    Description: Abstract
    Description: The 50 km long profile 1B was recorded in 1987 as part of the joint reflection venture DEKORP 1 of DEKORP (German Deep Seismic Reflection Program) and BELCORP (Belgian Continental Reflection Seismic Program) groups. It was surveyed to investigate the deep crustal structure of the western Rhenish Massif with high-fold near-vertical incidence vibroseis acquisition. The objectives of the experiment were to analyse deep Variscan and post-Variscan crustal structures in the region and to compare them with the results from the eastern Rhenish Massif gathered from the survey DEKORP 2N. The first results were presented by DEKORP Research Group (1990, 1991) and supplemented by many other researches. The Technical Report of line 1B gives detailed information about acquisition and processing parameters. The European Variscides, extending from the French Central Massif to the East European Platform, originated during the collision between Gondwana and Baltica in the Late Palaeozoic. Due to involvement of various crustal blocks in the orogenesis, the mountain belt is subdivided into distinct zones. The external fold-and-thrust belts of the Rhenohercynian and Saxothuringian as well as the predominantly crystalline body of the Moldanubian dominate the central European segment of the Variscides. Polyphase tectonic deformation, magmatism and metamorphic processes led to a complex interlinking between the units. The Rhenohercynian Zone is a foreland fold-and-thrust belt cropping out in the Rhenish Massif which extends from the Ardennes to the Harz Mountains. This geological unit consists predominantly of Devonian and Lower Carboniferous rocks affected by very low-grade metamorphism (DEKORP Research Group, 1991). The survey 1B was carried out in the western part of the Rhenish Massif and trends nearly N-S starting in the western volcanic zone of the Eifel, the Tertiary Hoch Eifel Volcanic Field represented by alkali basalts and fractionated volcanics. The line also runs over a positiv magnetic anomaly, the Kelberg Magnetic High which is located on the southern flank of the East Eifel Main Anticline. Afterwards, 1B crosses the SE-dipping Siegen Main Thrust and ends in the Mosel Syncline, the northern border of the Hunsrueck Mountains (DEKORP Research Group, 1991). The profile joins line 1A in the north and continues to the southeast with line 1C.

    Description: The German Continental Seismic Reflection Program DEKORP (DEutsches KOntinentales Reflexionsseismisches Programm) was carried out between 1984 – 1999 as the German national reflection seismic program funded by the Federal Ministry of Research and Technology (BMFT), Bonn [now: the Federal Ministry of Education and Research (BMBF)]. DEKORP was administrated by the former Geological Survey of Lower Saxony (NLfB), Hannover [now: the State Authority for Mining, Energy and Geology (LBEG)]. In 1994 the DEKORP management was taken over by the Helmholtz Centre Potsdam GFZ German Research Centre for Geosciences. The aim of DEKORP was to investigate the deep crustal structure of Germany with high-resolution near-vertical incidence (mostly vibro)seismic acquisition, supplemented by wide-angle seismic and other target-oriented piggy-back experiments, all complemented by optimized methods of data processing and interpretation. The DEKORP project was closely linked with the KTB (German continental deep-drilling program) and was an equivalent to many other deep-seismic programs world-wide such as COCORP, BIRPS, LITHOPROBE, ECORS, CROP, BELCORP, IBERSEIS and many more. The DEKORP-Atlas (Meissner & Bortfeld, 1990) gives a detailed overview about most of the different campaigns and results. In sum, the resulting DEKORP database includes approximately 40 crustal-scale 2D-seismic reflection lines covering a total of ca. 4 700 km and one 3D-seismic reflection survey covering ca. 400 km². Each DEKORP survey is provided with all datasets that are necessary for either a re-processing (i.e. raw unstacked field records in SEGY) or a re-interpretation (i.e. finally processed sections in SEGY or PNG). The raw data are sorted by records or by CDPs. The final data are available as unmigrated or migrated stacks without or with coherency enhancement. Automatical line-drawings are also included. All data come with additional meta information for each domain (source, receiver, CDP) like coordinates, elevations, locations and static corrections combined in ASCII-tables for geometry assignment. Furthermore, all metadata originating from paper copies are made available as scanned files in PNG or PDF, e.g. field and observer reports, location maps in different scales, near-surface profile headers and others. The DEKORP datasets provide unique and deep insights into the subsurface below Germany covering the earth’s crust from the surface to the upper mantle and are increasingly requested by academic institutions and commercial companies. Fields of applications are geothermal development, hazard analysis, hydrocarbon/shale gas exploration, underground gas storage, tunnel construction and much more.

