FRACTURE IN MINERAL IDENTIFICATION

Fracture in mineralogy is the texture and shape of the surface formed when the mineral is fractured. Fracture differs from cleavage and parting, which involve clean splitting along a plane surface, as it produces rough irregular surfaces [Ref1]. The appearance of fracture surfaces among minerals is highly varied and is a useful tool in identification.. . . Read More

USES OF CLEAVAGE, PARTING, AND FRACTURE IN MINERAL IDENTIFICATION-I

Structural failure of a mineral crystal can occur by cleavage, by parting, or by fracture.  The characteristics of any of these failure modes exhibited by a mineral can be useful as tools towards its identification. In this Blog I’ll discuss the properties of cleavage and their use in identifying minerals and follow with a second. . . Read More
