Wulfenite and Dravit (Slovenia) (1997, 2000)



The mineral wulfenit is lead molybdenum (Pb(Mo04)). According to its symmetric elements and crystal shape, which reflect a crystal structure, it belongs to the tetra logical pyramid type of symmetry. It was first mentioned as a "yellow lead ore" by Ljubljana's Jesuit professor Franz Xaver von Wulfen in 1785. The mineralogist Heidinger named the ore after Wulfen in 1845 calling it Wulfenit. In the Mezica valley wulfenit appeared in the cracks of the limestone and dolomitic of middle Triassic age together with galena, phalerite and calcite in the highest and oxidized parts of the lead-zinc mine.




The mineral dravite is magnesium tourmaline with a characteristic golden brown to dark brown, or almost black colour. It was named after the river Drava by the well-known Austrian imperial mineralogist Tschermak in 1883. The dravite appears in triangular or hexagon columns - prisms ending predominately in trigonal pyramids. The crystals mostly reach 1 cm in size.
