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.
Cleavage and Fracture. Click here to go back to the main page. Cleavage is the tendency of a mineral to break along smooth planes parallel to zones of weak bonding.Fracture is the tendency of a mineral to break along curved surfaces without a definite shape. These minerals do not have planes of weakness and break irregularly.See the picture below:leavage and Fracture. Click here to go back to the main page.
