  • The International Map of the Iron Ore Deposits of Europe 1 : 2.500.000 completed in 1977 is published by the Federal Institute for Geosciences and Natural Resources (BGR) About 70 geoscientists from Europe, North Africa, Eastern Europe and Middle East collaborated with the Editorial Staff in the compilation of the map and the Editorial Notes. More than 800 iron ore deposits are represented on the map which covers 42 countries in 16 map sheets. All deposits of importance, either actually being mined or recently abandoned, are included. Deposits of only genetic or historic interest are also shown. Detailed information on the Map of Iron Ore Deposits of Europe - to its structure, arrangement and background data - can be found in the Explanatory Notes to the Map

  • The International Hydrogeological Map of Europe, scale 1:1,500,000 is a series of general hydrogeological maps comprising 25 map sheets with explanatory notes, covering the whole European continent and parts of the Near East. The national contributions to this map series were compiled by hydrogeologists and experts in related sciences of the countries concerned under the auspices of the International Association of Hydrogeologists (IAH) and its Commission on Hydrogeological Maps (COHYM). The project is supported by the Commission for the Geological Map of the World (CGMW).The scientific editorial work is supported financially by the Government of the Federal Republic of Germany through the Bundesanstalt für Geowissenschaften und Rohstoffe (BGR) and by the United Nations Educational, Scientific and Cultural Organization (UNESCO). These organizations are responsible for the cartography, printing and publication of the map sheets and explanatory notes.The series of hydrogeological maps seeks to represent the hydrogeological setting of Europe as a whole without regard to political boundaries. Together with the information presented in the accompanying explanatory notes, the map can be used for scientific purposes, for large-scale regional planning and as a basis for detailed hydrogeological mapping.

  • The International Geological Map of Europe and the Mediteranean Regions 1 : 1 500 000 ("Carte Géologique Internationale de l'Europe et des Régions Méditerranéennes 1 : 1 500 000") shows the geology of the European continent from the Ural mountains in the east up to Island in the west and the whole mediteranean region in the south. The geology is differenciated in stratigraphy, igneous and metamorphic rocks. In addition there are two legend sheets and a title sheet. The language of the series is French.

  • The Land use-stratified soil map of Germany 1:1,000,000 (BUEK1000N), Version 2.31, part forest soils, was subdivided according to the main land cover types (forest, cropland and grassland) using the 1990 CORINE Land Cover data. However, it cannot be expected that the legend of this soil map is valid for the CORINE areas (in this project processed as vector data with the resolution of ca. 0,25 km2) rather than for larger patches (ca. 4 km2). Thus, the land cover data had to be generalized. The original land-cover classes were first aggregated into 14 combined classes, then generalized to at least 4 km2 patches, and finally intersected with the soil map units. The unchanged original soil map units were thus geometrically subdivided by land cover. Soil regions, soil landscapes and European climatic zones were also considered in order to stratify the legend of this new digital database. In another working step, the descriptions of the soil legend units were re-written in order to distinguish and to describe typical soil types and soil profiles under forest, cropland and grassland. For that, data from the BGR soil profile data base and from higher resolution soil maps as well as soil profiles from the national forest soil condition monitoring were evaluated. The results are stored in a relational database which is part of the BGR soil information system “FISBo BGR”. An additional, 54-page booklet with explanations for BUEK1000N can be purchased at the GeoCenter Touristik Medien Service GmbH in D-70565 Stuttgart.

  • The idea to represent the main features of the European Quaternary was first discussed at the Second Congress of the International Union for Quaternary Research (INQUA) held in Leningrad (St. Petersburg) in 1932. Compiled by the Federal Institute for Geosciences and Natural Resources (BGR) in cooperation with the INQUA, the International Quaternary Map of Europe 1 : 2.500.000 was finished in 1995. It is jointly published by the BGR and UNESCO. Several Quaternary features such as end moraines, ground moraine hillocks, kames, drumlins, eskers and ice border lines are represented on the map. Additionally, the map shows the directions of ice movements, limits of marine transgressions and tectonic faults. Important localities of Quaternary discovery relating to both geology and prehistory, bathymetric lines and recent deposits covering the sea floor are also indicated as well. The legend on each of the 14 map sheets is in German and, depending on the territories covered, in English, French or Russian. The general legend is placed on map sheet number 15.

  • The map shows spatial units of Germany that can be uniformly described and delimited with respect to the type of flow as well as the chemical composition of the groundwater. In total, a distinction is made between five regions and 24 subregions, which have been assigned to the most important landscape units in Germany. For each subregion, a schematic lithological column profile has been compiled, showing a typical layered structure of the subsurface of each region. The types of rock are additionally subdivided into aquifers, aquitards and aquicludes. The aquifers are classified into the three classes of pore, fractured and karst aquifers, while the aquitards are divided into unconsolidated or consolidated rocks. Another distinction is made according to the prevailing chemical environment of the rock (silicate, carbonate, sulphate, organic). As a result, ten types of aquifers and six types of aquitards are distinguished. The basis for the map is the digital data of the Geological Map of Germany 1:1,000,000 (GK1000).

  • In the map, all strata are first classified in the four main types “pore aquifers”, “combined pore and fractured aquifers”, “fractured and karst aquifers” and “aquitards and aquicludes”. Further differentiation is made depending on the areal extent and productivity of the aquifers according to the classification of the Standard Legend for Hydrogeological Maps (SLHyM). The productivity classes have been derived from permeability values. In addition, the surface strata are divided into 19 different types of consolidated or unconsolidated rocks and four types of covering layers. Furthermore, the map shows salinity zones of near-surface groundwater in inland areas, as well as zones of saltwater intrusions along the coast. Areas in which groundwater is affected by mining are also shown. The map “Hydrogeology” is based on the digital Geological Map of Germany 1:1,000,000 (GK1000) published by BGR in 1993. The digital GK1000 contains attributes for the stratigraphy, lithology and genesis of the rocks.

  • The map shows the representative chemical content of groundwater for 22 hydrogeological subregions of Germany. The classification of each sub-region was based on the TDS value (total dissolved solids) and the chemical inventory. According to the degree of mineralization, five classes of waters were distinguished (very small, low, medium, high and strongly changing solution contents). The classification of the waters by their chemical inventory was made according to the equivalent percentage of the main cations and anions based on the Piper quadruple diagram. With this chemical classification and the degree of mineralization, 22 geogenic groundwater types could be differentiated throughout Germany. The basis for the mapping of geogenic groundwater quality is the "Hydrogeological Regions" map. The water quality data comes from the groundwater monitoring networks of the German federal states, which were collected by the State Geological Surveys or the State Environmental Surveys. Further analyses are based on the data of the former Central Geological Institute (ZGI) of the GDR. In total, sample data of nearly 8,000 observation wells have been evaluated.

  • The series 'Geoscience Map of Germany 1: 2 000 000' contains easily comprehensible maps on various topics. The base map "Geology" shows Germany and the adjacent areas in 30 units, differentiated by the formation age. In addition, areas with igneous and metamorphic (formed by shaping) rocks are reported. 5 different types of lines provide an overview of fracture zones in the subsurface. In addition, the expansions of the last ice age are included. A schematic cross section through the surface from south to north shows the structure of the older basement and its cover by younger rocks. It is available in two versions: one with a simple topography and once, for better orientation, with the network of interstate highways. The map 'Important deposits' shows deposits and mines of energy raw materials, metal materials, industrial minerals and salts based on a simplified, time-structured geology within Germany.
