The 55 km long KTB Line 5 was recorded in 1985 as part of deep seismic reflection investigations for the DEKORP (German Continental Seismic Reflection Program) and KTB (German Continental Deep Drilling Program) projects. The network of lines consists of two DEKORP profiles, DEKORP 4N and its appendix 4Q, and six shorter KTB profiles, KTB 8501 – 8506, arranged in the form of a grid parallel and perpendicular to the main tectonic lineaments. The purpose of the investigations was to explore the planned target area for the Continental Deep Drilling Site in the Upper Palatinate with high-fold near-vertical incidence vibroseis acquisition. The main focus was on the crustal structure of the central Mid-European Variscides down to the Moho and the uppermost mantle and, in particular, on the suture between the Moldanubian Zone and the northward adjacent Saxothuringian Zone as well as on the metamorphic Zone of Erbendorf-Vohenstrauss. The array of the KTB profiles represents the pre-cursor of the 3-D seismic survey ISO 1989 (Integrated Seismics Oberpfalz). Details of the experiment, first results and interpretations were published by DEKORP Research Group (1987, 1988). Results discussed together with the drilling site were presented in a number of works which can be found in Emmermann & Wohlenberg (1989). The Technical Report of KTB 8505 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 Saxothuringian represents the infill of a Cambro-Ordovician basin. The Moldanubian contains blocks of pre-Variscan crust and their Palaezoic cover. During the Variscan orogeny the Moldanubian crust was thrust toward the northwest over the Saxothuringian foreland. Both units were welded to one another by a low-pressure metamorphism accompanied by polyphase deformation (DEKORP Research Group, 1987, 1988). The SSE-NNW trending line KTB 8505 runs from the Upper Palatinate Forest in the southeast to the Fichtel Mountains in the northwest. The line is located ca. 9 km northeast from the KTB drill site, nearly parallel to KTB 8504, KTB 8506 and DEKORP 4N and perpendicular to KTB 8501 – 8503. The profile also crosses the DEKORP 3D survey ISO 1989. KTB 8505 was arranged to explore the Tirschenreuth-Mähring segment of the Saxothuringian/Moldanubian boundary region (DEKORP Research Group, 1988).
GEMAS (Geochemical Mapping of Agricultural and Grazing Land Soil in Europe) ist ein Kooperationsprojekt zwischen der Expertengruppe „Geochemie“ der europäischen geologischen Dienste (EuroGeoSurveys) und Eurometeaux (Verbund der europäischen Metallindustrie). Insgesamt waren an der Durchführung des Projektes weltweit über 60 internationale Organisationen und Institutionen beteiligt. In den Jahren 2008 und 2009 wurden in 33 europäischen Ländern auf einer Fläche von 5 600 000 km² insgesamt 2219 Ackerproben (Ackerlandböden, 0 – 20 cm, Ap-Proben) und 2127 Grünlandproben (Weidelandböden, 0 – 10 cm, Gr-Proben) entnommen. In den Proben wurden 52 Elemente im Königswasseraufschluss, 41 Elemente als Gesamtgehalte sowie TC und TOC bestimmt. Ergänzend wurde in den Ap-Proben zusätzlich 57 Elemente in der mobilen Metallionenfraktion (MMI®) sowie die Bleiisotopenverhältnisse untersucht. Alle analytischen Untersuchungen unterlagen einer strengen externen Qualitätssicherung. Damit liegt erstmals ein qualitätsgesicherter und harmonisierter geochemischer Datensatz für die europäischen Landwirtschaftsböden mit einer Belegungsdichte von einer Probe pro 2 500 km² vor, der eine Darstellung der Elementgehalte und deren Bioverfügbarkeit im kontinentalen (europäischen) Maßstab ermöglicht. Die Downloaddateien zeigen die flächenhafte Verteilung der mit verschiedenen Analysenmetoden bestimmten Elementgehalte in Form von farbigen Isoflächenkarten mit jeweils 7 und 72 Klassen.
The 56 km long KTB Line 3 was recorded in 1985 as part of deep seismic reflection investigations for the DEKORP (German Continental Seismic Reflection Program) and KTB (German Continental Deep Drilling Program) projects. The network of lines consists of two DEKORP profiles, DEKORP 4N and its appendix 4Q, and six shorter KTB profiles, KTB 8501 – 8506, arranged in the form of a grid parallel and perpendicular to the main tectonic lineaments.

Details of the experiment, first results and interpretations were published by DEKORP Research Group (1987, 1988). Results discussed together with the drilling site were presented in a number of works which can be found in Emmermann & Wohlenberg (1989). The Technical Report of KTB 8503 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.

