WMSThe 1 : 25 000 (GK25) geological map of Lower Saxony provides information on the distribution, consistence and sequence of rocks to a depth of two metres below ground. Additionally, information on the continuation of these consolidated rock sequences at greater depth can generally be derived. The stratigraphy (age) and genesis (method of formation and / or development) are shown and described for each geological unit in the map and in the corresponding description. In addition, the descriptions include information on the primary and secondary petrographic constituents (rock consistence), and on the lime and humus content of the individual layers. All units identified and numbered in the map are described using the abbreviations of the Symbolschlüssel Geologie (PREUSS et al. 1991). Representation of the geological conditions in the base map is subject to certain rules. Rock strata at least two metres thick and exposed at the surface are designated by a colour fill, and by hatched shading where several layers are superimposed. Horizontal hatching marks stratigraphic sequences comprising only unconsolidated rock, oblique hatching signifies unconsolidated strata overlying consolidated rock. Widely spaced hatching indicates rock exposed at the surface; underlying strata are marked by narrower hatching. Both fill and hatching colours indicate the respective rock type. The original distribution of the rocks is shown in order to emphasise the natural geological conditions in densely built-up areas, even though they may be modified as a result of anthropogenic activity (e.g. made ground). The GK 25 is available in two versions with differing accuracy: either as a detailed map (special mapping) or as a generalised map (manuscript map). The 1 : 25 000 generalised maps (TK25 map sheets) were utilised to compile the 1 : 200 000 (GÜK 200) generalised maps and are already almost completely generalised for the GÜK 200 target scale. Map compilation was fairly quick (generally a few weeks to months), leading a rather low spatial resolution. The edges of the individual GK25s are not generally matched to the neighbouring sheets. The result can be what are referred to as sheet edge dislocations. The main reasons for this are the different times at which the individual geological maps were compiled (e.g. one sheet in 1929, the neighbouring sheet not until 1985) and that detailed and generalised mapping were performed on adjacent sheet areas, so that matching the sheet edges is not possible due to the different compilation detail. It is currently not possible to revise all geological maps at this scale.NIBIS-MetadatenopendataGeologygeoscientificInformationinfoMapAccessServiceLandesamt für Bergbau, Energie und Geologie (LBEG)postal
