Best Answer: here are some...meaning: Cleavage in general refers to a division or separation of form. Its usage is heavily dependent on cultural context, where it may refer to: Cleavage (crystal), in mineralogy and materials science, is a process of splitting a single crystal. Cleavage (geology), Foliation perpendicular to stress as a result of ductile deformation. e.g. shales (shists) Cleavage (embryo), in embryology, is the division of cells in the early embryo. Cleavage (fiber), in optical fibers.
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.