Both units were welded to one another by a low-pressure metamorphism accompanied by polyphase deformation (DEKORP Research Group, 1987, 1988). The WSW – ENE striking line KTB 8503 is located normally to the KTB lines 8504, 8505 and 8506 and to DEKORP 4N running ca. 16 km south of the KTB drill hole. As well as the lines KTB 8501 and 8502 the profile 8503 was arranged parallel to strike running across the NW-SE directed system of block-faults at the southwestern margin of the Bohemian Massif (DEKORP Research Group, 1988). In the southwest KTB 8503 crosses the Franconian Line, a fault zone which separates the crystalline Bohemian Massif from a foreland. Farther to the northeast KTB 8503 runs through metamorphic nappes and Variscan granites of the Erbendorf-Vohenstrauss-Zone.
The 187 km long line 4N was recorded in 1985 as part of the DEKORP project, the German continental seismic reflection program, and served as a basis for a network of six seismic reflection lines KTB 8501 – 8506, which were performed to investigate the planned target area for the Continental Deep Drilling Program (KTB) in the Upper Palatinate. The aim of the survey 4N was to explore the crustal structure of the central Mid-European Variscides down to the Moho and the uppermost mantle with high-fold near-vertical incidence vibroseis acquisition and, in particular, to scan the suture between the Moldanubian Zone and the northward adjacent Saxothuringian Zone. Details of the experiment, first results and interpretations were published by DEKORP Research Group (1987, 1988). The Technical Report of line 4N gives complete information about acquisition and processing parameters.

Both units were welded together by a low-pressure metamorphism accompanied by polyphase deformation (DEKORP Research Group, 1987, 1988). The SE-NW striking line 4N runs along the western border of the Bohemian Massif perpendicular to the main tectonic trend (SW-NE). The profile starts in the Bavarian Forest and runs across the Upper Palatinate Forest. Shortly before the NE-trending Erbendorf Line, which separates the Moldanubian unit from the Saxothuringian unit, the profile runs through the area of the KTB drill site. In the Saxothuringian DEKORP 4N runs through the Fichtel Mountains, the Muenchberg Gneiss Complex and ends in the Franconian Forest. In the Bavarian Forest the line 4N traverses DEKORP 4Q nearly perpendicularly. Farther northwest the profile crosses KTB 8501 – 8503, which were arranged parallel to strike of the orogenic belt, as well as the DEKORP 3-D survey ISO 1989 around the KTB drill hole. In the Muenchberg Gneiss Complex the 4N profile is intersected by DEKORP 3B/MVE (East), which runs along the southern margin of the Saxothuringian belt in a SW-NE direction.
The ca. 62 km long KTB Line 3 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 8403 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).

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 E-W running profile 8403 extends through the Black Forest crystalline basement and the adjacent Triberg Granite Massif onto the Swabian Jura Platform. Near Haslach the profile crosses KTB 8402 and KTB 8401 farther to the east. The intersection of these three lines generates a triangle of 3-4 km side length with a focus on the proposed drilling area. To the west the profile is connected with the DEKORP 9S, which runs across the Rhine Graben and the northern tip of Vosges massif into the Lorraine Basin. To the east KTB 8403 is linked to the Urach profile U1, running through the geothermal anomaly at Urach.
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 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 ca. 43 km long KTB Line 2 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 8402 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 NW-SE running profile 8402 traverses the crystalline basement almost perpendicularly to the Variscan strike. From the northwest to the southeast the line runs across the Central Gneiss Complex and the adjacent Triberg Granite Massif. Near Haslach the profile 8402 crosses KTB 8403 and KTB 8401 farther to the southeast. The intersection of these three lines generates a triangle of 3-4 km side length with a focus on the proposed drilling area.
The 50 km long KTB Line 2 was recorded in 1985 as part of deep seismic reflection investigations for the DEKORP (German Continental Seismic Reflection Program) and KTB (German Continental Deep Drilling Program) projects. The network of lines consists of two DEKORP profiles, DEKORP 4N and its appendix 4Q, and six shorter KTB profiles, KTB 8501 – 8506, arranged in the form of a grid parallel and perpendicular to the main tectonic lineaments.

The ENE – WSW striking line KTB 8502 is located normally to the KTB lines 8504, 8505 and 8506 and to DEKORP 4N. The profile runs close to the area of the KTB drill hole, thereby crossing the DEKORP 3D survey ISO 1989. As well as the lines KTB 8501 and 8503 the profile 8502 was arranged parallel to strike, running across the NW-SE directed system of block-faults at the southwestern margin of the Bohemian Massif (DEKORP Research Group, 1988). In the southwest KTB 8502 crosses the Franconian Line, a fault zone which separates the crystalline Bohemian Massif from a foreland. Farther to the northeast KTB 8502 crosses metamorphic nappes and Variscan granites of the Erbendorf-Vohenstrauss Zone.
