WebSep 18, 2024 · Cleavage is the tendency of a mineral to cleave or break along flat planes of weak bonding. Cleavage results in formation of sheets of material. Let's look at the micas, for example. WebCleavages are described in terms of their quality - how smoothly the mineral breaks - and their difficulty - how easy, or how hard, it is to produce the cleavage. The quality of cleavages are perfect, imperfect, distinct, good, fair, and poor . The difficulty is described as easy , hard, and difficult to produce.

WebBoth these properties represent the reaction of a mineral to an external force. Cleavage is breakage along planar surfaces, which are parallel to possible external faces on the crystal. It results from the tendency of … Cleavage, in mineralogy and materials science, is the tendency of crystalline materials to split along definite crystallographic structural planes. These planes of relative weakness are a result of the regular locations of atoms and ions in the crystal, which create smooth repeating surfaces that are visible both in the microscope and to the naked eye.
