Web10.2 Foliation and Rock Cleavage How Foliation Develops. When a rock is acted upon by pressure that is not the same in all directions, or by shear stress (forces acting to “smear” the rock), minerals can become elongated in the direction perpendicular to the main stress. The pattern of aligned crystals that results is called foliation. WebCleavage refers to flat planes along which some minerals break. Fracture can be described as conchoidal, rough, smooth, or fibrous. Minerals can be identified by how they break. Obsidian (left), although not a mineral because of its lack of crystal structure, shows excellent conchoidal fracture. Asbestos (right), which is the common name for ...
