WebFracture is a break in a mineral that is not along a cleavage plane. Fracture is not always the same in the same mineral because fracture is not determined by the structure of the mineral. Minerals may have characteristic fractures (Figure 9). Metals usually fracture into jagged edges. If a mineral splinters like wood, it may be fibrous. WebVerified questions.
