dablink This article is about the terminology used to describe fracture surfaces. For fractures in rocks and minerals per se , see Fracture geology In the field of mineralogy , fracture is a term used to describe the shape and texture of the surface formed when a mineral is broken. Minerals often have a highly distinctive fracture, making it a principal feature used in their identification. Fracture differs from Cleavage crystal cleavage in that the latter involves clean splitting along the cleavage planes of the mineral s crystal structure , as opposed to more general breakage. All minerals exhibit fracture, but when very strong cleavage is present, it can be difficult to see. Terminology Conchoidal fracture Image ObsidianOregon.jpg thumb left 180px Obsidian Conchoidal fracture is a curved breakage that resembles the concentric ripples of a mussel shell.
