A crystal structure is the repetitive patterns in a mineral form. Cleavage is the ability of a mineral to break into flat surfaces. A fracture is a term used for an irregular way a mineral breaks apart.
Study of the mineral and the crystal structure.
- The underlying internal architecture of a crystalline substance, or its crystal structure, is expressed in a mineral's outward morphology. The three-dimensional regular (or ordered) arrangement of chemical units (atoms, ions, and anionic groups in inorganic materials; molecules in organic substances) that make up a crystal structure is reproduced in different ways via translational and symmetry operations and are referred to as motifs.
- The term "cleavage" describes the way some minerals fracture along specific structural lines of weakness. Mica is a wonderful example since it breaks along flat planes that are very closely spaced apart and produces thin "sheets."
- A mineral can fracture when it splits in an irregular pattern without any smooth, plane surfaces.
