Step 1

Cleavage refers to the way a mineral breaks along specific planes, which is related to its crystal structure. a. If the sample does not show any smooth, flat surfaces when it breaks, it has no cleavage and fractures instead. b. If the sample breaks along one Show more…

Key Concepts

Cleavage

Cleavage is the tendency of a mineral to split along specific, well-defined planes of weakness dictated by its atomic structure. This characteristic is used to help identify minerals and understand their crystallographic properties.

Fracture

Fracture describes the pattern in which a mineral breaks when it does not cleave along its natural planes. Instead of smooth surfaces, the break creates irregular or curved surfaces, which reveals information about the mineral's internal bonding and structure.

Cleavage Planes

Cleavage planes are the distinct flat surfaces along which minerals tend to break due to weaknesses in their crystal lattice. The number and angular relationship of these planes, such as those not at 90-degree angles, are critical diagnostic features used in mineral identification.
