Dataset description
On Blatt Hannover, the northern German lowlands to the south are bounded by mountain ranges of mesozoic sedimentary rocks, such as Weser and Wiehengebirge, Ith, Süntel, Deister, Osterwald, Hildesheimer Wald, Rehburger Berge and Bückeberge. The morphology of the northern German lowlands is characterised by glacial influence. The quaternary top layer of the map sheet is dominated by sliding loaming/mergeling of the Saale Cold Age basic moraine. There are often superimpositions due to Aeolian loess and flight sands of the Vistula cold season. In the rivers of Weser, Aue, Aller, Leine, Wietze and its tributaries, fluvitile sands and gravel of the Pleistocene and Holocene Auesediments also store. In the Hanover 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 shifting shifts, different mesozoic layers emerge in the mountain ranges, e.g. Hildesheim forest with colorful sandstone and mussel limestone; Weser and Wiehengebirge with Dogger and Malm; Rehburger Berge, Deister, Osterwald and Süntel with Malm and lower chalk. In the sinks, the mesozoic is superimposed by cenozoic curler sediments, predominantly 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 south-north cut illustrates the slight incidence of the mesozoic sediment layers, the rupture structure and the bulging of the Zechstein salts.
