Keuperbergland

The Keuperbergland (more rarely Keuperwaldberge ) is part of the southern German layered landscape and covers an area of ​​around 3200 square kilometers .

Keuperstufe above the Heckengäu on the western edge of the Schönbuch

From southwest to northeast, the Keuper Hills include Kleiner Heuberg , Rammert , Schönbuch , Glemswald , Strom- and Heuchelberg , Schurwald and Welzheimer Wald , Swabian-Franconian Forest Mountains , Frankenhöhe , Steigerwald and Hassberge . The most south-westerly Keuperschicht stage in the Baar area has no name of its own due to its small size.

Natural structure

The Keuperschichtstufe in the northwest of the Swabian-Franconian Forest Mountains near Löwenstein. The steps are easily recognizable from the terrain profile of Wolfertsberg sloping to the left (west) in the center of the picture: At the top (right) the wooded parlor sandstone, steeper drop in the highest vineyard locations in the upper colorful marls, elongated plateau on pebble sandstone, again steeper drop (partly still wooded) in the lower colorful marls to the plateau of the reed sandstone, which has recently been strongly reshaped by the reorganization of the vineyards. Gipskeuper forms the valley floor .

The Keuperbergland is divided into three natural spatial main unit groups and the three-digit main units listed below (units that are only to a small extent on Keuper are in italics) as well as, subordinate, the following orographically separated mountain ranges (depressions and edge heights left out):

• (to the south-west German layer level country )

Except for electricity and Heuchelberg , the north of the Schönenbuch and Glemswald -Lia landscapes keuper and outside of the shell heavy lie Gäuen, the scenery in the list above along the Albtrauf from which it by liaslastige separated Vorländer, arranged in the direction of the northeast .

landscape

The eponymous Keuper , the highest and youngest lithostratigraphic group of the Germanic Triassic, is decisive for the landscape . It shows a changing variety of deposits of sand and sea deposits.

Most of the Keuperbergland is forested, as the soil on Keuper is not very fertile. Clearing islands are mainly found on the fertile loess or lias soils.

The very steep notch valleys typical of the Keuperbergland are referred to here as " blades ". Such blades appear in the petrographically harder sandstone layers of the Keuper, for example in the parlor sandstone . These rocks can offer sufficient resistance to the erosion forces (above all side erosion) of the water. In the less erosion-resistant rocks of the Keuper such as clays or marls , on the other hand, the valley is more pronounced, so that there are much wider shapes.
