Summarised presentation of the results of the geochemical investigations in Germany in the period 1975 - 1986, Element concentrations in stream waters and stream sediments, Single element maps

Between 1975 and 1986, geochemical investigations were carried out by the Federal Institute for Geosciences and Natural Resources (BGR) on the territory of the then Federal Republic of Germany and by the Central Geological Institute (ZGI) of the former GDR in the area of the pre-Upper Permian bedrock units in the southern part of the former GDR, which lie on the earth's surface or are slightly covered by the Cenozoic. Approximately 98,000 water and 87,500 stream sediment samples were taken and geochemically analysed. The results of these investigations were published in the "Geochemical Atlas of the Federal Republic of Germany" (Fauth et al., 1985) and in the "Final Report on the Comparative Evaluation of the Raw Material Potential in the Bedrock Units of the GDR" (Röllig et al., 1990; in German). The geochemical data collected as part of these investigations, which cover a large part of the area of today's Federal Republic of Germany, are unique in their high sampling density. All subsequent geochemical investigations were carried out with a much lower sample density. These valuable and irretrievable data have been generally accessible via the BGR geoportal since their digital processing and provision in 2022 (Geochemical Atlas of the Federal Republic of Germany) and 2023 (Geochemical Prospection in the bedrock units in the southern part of the former GDR). However, a direct comparison of the maps produced for the two sub-areas is not possible due to the differences in the analytical methods used in the investigations (investigated element spectrum, analytical quality, determination limits, ...). Nevertheless, for some of the investigated elements and parameters it is possible to summarise the results of these geochemical investigations, which are unique in their high occupancy density, with appropriate adjustments (determination limits, representable content ranges, classification of the map legends, ...). Such summarised representations are now being made available for the first time via the BGR geoportal. The downloads show the distribution of the measured element contents and parameters for each element or parameter in four different colored point and isosurface maps.
