The Hirschau-Schnaittenbacher Basin , rarely also called the Hirschau-Schnaittenbacher Basin , is a natural sub-unit in the northern Upper Palatinate hill country .
Natural allocation and structure
The Hirschau-Schnaittenbacher Senke is a subordinate natural area in the north of the Upper Palatinate hill country .
Since sheet 154/155 Bayreuth of the single sheets 1: 200,000 for the manual of the natural spatial structure of Germany has not been published, there is no detailed breakdown for the northern part of the Upper Palatinate hill country . However, the Hirschau-Schnaittenbacher Senke is regularly mentioned in relevant specialist literature as a natural area. In particular, it is listed by name in the southern neighbor at sheet 164 Regensburg as the northern boundary of the Naab Mountains .
geography
The Hirschau-Schnaittenbacher Senke extends from west to east between the Kohlberg ridge in the north and the Naab Mountains in the south. It is separated from the Kohlberg ridge by the Luhe line . In the east borders the Upper Palatinate Forest , which, like the Naab Mountains, is part of the crystalline basement , the border between the Upper Upper Palatinate Forest / Naab Mountains and the Hirschau-Schnaittenbacher Senke is also the border between the crystalline basement ("primary rock") and the Mesozoic foreland .
geology
In the time of the middle red sandstone , the Germanic Basin extended from the north into what is today the Hirschau-Schnaittenbacher depression. To the south and east of the Hirschau-Schnaittenbacher Senke, the Germanic Basin was bounded by the basement , which mainly consists of gneisses and Variscan granites . Rivers transported from these high areas (the grain composition corresponds to the sedimentation of a flowing body of water) deposited large amounts of decomposed crystalline rock and deposited it in the Germanic basin. The robust quartz grains survived the long way to the central basin areas, which is why you will find mostly monotonous sandstones there. The significantly more feldspar-rich sands ( arkoses ) deposited at the edge of the basin in a huge delta formed the starting material for the kaolin deposits in the Hirschau-Schnaittenbacher depression. The process of kaolinization probably began during the sedimentation in the red sandstone .
The deposit consists of 30-40 meter thick sediment packages that dip from south to north at around 10 degrees. The buildable (over 12% kaolinite ) main deposit has an east-west extension of 2.6 km. This makes the deposits in the Hirschau-Schnaittenbacher Senke one of the most important continental kaolin, quartz sand and feldspar deposits in Europe.
For the " Geotope Day" in 2007, the Bavarian State Office for the Environment included the kaolin pits of the Amberger Kaolinwerke Eduard Kick in the list of the most beautiful geotopes in Bavaria .
