Fluorite: The mineral fluorite information and pictures

Fluorite is the only mineral for which significant quantities of the important element fluorine can be obtained. Fluorite is also used as a flux in the manufacture of steel and other metals to eliminate impurities.There is a great demand for Fluorite in the optics field, and to meet it synthetic crystals are grown to produce special lenses.

What is the cleavage for fluorite Answers

Fluorite, as mention above, has octahedral cleavage. This means that it has four identical directions of cleavage and when cleaved in the right ways can produce a perfect octahedral shape.

Fluorite: Mineral information, data and localities.

Fluorite Group. Fluorite is found as a common gangue mineral in hydrothermal veins, especially those containing lead and zinc minerals. It is also found in some greisens, granites, pegmatites and high-temperature veins, and as a component of some marbles and other metamorphic rocks.

University of Minnesota’s Mineral Pages: Fluorite

Although fluorite crystals occur in a range of colors, dark purple fluorite crystals are probably the best-known fluorite variety as they are often prominently displayed in museum galleries and mineral book photos. These dark purple or violet crystals are easily confused with amethyst (purple quartz), although fluorite’s distinctive crystal shape, four planes of cleavage, and its relative

Fluorite GEO143 Mineral Webpages Google Sites

Cleavage/Fracture: Fluorite is a unique mineral when it comes to its cleavage due to its four directions of perfect cleavage, something not seen many common minerals. The shape of fluorite often resembles an octahedron. (3) Crystal Form: Fluorite crystals are equal in dimension because they have an isometric crystal habit. Fluorite typically takes on a cubic form, although other complex forms

Donald B Peck Determining Fracture and Cleavage in

Four cleavage planes produce an octahedral cleavage block and so four directions of cleavage are known as octahedral cleavage. Fluorite and diamonds both have octahedral cleavage. Enlarge the thumbnail photo at the right (click on it) and note that the incipient cleavage faces in the block are parallel to the external cleavage faces. The symmetry of the isometric system requires that if there

Cleavage of Minerals Geology In

Fluorite, calcite, and barite are minerals whose cleavage is perfect. 'Distinct' cleavage implies that cleavage surfaces are present although they may be marred by fractures or imperfections. 'Difficult' or 'indistinct' cleavage produces surfaces which are neither smooth nor regular; samples possessing such cleavage tend to fracture rather than split.

YupRocks Pictures of the Mineral Fluorite

The mineral Fluorite occurs in nature as a vein deposit, mainly with metallic minerals, wherein it habitually forms a component of the gangue (the neighboring "host-rock" in which precious minerals occur) and could be coupled with Galena, Barite, Quartz, Sphalerite and Calcite. This mineral is often found in deposits of hydrothermal origin and has been renowned as a primary mineral in granites

How Can I Tell the Difference Between Fluorite & Quartz

Quartz and fluorite are two very different minerals, each with a different hardness and crystal structure, although on the surface they look very similar. Both rocks come in clear or white tones, as well as purple, pink, blue and green. The visual similarities make them difficult to tell apart, but you can distinguish the two minerals with some simple tests. Determining the Difference Between
