How can a mineral display both cleavage and fracture? Explanation: Cleavage 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 more energetically favourable.
Can a mineral show both cleavage and fracture? All minerals exhibit a fracture, even those that exhibit cleavage. If a mineral with cleavage is chipped a certain way, it will fracture rather than cleave. There are different types of fracture a mineral can have, such as: Conchoidal – A fracture resembling a semicircular shell, with a smooth, curved surface.
How do we identify mineral by cleavage or fracture? If minerals break smoothly, along predetermined planes, the minerals are said to have cleavage. If a mineral does not have any degree of cleavage, it is said to have an irregular breakage pattern called fracture.
What causes a mineral to exhibit cleavage or fracture? 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.
