Definitions. Cleavage-The tendency of a mineral to break along flat planar surfaces as determined by the structure of its crystal lattice. These two-dimensional surfaces are known as cleavage planes and are caused by the alignment of weaker bonds between atoms in the crystal lattice.leavage and fracture describe different ways in which a mineral can break. Cleavage-The tendency of a mineral to break along flat planar surfaces as determined by the structure of its crystal lattice.
What is the difference between fracture and cleavage? Cleavage and fracture differ in that cleavage is the break of a crystal face where a new face (resulting in a smooth plane) is formed, whereas fracture is the chipping shape of a mineral. All minerals exhibit a fracture. If a mineral with cleavage is chipped a certain way, it will fracture rather than cleave.
