Geological map of Lower Saxony 1 : 50 000 - Basic map
Description
The geological conditions of Lower Saxony are shown in the Geological Map of Lower Saxony 1 : 50 000 - Basic map (GK50) presented nationwide in a homogeneous, professionally coordinated form and in current nomenclature.
The map provides information on the distribution, nature and sequence of rocks to a depth of two meters below the surface of the terrain.
In the case of solid rocks, conclusions can usually be drawn about the continuation of these rock sequences into greater depths. The thematic foundations of the map construction are primarily the map sheets of the Geological Map of Lower Saxony 1:25 000 (GK25) as well as digital data sets derived from them. Information from soil maps as well as up-to-date data from the fields of soil science/soil estimation as well as peat and peat science are also incorporated. In the map image as well as in the associated legend, stratigraphy (ageing) and genesis (type of origin) are shown and described for each geological unit. The legend also contains information on the main and secondary components of Petrography (the nature of the rocks) as well as the lime and humus content of the individual layers.
All units shown and numbered in the map image are abbreviated to the symbol key geology (PREUSS et al. 1991) is explained.
The presentation of the geological facts in the base map is subject to certain rules. Rocks at the surface of the terrain of at least 2 meters thickness are characterized by surface colors, overlapping cases of several layers with beam hatching. Horizontal beam hatchings indicate layer sequences that consist exclusively of loose rocks, diagonally arranged beam hatchings refer to loose rock layers over solid rocks. Wide hatches refer to the rocks on the surface of the terrain; underlying layers are characterized by a thinner hatching. Surface colors as well as colors of the hatchings characterize the respective rock type. In order to clarify the natural geological conditions, the original distribution of the rocks is shown in areas with intensive development, although this may be changed by anthropogenic measures (e.g. landfilling).
