Abstract
—In addition to the near normalincidence observations within the German DEKORP 2 project in 1984 wideangle observations have been carried out on a parallel profile across the boundary between the Saxothuringian and Moldanubian crust approximately 50 km NE of the main transect to control threedimensional variations Explosion sources have been used for the entire survey providing excellent conditions for wideangle registrations A velocity model has been derived on the basis of in and offline refraction measurements using a kinematic raytracer which was extended to three dimensions by interpolation of 2D velocity fields between parallel sections Although prestackmigration of the data led to aliasing effects due to large shot and geophone spacing stable results were obtained by forming envelopes after singleshot migration The migrated sections reveal a strongly reflective Moho at about 31 km depth and a steeply 50° dipping intracrustal reflector which seems to be related to the border between the two Variscan units
