Thekey differencebetween cleavage and fracture is thatcleavage is the manner in which amineral沿其无力的平面破裂，而骨折是当原子粘结是完美的，没有弱点时矿物的破裂。
Cleavage and fracture are physical characteristics that help in the identification of a mineral. The words cleavage and fracture are very common words that we use in many contexts. However, it is while identifying minerals that these words are used together as these are physical attributes of minerals and help in mineral identification as different minerals have different types of fractures and cleavages. Accordingly, like colour, density, lustre, etc., fracture and cleavage too become a basis of differentiation between different minerals.
What is Cleavage?
Cleavage is the manner in which a mineral break along its plane of weakness. It occurs along the smooth planes that are parallel to zones of weak bonding. Furthermore, it can occur in different ways as follows:
- Cleavage in one direction. i.e. muscovite
- In two directions. i.e. feldspar
- In three directions – cubic. i.e. halite, and
- Cleavage in three directions – rhombohedral. i.e. calcite.
Traditionally, we use this property for identification of different minerals. It is useful in both hand specimen identification and microscopic examination of minerals.
Moreover, it is important in cutting gemstones. Also, it is important in the electronics industry. For instance, Synthetic single crystals of semiconductor materials are generally sold as thin wafers which are much easier to cleave.
What is Fracture?
Fracture is s breakage of a mineral when atomic bonding is perfect, and there is no weakness. It occurs along curved surfaces without a definite shape. The minerals that have this property has no panes of weakness. Moreover, they break irregularly.
What is the Difference Between Cleavage and Fracture?
Cleavage and fracture are two properties of minerals. The key difference between cleavage and fracture is that the cleavage is the manner in which a mineral break along its plane of weakness whereas fracture is breakage of a mineral when atomic bonding is perfect, and there is no weakness.
As another important difference between cleavage and fracture, we can say that cleavage is regular, but fracture is irregular. As examples of minerals with cleavage we can give halite, calcite, gypsum, etc. Quartz is a mineral that shows fracture rather than cleavage.
概括– Cleavage vs Fracture
Cleavage and fracture are physical characteristics that help in the identification of a mineral. The key difference between cleavage and fracture is that the cleavage is the manner in which a mineral breaks along its plane of weakness whereas fracture is a breakage of mineral when atomic bonding is perfect, and there is no weakness.
