Geological

e.g. The origin of the basalt of Stolpen

The slag volcano of Stolpen broke out before about 25 million years ago. Here in Stolpen struck by a basic lava from the upper mantle to much older Proterozoic Lausitzer granodiorite. This was due to large tectonic processes in the Tertiary, which generated a large volcanic belt associated with earthquakes. These include, for example, other Basalt deposits in Saxony as the Löbauer Berg, the Kottmar that Landeskrone in Görlitz, the Great Winterberg in the Elbe Sandstone Mountains, the Scheibenberg or Hirtstein in the Ore Mountains. In fact, these tertiary basalt belt is much larger - this, for example, includes the basalts of the Bohemian Uplands and the Doupov Mountains in the Czech Republic, the basalt deposits in the Rhön, the Westerwald, the Odenwald, the Seven Mountains and many others. The actual volcano of Stolpen no longer exists today - he was removed from the weathering. Today only can be seen with its impressive columns of the feed vent of the volcano slag.
