micas such as muscovite, biotite
Mica forms flat prisms that readily brakes into flakes.
The mineral that is flat with flaky cleavage is mica. Mica is a group of silicate minerals that can easily be split into thin sheets or flakes. These sheets have excellent cleavage, making them easily separable into thin layers.
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.
cleavage
Cleavage is a mineral's ability to split easily along flat surfaces due to the arrangement of its atoms in crystal structure.

Cleavage.
A banded mineral is a mineral that has grains that are arranged in a particular pattern of flat layers or forms swirls.
cleavage
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.
cleavage
to have flaky skin
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.
