WebCleavage is the property of a mineral that allows it to break smoothly along specific internal planes (called cleavage planes) when the mineral is struck sharply with a hammer. Fracture is the property of a mineral breaking in a more or less random pattern with no smooth planar surfaces. WebCleavage and Fracture The chemical bonds between atoms within a mineral are not necessarily the same strength. When the mineral breaks, it will come apart along these zones of weakness. If the zones of …

WebDefinition. If a mineral is strained beyond its elastic limits, it will break. If it breaks irregularly then it shows fracture, if it breaks along regular surfaces related to the crystal structure then it shows cleavage. This cleavage depends on weaknesses in the crystalline make-up of the mineral and is a diagnostic property which can reveal ... WebA cleavage plane is a plane of structural weakness along which a mineral is likely to split smoothly. Cleavage thus refers to the splitting of a crystal between two parallel atomic planes.

WebSpecific gravity is the ratio between the mass (weight) of a mineral and the mass (weight) of an equal volume of water. A mineral's specific gravity (SG) can be determined by dividing its weight in air by the weight of an … Weba. Cleavage is when, under stress on a specific plane, a crystal snaps. The mineral has cleavage if a portion of a crystal fractures under stress and the shattered piece still has a smooth plane or crystal structure. There is no cleavage in a mineral that, when broken off, never yields any crystallized bits.
