What is mineral cleavage?
cleavage, tendency of a crystalline substance to split into fragments bounded by plane surfaces. Although cleavage surfaces are seldom as flat as crystal faces, the angles between them are highly characteristic and valuable in identifying a crystalline material. Related Topics: mineral.

What is the difference between mica and muscovite?
is that muscovite is (mineralogy) a pale brown mineral of the mica group, being a basic potassium aluminosilicate with the chemical formula k]]al2(si3al)o10(oh,[[fluorine|f)2; used as an electrical insulator etc while mica is any of a group of hydrous aluminosilicate minerals characterized by highly perfect cleavage.

Does mica have cleavage or fracture?
Mica, for example, has only one really good cleavage plane, it splits easily into very thin layers. Another example, calcite, will split along three cleavage planes giving a ‘diamond’ shape called a rhombohedron.
What minerals are found with mica?
The principal mica minerals used in commercial applications are biotite, muscovite and phlogopite. Biotite is generally used in its ground (particulate) form as a soil additive; muscovite and phlogopite have applications in sheet and ground forms.
What is quartz cleavage?
Quartz has no cleavage.
