Huebnerite on Quartz Casapalca Peru
Hübnerite or hubnerite is a mineral consisting of manganese tungstate (chemical formula: MnWO4). It is the manganese endmember of the manganese - iron wolframite solid solution series. It forms reddish brown to black monoclinic prismatic submetallic crystals. The crystals are typically flattened and occur with fine striations. Typical occurrence is in association with high-temperature hydrothermal vein deposits and altered granites with greisen, granite pegmatites and in alluvial deposits. It was first described in 1865 and named after the German mineralogist, Adolf Huebner.
