What is a fracture mineral?
A fracture mineral is a type of mineral that exhibits a characteristic break along irregular surfaces rather than along smooth or flat planes. This property is known as "fracture," and it occurs when the mineral's atomic structure does not allow for cleavage, which is the tendency to break along defined planes of weakness. Common examples of fracture minerals include quartz and opal, which display a conchoidal or uneven fracture pattern. Fracture can be an important diagnostic feature in mineral identification and geology.
