Geological Map of the Federal Republic of Germany 1:200,000 (GÜK200) — CC 3134 Wittenberge

Blatt Wittenberge is taken entirely by the North German lowlands, with the Mecklenburg Lake District being cut to the northeast of the map section. The morphology of the northern German lowlands is characterised by glacial influence. As several glacial series (basic moraine, final moraine, sander, Urstrom valley) are overlapping, the landscape is richly shaped with a variety of lakes. The area depicted between Elbe in the southwest and Mecklenburg Lake District in the northeast is covered by a quaternary sediment ceiling. The pleistocene deposits of the Saale and Vistula cold periods include: glacial pelvic sludge, loam of the base moraines, deposits of the final moraines, fluviatile and glazifluviatile deposits as well as Aeolian flight and dune sands. Interglacial warm periods (Eem and Holstein) are evidenced by limnic sediments such as lime and detritus mudde. In the lowlands, the pleistocene deposits are partly superimposed by holocene river, moor and lake sediments. The quaternary sediment ceiling is very powerful in the North German lowlands. Only isolated and regionally narrowly limited, older layers of the prequarter subsurface (tertiary or Cretaceous sediments) are revealed. In addition to the legend, which informs about the age, petrography and genesis of the geological units, an overlay scheme clearly summarises all surface-close superpositions. Two profile cuts provide additional insights into the structure of the subsurface, with different salt structures being cut on. The first profile crosses the salt sticks of Krask, Werle, Helle and Netband in its northwest-southeast course. The second cut begins in the south and cuts in the north direction the salt stock Werle and the salt cushion Schlieven.
