    How can a mineral display both cleavage and fracture

    Nov 25, 2015Cleavage is a growth plane in the mineral, due to the structure of atoms. This means the cleavage is an easy plane to 'cleave along', meaning the mineral prefers to break along this plane. A fracture can happen in any direction, but usually a fracture will happen if it

    What Does Cleavage Mean in Earth Science? Education

    In earth science, cleavage refers to how some minerals break along flat planes when exposed to stress, such as being hit with a hammer. Cleavage creates smooth, flat surfaces that reflect light. However, not all minerals break in flat planes. Minerals that break in irregular, jagged or splintered edges are said to have fracture.

    In minerals that exhibit poor cleavage, it may be difficult to identify any cleavage surfaces. In poor cleavage, the cleavage surface is often mixed in with fractured surfaces. If a mineral exhibits no cleavage, cleavage is said to be absent; in these cases the mineral is said to have fracture.

    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.

    Cleavage and fracture. When crystals break, they can either split leaving a clean, flat face called a cleavage plane, or fracture leaving a more rough, uneven surface. We can find out more about a crystal by looking at the way it breaks. Cleavage planes form along the weakest area of mineral's structure.
