As part of the German Continental Reflection Seismic Program (DEKORP), the deep seismic reflection profiles GRANU-9501 and MVE-90 were acquired in the Saxothuringian Zone to gain insights into the region’s crustal structure including the Moho. The GRANU-9501 profile is situated in the Thuringian-Franconian-Vogtland Slate Mountains. The east-west oriented MVE-90 crosses GRANU-9501 in the SW Vogtland almost perpendicularly.
The development of advanced seismic processing and imaging methods, as well as the increase in computational capacities enabled us to re-process these datasets to obtain an improved image of the crust and upper mantle in the area.
We applied Kirchhoff prestack depth migration as well as Fresnel-Volume-Migration approaches and compiled the results to a pseudo-3D image together with additional geophysical and geological information.
The results came recently into focus as profiles GRANU-9501 and MVE-90 cross the hidden Schönbrunn/Eichigt granite complex. This pluton is the investigation area of the project E4Geo, in which the principal aim is to get a better understanding of deep fault-bound hydrothermal systems related to this granite complex.
In this talk, we will present the seismic images obtained from re-processing compared to previous results as well the resulting geological interpretation and open questions.
