Cleavage Vs. Fracture: Detailed Comparison
The Difference Between Cleavage and Fracture. Cleavage and fracture are two different ways that minerals break, and they are crucial for identifying and understanding mineral properties. Here's a detailed comparison of the two: Definition: Cleavage: The tendency of a mineral to break along flat, even surfaces that are parallel to zones of weak bonding in the crystal structure.

Is halite a fracture or cleavage?
Cleavage fracture is a fracture, usually of polycrystalline metal, in which most of the grains have failed by cleavage, resulting in bright, reflective facets. It is a type of crystalline fracture and is associated with low-energy brittle fracture.