    Description: Abstract
    Description: The ca. 163 km long KTB Line 1 was recorded in 1984 as part of the DEKORP, the German Continental Seismic Reflection Program, in the context of presite investigations for the KTB, the German Continental Deep Drilling Project. KTB 8401 is one of the four KTB seismic reflection lines, which were performed in the Black Forest, one of the candidates for the KTB drilling site. The purpose of the investigations was to reveal a strongly differentiated crust beneath the Black Forest with high-fold near-vertical incidence vibroseis acquisition. The main focus was on the crustal structure of the Black Forest massif with respect to the role and extent of Variscan thrust and extension tectonics and the geometry of deep crustal reflection patterns. Details of the experiment, first results and interpretations were published by Lüschen et al. (1987) and KTB-Research Group Black Forest (1987). Results discussed together with the KTB surveys in the Upper Palatinate were presented in a number of works which can be found in Emmermann & Wohlenberg (1989). The Technical Report of KTB 8401 gives complete information about acquisition and processing parameters. The European Variscides, extending from the French Central Massif to the East European Platform, originated during the collision between Gondwana and Baltica in the Late Palaeozoic. Due to involvement of various crustal blocks in the orogenesis, the mountain belt is subdivided into distinct zones. The external fold-and-thrust belts of the Rhenohercynian and Saxothuringian as well as the predominantly crystalline body of the Moldanubian dominate the central European segment of the Variscides. Polyphase tectonic deformation, magmatism and metamorphic processes led to a complex interlinking between the units. The Black Forest is the uplifted eastern shoulder of the Upper Rhine Graben within the internal Moldanubian zone, where rocks of the Variscan basement complex of Central Europe are exposed. The crystalline basement of the Black Forest consists of high-grade gneisses and migmatites intruded by Variscan granites. It was uplifted during the Tertiary rift movements of the Rhine Graben. The NS running profile 8401 follows the morphological axis of the Black Forest across the Central Black Forest Gneiss Complex and the adjacent Variscan thrust zones: the southward-dipping Saxothuringian-Moldanubian suture zone in the north and the NW-dipping Badenweiler-Lenzkirch crustal thrust zone in the south. In the west and the east the Central Gneiss Complex is bounded by the Tertiary Thinegraben and gently eastward-dipping Mesozoic sediments respectively. The central part of the Gneiss Complex is covered by two intersecting profiles generating a triangle of 3-4 km side length together with line 8401. Farther to the south KTB 8401 is crossed by line KTB 8514.

The NW-SE trending KTB 8514 was recorded in order to investigate the northward-dipping Paleozoic Badenweiler-Lenzkirch thrust zone and its implications for the proposed drill site near Haslach (Lüschen et al. 1987). The thrust zone separates two crystalline blocks, the Central Black Forest Gneiss Complex and the Southern Black Forest Complex, which differ significantly both in their petrological and geophysical characteristics (Lüschen et al., 1987). KTB 8514 crosses the nearly S-N running KTB 8401, which follows the morphological axis of the Black Forest and intersects the Central Black Forest Gneiss Complex.

