- only a few strong reflections between 1 and 2 s TWT in the northwestern part of the profile,
- strong subhorizontal reflector below the Stavelot-Venn Anticline between 1.2 and 1.3 s TWT, changing into SE-dipping reflections below Monschau with an angle
- detachment of the Aachen Thrust, which can be traced laterally over 20 km,
- steepening of the Aachen Thrust between 1.5 and 3.2 s TWT turning into a broad reflective band with parallel reflections, also dipping to the SE,
- probably corresponding to the strongly deformed metamorphic zone along the southern limb of the Stavelot-Venn Anticline,
- ramp-like character of the Aachen Thrust between profile-km 40 and 55 and continuation down to more than 5 s TWT,
- discontinuous Moho around 9 to 10 s TWT.
- reflectivity consists predominantly of curved and dipping events,
- rather transparent upper crust in SSE,
- reflectivity hole below the Kelberg Magnetic High, => perhaps indicating the presence of an exhausted crustal magma chamber,
- strong dipping reflections on both flanks of the hole, interpreted as lateral igneous intrusions into the ductile lower crust,
- enhancement of pre-existing reflections by lithological contrasts, or
- tectonic shear movements caused by the weak magma,
- Moho reflections at ca. 10 s TWT in the NNW and between 10 to 11 s TWT in the SSE,no direct evidence for the Siegen Main Thrust.
Significant change of reflectivity north and south of the Hunsrück boundary fault:
- weak reflectivity above 5 s TWT,
- corresponding to polyphase deformed Palaeozoic rocksstrong reflections concentrated in patches below 5 s TWT:
- nearly flat reflection band at 5-6 s TWT, representing the top of the crystalline lower crust,
- highly reflective, laminated lower crust between 7 and 9 s TWT with a Moho at 9.2 s TWT.
- strongly reflective zone between 1 and 3 s TWT, dipping to the NW,
- nearly transparent wedge with 4 s TWT thickness at the southern end of the profile,
- southward dipping reflective zone between 3.5 and 6.2 s TWT,
- nearly horizontal set of reflections at 9.5 to 10.2 s TWT representing the Moho
