Geological Map of the Federal Republic of Germany 1:200,000 (GÜK200) — CC 4718 Kassel

Blatt Kassel depicts the Rheinische Schiefergebirge in the southwest, the Münster Basin and its confining mountain ranges to the west, the North Hessian Tertiärsenke on the southern edge, the colorful sandstone landscape of Solling in the eastern part, the Hils and Sackwald mountain ranges in the northeast. Mesozoic sedimentary rocks dominate the leaf. The Münster basin is filled with limestones and marlstones of the Upper Cretaceous. In the border area (Teutoburg Forest and Eggegebirge) older layers of the Triassic to Lower Cretaceous occur. They are severely broken and dismembered, some of which complicate the geological construction. In the hinterland of the mountain ranges, in the east direction, sediments of the Trias dominate (bunt sandstone, mussel limestone, keuper). The sand and clay stones of the Bunt sandstone in Solling, Reinhardswald or Bramwald were deposited extensively in a mainland basin that covered large parts of Central Europe. In the area of the North Hessian Tertiärsenke, on the southern edge of the map leaf, the Buntsandstein is covered extensively by quaternary curler sediments and volcanoites. Endogenous forces in the tertiary led to a lowering of the area, the sedimentation of partly marine sands and clays, and the intrusion of basaltic magma. Overlays by glacial sediments are widespread throughout the area (periglaziary, glazifluviatile and eolian deposits of the Saale and Vistula cold seasons). Larger outcrops of Jura and chalk can still be found in the northeast corner of the map leaf. Hils and Sackwald are among the Mesozoan mountain ranges that form the southern edge of the northern German lowlands. In both cases, it is a relief reversal, i.e. the former hollow structures, filled with Jurassic and Cretaceous sediments, are today characterised by tectonic processes and weathering. The foothills of the Rheinische Schiefergebirge in the southwest part of the map sheet are characterised by folded and diversified sedimentary rocks of the Paleozoic (Devon and Carbon). The Devonian rocks dominate the central part. To the north and south, sedimentary rocks of the carbon are joined. In the east, deposits of the Zechstein form the boundary of the Rheinische Schiefergebirge. In addition to the legend, which informs about the age, genesis and petrography of the represented units, a geological section provides insights into the structure of the subsurface. The southwest-north-east profile begins in the mass limestone of the Rheinische Schiefergebirge, crosses the edge of the Münster chalk basin and crosses the triassic cover including Solling as well as Jura and chalk of Hils and Sackwald.
