Pushcharovskite is a rare mineral that belongs to the complex phosphate group. It is characterized by its deep blue to blue-green color and crystalline structure. The mineral was named after its discoverer, Russian mineralogist Petr Aleksandrovich Pushcharovsky.
In terms of its chemical composition, pushcharovskite is an hydrated iron calcium nickel phosphate. Its formula can be expressed as (Ca,Zn)(Fe,Fe,Ni)(PO4)2·4H2O. Due to its composition, pushcharovskite falls under the category of secondary minerals, which are formed as a result of weathering and oxidation processes in ore deposits.
Pushcharovskite is typically found in nickel and copper deposits associated with hydrothermal mineralization. It often occurs as small, prismatic or tabular crystals embedded in a host rock. The mineral's luster is vitreous to pearly, and it displays a perfect cleavage along its crystal surfaces.
While pushcharovskite is considered rare, its distinctive color and crystal structure make it valuable to collectors and researchers. It has been discovered in various locations around the world, including Russia, Canada, Poland, and Serbia.
In summary, pushcharovskite is a rare complex phosphate mineral that is characterized by its deep blue to blue-green color. Its chemical composition consists of iron, calcium, nickel, and phosphate ions. The mineral is primarily found in nickel and copper deposits associated with hydrothermal activity.
