Mica is crystalline and forms layers.
Mica
... because calcite has a regular arrangement of atoms.
Crystals have regular, flat faces that form at very specific angles to each other and reflect their atomic structure. To identify what type of mineral you have, consult mindat.org, or a library, or a university earth science department, a local museum with mineral exhibits, or a local mineral collecting club.
Carbon. It also makes coal and diamonds. Answer: The difference in these various forms of carbon is the orientation of the carbon atoms into crystal latices. There are several allotropes of carbon: * Diamond: Trapezoidal crystals* Lonsddaleite: Diamnd with hexagonal crystals* Graphitec Flat sheets of atoms* Buckminsterfullerenes:* Carbon nanotubes* Amorphous Carbon: No crystals.
The way a mineral naturally breaks is called its cleavage. The number and orientation of cleavages can help identify a mineral. For instance, micas have a single cleavage, and break up into flat plates. Pyroxines have two cleavages at 90 degrees to each other, and break into square prisms. Calcite has three at 120 degrees, and naturally breaks into rhombs. Different minerals may have the same cleavage, but it helps to narrow down a mineral's identity.

Slate.
Cleavage is when a mineral breaks into flat pieces. Fracture is when a mineral breaks into irregular pieces. Topaz atom bonds are weaker in some parts and stronger in others. When it is equally strong then it breaks into irregular pieces and if it all weak in a flat line then it will be flat.

Mica breaks into sheets because of its unique crystal structure. Just as sand or salt is composed of granules, mica is composed of molecular sheets.
A tabular crystal habit refers to the appearance of a mineral crystal as a somewhat flat, tablet shaped form.
It wil break & produce fragments of d same shape as d parent material bcos it broke on a flat surface
That would be mica...and it's spelled "quartz"
