Geological Map of the Federal Republic of Germany 1:200,000 (GÜK200) — CC 7126 Nürnberg

Blatt Nürnberg is taken almost entirely by the southern German strata landscape. On the southern edge are parts of the Swabian Alb, on the Ostrand parts of the Franconian Alb. In addition, the Nördlinger Ries is open at the southern edge of the map. In the area of the southern German layer stage landscape, characteristic layers of the mesozoic (mushell lime to malm) formed by weathering and removal of flat-incoming sediment formations of the mesozoic. Sand, clay and marlstones of the keuper occupy the largest area in the area depicted. They dominate the card sheet with their brown coloring. In the northwest corner of the map there are more outcrops of mussel lime. In the southern half of the map sheet is the Jura of the Swabian Alb. In the lowlands and sinks, Lias, Doggers and Malm are covered by glacial deposits, mainly by Pleistocene weathering clay, solifluction debris, glazifluviatile gravel and sands or Aeolian loess or flying sands. To the south of Eichstätt, smaller chalk deposits (sandstone, quartzite) have been preserved, which deposit the Jura. The Nördlinger Ries, on the southern edge of the map, is interpreted as a crater of a meteorite that struck in the Upper Miocene (about 15 million years ago). The sink (with a diameter of about 20 km) is filled with tertiary sea sediments and Pleistocene loess. The Jura sediments in their marginal environment are heavily squeezed and deformed. In the Ries and up to a distance of 25 km, pieces of crystalline and sedimentary rocks of the subsurface can be found. In addition to the legend, which informs about the age, genesis and petrography of the represented units, a geological section provides additional insights into the structure of the subsurface. In the northwest-southeast course, the shallow mesozoic sediment layers of the southern German strata landscape are crossed.