    Description: Abstract
    Description: The profile DEKORP 3B/MVE, consisting of the two segments West and East, was recorded in 1990 as part of the DEKORP project, the German deep seismic reflection program. The focus of the DEKORP project was on deep crustal and lithospheric structures and therefore originally not on structures at shallower depths. From today's perspective, however, this depth range is of great interest for a wide range of possible technical applications (including medium-depth and deep geothermal projects). The original data is published by Stiller et al. (2021). The westernmost 91 km of the 208 km long profile 3B (West) were reprocessed on behalf of the Hessian Agency of Nature Conservation, Environment and Geology (HLNUG). As a particularity, also a set of 18 cross-lines, each ca. 12 km in length and perpendicular to the main lines, were surveyed along DEKORP 3B/MVE to get information about possible cross-dips. Four of those short cross-lines were reprocessed in 2D as well. The focus of the reprocessing of the old data was on improving the resolution / mapping of geological structures down to a depth of 6 km (approx. 3 s TWT) to describe the prolongation of faults and geological structures in more detail than in previous studies. In order to achieve these goals and in view of the fact that today's processing and evaluation methods have been improved considerably compared to the 1990‘s, a state-of-the-art reprocessing was implemented. In comparison with the original processing (Stiller et al. (2021)), more sophisticated processing steps like CRS (Common Reflection Surface) instead of CDP (Common Depth Point) stacking, turning-ray tomography and prestack time and depth migration were carried out. The reprocessing results of the DEKORP 3B (West) survey comprise all datasets newly achieved in addition to the datasets from the original processing (Stiller et al. (2021)), i.e. (1) the migrated CRS image gathers as unstacked data, and (2) the pure CRS stack, the poststack-time as well as prestack-time and prestack-depth migrated sections as stacked data. Moreover, (3) all velocity models used for the different versions including (4) the separate first-break tomography inversion, are contained. Additionally, the results of the 2D-reprocessing of cross-lines Q21-Q24 are included. All reprocessed data come in SEGY trace format, the final sections additionally in PDF graphic format. A reprocessing report is included as well as again all meta information for each domain (source, receiver, CDP) like coordinates, elevations, locations and static corrections combined in ASCII-tables for geometry assignment purposes. The DEKORP 3 survey was a combined seismic survey investigating the Variscan structures of the Rhenohercynian and the Saxothuringian. Consisting of three seismic lines it starts in the Rhenohercynian Hessian Depression (DEKORP 3A), crosses the Saxothuringian Mid-German Crystalline High (DEKORP 3B/MVE (West)) and runs parallel to the northern margin of the Moldanubian (DEKORP 3B/MVE (East)). The 207.65 km long DEKORP 3B (West) profile trends NW-SE and intersects DEKORP 3A in the Tertiary volcanic field within the "Northern Phyllite Zone". It crosses the Hessian Depression of the Rhenohercynian, runs through the Rhön Tertiary volcanic province and the Mesozoic Franconian Basin to the Bohemian Massif. The line ends at the Franconian Line. The reprocessed datasets contain a sub-section of the entire 3B (West) profile with a total length of 90.8 km of full CDP coverage, covering the territory of the state of Hesse, i. e. from the profile’s starting point in the NW to the SE until the Rhön volcanic complex. The reprocessed part of 3B (West) is intersected by four short cross-lines along the profile at km 8.75, 32.6, 64.75, 84.35 and by DEKORP 3A at km 42.3. The DEKORP '90-3B profile is of particular interest to investigate the seismic resolution of the Hessian depression, the east-hessian Buntsandstein nappe as well as the tertiary volcanic fields of the Kellerwald and Rhön.

    Description: The German Continental Seismic Reflection Program DEKORP (DEutsches KOntinentales Reflexionsseismisches Programm) was carried out between 1984 - 1997 and funded by the Federal Ministry of Education, Science and Technology (BMFT), now Federal Ministry of Education and Science (BMBF). The data was originally processed in the DEKORP Processing Centre (DPC) at the Institute of Geophysics of the Technical University Clausthal. DEKORP was founded in 1983 with the aim to investigate the deep crustal structure of Germany with high-resolution near-vertical incidence seismic methods. It was closely associated with the deep drilling project KTB (German continental deep-drilling program). One of the main research topics of DEKORP were deep seismic studies to investigate the lithospheric structure beneath Germany. The DEKORP profiles cover approx. 450 km in the state of Hesse and mostly cross areas for which there is only insufficient geological data (i.e. only few deep boreholes). As a governmental agency the HLNUG archives and publishes the data for future applications and usages, such as the search for a repository for nuclear waste in Germany, an expansion of the geophysical database, possibilities for modelling using gravimetric and magnetic data as well as an improvement of the 3D underground model of the state of Hesse. Therefore, the results are directly linked to the new geological 3D model of the state of Hesse, developed by the Technical University of Darmstadt (Hessen3D 2.0 project, BMWi-FKZ: 0325944). The reprocessed DEKORP datasets provide up-to-date unique and deep insights into the subsurface below Germany covering the earth’s crust from the surface to the upper mantle. Fields of applications are geothermal development, hazard analysis, hydrocarbon/shale gas exploration, underground gas storage, tunnel construction and much more.

