Former Quarry at Wolfsberg near Lüptitz

  • Geotope type: Abandoned quarry
  • Rocks: Pyroxene granite porphyry
  • Geological period: Permian (Rotliegend)

A quarry in which Lüptitz pyroxene quartz porphyry was mined from 1864 to 1930 is located at Wolfsberg, a hill rising up to 161 metres above sea level near Lüptitz. Since it was easy to process, the porphyry was valued as a building material, particularly as paving stone. The quarry has since been filled with water and is now being used as a fishing lake. The lake is approx. 160 x 70 metres in size and surrounded by a circular path. The water is between 11 and 15 metres deep. The geo cycling route Doberschütz-Wurzen leads past the foot of Spitzberg; the hill can be easily reached from Lüptitz.

Geotour: Geocycling route Doberschütz-Wurzen

The northern face of the quarry is protected as a large-scale natural monument. This exposed area is where two volcanic rocks came into contact. The coarser pyroxene granite porphyry, which has been mined at the quarry as the main rock, is characterised by coarse crystalline, here mostly as idiomorphically developed potash feldspar in a medium-grained groundmass of rocks. A fine crystalline pyroxene quartz porphyry with an andesitic composition intruded into these rocks. Geoscientists are currently investigating whether a closer genetic relationship exists between both volcanic rocks.

During the Elster and Saale glacial period about 350,000 to 125,000 years ago the Hohburger Land was “overrun” by inland glaciers. These glaciers were partly several hundreds of metres high. The frozen stones at the glacier base “scratched” the underground solid rock surface causing so-called glacial striation. On Wolfsberg itself glacial striation running approximately in an east-west-direction was found. Many of the striation have since been destroyed by the quarrying work. In Geopark Porphyrland well preserved glacial striation has survived, as for example the glacial and wind striation in the National Geotope on Kleiner Berg near Hohburg and at Spielberg near Böhlitz.
