Cleavage Collection

Cleavage Collection
Cleavage is a readily recognizable property of some minerals and follows the internal crystal structure of that mineral. Terms used in a study of crystallography apply to the cleavage plans. 6 specimens approximately 1 1/2" x 1 1/2".

Cleavage is the tendency of minerals to break along preferred directions. Some minerals tend to have on direction of cleavage called pinacoidal cleavage. Some minerals cleave in two directions and this is referred to as prismatic cleavage. Minerals that have cleavage in three directions not at right angles have rhombohedral cleavage. If the cleavage is in three directions at right angles it is cubic cleavage. Cleavage in four directions is called octahedral cleavage.
