Geological overview map of the Federal Republic of Germany 1:200,000 (GÜK200) - CC 6334 Bayreuth

The Bayreuth sheet cuts into: the Bohemian massif with the Fichtel Mountains and the Upper Palatinate Forest, the Thuringian-Saxon and north-eastern Bavarian basement mountains and the southern German strata. Variscan folded rocks of the Precambrian to Lower Carboniferous are exposed in the southwest-northeast trending saddle and trough structures (Thuringian Synclinorian, Bergaer Anticlinorian & Vogtland Synclinorian) of the Thuringian-Saxon and Northeast Bavarian basement. The embedded complex of the Münchberger Gneissmasse represents a special feature: with its metamorphic rocks and its anchimetamorphic environment of Paleozoic layers in the Bavarian facies, it is both facies and tectonically in contrast to the surrounding Paleozoic in the Thuringian facies. In the center of the map sheet is the Fichtelgebirge with its Variscan granites and metamorphic pararocks (mica slate, gneisses, phyllites, quartzites). The Precambrian and Old Paleozoic sedimentary rocks were metamorphosed during the Variscan deformation. The Fichtelgebirge granites intruded post-Sudetic (330-310 ma) and post-Asturian (290-280 ma). In the area around Marktredwitz (Waldsassener Schiefergebirge) volcanic rocks pushed up in the Tertiary. While the Fichtelgebirge belongs to the Saxothuringian of the Variscids, the Upper Palatinate Forest in the southeast of the map sheet belongs to the Moldanubian. It is made up of metamorphites (gneiss, metabasite and anatexite) that emerged from the early Variscan overprint of Precambrian rocks. Here, too, extensive granitic plutonic rocks intruded in the Carboniferous. Slate Mountains and Bohemian Massif are cut off to the southwest by the Frankish Line, one of the major NW-SE fault zones in Central Europe. At the fault, the basement was z. T. lifted out more than 1000 m. In the south-west, the South German escarpment landscape with the Mesozoic of the East Bavarian Schollenland and the Franconian Jura joins. With its Jurassic sedimentary rocks, the Franconian Jura is one of the dominant mountain ranges in the southern German escarpment landscape. In addition to the legend, which provides information about the age, petrography and genesis of the units shown, three geological sections provide insights into the structure of the subsoil. In the northwest-southeast profile, the Franconian Forest, the Münchberg Gneiss Massif, the Fichtelgebirge and the Moldanubian Massif of the Bohemian Massif are crossed. Two northeast-southwest profiles illustrate the transition from the Franconian Forest or Fichtelgebirge to the southern German escarpment landscape via the fault of the Franconian Line.
