The chemical formula of mineral Kulanite is indicated by Ba(Fe, Mn, Mg)2Al2(PO4)3(OH)3 or Barium Iron Manganese Magnesium Aluminum Phosphate Hydroxide. Kulanite is actually a Phosphate mineral. Kulanite was actually named after Alan Kulan (1921-1977), a prospector who found the first specimen. The mineral species was first discovered in 1976 at its type of locality at Rapid Creek, Yukon Territory, Canada. Mineral Kulanite 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 Kulanite is most commonly used a mineral specimen. Kulanite is actually a very rare barium phosphate mineral. It is only one of those several interesting rare minerals from Yukon Territory that are making their way into the mineral market.

 

            Mineral Kulanite is most commonly found exhibiting a green to blue color that could appear more interesting when viewed with the aid of polarized microscopes used in optical mineralogy. Kulanite is also most commonly found exhibiting vitreous luster that could be more clearly exhibited when mineral specimen is closely viewed in reflected light of petrographic polarizing microscope for mineralogists. Mineral Kulanite is also commonly found showing good cleavage in two directions that could be found more clearly visible when specimen is viewed under polarizing light microscopes used in optical mineralogy. The specific gravity measure of the mineral usually gives an approximate value of about 3.9 grams per cubic centimeters, which is considered above average for translucent minerals. The hardness measure of mineral Kulanite when it is evaluated using the Mohs scale method is usually found 4. Kulanite is commonly found leaving a white streak when specimen is rubbed on a white porcelain streak plate. 

 

            Most crystals of Kulanite mineral are found transparent to translucent in appearance. The crystal habit of mineral Kulanite as described in the field of optical mineralogy usually includes flattened striated blades or radiating acicular crystals that are often found splendidly exhibited under polarizing microscopes for mineralogists. However, Kulanite crystals are quite uncommon. Kulanite is more commonly found as crusts or earthy masses. Sometimes Kulanite mineral can be found forming rosette or bundles tabular aggregates resembling rose flower petals that can be more majestically exhibited when viewed with the aid of petrographic polarizing light microscope used in optical mineralogy.

 

            Kulanite is most commonly found exhibiting a high surface relief when it is evaluated under several adjustments on the aperture diaphragm of the polarizing microscope used in the field of optical mineralogy. Kulanite is most commonly found showing biaxial positive figure when specimen is closely viewed between crossed nicols of polarized light microscope for mineralogists. The refractive index of mineral Kulanite when it is evaluated under polarizing light microscope used in optical mineralogy is usually found ranging from 1.703 to 1.723. The maximum birefringence of mineral Kulanite when it is evaluated between crossed polars of petrographic polarizing microscope is usually 0.020. Kulanite also shows weak dispersion when viewed under polarized microscopes used in optical mineralogy. Kulanite crystals are non-florescent in ultra violet light. There is no specific data found on the toxicity and health dangers for mineral Kulanite. However, the specimens of this mineral species should be treated with great care and use of sensible precaution is advised upon handling them. Mineral Kulanite is a non-radioactive mineral species.

 

            The best field indicators of mineral Kulanite usually include density, color, crystal habit and locality. Mineral Kulanite is commonly found in cavities in phosphate rich shales. It usually forms series with penikisite. Mineral Kulanite notably occurs at the Rapid Creek, Yukon Territory, Canada.
