Hahnbacher Valley

from Wikipedia, the free encyclopedia

The area around Hahnbach in today's Amberg-Sulzbach district is known as the Hahnbacher Senke or Hahnbacher Mulde . The valley between Vilseck and Amberg through which the Vils flows was created by reversing the relief of the Hahnbacher dome (also known as the Hahnbacher Sattel ) and is assigned to the natural area of ​​the Upper Palatinate hill country .

Geography and geology

As a slightly hilly landscape, the valley is clearly demarcated from the surrounding heights. The morphology of the landscape changes significantly at the confluence of the Gibsbach in the Vils in the Amberg urban area. Here, the Vils crosses the Amberg – Sulzbacher fault zone, which runs from southeast to northwest, as an extension of the Saxon fracture fault of the pile .

The iron ore deposits parallel to the fault were examined in detail in the 20th century by the Maxhütte in Sulzbach-Rosenberg and the Luitpoldhütte in Amberg. The concession area of ​​the Luitpoldhütte extends southwest of the Markscheide near Neuhof along the line Häringlohe - Erzberg and Galgenberg - Mariahilfberg - Krumbach - Engelsdorf to Altenricht and to the former ore mines Haidweiher , Penkhof and Ebermannsdorf .

In a north-westerly direction, the fracture zone in the area of ​​the Maxhütte runs from the Erzberg via Schäflohe –Häringlohe– Eichelberg via Oberschwaig and Lobenhof .

The elevation center of the asymmetrical dome bulge is about 2 to 3 km north / northeast of Unterschwaig . If all the rock layers detectable in the border were still present, the dome would tower over the surroundings by around 380 to 450 m and reach a height of 800 m.

Topographic map

It should be taken into account that in the explanations of the geological map of Bavaria from the 1960s, the elevation data refer to sea ​​level .
