The most important results of DEKORP 2S are predominantly SE-dipping reflectors indicating flat-and-ramp tectonics and a differentiation into a highly reflective lower crust and a less reflective upper crust. This structural fabric extends to the NW as shown by the line DEKORP 2N.

In addition:

  • SE-dipping thrusts in the upper crust mark the boundary between Saxothuringian and Rhenohercynian below the Spessart Mountains,
  • a concentration of diffraction effects occurs in the lower crust (5 - 10 s TWT), predominantly vertically arranged and possibly related to
    • post-Variscan extensional or wrench faulting or
    • ramps and horsts of the Saxothuringian/Moldanubian thrust system.



Münsterland Cretaceous Basin:

  • strong reflections in the upper crust (0 to 4 s TWT) => Upper Cretaceous sediments over folded Carboniferous rocks
  • poor reflectivity of the lower crust
  • weak Moho reflections at ca. 11 s TWT (more than 30 km depth)

Rhenish Massif:

  • SE-dipping reflections in the upper crust represent lithologic contrasts as well as thrust faults known from surface geology,
  • highly reflective lower crust with strong, predominantly SE-dipping reflectors => flat-and-ramp tectonics
  • Moho reflections at ca. 26 km deepening to the NW


  • highly reflective coal-measures beneath the Cretaceous cover, truncated by normal faults with apparent dips to the NE,
  • prominent reflections within the upper crust (2.5 s TWT) in the SW and NE which probably correspond to the Devonian platform carbonates,
  • strong reflections in the middle crust (between 5 and 6 s TWT) which were interpreted as the top of Cadomian basement.