    Description: Abstract
    Description: The profile 2S was recorded in 1984 as part of the DEKORP project, the German deep seismic reflection program. The focus of the DEKORP project was on deep crustal and lithospheric structures and therefore originally not on structures at shallower depths. From today's perspective, however, this depth range is of great interest for a wide range of possible technical applications (including medium-depth and deep geothermal projects). The original data is published by Stiller et al. (2020). The northernmost 50 km of the 250 km long profile 2S were reprocessed on behalf of the Hessian Agency of Nature Conservation, Environment and Geology (HLNUG). The focus of the reprocessing was on improving the resolution / mapping of geological structures down to a depth of 6 km (approx. 3 s TWT) to describe the prolongation of faults and geological structures in more detail than in previous studies. In order to achieve these goals and in view of the fact that today's processing and evaluation methods have been improved considerably compared to the 1990‘s, a state-of-the-art reprocessing was implemented. In comparison with the original processing (Stiller et al. (2020)), more sophisticated processing steps like CRS (Common Reflection Surface) instead of CDP (Common Depth Point) stacking, turning-ray tomography and prestack time and depth migration were carried out. The reprocessing results of the DEKORP 2S survey comprise all datasets newly achieved in addition to the datasets from the original processing (Stiller et al. (2020)), i.e. (1) the migrated CRS image gathers as unstacked data, and (2) the pure CRS stack, the poststack-time as well as prestack-time and prestack-depth migrated sections as stacked data. Moreover, (3) all velocity models used for the different versions including (4) the separate first-break tomography inversion, are contained. All reprocessed data come in SEGY trace format, the final sections additionally in PDF graphic format. A reprocessing report is included as well as again all meta information for each domain (source, receiver, CDP) like coordinates, elevations, locations and static corrections combined in ASCII-tables for geometry assignment purposes. The DEKORP 2 survey, consisting of the three segments 86-2Q, 86-2N and 84-2S, starts in the sub-Variscan foredeep of the Münsterland Basin and ends in the Moldanubian region at the Danube. The central part crosses the Rhenish Massif (Rhenohercynian), the Spessart Mountains of the Mid-German Crystalline High (Saxothuringian) and the meteorite impact location of the "Nördlinger Ries". DEKORP '84-2S, was the first DEKORP line and the only one which mainly used explosives as the seismic source. The 250 km long, SE-NW striking profile extends from the Rhenohercynian Taunus Mountains to the Danube thereby crossing the Spessart Mountains, the Hessian Trough and the "Nördlinger Ries". The profile DEKORP 2S is the southern continuation of DEKORP 2N, which intersects at profile km 246.08. The reprocessed datasets contain a sub-section of the entire 2S profile with a total length of 50 km of full CDP fold, covering the profile’s northern part through the state of Hesse. The DEKORP '84-2S profile is of particular interest to investigate the seismic resolution of the Rhenohercynian Taunus Mountains including the Taunus ridge, as well as the Tertiary Hessian Trough, the Permian Wetterau nappe and a small part of the crystalline Spessart Mountains. The seismic sections of 2S show clearly visible, predominantly SE-dipping reflectors indicating flat-and-ramp tectonics and a differentiation into a highly reflective lower crust and a less reflective upper crust. Due to the use of explosive shots with relatively large spacing as the seismic source, less new information could be achieved for the uppermost crust compared to the original processing and to other DEKORP (vibroseis) surveys. A clear Moho reflection is visible throughout the whole profile section at a depth of ca. 26 to 28 km.

