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.
Also as a fibrous mass (asbestos) and as a fibrous and very compact mass (nephrite jade). Cleavage: is perfect in two directions at close to 60- and 120-degree angles. Fracture is splintery to uneven. Specific Gravity is approximately 2.9 - 3.3 (very slightly above average for translucent minerals).
