Cleave plane

Cleavage is a physical property traditionally used in mineral identification, both in hand specimen and microscopic examination of rock and mineral studies. As an example, the angles between the prismatic cleavage planes for the pyroxenes (88–92°) and the amphiboles (56–124°) are diagnostic. Crystal cleavage is of technical importance in the electronics industry and in the cutting of gemsto… WebJust as wood is easier to split with the grain than against it, gemstone cleavage is the tendency of certain crystals to break along definite plane surfaces. If there are planes in a crystal structure with relatively weak …

WebCleavage is the tendency of some minerals to break (cleave) along flat, parallel surfaces (cleavage planes). The cleavage planes are parallel surfaces of weak chemical bonds between repeating, parallel layers of atoms in a crystal. Each set of different cleavage planes is referred to as a cleavage direction. For example, halite, a mineral with ... WebCleavage planes are distinguished from fracture by being smooth and often having reflective surfaces. Fracture - The way a mineral breaks other than along a cleavage plane. Terminology.
