Seismic imaging of the overdeepened basin of Lienz (Austria)

In 2016, the Leibniz Institute for Applied Geophysics (Hannover, Germany) carried out two seismic surveys in the Lienz basin. The measurements are part of a DFG-funded project, which investigates the benefit of the application of modern multi-component reflection seismics preparatory to scientific drilling, in particular to the ICDP-project DOVE (Drilling Overdeepened Alpine Valleys). Four P-wave seismic profiles, perpendicular to the valley axes, were recorded using vibroseismic technique to gain structure and facies information. In addition, two SH-wave reflection seismics, one 6-component profile, two small 3-D layouts for P-wave and S-waves, as well as one P-wave and SH-wave refraction seismic profiles were measured for primarily methodological studies. Data show a good quality and, in a first quality control, the bedrock as well as internal structures of the basin are imaged.
