Hello, I am [G. Edward Johnson] and have been on wikipedia since 2002. My first edit with this account was on March 22, 2002 to create the page for The Eyes of the Dragon by Stephen King. (I may have edited some pages anonymously before then, I just don't remember.) I have recently been adding photos to articles as well as short article descriptions.
Hübnerite is a mineral consisting of manganese tungsten oxide, with a chemical formula MnWO4. It typically occurs in association with high-temperature hydrothermal vein deposits and altered granites and in alluvial deposits. Hübnerite is the manganese endmember of the wolframite solid solution series, with ferberite (FeWO4) the opposite iron endmember. Color differences between members of the wolframite family are clear and marked, with the color of hübnerite varying from yellowish brown to reddish brown. It was first described in 1865 for an occurrence in the US state of Nevada and was named after the German mining engineer and metallurgist Adolf Hübner. This stacked image, composed of 38 individual photographs, shows red hübnerite crystals with quartz extracted from the Pasto Bueno mine in Pallasca Province, Peru.Photograph credit: Ivar Leidus
