Cleavage / fracture

Cleavage / fracture Cleavage and fracture describe different ways in which a mineral can break 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...

Cleavage crystal

Cleavage, in mineralogy, is the tendency of crystalline materials to split along definite crystallographic structural plan 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 ,...

26 Mineral Properties Physical Geology

Cleavage is what we see when a mineral breaks along a specific plane or planes, while fracture is an irregular break Some minerals tend to cleave along planes at various fixed orientations, some do not cleave at all they only fracture Minerals that have cleavage can also fracture along surfaces that are not parallel to their cleavage plan...

Garnet The mineral Garnet information and pictures

Garnet is not a single mineral, but a group contains closely related, isomorphous minerals that form a series with each other The Garnet members form intermediary minerals between each member, and may even intergrow within a single crystal The Garnets vary only slightly in physical properties, and some of the members may be so similar that they are indistinguishable from one another without ....

Gemstone Cleavage at AJS Gems

The difference between a cleavage and a fracture is that a fracture is arbitrary and non-repeatable -- it can occur anywhere on the body of a mineral, in any spatial direction, with little chance of an identical fracture occurring A cleavage, on the hand, is predictable and repeatable A mineral can have one or more cleavage plan...
