3-D Prestack-migration of Wide-angle Data from a Variscan Transition Zone

Bleibinhaus, F., M. Bopp, M. Simon, and H. Gebrande (1999), 3-D Prestack-migration of Wide-angle Data from a Variscan Transition Zone, Pure and Applied Geophysics, 156(1-2), 173-186, doi:10.1007/s000240050295.

Abstract
In addition to the near normal-incidence observations within the German DEKORP 2 project in 1984, wide-angle 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 three-dimensional variations. Explosion sources have been used for the entire survey, providing excellent conditions for wide-angle registrations. A velocity model has been derived on the basis of in- and off-line refraction measurements using a kinematic raytracer which was extended to three dimensions by interpolation of 2-D velocity fields between parallel sections. Although prestack-migration of the data led to aliasing effects due to large shot and geophone spacing, stable results were obtained by forming envelopes after single-shot migration. The migrated sections reveal a strongly reflective Moho at about 31 km depth and a steeply (50 degrees) dipping intracrustal reflector, which seems to be related to the border between the two Variscan units.
