Fracture of Minerals the nature of the surfaces formed when crystals or grains of a mineral are split. The appearance of the fracture depends on a number of mechanical properties of the mineral (including brittleness and malleability), its crystalline structure (the presence or absence of cleavage and the degree of its perfection), the nature of ...

Cleavage / fracture. Cleavage and fracture describe different ways in which a mineral can break. Definitions. Cleavage - The tendency of a mineral to break along flat planar surfaces as determined by the structure of its crystal lattice. These two-dimensional surfaces are known as cleavage planes and are caused by the alignment of weaker bonds between atoms in the crystal lattice.

In the field of mineralogy, fracture is the texture and shape of a rock's surface formed when a mineral is fractured.Minerals often have a highly distinctive fracture, making it a principal feature used in their identification. Fracture differs from cleavage in that the latter involves clean splitting along the cleavage planes of the mineral's crystal structure, as opposed to more general ...

A break or rupture in bone tissue. ♦ A comminuted fracture results in more than two fragments. ♦ Although most fractures are caused by a direct blow or sudden, twisting force, stress fractures result from repetitive physical activity. ♦ In an incomplete fracture, the fracture line does not completely traverse the bone.
