Web15 de jun. de 2024 · Cleavage fracture is a fracture, usually of polycrystalline metal, in which most of the grains have failed by cleavage, resulting in bright, reflective facets. It is a type of crystalline fracture and is associated with low-energy brittle fracture. It exhibits a river pattern when examined under an electron microscope. WebAn image of an opal grain showing conchoidal fracture was imaged at low magnification (S-101). An opal grain was also imaged with backscatter electrons (BEI mode) to examine sample composition (S-102), with an accelerating voltage of 23 kV and pressure of 28 Pa. Opal shards are devoid of crystalline structure and cleavage.

Parting is usually due to lamellar twinning, as in labradorite feldspar. Parting is possible only along definite planes in twinned crystals and not along every parallel plane.
