Manganosite General Category Oxide mineral Chemical formula Manganese oxide, MnO Strunz classification 04.AB.25 Identification Color Emerald-green, becoming black on exposure to air Crystal habit Granular to massive: Crystals rare Crystal system Cubic Cleavage Perfect on [100], [010] and [001] Fracture Fibrous Mohs scale hardness 5 - 6 Luster Vitreous, adamantine to dull Streak Brown Diaphaneity Transparent to translucent to opaque Specific gravity 5.18 Optical properties Isotropic References [1][2][3] Manganosite is a rare mineral composed of manganese(II) oxide MnO. It was first described in 1817 for an occurrence in the Harz Mountains, Saxony-Anhalt, Germany.[2] It has also been reported from Langban and Nordmark, Sweden and at Franklin Furnace, New Jersey. It also occurs in Japan, Kyrgyzstan and Burkina Faso.[3]
It occurs in manganese nodules. It also occurs as alteration of manganese minerals such as rhodocrosite during low oxygen metamorphism and metasomatism[3]
