Cleavage is the tendency of a material to split apart along flat,smooth planes. These are planes of weak atomic bonding within the material. Cleavage is described as perfect,good,fair,poor,distinct or indistinct. Splitting along irregular flat planes is sometimes called 'parting',but this may not be apparent in all specimens of a given mineral. Many minerals have perfect cleavage,and in some cases in more than one direction. Cleaved surfaces can be extremely flat and smooth,such as in the case of the topaz in the photo | |
