Geological Map of the Federal Republic of Germany 1:200,000 (GÜK200) — CC 3926 Braunschweig

Blatt Braunschweig shows the North German lowlands with its south-bounding mountain ranges: Sauberge, Hainberg, Lichtenberge, Asse, Elm, Dorm, Elz and Lappwald. The morphology of the northern German lowlands is characterised by glacial influence. The quaternary top layer in the map section is dominated by sliding loams of the Saale Cold Age basic moraine. Often there is an overlay by soft-cold solubility and flight sands. Fluvitile sands and gravel of the Pleistocene and Holocene Auesediments are also stored in the waters of Oker, Aller, Jeze, Ohre and their tributaries. In the Braunschweig area, Mesozoan mountain ranges limit the North German lowlands to the south. From the Upper Jurassic to the tertiary, they were subjected to shiftwise tectonic deformations, in which numerous disturbances and a typical structure of fractures were formed. As a result of the shift adjustments, different mesozoic sediment layers bite in the mountain ranges: Sauberge with colorful sandstone; Lichtenberge and Dorm with colorful sandstone and mussel limestone; Aces with a sequence from Buntsandstein to Jura; Lappwald with Keuper and Jura; Oderwald and Hainberg with Cretaceous sediments. In the sinks, the Mesozoic canozoic curler sediments are mainly eolian and glazifluviatile sands of the Pleistocene and holocene Auesediments. In addition to the legend, which informs about the age, genesis and petrography of the represented units, a geological profile provides insights into the structure of the subsurface. The West-East section illustrates the slight incidence of the mesozoic sediment layers, the rupture structure and the bulging of the Zechstein salts.
