  • 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.

  • BGR conducted an airborne survey in the region of Schleiz and Greiz (Thuringia) as part of the BMBF project DESMEX. This is a reconaissance survey with the BGR geophysical standard measuring system. The survey area is located between Gera and Plauen on the edge of the Thuringian Slate mountains on the border to and partly in Saxony. The size of the area is about 445 km². The area was surveyed with 10 flights totalling to 1591 line-km (374.072 survey points). The nominal separation of the 124 NW-SE lines and 8 NE-SW tie lines was 300 m and 2000 m, respectively. The two ASCII datafiles contain the raw data as well as the processed HEM data at the six frequencies of the HEM system (0.4 - 130 kHz).

  • For the individual erosion events, the thicknesses to be eroded were determined from the initial thickness of a sequence. These maps were smoothed again, e.g. in the marginal depressions of the salt diapirs to avoid abrupt thickness transitions. The maps of eroded thicknesses were calculated from the maps of initial thickness of the respective sequence. The initial thickness of a sedimentary layer was determined for the Jurassic and Triassic strata by our own estimates from the missing thicknesses in the area of the salt domes and from calibrated 1D models; for the Carboniferous Stefan and Westfal horizons they were taken from Krull (2005). Initial thickness maps for the Carboniferous sediments were created from the printed maps by scanning, georeferencing, digitizing isolines, and interpolating to a contiguous surface. Maps of eroded thicknesses were then calculated in PetroMod modeling software (Schlumberger, version 2012.2). The amount of erosion is calculated by subtracting the residual thickness (today) from the initial thickness. Since in the hydrocarbon model the salt movement was modeled parallel to the erosion events, it was necessary to correct the calculated erosion amounts or maps finally to avoid horizon overlaps and abrupt cell transitions. For this reason, both sets of maps (initial and eroded thicknesses) are available for download. The maps are available in two different data formats (CPS3 and Zmap). The individual thickness maps have a file size of 8.5 MB each (zip files 0.3 to 1.4 MB).

  • 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.

  • BGR conducted within the project „Airborne geophysical surveys for mapping the shallow subsurface in Germany “ (D-AERO) airborne surveys at the German North Sea coast. The survey area Esens (2008/09) ranges from about Dornum and Aurich in the west to Wittmund and Werdum in the east. The size of the area is about 370 km². The area was surveyed with 23 flights totalling to 1542 line-km (437,562 survey points). The nominal separation of the 75 N-S lines and 8 W-E tie lines was 250 m and 2000 m, respectively. The maps display the geophysical parameters apparent resistivity and centroid depth derived from the HEM data at the six frequencies of the HEM system (0.4 - 130 kHz). Furthermore, horizontal and vertical slices were derived from layered-earth models (resistivities and thicknesses of six model layers).

  • Based on data from geological 3D models of the federal states Baden-Württemberg, Bavaria, Hesse, North Rhine-Westphalia, Rhineland-Palatinate, Saxony, Saxony-Anhalt, and Thuringia, thicknesses of Quaternary and Tertiary sediments were determined. Based on these thickness data, the geological substrate classes "R" (rock), "T" (shallow sediment basins), and "S" (deep sediment basins) were designated according to DIN (National Annex Eurocode 8 - DIN EN 1998-1/Na2023-11: Nationally determined parameters - Eurocode 8: Design of structures for earthquake resistance - Part 1: General rules, seismic actions and rules for buildings). The subsoil, including rocks to a depth of 30 m, was not considered in the designation. The geological substrate classes were represented on a grid with a cell size of 1 km x 1 km. Compared to the previous designation of geological substrate classes, a significantly higher spatial resolution was achieved. For further information on the development of this map, see the final report included.

  • With its Energy Data publication, the Federal Institute for Geosciences and Natural Resources (BGR) presents data and facts on the worldwide availability, production, import and export of energy sources. These include data on fossil and renewable energy sources. In the future, the BGR Energy Study will be published in text and table form every other year. The data tables, on the other hand, will continue to be published annually, and offered for download free of charge. The published data sets on the situation of renewable energy sources including deep geothermal energy and hydrogen, plus energy sources such as crude oil, natural gas, coal, nuclear fuels are a classified and evaluated extract of the BGR energy sources database. In addition to estimating the geological inventory of energy sources with reliable statements on reserves and resources, the energy markets are examined with regard to the global development of production, export, import and consumption. Our Energy Data are meant to advise the Federal Ministry of Economics and Climate Protection (BMWK), German industry and science, and the general public on aspects of natural resource management.

  • 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 Lithofacial Map of the Quaternary 1 : 50,000 (LKQ 50) is a map series of the GDR covering nearly the whole former state territory besides the South of Saxony and Thuringia. The series consists of 123 map sheets, each of which encompassing several horizon maps mostly complemented by about five cross sections. Specifications concerning map content and structure provides Cepek (1999). The data of the LKQ 50 map sheet 1968 Berlin/Nordost provided here were digitised in frame of the Geo3D-Oder project of the German Federal Institute for Geosciences and Natural Resources (BGR). The data include elements of the seven horizon maps 1968-2, 1968-3, 1968-4, 1968-5, 1968-6, 1968-7, and 1968-8. Sheet 1968 Berlin/Nordost was published at an early stage of the map series preparation in 1972. Therefore, the topics of these maps are defined in a primary version 1 of the general legend. In contrast to map sheets of a later publication date the single horizon maps of 1968 Berlin/Nordost lack map legends to provide a specific stratigraphic and genetic classification of the depicted strata. However, as each horizon map comprises just two to four layers, this assignment can be derived from the signatures and the stratigrafic indication of the respective horizon map. For each horizon map the digitised elements comprise several polygon shapefiles of the single layers, a polyline shapefile of isohypses related to layer bases, a point shapefile of lithological profiles and a polygon shapefile of additional information concerning areas of heavy strata deformation and insufficient investigation. Non-numeric contents of the attribute tables are encoded by numbers and are translated in full text by means of key tables. The key table Normalprofil allows the stratigraphic and genetic classification of horizons displayed in horizon maps by code numbers of the column N_ID. Detailed descriptions concerning the data structure are provided in the attachments. Reference: Cepek, A. G.

  • 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.
