In der Nähe befindet sich das bekannte Ausflugsziel "Prinzenhöhle". Das Schachtgelände einschließlich der mächtigen Halden erstreckt sich vom Ostufer der Zwickauer Mulde zum einen über das fast vollständig verfüllte Kohlungsbachtal (Teilhalde 371/I) und zum anderen bis hin an die Felskuppen der Hohen Warte in ... ein Beitrag von Thomas Uhlig |

Inclusions can be a sort of fingerprint of the place of dicovery. Thus inclusions show us under which geologic conditions minerals had formed. This allows conclusions on the place of discovery. The article deals with the different kinds of inclusions, her conditions of build, which minerals do often have inclusions and how they appear. (Full text in german) |

Olivine belongs to the olivin-groupe whose end-members are calcio-olivine and tephroite. Forsterite is a magnesium silicate; fayalite an iron silicate. If commonly is spoken of olivine, it is usually a more or less iron-rich forsterite. The color of olivine is generally yellowish green, olive green to black. You will find much more interesting details in our portrait about this common mineral series. 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. |
