General Geological Map of the Federal Republic of Germany 1:200,000

The map series General Geological Map of the Federal Republic of Germany 1:200,000 (GÜK200) is the result of cooperation between the State Geological Surveys of the Federal Republic of Germany (SGD), the Geological Surveys of neighbouring countries and the Federal Institute for Geosciences and Natural Resources (BGR). The GÜK200 displays the surface geology of Germany and adjacent areas of neighbouring countries on 55 map sheets. The map sheets show the regional dissemination of more than 3800 geological units. The geological units contain information on stratigraphy (age), genesis and petrography (composition) of the rocks. Each printed/scanned map sheet contains one or several geological cross-sections which give an insight into the subsurface. The digital data of the map series are stored separately for each map sheet. According to this geological units/polygons, their boundaries, tectonic linear elements and, if present, ice sheet boundaries are saved as a discrete layer in a shapefile for the single map sheets. The attributes of the geological units contain information – like in the printed map sheets – on stratigraphy, genesis and petrography of the rocks.
