Webcleavage, tendency of a crystalline substance to split into fragments bounded by plane surfaces. Although cleavage surfaces are seldom as flat as crystal faces, the angles between them are highly characteristic and valuable in identifying a crystalline material. … WebCleavage refers to the way some minerals break along certain lines of weakness in their structure. Mica is a good example – breaking along very closely spaced flat planes that yield thin "sheets." Calcite is another good example, breaking along three different planes that yield blocky fragments that look like a rectangular box that has been warped – called a … WebSee cleavage. cleavage: The property of a mineral breaking along its crystallographic planes. ...
