Cleavage is the tendency of a mineral to break along flat surfaces and fracture is the tendency of a mineral to break into irregular pieces.
Cleavage is the tendency of a mineral to break along flat surfaces and fracture is the tendency of a mineral to break into irregular pieces.
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.
Quartz does not have cleavage. However, it does have fracture. Its fracture is conchoidal.
it has no cleavage
it has no cleavage
cleavage
Cleavage is when you can break the rock into square like pieces and Fracture is when you break a rock into uneven different shaped pieces.
Fracture
Hematite has a characteristic fracture, meaning it breaks irregularly with rough or jagged edges and no smooth cleavage planes.
the cleavage is Poor
Sapphire has a mixture of both cleavage and fracture characteristics. It has poor cleavage in one direction and conchoidal fracture, which means it breaks with smooth, curved surfaces similar to glass.
It has both cleavage and fracture.
