blobs are quartz crystals and the long, thin, brightly coloured (predominantly blue and yellow) crystals are muscovite mica.

What is mica schist?
Mica schist is a metamorphic rock that contains abundant mica minerals, which give it a shiny, reflective appearance. It forms from the metamorphism of shale or other sedimentary rocks rich in clay minerals. Mica schist is often used in construction and landscaping due to its attractive appearance and durability.
Is mica fluorescent?
No, mica is a metamorphic rock. It is an excellent high voltage insulator.
Is schist the same as mica schist?
No, schist is a metamorphic rock type characterized by strong foliation, while mica schist is a specific type of schist that contains a high proportion of mica minerals like muscovite or biotite. Mica schist has a distinct shiny appearance due to the abundance of mica minerals.
Is mica schist rock worth money?
one puond is probably $15 maybe?
What igneous rock is made up of mica feldspar and quartz?
The igneous rock most likely described is granite, which is composed predominantly of mica (specifically muscovite or biotite), feldspar, and quartz. This rock type forms from the cooling and crystallization of molten magma deep within the Earth's crust.
How old is mica the rock?
Mica minerals typically form in rocks millions to billions of years old. The specific age of a rock containing mica would depend on the geologic history of the area where it was formed.
Which would not be consider as a mineral water diamond mica or quartz?
Quartz
Is Mica a solid liquid or gas?
Mica is a solid
What is a mica rock?
no it is a mineral
Does the rock mica have a chemical composition?
Mica is a class of minerlas, not a rock. Different micas have different chemical compositions.
What rock is formed when mica is metamorphosed?
Mica is formed by chemicals combining their industrial forces with fresh water and turning into thin breakable sheet rock.
What type of rock is mica schist?
It is a folliated metamorphic rock.
What rock has all mica?
gem stone
How is garnet mica formed?
A Mica Garnet schist is a metamorphic rock formed from a shale or a granitic mother rock when this is squashed and heated at death in the crust.
What is the word obtained after unscrambling the word mica?
The spelling mica is a word, a soft rock. There are no common anagrams.
What is the intrusive pink rock with mica?
The intrusive pink rock with mica is likely to be granite. Granite is an igneous rock that forms from the slow cooling of magma deep underground. The pink color is often due to the presence of potassium feldspar, and mica minerals, such as biotite or muscovite, can be found in granite as well.
What is a very thin clear or silver rock?
it is mica
