3.5.2: Cleavage, Fracture, and Parting - Geosciences LibreTexts
Fluorite is the most common example of a mineral that has four perfect cleavages; the cleavage directions are parallel to the octahedral faces. Many fluorite cleavage fragments are perfect …
Fluorite | Common Minerals
Calcite and fluorite can be distinguished by differences in cleavage. Fluorite cleaves in four directions to form octahedrons, while calcite cleaves in three directions to form rhombohedra. …
Fluorite - Wikipedia
Fluorite has four perfect cleavage planes that help produce octahedral fragments. [14] The structural motif adopted by fluorite is so common that the motif is called the fluorite structure. …
Fluorite of Utah and Beyond - Natural History Museum of Utah
Fluorite has perfect octahedral cleavage in multiple directions. Cleavage planes often show up in crystals as thin fracture or crack lines. Image 13 illustrates these cleavage lines in a cluster of …
The Mineral fluorite - The Mineral and Gemstone Kingdom
Fluorite has interesting cleavage habits. The perfect cleavage parallel to the octahedral faces can sometimes be peeled off to smooth out a crystal into a perfect octahedron. Many crystals, …
