Akhtenskite
From Wikipedia, the free encyclopedia
Akhtenskite (Manganese Smoker[1]) is a mineral that was named after the Akhtensk deposit. The deposit can be found in Russia, where it was first discovered and noted in 1979.[2][3][4] It can be found in the Akhtensk brown ironstone deposit, in the southern Ural Mountains, on Mt. Zarod, on the Sikhote-Alin Mountains, and in the Primorskiy Kray. All of these locations can be found in Russia.[5]
Akhtenskite is not radioactive.[3] Its crystals are usually hexagonal in shape, with flakiness and plating, usually because of the fact that it replaced a mineral.[5] It occurs in mixtures in "psilomelane" with other manganese oxides in an iron oxide deposit, most likely bacterially altered from a previous mineral in the Akhtensk deposit. It also occurs in crustings of ferromanganese minerals on oceanic rocks.[3] Its chemical makeup is 63% oxygen and 37% manganese.[4] However, it very rarely occurs.[6]
Some minerals that are commonly associated with Akhtenskite are: todorokite, pyrolusite, nsutite, goethite, and cryptomelane.[7] It has a specific gravity of 4.78.[8]
