|location||Saxony-Anhalt , Germany|
The Flechtinger mountain range is about 20 by 20 kilometers. It is bordered in the west by the Aller , in the north by the Spetze , a right tributary of the Aller, in the northeast by the Valley of the Ohre , in which the Mittelland Canal runs, and in the south by the Beber , a tributary of the Ohre.
One of the highest peaks of the Flechtinger mountain range is Ivenrode .the Butterberg near the place
In contrast to its surroundings, there are geologically old rocks on the surface of the Flechtinger ridge. This makes it one of the northernmost hard rock deposits in Germany, as northern Germany is almost completely covered by loose rock of the Quaternary . The ridge is mostly built up from volcanic rocks and sedimentary rocks from the Carboniferous and Permian . Some of them are extracted in large quarries.
From a regional geological point of view , the ridge is part of the Flechtingen-Roßlauer Scholle , which extends in the northwest from the Drömling valley to the southeast to Magdeburg and on to Roßlau . Another well-known prominence of this floe is the Magdeburg cathedral rock , which continues as a threshold in the Elbe and noticeably increases the flow speed of the Elbe.
The Flechtinger Ridge is the northernmost basement elevation in front of the North German Plain and thus also in front of the deeper basin areas of the Eocene - Oligocene North Sea in the Lower Elbe region. Its north-eastern edge is formed by a distinctive fault zone, the Haldensleben and Wittenberg faults, which are also known as the "Central German Main Abort". Immediately north of it, as in the Altmark , the rocks of the Tertiary are up to 1000 m deeper than south of the ridge or on the ridge itself.
