Opal does not have a cleavage or fracture because it lacks a distinct cleavage plane like minerals such as mica or calcite. Instead, opal typically fractures conchoidally, meaning it breaks with smooth, curved surfaces similar to glass.

Is Zinc a cleavage or an fracture?

Zinc is a metal that exhibits a fracture rather than cleavage. Fracture refers to the way a mineral breaks when it is not along cleavage planes, while cleavage refers to the tendency of a mineral to break along flat planes.


What are 3 differences between cleavage and fracture?

Cleavage is the tendency of a mineral to break along planes of weak atomic bonding, resulting in smooth, flat surfaces, while fracture is the tendency of a mineral to break with rough, irregular surfaces. Cleavage results in smooth, reflective surfaces that reflect light, whereas fracture surfaces are dull and do not reflect light. Cleavage is a property that is characteristic of certain minerals and can be used for mineral identification, while fracture can vary depending on the specific conditions of the break and is less consistent across different minerals.


Is gold a fracture or a cleavage?

Gold exhibits a fracture rather than cleavage. Fracture describes how a material breaks when no preferential planes are present, in contrast to cleavage which denotes how a material breaks along specific planes determined by its crystal structure. Gold's fracture is typically uneven and jagged.


What s the difference between a mineral that has cleavage and one that has fracture?

The difference between a mineral that has cleavage and one that has fracture is that cleavage is the tendency of some minerals to brake along flat surfaces and fracture is the tendency of some minerals to brake unevenly along curved or irregular surfaces.
