| Comments: | This mineral has been reported from the vein-type ore bodies (Chen, 1981). However, all traded specimens of alleged silvery fibrous and acicular "galenobismutite" that have so far been analyzed turned out to be stibnite or one of the sulfosalts. According to Jensen (2009), analyses of a large number of samples from all levels of the mine never disclosed the presence of any bismuth bearing minerals. These findings do not necessarily discredit all earlier reports, since it has to be kept in mind that all parts of the deposit were mined long before the first specimens appeared on the western market in the early 1990s, that mineralization zoning is a common phenomenon in intrusion-related deposits, and thus a different mineral assemblage may have been found in parts that are now mined out. They indicate however, that bismuth minerals are rare at this locality, if they can still be found at all. |
