Ancient iron and copper Mine, closed in 1899.
Located 3 km N of Hirschberg.
Note: Ullersreuth is not in Saxony (as given in many references).
Note on the "liroconite" reported in the old literature:
It was originally reported by Breithaupt, A. (1841): Vollständiges Handbuch der Mineralogie, Bd. 2, Dresden und Leipzig, p. 158, who later, however, noted that this was a wrong identification and that the sample was in fact "Tagilite" (= Pseudomalachite): Breithaupt, A. (1865): Mineralogische Studien. 3. Tagilit.- Berg- und hüttenmännische Zeitung 24, 309-312
A SXRD study of an old sample in the collection of the Natural History Museum Vienna has confirmed this (U. Kolitsch).
36 valid minerals. 1 (TL) - type locality of valid minerals. 1 erroneous literature entry.
This geological map and associated information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This does not necessarily represent the complete geology at this locality but it gives a background for the region in which it is found.
