Mica forms flat prisms that readily brakes into flakes.
Mica.
micas such as muscovite, biotite

Biotite Mica would fit this category as would Muscovite, native to Russia as the name implied. (Sheets) oif semi-transparent mica can be peeled right off. the mineral is useful in electrical condensers and also as a form of glass substitute that is heat-resistant, called Isinglass. it is neither Eisen-(Iron) nor Glass, but the name stuck.

Clevage-a flat cut. Fracture-a cut that hes bumps in it.

A banded mineral is a mineral that has grains that are arranged in a particular pattern of flat layers or forms swirls.

Cleavage is the breaking of a mineral along flat surfaces. Fracture, on the hand is just the chipping or "fracture" of a mineral.Cleavage is the tendency to break along flat surfaces, and fracture is the tendency of a mineral to break into irregular pieces.
