Zubkovaite
Zubkovaite is a rare phosphate mineral with the chemical formula calcium tricopper tetraarsenate. It belongs to the monoclinic crystal system and is classified as a phosphate mineral. This mineral exhibits a vitreous luster and typically displays a greenish or yellowish color. With a hardness of approximately 4 on the Mohs scale and a moderate density, zubkovaite is notable for its unique chemical composition and crystal structure. It is part of the broader group of copper arsenate minerals, which are relatively uncommon in the mineral world.

Etymology
Zubkovaite is named after Natalia V. Zubkova, in recognition of her contributions to mineralogy. The mineral was officially approved by the IMA, but no specific discovery year is provided.
How to recognize it
Zubkovaite can be identified by its moderate hardness of about 4 on the Mohs scale, its greenish or yellowish color, and its vitreous luster. It typically does not leave a distinct streak. Due to its rarity, it is not commonly confused with other minerals, but its unique chemical composition and color can aid in identification.
Trivia
Zubkovaite is a rare mineral with a unique chemical formula involving calcium, copper, and arsenate. It is named after a notable mineralogist, Natalia V. Zubkova, which is a point of interest in its nomenclature. The mineral's monoclinic crystal system adds to its distinct structural characteristics.
