Fracture
Cleavage
Cleavage
This property is called cleavage.
Cleavage is the splitting of rocks or minerals along defined surfaces.
The tendency for minerals like mica to break along flat surfaces is called cleavage. Cleavage occurs because the atomic structure of these minerals allows them to easily break along specific planes, resulting in flat, shiny surfaces.
cleavage
This is known as conchoidal fracture.
Cleavage. Minerals with cleavage have a tendency to break along planes of weakness determined by their crystal structure, resulting in smooth, flat surfaces. Cleavage is a key diagnostic property used to identify minerals.
cleavege of the mineral
Many minerals have "cleavage" that causes them to split on flat cleavage planes. Such minerals include micas (muscovite, biotite. phlogopite), calcite, gypsum, and feldspars. Cleavage is the result of the minerals' crystal structure that has weaker chemical bonds aligned in planes.

They are said to exhibit fracture instead of cleavage.
