WebCleavage. The way in which a mineral breaks along smooth flat planes is called cleavage. These breaks occur along planes of weakness in the mineral's structure. However, if a mineral breaks along an irregular surface, it does not have cleavage. Fracture. When a mineral breaks irregularly, the breaks are called fractures. WebMinerals that break evenly and cleanly in one or more directions are said to have perfect cleavage. If the break is less clean, the cleavage may be described as good, distinct, or poor. Since cleavage is determined by atomic structure, some minerals will have no cleavage and some will have more than one direction.
