The chemical formula of the mineral Cavansite is indicated by Ca(VO)Si4O10(H2O)4 or Hydrated Calcium Vanadium Silicate. Cavansite is actually a Silicate mineral. Cavansite mineral was actually first discovered in the year 1967 at the Malheur County, Oregon in the United States. Cavansite mineral species derived its name from its chemical composition that is actually composed of calcium, vanadium and silicate. Cavansite is known to crystallize in the orthorhombic system. In optical mineralogy, this crystal system comprises crystals having three mutually perpendicular axes, of which all are of different lengths. The best Cavansite crystals are actually found from the quarries of zeolite minerals in Poona, India. These blue Cavansite crystals are very much amazing and splendidly exhibited in transmitted light of polarized microscopes. Cavansite mineral could be a possible ore source of vanadium. It commonly shows an interesting image as an ore mineral when viewed with the aid of an ore polarizing microscope.

 

            This mineral Cavansite is most commonly used as mineral specimens and it is usually found exhibiting nice and interesting microscope image when viewed under petrographic polarizing microscopes. Very beautiful Cavansite mineral specie is actually a considerably rare mineral. Cavansite is also considered as a very popular mineral in the mineral world because of its beauty and rarity. Cavansite crystals are usually found in deep blue color that is very attractive and exhibits a splendid view under a polarizing microscope for mineralogists. A dramatic and wonderful association of mineral Cavansite is with zeolites. These are in form of blue rosette Cavansite crystals that are perched on top of the muted colors of zeolites minerals.

 

            Cavansite minerals are commonly found in shades of greenish blue to ocean blue, which are very attractive and are commonly found fascinatingly exhibited in polarized light of petrographic polarizing light microscope. Cavansite is most commonly found exhibiting a vitreous to pearly luster in reflected light of the polarized light microscope. A perfect cleavage can be found exhibited by Cavansite in only one direction when it is evaluated between crossed nicols of polarizing light microscope for mineralogists. When Cavansite is examined under several adjustments on the aperture diaphragm of petrographic polarizing microscope, it is commonly found exhibiting a conchoidal fracture. The specific gravity measure of mineral Cavansite usually gives an approximate value of 2.33 grams per cubic centimeters. The hardness measure of mineral Cavansite when it is evaluated using the Mohs scale method is usually found ranging from 3 to 4. When mineral specimen of Cavansite is rubbed on a white streak plate, it is commonly found leaving a blue streak.

 

            Cavansite crystals are usually found transparent to translucent in appearance. The crystal habits of mineral Cavansite commonly include radiating acicular crystals that are usually forming spherical crystal clusters. Cavansite minerals can also form crystal aggregates that are generally in form of balls and are usually found splendidly exhibited under a polarizing light microscope. And these balls when evaluated with the aid of petrographic polarizing microscope can be coarse enough and almost allowing the other individual crystals to be seen. Cavansite crystals are mainly in aggregate form that commonly consists tufts or maybe spherical rosettes with pointed crystals. Cavansite crystals are also brittle. These Cavansite minerals are sometimes found as larger crystals that are commonly showing unusual internal reflection, which can be seen clearly with the aid of petrographic polarizing light microscopes.

 

            Cavansite mineral specimens are actually found as biaxial positive figures under petrographic polarizing light microscopes used in optical mineralogy. Cavansite minerals are actually not pleochroic even between crossed nicols of polarizing microscope for mineralogists. When Cavansite mineral species is evaluated between crossed nicols of petrographic polarizing light microscope, it is commonly found having a low surface relief. The birefringence found is usually found as 0.009. It also shows a weak dispersion in transmitted light of polarized microscopes. This mineral species called Cavansite is also a not radioactive mineral. There is no specific data on the toxicity and health dangers for mineral Cavansite. However, mineral specimens of Cavansite should be treated with great care and use of sensible precaution is advised upon handling them.

 

            . The best field indicators of mineral Cavansite usually include color, crystal habit, locality and its wonderful association with several interesting minerals. Cavansite minerals are commonly associated with several other interesting minerals such as heulandites, stilbite, calcite, babingtonite, quartz and apophylite. Mineral Cavansite is also considered as a secondary mineral in basalts as well as andesites. This mineral Cavansite is usually formed in pockets of volcanic basaltsCavansite minerals notably occur at some types of localities including Poona, India and the Columbia Co and Malheur Co., Oregon in the United States.
