Geology
The most important lodes in the region around Wieden are the fluorite-barite lodes known as Tannenboden, Anton, Werner II, Hoffnung and Finstergrund, which all run in a north to south direction. The latter is 3.5 km long and the most significant hydrothermal lode in the area. The visitor mine (Gallery 5) runs along this lode for 430 metres. Its thickness varies between a few centimetres and 4 metres. About 1 metre was mined. The ore deposit is a hydrothermal fluorspar-baryte lode, in places containing rich sulfide ores. The country rock is formed by paragneisses and migmatite. [1]
