WebMay 15, 2024 · Fracture is breakage, which occurs in directions that are not cleavage directions. Some minerals, such as quartz, have no cleavage whatsoever. When a mineral with no cleavage is broken apart by a hammer, it fractures in all directions. Quartz is said to exhibit conchoidal fracture. WebTopaz. 1. Parting (pseudo cleavage) – Some crystals can be divided in two, along a plane of weakness known as a parting plane which is along a twin plane. 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.
