Description: The ca. 60 km long seismic line DEKORP 2Q was recorded in 1986 as part of the DEKORP project, the German deep seismic reflection program. The survey was carried out to investigate possible NW-SE trending crustal structure of the Muensterland Basin with high-fold near-vertical incidence vibroseis acquisition. A detailed description of seismic results is provided by Franke et al. (1990) and supplemented by many other researches. The Technical Report of line 2Q 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 W-E directed DEKORP 2Q crosses line 2N nearly perpendicularly and together with its northern part reveals the Upper Cretaceous of the Muensterland Basin, which belongs to the sub-Variscan Foredeep, and the underlying folded Palaeozoic rocks. Towards the south, the Muensterland Basin passes into the Rhenish Massif, a part of the Rhenohercynian Zone. DEKORP 2Q connects the Muensterland 1 borehole in the west with the other drilling Versmold 1 in the east, thus permitting the correlation of the DEKORP data with the industrial seismic network of northern Germany (Franke et al., 1990).
