 The quarry on the Hirschentanz, in the core area you can see the columnar solidified basalt of the former lava lake , the reddish areas are slag and the weathered granite appears as a yellow layer on the right edge of the picture. The stone blocks in the foreground are frozen lava bombs that can often be found in the wide area around the volcano. |

The Hirschentanz (originally 644 m above sea level , the summit has been largely removed by mining and the mountain is only 624 m high) is a densely wooded basalt cone south of Preisdorf in the Upper Palatinate district of Tirschenreuth and belongs to the Reichsforst in the Fichtelgebirge .
geography
The Hirschentanz is separated from the A 93 motorway and the Weiden – Oberkotzau railway from Pechbrunn and Steinwald in the southwest . The village of Großbüchlberg near Mitterteich is located around 2.6 km southeast of it .
geology
A large basalt eruption area lies between Marktredwitz , Mitterteich, Konnersreuth and Seußen . It is the largest extinct volcano in the Fichtel Mountains. In the Miocene , liquid basalt came up through the granite and phyllite . At the time of the eruption, the landscape here was relatively flat with deeply weathered granite rock underground. Rising magma came into contact with the groundwater and exploded with violent eruptions ( phreatomagmatic phase ). The brightly colored, fine-grained deposits were ejected from the granite adjacent rock together with basalt. They formed a flat crater wall around the young funnel shape of the volcano.
A clear change to dark colored, chaotic masses with large blocks of basalt marks an important change in the development of the youthful volcano. Less and less groundwater reached the explosion site. Therefore, the volcano now ejected shreds of basalt magma at irregular intervals, which lay as porous slag over the crater and its outer wall ( Strombolian phase ). Gradually the volcano calmed down and the explosions stopped. The magma rose to the surface and formed a lava lake in the crater. When it solidified, the characteristic basalt columns formed . Further supplies of magma caused the crater to overflow and lava flows poured into the surrounding area ( effusive phase ).
economy
There are two large basalt quarries in the summit region .
