Jh eingestürzten Bergbaus auf Zinn mit den umliegenden Halden (Beran 2006). Diese stammen sowohl aus dem geschichtlichen Bergbau, wie auch aus den Aktivitäten -untertage und übertage- in jüngster Zeit (20. Jh., Einstellung des Betriebs der Stannum 1991, Bergbau auf Wolfram und Zinn). Auf der Fundstellenseite wird auf einen Beitrag des Förderbvereins der Lithothek verlinkt. Diese haben die Fundstelle in der Lithothek aufgearbeitet. |

The mineral calcite, however, differs from Aragonite due to its internal crystal structure. While the crystal system of calcite is trigonal, the system of aragonite is rhombic. Dense masses of small aragonite crystals are difficult to distinguish from calcite, but they are larger, they show a distinct habit. A lot of chapters in this portrait will give you much more details about this interesting mineral. Written and investigated by Peter Seroka. (Article in german) |

The mine complex extends over 21.2 square kilometers and is one of the largest gold deposits in Europe. The tunnel system in the underground is several hundred kilometers long and was used until a few years ago. Already in Roman times the tunnels had a length of 145 km. |
