Aleksite is a term used to describe a type of mineral that belongs to the orthorhombic crystal system. It is primarily composed of copper, vanadium, and oxygen, with the chemical formula Cu3(VO4)2. Aleksite typically forms prismatic or tabular crystals, which can be transparent to translucent with a vitreous to resinous luster. It exhibits a range of colors, including green, bluish-green, yellow-green, and brownish-green, often with a distinct pleochroism.
The name "aleksite" was derived from the mineral's original discovery site at the Aleksandrovskii Mine in the Ural Mountains of Russia. It was first documented in 1965 by G. N. V. Belov and V. V. Gibsher, and subsequently recognized as a unique mineral species.
Aleksite is considered a relatively rare mineral, typically found in vanadium-bearing hydrothermal copper deposits. It can be associated with other secondary copper and vanadium-bearing minerals, such as azurite, malachite, and decrespignyite-(Y). Optical and X-ray studies have revealed that aleksite has a distinct crystal structure, consisting of layers of copper-oxygen compounds and vanadium-oxygen compounds.
Due to its limited occurrence and unique composition, aleksite is primarily appreciated as a collectible mineral and often sought after by mineral enthusiasts. Its striking green hues and attractive crystal habits make it a valuable addition to mineral collections and can be admired for its aesthetic beauty.
