WebGeometric Models. Cleavage means the separation by breakage of a mineral into fragments across planes of weakness in chemical bonds. Because the orientation of ions … WebCleavage. Cleavage can be an excellent diagnostic property. It helps, for example, distinguish some amphiboles from other similar minerals. The term cleavage refers to the way a mineral cleaves, or breaks, in prefered directions. Cleavage directions represent planes of weak bonding in the mineral's atomic structure.

These flat breaks are termed “cleavage.”. The classic example of cleavage is mica, which cleaves in a single direction along the basal pinacoid, making the layers seem like pages in a book. In fact mineralogists often refer to “books of mica.”. Diamond and graphite provide examples of cleavage.
WebBut this doesn’t hold for most minerals. For example, fluorite forms cubic crystals like those of halite, but it cleaves along planes that differ in orientation from the crystal surfaces. This is illustrated in Figure 2.3.7. …
