Mühlhausen – Orlamünder plaice

from Wikipedia, the free encyclopedia
The Mühlhausen – Orlamünder Scholle southwest of the center of the Thuringian Basin

The Mühlhausen – Orlamünder Scholle is located entirely in Thuringia , south-west central of the four Hercynian , ie from northwest to southeast running main floes in the area of ​​the Thuringian Basin and its edge plates .

It stretches from the limestone higher layers of the western Duen , the Upper Eichsfeld and the Hainich over the Keuper of the Thuringian basin in Mulhouse and the limestone-ridge Fahnersche height and Keuper pool at Erfurt in the shell of the Ilm-Saale-board in the strict sense , together with Buntsandstein-Insel Tannrodaer Waldland near Tannroda , until it penetrates over the red sandstone of the Saale-Elster sandstone slab between Rudolstadt and Orlamünde into the Orlasenke near Pößneck , which as a Zechstein belt directly flanks the East Thuringian slate mountains .

Limitations

To the southwest, the Mühlhausen – Orlamünder Scholle is bounded by the Eichenberg – Gotha – Saalfelder fault zone , beyond which the Treffurt – Plauer Scholle of the western Thuringian mountain and hill country adjoins; to the north-west it borders on the multifaceted south-west continuation of the Ohmgebirgs rift zone on the Eichsfeld plaice . To the northwest it borders on the Schlotheim – Leuchtenburg fault zone , beyond which the Bleicherode – Stadtrodaer Scholle of the north-eastern Thuringian basin joins.
