  • Mineral Cleavage and Fracture This Old EarthIn poor cleavage, the cleavage surface is often mixed in with fractured surfaces. If a mineral exhibits no cleavage, cleavage is said to be absentin these cases the mineral is said to have fracture. Fracture can be described as either being irregular, as in the diagram at right, or conchoidal.

Advantages of mineral cleavage and fracture this old earth

cleavage and fracture city university of new yorkcleavage is the tendency of a mineral to break along smooth planes parallel to zones of weak bonding. fracture is the tendency of a mineral to break along curved surfaces without a definite shape. these minerals do not have planes of weakness and break irregularly. see the picture below: mineral cleavage test video mineral identification ( read ) earth science ck12 mineral identification elucidates the properties that allow us to identify minerals such as color, streak, luster, density, hardness, cleavage, fracture, and others. progress earth materials mineral identification historical geologycleavage and fracture minerals often show characteristic patterns of breaking along specific cleavage planes or show characteristic fracture patterns. cleavage planes are smooth, flat, parallel planes within the crystal. mineral identification earth sciencefracture is a break in a mineral that is not along a cleavage plane. fracture is not always the same in the same mineral because fracture is not determined by the structure of the mineral. minerals may have characteristic fractures (figure below). metals usually fracture into jagged edges. if a mineral splinters like wood, it may be fibrous. mineral cleavage and fracture this old earthin poor cleavage, the cleavage surface is often mixed in with fractured surfaces. if a mineral exhibits no cleavage, cleavage is said to be absentin these cases the mineral is said to have fracture. fracture can be described as either being irregular, as in the diagram at right, or conchoidal. cleavage / fracturecleavage / 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 twodimensional surfaces are known as cleavage planes and are caused by the alignment of weaker bonds glencoe earth science chapter 3 minerals vocabulary (11 here are the terms and definitions from chapter 3 on minerals from the glencoe earth science book. the terms include:mineral, crystal, magma, silicates, hardness, luster, specific gravity, streak, cleavage, fracture, and gem.