The 219 km long, SSE-NNW striking DEKORP 2N line provides a cross-section through the Rhenish Massif from the sub-Variscan Münsterland Basin in the north to the Rhenohercynian Taunus Mountains in the south. The profile is the northern continuation of DEKORP 2S, which intersects at profile km 7.72. The reprocessed datasets contain a sub-section of the entire 2N with a total length of 67.84 km of full CDP fold, covering the profile’s southern part through the state of Hesse. The DEKORP '86-2N profile is of particular interest to investigate the seismic resolution of the Rhenish Massif and its different structures, such as the Siegen anticline, the Dill syncline, and the Lahn anticline. In the most southern part, the profile reaches into the Rhenohercynian Taunus Mountains until the Taunus ridge. The seismic sections of 2N show clear, deep reaching reflections along the prolongation of the whole profile supporting newer theories of nappe structures in the hessian part of the Rhenish Massif. The reflections are more clearly visible than in the original processing. All visible structures are mainly SE-dipping reflections in the upper crust, which represent lithologic contrasts as well as thrust faults known from surface geology. In the lower crust highly reflective predominantly SE-dipping reflectors can be identified. Moho reflections are clearly identifiable and deepening to the NW.

    Description: The profile 3A was recorded in 1990 as part of the DEKORP project, the German deep seismic reflection program. The focus of the DEKORP project was on deep crustal and lithospheric structures and therefore originally not on structures at shallower depths. From today's perspective, however, this depth range is of great interest for a wide range of possible technical applications (including medium-depth and deep geothermal projects). The original data is published by Stiller et al. (2021). On behalf of the Hessian Agency of Nature Conservation, Environment and Geology (HLNUG). From the 128 km long profile 3A the southernmost 104 km (plus additional 9 km northwards with decreasing CDP coverage to avoid boundary effects during migration) were reprocessed. As a particularity, also a set of 6 cross-lines, each ca. 9.6 km in length and perpendicular to the main line, were surveyed along DEKORP 3A to get information about possible cross-dips. Five of those short cross-lines (Q12-Q16) were reprocessed in 2D and 3D as well.

Detailed information about acquisition and reprocessing parameters can be found in the accompanying Technical Report (Stiller & Agafonova, 2022). The DEKORP 3 survey was a combined seismic survey investigating the Variscan structures of the Rhenohercynian and the Saxothuringian. Consisting of three seismic lines it starts in the Rhenohercynian Hessian Depression (DEKORP 3A), crosses the Saxothuringian Mid-German Crystalline High (DEKORP 3B/MVE (West)) and runs parallel to the northern margin of the Moldanubian (DEKORP 3B/MVE (East)). The 128 km long DEKORP 3A profile runs N-S within the Hessian Depression from the Solling Dome in the Rhenohercynian to the Vogelsberg Volcano of the Saxothuringian Mid-German Crystalline High. The middle part of the profile crosses the "Northern Phyllite Zone". The reprocessed datasets contain a sub-section of the entire profile with a total length of 104.1 km of full CDP coverage, covering the territory of the state of Hesse. The reprocessed part of 3A is intersected by five short cross-lines along the profile at km 31.75, 53.55, 73.75, 89.85, 109.85 and by DEKORP 3B/MVE (West) at km 120.75 at its southern end. The DEKORP '90-3A profile is of particular interest to investigate the seismic resolution of the crust beneath the Permo-Mesozoic to Tertiary Hessian depression, the Kassel graben structure, as well as the tertiary volcanic fields of the Reinhardswald, Habichtswald, Knüll, Söhrewald and stopping just north of the large Cenozoic Vogelsberg complex.

