As Mica splits perfectly parallel to its base, it is considered to have perfect basal cleavage. No other cleavage planes are present in Mica so the flaking occurs readily along this single plane. A good analogy would be a stack of A4 paper. The layers are easily peelable in one direction [parallel to the base] as opposed to the other axis [refer to the miller indices].

What is the dominant of breakage for Muscovite Mica?
Muscovite mica has perfect cleavage in one direction. It splits into thin sheets.
What does the tendency of micas to produce thin cleavage flakes suggest about its crystal structure?
the arrangement of the atoms in mica
What physical properties distinguish biotite from muscovite?
Both are platy, silicate, mica group minerals with perfect cleavage in one direction.
What is a very thin clear or silver rock?
it is mica
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.
How does the cleAvage of graphite differ from that of mica?
Cleavage refers to the tendency of a mineral to break along flat surfaces. Graphite and mica have the same type of cleavage, which is a perfect basal cleavage.
How does the mica mineral break?
Mica has perfect basal cleavage.
What is the name of a mineral that splits along flat surfaces?
cleavage
What mineral is flat with flaky cleavage?
Mica.
Is flourite a mica mineral?
No, it does not have perfect cleavage and it is not hydrous.
What is mica's clevage?
The cleavage of mica is perfect. Sometimes it has parallel parting. The cleavage laminae is flexible and elastic. The thin translucent sheets allow geologists to view the metamorphosis.
How does the cleavage of feldspar differ from the cleavage of mica?
Biotite (black mica) and muscovite (white mica) are both minerals that have perfect basal cleavage--one direction. It cleaves into thin sheets. Feldspars (albite, oligoclase, andesine, labradorite, bytownite, anorthite) have good cleavage in two directions at nearly right angles, poor in a third direction.
What is a cleavage of a mineral?
A good example of a mineral with basal cleavage are those from the mica group such as muscovite and biotite
What are two types of minerals that have cleavage?
mica and something else
Mica has one direction of what so it breaks into sheets?
Cleavage
What type of cleavage results in a thin sheet of a mineral?
Mica
Mica has one direction of so it breaks into sheets?
cleavage
