Leinegraben

from Wikipedia, the free encyclopedia

The Leinegraben is a lowland in southern Lower Saxony and , to a lesser extent, in northeast Hesse . It extends about 48 km in an approximately south-north direction along the eponymous Leine from Arenshausen via Friedland , Göttingen and Northeim to Einbeck .

The core ditch between Friedland and Northeim, which is up to 8 km wide and where a fault is crossed, is characterized by particularly distinctive fault edges and is 34 km long. A narrowing to two kilometers at Nörten-Hardenberg divides it into the Göttinger Leinegraben in the south and the Northeimer Leinegraben in the north.

In Einbeck leash digging goes to the northeast flowing into the Ilme Valley of Ilme and its tributaries over, with whom he the natural spatial main unit Leash Ilme sink forms. Immediately to the east of Einbeck, the Leine leaves the valley via a breakthrough valley between Salzderhelden and Kreiensen .

The Leinegraben also forms a geological structural space, delimited somewhat differently , which leaves the Leine catchment area to the south and reaches the Werra to the southeast of Witzenhausen .

geology

Keuper can be found in the subsoil of the Leinegraben , while to the east and west a layered landscape of red sandstone ( Hardenberg Castle ) and shell limestone ( Plesse Castle ) rises up, assigned to the Leinebergland . In the normal sequence of layers one would expect the younger Keuper to be above the other two layers ( Germanic Triassic ).

The Leinegraben is now mostly interpreted as a rift valley in the Mediterranean-Mjosen zone with " Rhenish strike ". Similar to the Upper Rhine Graben , the Leinegraben is accompanied in the west by basalt deposits ( Hoher Hagen , quarries near Adelebsen ). While the difference in height can usually be seen very clearly at the fault on the east side ( Wieter near Northeim, Göttinger Wald ), the increase in the west is less pronounced.

Some Rhaetian ridges have remained within the trench .

Natural structure

The Leine-Ilme-Senke as part of the Lower Saxon mountainous region is structured as follows:

Importance to humans

The Leinegraben is covered with loess soil and enables good agriculture.

As a trade route, the Leinegraben was of secondary importance in the 10th century at the latest with the flourishing of shipping on the parallel Weser . Where it was crossed by east-west roads, trading and Hanseatic cities such as Einbeck, Northeim and Göttingen developed. The royal palace of Grona in Göttingen-Grone was also located above an entrance to the Leinegraben.

Today the old north-south route and the high-speed route Hanover – Würzburg run in sections through the Leinegraben, the federal highway 7 runs from Northeim to Göttingen-Weende above its western edge.