    Deep seismic reflection profile DEKORP 1985-4Q across the Bavarian Forest, Southeast Germany (2021)
    GFZ Data Services
    Details
    Publication Date: 2022-05-13
    Description: Abstract
    Description: The 36 km long line 4Q was recorded in 1985 as part of the DEKORP project, the German continental seismic reflection program. The aim of the survey was to explore important tectonic structures through the regional tectonic trend of the Bavarian Forest (NW-SE) with high-fold near-vertical incidence vibroseis acquisition. Details of the experiment, first results and interpretations were published by DEKORP Research Group (1987, 1988). The Technical Report of line 4Q gives complete information about acquisition and processing parameters. The European Variscides, extending from the French Central Massif to the East European Platform, originated during the collision between Gondwana and Baltica in the Late Palaeozoic. Due to involvement of various crustal blocks in the orogenesis, the mountain belt is subdivided into distinct zones. The external fold-and-thrust belts of the Rhenohercynian and Saxothuringian as well as the predominantly crystalline body of the Moldanubian dominate the central European segment of the Variscides. Polyphase tectonic deformation, magmatism and metamorphic processes led to a complex interlinking between the units. The Moldanubian unit contains blocks of pre-Variscan crust and their Palaezoic cover. During the Variscan orogeny the Moldanubian crust was thrust towards the NW over the Saxothuringian foreland. Both units were welded together by a low-pressure metamorphism accompanied by polyphase deformation (DEKORP Research Group, 1987, 1988). The SW-NE striking line 4Q runs perpendicular to the gneisses of the Bavarian Forest at the southwestern margin of the Bohemian Massif, a part of the Moldanubian Zone. In the southwest the profile crosses the NW-SE striking Bavarian Pfahl. The 150 km long quartz vein is a dextral shear zone with cataclastic as well as ductile deformation and extensive quartz mineralization (DEKORP Research Group, 1988). In the northeast DEKORP 4Q intersects the Hoher Bogen, an amphibolitic nappe, belonging to the western margin of the Tepla-Taus-Complex which is marked by an important volume of mafic metamorphic rocks (DEKORP Research Group, 1988). The profile 4Q traverses DEKORP 4N at its northeastern end almost perpendicularly.

    Description: The German Continental Seismic Reflection Program DEKORP (DEutsches KOntinentales Reflexionsseismisches Programm) was carried out between 1984 – 1999 as the German national reflection seismic program funded by the Federal Ministry of Research and Technology (BMFT), Bonn (now: Federal Ministry of Education and Research BMBF). DEKORP was administrated by the former Geological Survey of Lower Saxony (NLfB), Hanover (now: State Authority for Mining, Energy and Geology LBEG). In 1994 the DEKORP management was taken over by the Helmholtz Centre Potsdam GFZ German Research Centre for Geosciences. The aim of DEKORP was to investigate the deep crustal structure of Germany with high-resolution near-vertical incidence (mostly vibro)seismic acquisition, supplemented by wide-angle seismic and other target-oriented piggy-back experiments, all complemented by optimized methods of data processing and interpretation. The DEKORP project was closely linked with the KTB (German continental deep-drilling program) and was an equivalent to many other deep-seismic programs world-wide such as COCORP, BIRPS, LITHOPROBE, ECORS, CROP, BELCORP, IBERSEIS and many more. The DEKORP-Atlas (Meissner & Bortfeld, 1990) gives a detailed overview about most of the different campaigns and results. In sum, the resulting DEKORP database includes approximately 40 crustal-scale 2D-seismic reflection lines covering a total of ca. 4 700 km and one 3D-seismic reflection survey covering ca. 400 km². Each DEKORP survey is provided with all datasets that are necessary for either a re-processing (i.e. raw unstacked field records in SEGY) or a re-interpretation (i.e. finally processed sections in SEGY or PNG). The raw data are sorted by records or by CDPs. The final data are available as unmigrated or migrated stacks without or with coherency enhancement. Automatically line-drawings are also included. All data come with additional meta information for each domain (source, receiver, CDP) like coordinates, elevations, locations and static corrections combined in ASCII-tables for geometry assignment. Furthermore, all metadata originating from paper copies are made available as scanned files in PNG or PDF, e.g. field and observer reports, location maps in different scales, near-surface profile headers and others.
