The chemical formula of mineral Cuprosklodowskite is indicated by Cu(UO2)2Si2O7 – 6H2O or Hydrated Copper Uranyl Silicate. Cuprosklodowskite is actually a Silicate mineral. The name Cuprosklodowskite was actually supplied by Buttgenbach while introducing Vaes paper, in the mistaken belief that it was the copper analog of sklodowskite. The name actually originated from the word copper and sklodowskite. Cuprosklodowskite mineral was first discovered in the year 1933 at Shaba, Zaire. Cuprosklodowskite is known to crystallize in the triclinic system of crystal formation. In optical mineralogy, this triclinic crystal system commonly comprises crystals having three axes, of which all are unequal in length and are positioned oblique to one another. Mineral Cuprosklodowskite is commonly used as a mineral specimen and it commonly exhibits interesting microscope images when viewed with the aid of petrographic polarizing microscopes used in optical mineralogy. Cuprosklodowskite is also considered as a very minor ore of uranium. As an ore mineral, Cuprosklodowskite is usually found exhibiting a splendid microscope image under an ore polarizing light microscope.

 

Cuprosklodowskite is a rare uranium mineral that was formed from the oxidation of copper and uranium bearing minerals. Good crystals of mineral Cuprosklodowskite are only found in one mine called Musonoi Mine, the famous uranium and copper mine in the world found in Shaba, Zaire. This mine produces the finest Cuprosklodowskite mineral crystals, which are used to supply the worlds need. Mineral Sklodowskite and Uranophane are closely related minerals. They both have similar chemistry, crystal habit and structure. Mineral Cuprosklodowskite is commonly exhibiting bright green velvety tufts that are found as hair like crystal formations, which are usually very attractive and interesting when viewed under polarized light microscopes. This property of mineral Cuprosklodowskite makes the mineral an impressive specimen. Rare mineral collectors seek after Cuprosklodowskite due to its rarity and impressive splendid beauty when evaluated with the aid of polarized microscope for mineralogists.

 

            Mineral Cuprosklodowskite is commonly found exhibiting dark green color that could appear more fascinating when specimen is closely  evaluated with the aid of polarizing light microscope used in optical mineralogy. Cuprosklodowskite is most commonly found exhibiting vitreous to silky luster when it is evaluated in reflected light of polarized microscope used in optical mineralogy. Mineral Cuprosklodowskite is also most commonly found showing perfect cleavage in only one direction when specimen is closely evaluated with the aid of petrographic polarizing microscopes for mineralogists. Cuprosklodowskite is also most commonly found exhibiting uneven fracture when it is evaluated under several adjustments on the aperture diaphragm of polarized microscope used in optical mineralogy. The flat surfaces of the crystal are fractured in an uneven pattern and are commonly visible under petrographic polarizing microscopes used in optical mineralogy. The specific gravity measure of the mineral usually gives an approximate value of 3.8 grams per cubic centimeters, which is considered above average for translucent minerals. The hardness measure of mineral Cuprosklodowskite when it is evaluated using the Mohs scale method is usually 4. Cuprosklodowskite is most commonly found leaving a green streak when mineral specimen is rubbed on a white porcelain streak plate.

 

            Most Cuprosklodowskite mineral crystals are found transparent to translucent in appearance. The crystal habit of mineral Cuprosklodowskite as described in the field of optical mineralogy commonly includes typically fibrous tufts and crusts that can be more clearly exhibited when evaluated with the aid of petrographic polarizing microscopes. Cuprosklodowskite minerals can be also found in acicular crystals in radial aggregates that are usually very splendid when viewed under polarized light microscopes used in optical mineralogy. Cuprosklodowskite is commonly found showing a moderate surface relief when mineral is examined in plane light of polarizing light microscopes used in optical mineralogy. Cuprosklodowskite is commonly found showing biaxial negative figure when mineral is evaluated between crossed nicols of polarizing light microscope for mineralogists. The maximum birefringence found exhibited by mineral Cuprosklodowskite is usually found ranging from 0.010 to 0.012. The refractive indices of Cuprosklodowskite when it is evaluated in plane polarized light are usually found ranging from 1.654 to 1.667. Mineral Cuprosklodowskite is fluorescent under ultraviolet light Mineral Cuprosklodowskite is a radioactive mineral. Thus, it is highly recommended to store the specimen away from other minerals that are prone to be affected by radioactivity. Human exposure should be also limited. There is no specific data on the toxicity and health dangers for mineral Cuprosklodowskite. However, the specimens of this mineral species should be treated with great care and use of sensible precaution is advised upon handling them.

 

            Mineral Cuprosklodowskite is most commonly found associated with other interesting minerals such as uraninite, sklodowskite, brochanitite, dioptase and uranophane. The best field indicators of mineral Cuprosklodowskite usually include color, crystal habit, radioactivity, locality and fluorescence. Mineral Cuprosklodowskite is commonly found as a secondary mineral formed by the alteration of earlier uranium minerals, both in situ and after transport of solutions. Mineral Cuprosklodowskite notably occurs at some famous localities including Amelal Morocco, San Juan Co., Utah and the Musonoi Mine in Shaba, Zaire. Cuprosklodowskite minerals can be also found in France and England.
