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 â¢ Breakage of a mineral along a flat plane of weakness. â¢ How To Describe Cleavage: â¢ If you see only 1 set of parallel planes... â Denoted '1 direction of cleavage' (mica was used as an example in class). â¢ If you see only 2 sets of parallel planes, you must give the int ersection angle of the two planes.
